Montezuma's Revenge: FDA to Limit Diarrhea Pills

By Pat Anson, Editor

Federal efforts to combat the opioid crisis entered a surprising new phase today, with the Food and Drug Administration asking Johnson & Johnson and other drug makers to limit the number of anti-diarrhea pills they sell.

You read that right.

FDA commissioner Scott Gottlieb, MD, said the “unprecedented and novel action” was needed because Imodium and other over-the-counter formulations of loperamide are being abused by opioid addicts.  

The FDA wants J&J and other drug makers to limit the number of pills in loperamide packaging so that there are just enough to treat short-term diarrhea, such as traveler’s diarrhea. – also known as Montezuma’s Revenge.

“Abuse of loperamide has been increasing in the United States. When used at extremely high and dangerous doses, it’s seen by those suffering from opioid addiction as a potential alternative to manage opioid withdrawal symptoms or to achieve euphoric effects of opioid use,” Gottlieb said in a statement.

“When higher than recommended doses are taken we’ve received reports of serious heart problems and deaths with loperamide, particularly among people who are intentionally misusing or abusing high doses.”

Last year the FDA added a warning label to loperamide products cautioning consumers not to ingest high doses. The agency believes further safety measures are needed to make it harder for people to buy loperamide in large quantities. The FDA is suggesting that loperamide be sold in packages containing a two day supply of eight 2-milligram capsules. Imodium packages currently contain as many as 42 capsules.

“The abuse of loperamide requires the purchase of extremely large quantities. Often this is done through the purchase of large bottles of loperamide, which is a common configuration in which the pill form of the medication is currently packaged,” said Gottlieb. “Today’s action is intended to change how the product is packaged, to eliminate these large volume containers. We know that many of the bulk purchases of these large volumes are being made online through major online web retailers.”

The FDA is also considering changes in how opioid medication for acute short-term pain is packaged. Several states have enacted laws that require first time prescriptions for acute pain be limited to 5 or 7 days’ supply

“If more immediate release opioid drugs, in particular, were packaged in three or six-day blister packs; then more doctors may opt for these shorter durations of use. Additionally, provided the FDA concluded that there was sufficient scientific support for these shorter durations of use, this could provide the basis for further regulatory action to drive more appropriate prescribing,” Gottlieb said.

Some users of Imodium are unhappy the medication now comes in blister packs – saying the packages are too hard and frustrating to open at an urgent time of need.

“There's nothing worse than having diarrhea and you can't get the package open,” one woman wrote on the Imodium website. “The only way I can get it open is to find a pair of scissors and cut it open. I tried one time to tear it open with my teeth and ended up cutting my lip.”

“Your product inside the box is quite good. I just wonder who convinced Imodium powers that be to change the blister units in which the caplets are packaged. I have almost lost my religion trying to tear open at the suggested/new perforation. It is horrible!” another woman wrote.

“Had to make 3 trips to the bathroom while trying to get the caplet wrapper open, packaging needs changing,” said another reviewer.

Does Genetic Testing for Opioid Addiction Really Work?

By Roger Chriss, Columnist

Prescient Medicine recently announced LifeKit Predict, a gene screening test to determine who is at risk for opioid addiction. The company states that it “can identify with 88% specificity that someone may have a risk for opioid dependency” and “provides assurance -- with 97% sensitivity -- that an individual may not have increased genetic risk for opioid dependency.”

Those are strong claims. The idea that medical conditions and behavior can be predicted by gene variants is appealing. But any such test has to answer two questions:

Is it possible in principle? And does it work in practice?

Genes and Behavior

The pathway from gene variant to behavior is very complicated. Research on the genetics of opioid addiction has found “evidence for genetic susceptibility to substance use disorders” in twin studies, but non-genetic factors are known to play a significant role as well.

Moreover, the connection between gene test results and clinically useful information is complicated. Genetic testing often finds pathogenic variants with no clinical significance. A person can be a perfect match for a rare disorder in the most advanced genetic test available but have no symptoms, so at a clinical level that person does not have the disorder. Only in a handful of cases does a specific gene variant lead to a precise fate: Huntington's disease is the standard example in textbooks.

Addiction is generally thought of in terms of the biopsychosocial model of medicine, as Maia Szalavitz explains in her book, Unbroken Brain.

“There are three critical elements to it; the behavior has a psychological purpose; the specific learning pathways involved make it become nearly automatic and compulsive; and it doesn’t stop when it is no longer adaptive,” she wrote.

The National Institute on Drug Abuse reports that “genetic factors account for between 40 and 60 percent of a person’s vulnerability to addiction; this includes the effects of environmental factors on the function and expression of a person’s genes.”

Thus, genes may play a significant role, but many other factors are also at work. A genetic test to identify an increased risk for opioid addiction is plausible in principle. But non-genetic factors make it tricky in practice.

Real World Performance

Prescient Medicine has not yet validated its product with large-scale testing in the clinical setting. There have been no clinical studies of efficacy, nor real-world reports of success or failure rates with the LifeKit Predict tool. These findings are important to know for effective use.

In research published on LifeKit Predict, Prescient acknowledges that “the use of genetic algorithms to determine predictive risk scores is still a relativey [sic] new science. Prospective, longitudinal studies are needed to better definne [sic] the breadth of the test’s importance."

A prospective trial of chronic pain patients with LifeKit Predict to see who develops opioid use disorder would be optimal. But for a variety of reasons, including ethical considerations, this test may not be practicable. Instead, Prescient could test people on long-term opioid therapy who did not develop opioid use disorder and compare the results with people who did develop opioid use disorder. Findings here would shed light on the validity of the 16 gene alleles that Prescient is using.

For now, Prescient is reporting on sensitivity and specificity. These two terms have a precise meaning in statistics, but the following medical example captures the essentials:

A molar (butterfly) rash is very sensitive for lupus but not very specific. It is rarely seen in any disorder other than lupus, so if a person has it, lupus should be suspected. But it is only seen in about half of people with lupus, so not having a butterfly rash doesn't mean you can rule out lupus.

But the sensitivity and specificity of LifeKit Predict in the ranges given by Prescient represent a significant risk for false positives and false negatives, potentially limiting the real-world value of the test.

GenomeWeb reported that Yale University professor Joel Gelertner, an expert in genetics and addiction, was skeptical that LifeKit’s “predictive power would hold up when applied to larger datasets, and argued that in the absence of better validation, physicians should not use this type of testing."

Further, LifeKit has not been compared with established tools for opioid risk assessment. The Current Opioid Misuse Measure (COMM-9) and the Opioid Risk Tool (ORT) are both simple and familiar instruments for evaluating the major risk factors for opioid use disorder.

Both COMM-9 and ORT are very inexpensive, easy to use, and give results quickly. By contrast, a gene test is expensive and requires weeks to get results. It is not clear at this point if a gene test offers any advantages over these existing instruments.

Opioid addiction risk is at present more readily assessed using tools that are already available and understood. Prescient has developed a novel and intriguing new tool, but still must prove its reliability in clinical settings before the costs and risks of such a test can be justified.

For now it is probably premature to expect this kind of genetic testing to be as useful as it would need to be to be adopted clinically.

FDA Warns Promoters of Herbal Addiction Treatments

By Pat Anson, Editor

The U.S. Food and Drug Administration is following through on its threat to crackdown on companies selling kratom and other herbal supplements as treatments for opioid addiction and withdrawal.

The FDA and the Federal Trade Commission (FTC) have sent joint warning letters to the distributors of 15 herbal supplements for illegally marketing unapproved products.

“The FDA is increasingly concerned with the proliferation of products claiming to treat or cure serious diseases like opioid addiction and withdrawal,” said FDA Commissioner Scott Gottlieb, MD. “People who are addicted to opioids should have access to safe and effective treatments and not be victimized by unscrupulous vendors who are trying to capitalize on the opioid epidemic by taking advantage of consumers and selling products with baseless claims.”

The companies used websites or social media to make claims about their products' ability to cure, treat or prevent opioid withdrawal and addiction.

TaperAid, for example, claims its “17 all-natural organic herbs” can relieve symptoms of withdrawal and even reduce tolerance to opioid painkillers.

“Use of TaperAid may increase sensitivity to opioids. You may need to lower your usual intake of opioids to account for reduced tolerance,” the company claimed. “People using short acting opioids (which includes many pain management medications and heroin) will notice a significant lowering of tolerance to their opiate of choice.”

TaperAid’s website and Facebook account have been taken down, although a TaperAid review can still be found on YouTube.

“Opioid addiction is a serious health epidemic that affects millions of Americans,” said acting FTC Chairman Maureen Ohlhausen. “Individuals and their loved ones who struggle with this disease need real help, not unproven treatments.”

In addition to the warning letters, the FTC released a “fact sheet” warning consumers about companies that promise miracle cures or fast results.

“Dietary supplements – such as herbal blends, vitamins, and minerals – have not been scientifically proven to ease withdrawal or to treat opioid dependence,” the FTC warned. “Products like Kratom, which some claim can help, are actually not proven treatments, and can be addictive and dangerous to your health.”

The FDA issued a public health advisory about kratom last November, saying there was “no reliable evidence to support the use of kratom as a treatment for opioid use disorder.”

Kratom comes from the leaves of a tree that grows in southeast Asia, where it has been used for centuries for its medicinal properties.  Millions of Americans have discovered kratom in recent years, and use it to treat addiction, chronic pain, anxiety and depression. The herb is not approved by the FDA for any medical condition. 

In 2016, the Drug Enforcement Administration attempted to list kratom’s two active ingredients as Schedule I controlled substances, which would have made it a felony to possess or sell kratom. The DEA suspended its plan after a public outcry, saying it would wait for a scheduling recommendation and medical evaluation of kratom from the FDA. Over a year later, that report has still not been released.

Opioid Commission Member Calls Panel a ‘Charade’

By Pat Anson, Editor

The Trump Administration and Congress have so neglected the country’s opioid crisis that they have turned the work of the president's opioid commission into a "charade" and a "sham," according to one panel member.

In a wide ranging interview with CNN, former Democratic Rep. Patrick Kennedy lamented a lack of focus and funding the opioid crisis has received since President Trump declared the overdose and addiction epidemic a national public health emergency last October.

"This and the administration's other efforts to address the epidemic are tantamount to reshuffling chairs on the Titanic," said Kennedy.

"The emergency declaration has accomplished little because there's no funding behind it. You can't expect to stem the tide of a public health crisis that is claiming over 64,000 lives per year without putting your money where your mouth is."

PATRICK KENNEDY

Without funding and resources, Kennedy said he believes the opioid commission's work had become a charade.

"I do. I honestly do. It means nothing if it has no funding to push it forward.... this thing's a charade,”” he told CNN. "I have to be true to the way I feel. This is essentially a sham."

President Trump appointed the bipartisan panel in March to give him a list of recommendations to combat drug addiction and the overdose crisis. 

COMMISSION on combating drug abuse and the opioid crisis

After a series of public hearings, the commission released its final report in November, an ambitious list of over four dozen recommendations aimed at treating addiction, preventing overdoses, and further restrictions on opioid prescribing.

But since the report’s release, little money has been set aside by Congress or the administration to implement the panel’s recommendations, except to increase border security and detect illegal drugs.

Last week President Trump proposed cutting the budget of the White House Office of National Drug Control Policy – which oversaw the opioid commission’s work -- by 95 percent.  After a year in office, the president has yet to appoint a permanent director for the office, which currently has a 24-year old deputy chief of staff fresh out of college with no prior experience in management or drug control policy.

"Everyone is willing to tolerate the intolerable -- and not do anything about it," said Kennedy, who is recovering from alcohol and opioid addiction, and is a prominent mental health advocate.

“I'm as cynical as I've ever been about this stuff,” he said. “We've got a human addiction tsunami, and we need all hands on deck."

Bertha Madras, another member of the opioid commission, told CNN the panel has never received any direct feedback from Trump about its work. But she praised the selection of presidential advisor Kellyanne Conway as the key point person for the administration in dealing with the opioid crisis.

"That is really a very significant issue, bringing the implementation directly into the White House, as opposed to having intra-agency meetings," said Madras, a professor of psychobiology at Harvard Medical School. "Having been in government 10 years ago or so, I know how difficult it is to be able to generate change without having executive leadership behind you."

When asked by CNN about Kennedy's critique, she praised him for the "passion and depth he brings to the problem," but said it was premature for her to comment until she sees how much money is eventually allocated for the opioid crisis.

Teen Misuse of Rx Opioids at Historic Lows

By Pat Anson, Editor

Misuse of opioid pain medication by American teenagers is at an historic low, according to a nationwide survey that also found prescription painkillers have become increasingly harder for teens to obtain.

Nearly 44,000 students in 8th, 10th or 12th grade were questioned about their drug use in the University of Michigan’s annual Monitoring the Future (MTF) survey. Overall, the number of teens drinking, smoking and abusing drugs is at the lowest level since the 1990’s, although marijuana use spiked upward in 2017.

While the so-called opioid epidemic continues to make national headlines, misuse of prescription painkillers by teenagers has been steadily falling for over a decade.

The survey found that 4.2% of 12th graders used “narcotics other than heroin” in the past year, down from 9.4% in 2002.

Only 35.8% of high school seniors said the drugs were easily available in the 2017 survey, compared to more than 54 percent in 2010.

“We’re observing some of the lowest rates of opioid use that we have been monitoring through the survey. So that’s very good news,” said Norah Volkow, MD, director of the National Institute on Drug Abuse. "The decline in both the misuse and perceived availability of opioid medications may reflect recent public health initiatives to discourage opioid misuse to address this crisis."

The misuse of the painkiller Vicodin continues a decade long decline, falling to 2.9% of high school seniors in 2017. That’s down from 10.5% of seniors in 2003. Similar declines were reported in the misuse of OxyContin.

Marijuana use by teenagers rose by 1.3% to 24 percent in 2017, the first significant increase in seven years.

“This increase has been expected by many,” said Richard Miech, lead investigator of the study. “Historically marijuana use has gone up as adolescents see less risk of harm in using it. We’ve found that the risk adolescents see in marijuana use has been steadily going down for years to the point that it is now at the lowest level we’ve seen in four decades.”

For the first time, the survey asked students about vaping.  Nearly 28 percent of high school seniors said they had used a vaping device in 2017. A little over half said the mist they inhaled was "just flavoring," about a third said they inhaled nicotine, and 11% said they vaped marijuana or hash oil.

After years of steady decline, binge drinking appears to have hit bottom. Nearly 17 percent of 12th graders said they had five or more alcoholic drinks in a row sometime in the last two weeks. That’s a lot, but it's down from 31.5% in 1998.

FDA Head Tweets New Warning About Kratom

By Pat Anson, Editor

The head of the Food and Drug Administration is warning again about the marketing of kratom and other dietary supplements to treat opioid addiction – calling them “health fraud scams.”

“FDA believes strongly people addicted to opioids should have access to safe and effective, approved treatments for addiction. Unfortunately, unscrupulous vendors are trying to capitalize on opioid epidemic by illegally marketing products for these purposes,” FDA commissioner Scott Gottlieb, MD, warned on Twitter Friday.

Gottlieb was reacting to a story in The New York Times about the marketing of dietary supplements like “Opiate Detox Pro,” a blend of vitamins and amino acids said to have “amazing benefits” in reducing opioid withdrawal symptoms. 

Similar claims are made about kratom by websites such as HowtoQuitHeroin.com, which was founded by Jorge Fernandez, a recovering heroin addict.

“Kratom works. Kratom helps. It can help you to quit heroin. It can help you to quit Suboxone. It can help you to quit Oxycontin. And believe it or not, it can even help you to quit Methadone as well,” Fernandez claims.

Kratom is not approved by the FDA as a treatment for opioid addiction or any other health condition. But because kratom is classified as a dietary supplement, it’s not held up to the same regulatory standards as pharmaceutical drugs -- as long as vendors don’t make any misleading claims about its health benefits. That’s when the FDA can intervene by seizing kratom products or prohibiting their sale.

“They’re marketing products as dietary supplements with unproven claims about ability to treat addiction; or as all-natural alternatives to opioids. Health fraud scams like these can pose serious health risks,” Gottlieb tweeted. “FDA will continue to act when it learns of the deceptive sale or advertising of products that claim to effectively treat opioid use disorder, but which have not been proven safe and effective for these purposes.”

SCOTT GOTTLIEB, MD

Although Gottlieb didn’t specifically name kratom as one of those “health fraud scams,” there’s little doubt that’s one of the supplements he was referring to. Last month the FDA issued a public health advisory about kratom, warning that it was addictive and linked to dozens of overdose deaths.

“The FDA knows people are using kratom to treat conditions like pain, anxiety and depression, which are serious medical conditions that require proper diagnosis and oversight from a licensed health care provider,” Gootlieb said at the time.

“I understand that there’s a lot of interest in the possibility for kratom to be used as a potential therapy for a range of disorders. But the FDA has a science-based obligation that supersedes popular trends and relies on evidence.”

Kratom comes from the leaves of a tree that grows in southeast Asia, where it has been used for centuries for its medicinal properties. The leaves are usually ground up to make tea or turned into powder and used in capsules. Most kratom users say the herb has a mild analgesic and stimulative effect, similar to coffee.

In a survey of 6,150 kratom users last year by Pain News Network and the American Kratom Association, most said they used kratom as a treatment for chronic pain, depression or anxiety. But a fair number -- nearly 10 percent -- said the primary reason they used kratom was to treat opioid addiction.

“Kratom is the one thing that has kept me from using opiates and other illegal substances. I've been able to stay clean for 3 years now. It's given me my life back,” one survey respondent wrote.

“Kratom is the only reason I was finally able to end my addiction to hydrocodone. It is nowhere near as potent as hydrocodone, and you can't overdose” said another.

“It has saved my life. I am a mother of four and have anxiety, depression, acute back pain, and I am an opioid addict. It has kept all these at bay for me,” one woman wrote. “I want to be there for my children, but the sad truth is I know I can't live with these conditions and not find something. It's a sad day when I have to turn to the streets again to have any kind of life.”

“I've had several friends who have died from heroin overdose if they knew about kratom they may still be alive today,” wrote another kratom user.

Last year, the Drug Enforcement Administration attempted to list kratom’s two active ingredients as Schedule I controlled substances, which would have made it a felony to possess or sell kratom. The DEA suspended its plan after a public outcry and lobbying campaign by kratom supporters, saying it would wait for a medical evaluation and scheduling recommendation for kratom from the FDA. Although the FDA has warned the public about using kratom, its full report and recommendations have yet to be released.

3 Reasons the Opioid Crisis is Getting Worse

By Roger Chriss, Columnist

The opioid crisis is now a public health emergency. The CDC reports increasing rates of fentanyl overdoses.  And The Economist warns the crisis is entering “a new and deadlier phase.”

The strategy to stop the overdose epidemic has largely focused on the supply side: limiting access to prescription opioids. History seems to support this idea. Two hundred years ago, a tincture of opium called laudanum was widely used to treat all kinds of ailments.  The “epidemic of laudanum” didn’t end until 1906, when the federal government got involved and started regulating opium-based medications.

So it seemed natural to curtail opioid prescribing. Washington State issued prescription opioid guidelines in 2010, Oregon in 2012, and the CDC in 2016. Other states followed with laws limiting the number of days opioids could be prescribed for short term, acute pain. Health insurers like Kaiser Permanente and Intermountain Healthcare have also reduced coverage of prescription opioids and drug store chains like CVS will be limiting prescription length and dose. 

In a narrow sense, this is working. Prescription opioid levels peaked in 2010, as a result of lower production quotas mandated by the DEA and reduced prescribing in a variety of clinical settings.

But in a broader sense, the focus on prescription opioid levels is failing. Opioid addiction and overdose rates continue to climb, despite the reduced availability of prescription opioids. There are three reasons for this.

First, the main drivers in the crisis are now heroin and illicit fentanyl. Importantly, heroin is increasingly the first opioid of abuse.

“As the most commonly prescribed opioids - hydrocodone and oxycodone - became less accessible due to supply-side interventions, the use of heroin as an initiating opioid has grown at an alarming rate,” researchers recently reported in the journal of Addictive Behaviors.

Second, according to the National Survey on Drug Use and Health, approximately 75% of all opioid misuse starts with people taking medication that was not prescribed to them. These pills are sourced from friends, stolen from other people’s prescription bottles, or purchased online illegally.

Contrary to common belief, opioid therapy for chronic pain conditions rarely leads to misuse or addiction. Most addictive behaviors start during adolescence, usually with substances like alcohol or tobacco, long before anyone gets their hands on opioid medication.

Third, nearly 10% of drug overdoses are intentional.

"Hidden behind the terrible epidemic of opioid overdose deaths looms the fact that many of these deaths are far from accidental. They are suicides,” wrote Dr. Maria Oquendo, President of the American Psychiatric Association, in a blog for the National Institute on Drug Abuse.

In other words, the crisis may have started with prescription opioids, but it has evolved. We are now facing a crisis driven primarily by heroin, illicit fentanyl, and other street drugs, as well as social and economic conditions that have led to an "epidemic of despair."

Therefore, the current intense focus on prescription opioids -- from the CDC’s Rx Awareness campaign to the recommendations of the President Trump’s opioid commission -- is woefully off target. Reducing access to prescription opioids has not decreased addiction and overdose rates, and may actually be making them worse.

Exactly what will be required to end the crisis is not clear. But an essential step is to understand the nature of the crisis as it stands today so as to end the opioid disconnect.

Trump Commission Seeks More Limits on Rx Opioids

By Pat Anson, Editor

President Trump’s opioid commission released its final report Wednesday, an ambitious list of over four dozen recommendations aimed at treating addiction, preventing overdoses, and further restrictions on opioid prescribing.   

“This crisis can be fought with effective medical education, voluntary or involuntary changes in prescribing practices, and a strong regulatory and enforcement environment,” the commission said in its report.

The president established the commission in March to give him a list of recommendations to combat drug addiction and the overdose crisis. 

“Our people are dying. One hundred seventy-five people a day, every day, are dying in the United States from this epidemic,” said commission chairman Gov. Chris Christie of New Jersey, one of five politicians who served on the six member panel.

“If a terrorist organization was killing 175 Americans every day on American soil, what would you be willing to pay to make it stop? I think we’d be willing to do anything and everything to make it stop. And that’s the way we now need to see this, because this is an attack from within. We are killing ourselves.”

The commission’s 131-page report did not spell out how much money would be needed to implement the panel’s wish list of 56 recommendations.

Chief among them was to get drug makers and the National Institutes of Health to work together developing new non-opioid painkillers and addiction treatment medications.

“It is inexcusable that the major pharmaceutical companies in this country have stood on the sidelines during this crisis. And they have,” said Christie.

New Prescribing Guideline to Supplement CDC's

The commission is also recommending that a new set of guidelines for opioid prescribing be developed to “supplement” the guideline released last year by the Centers for Disease Control and Prevention.  It was not immediately clear if the new guidelines would replace, weaken or strengthen the CDC’s recommendations, or simply expand their use throughout the healthcare system.

“An updated set of guidelines for prescription pain medications should be established by an expert committee composed of various specialty practices to supplement the CDC guideline that are specifically targeted to primary care physicians,” the report says.

The commission recommended that federal regulators require patients to give informed consent about the risks and alternatives to opioid painkillers before the medication is prescribed to them. The panel also called for a new “national curriculum and standard of care” for opioid prescribers, and that pharmacists be trained to recognize and deny “inappropriate prescriptions.”

The commission urged the federal government to work with states to improve the toxicology data on overdose deaths by developing uniform forensic drug testing. Critics say the current data now being used by federal agencies is flawed or cherry-picked. 

“We do not have sufficiently accurate and systematic data from medical examiners around the country to determine overdose deaths, both in their cause and the actual number of deaths,” the report says.

No Limit on Opioid Supply for Acute Pain

The commission did not recommend that supply limits be placed on opioid prescriptions for short term pain, as many expected. Several states have already enacted 5 or 7-day limits on opioids for acute pain. The panel also did not endorse the development of marijuana-based medications, which many pain sufferers are now using as an alternative to opioids.

Most of the commission’s other recommendations deal with cracking down on drug traffickers and the illicit drug market, expanding the drug court system, and increasing access to addiction treatment.

Gov. Christie refuted criticism of President Trump for declaring the overdose crisis a public health emergency, instead of a national emergency. Only $57,000 in federal funding is currently set aside to deal with a public health emergency.

“The president did exactly what I asked him to. I wanted this to be a public health emergency because I wanted HHS (Department of Health and Human Services) to administer the funds, not FEMA (Federal Emergency Management Agency). No offense to FEMA. They’re busy with some other things and it’s not there area of expertise,” Christie said.

“Now it’s incumbent upon Congress to step up and put money in the public health emergency fund, so the president can utilize that. And that should happen without delay in the view of the commission.”

In addition to Christie, commission members include Gov. Charlie Baker of Massachusetts, Gov. Roy Cooper of North Carolina, Florida Attorney General Pam Bondi, Bertha Madras, PhD, a professor of psychobiology at Harvard Medical School, and Patrick Kennedy, a former Rhode Island congressman.

In its fifth and final hearing, the commission heard testimony from several people who lost loved ones to opioid addiction and overdose. The panel never asked for or received testimony from pain sufferers, patient advocates or pain management physicians.

Fentanyl Linked to Over Half of Opioid Overdoses

By Pat Anson, Editor

A new report from the Centers for Disease Control and Prevention shows that illicit fentanyl – not prescription pain medication -- was involved in over half of the recent opioid overdoses in ten states.

The report underscores the changing nature of the nation’s overdose crisis and how public health officials have been slow to respond to the growing role of fentanyl and other illegal opioids – focusing instead on limiting access to opioid medication.

CDC researchers say fentanyl or its chemical cousins (known as fentanyl analogs) were detected in 2,903 of 5,152 opioid overdoses (56.3%) during the last six months of 2016.

Their report on overdoses in ten states (Oklahoma, New Mexico, Wisconsin, West Virginia, Ohio, Maine, Missouri, Rhode Island, Massachusetts and New Hampshire) is the first to use toxicological and death scene evidence to characterize opioid overdoses, a method that is far more accurate than other CDC reports that rely on death certificate codes.

source: Centers for disease control and prevention

Maine, Massachusetts, New Hampshire, Rhode Island and Missouri reported the highest percentages of deaths involving fentanyl (60-90%), while New Mexico and Oklahoma had the lowest (15-25%). Fentanyl is a potent synthetic opioid that is legally prescribed to treat severe pain. The vast majority of the deaths, however, involve illicit fentanyl that has flooded the black market in recent years. 

“This analysis of opioid overdose deaths in 10 states participating in the ESOOS (Enhanced State Opioid Overdose Surveillance) program found that illicitly manufactured fentanyl is a key factor driving opioid overdose deaths and that fentanyl analogs are increasingly contributing to a complex illicit opioid market with significant public health implications,” the researchers reported.

“Illicitly manufactured fentanyl is now a major driver of opioid overdose deaths in multiple states, with a variety of fentanyl analogs increasingly involved, if not solely implicated, in these deaths. This finding raises concern that in the near future, fentanyl analog overdose deaths might mirror the rapidly rising trajectory of fentanyl overdose deaths that began in 2013 and become a major factor in opioid overdose deaths.”

The CDC recently expanded the ESOOS program to 32 states and the District of Columbia. Additional funding was also provided to improve toxicology testing for a wider range of fentanyl analogs such as carfentanil, which is estimated to be 10,000 times more potent than morphine.

The new CDC report did not detail how many of the overdose deaths involved prescription opioids. A recent report from Massachusetts  estimated that prescription opioids were involved in only about 15% of overdoses in that state, ranking well behind cocaine, benzodiazepines, heroin and fentanyl.

Although opioid prescribing has been in decline for years, public health efforts remain focused on limiting access to pain medication. As PNN has reported, the CDC recently launched a new advertising campaign that focuses exclusively on raising awareness about the risks of prescription opioids, while ignoring the role of fentanyl and heroin in the overdose crisis.

The CDC’s Rx Awareness campaign will initially run in four states -- including Massachusetts and Ohio, two of the states where fentanyl overdoses vastly outnumber those involving pain medication.

How the DEA Changed the Overdose Numbers

By Pat Anson, Editor

The Drug Enforcement Administration has released its annual report on the threat posed to the U.S. by drug trafficking and the abuse of illicit drugs.

The 2017 National Drug Threat Assessment (NDTA) has both good and bad news about the nation’s worsening overdose crisis. But like other federal agencies, the DEA has a disturbing tendency to massage statistics to make the role of opioid pain medication more significant than it actually is.

“The threat posed by controlled prescription drug (CPD) abuse is prevalent. Every year since 2001, CPDs, specifically opioid analgesics have been linked to the largest number of overdose deaths of any illicit drug class, outpacing those for cocaine and heroin combined,” the report declares.

That sure makes it sound like opioid pain medication is killing more people than ever before, doesn’t it? A closer look at the numbers and methodology used by the DEA suggests otherwise.

"Controlled prescription drugs" is a very broad category that includes not only opioid pain relievers, but anti-anxiety drugs (Valium, Xanax), stimulants (Adderall, Ritalin), and anabolic steroids. And there's plenty of evidence people are dying from those drugs as well.

This is not the first time the DEA has lumped opioid pain relievers with other drugs. In the 2016 NDTA, the DEA combined opioids with anti-anxiety drugs, but not stimulants or steroids.

A year earlier, in the 2015 NDTA, prescription opioids were in a category all to themselves.

The effect of these changing and broadening definitions is significant. Every year the overdose crisis appears to be getting worse and worse. It certainly is for deaths linked to illicit drugs like heroin, cocaine and fentanyl, but not necessarily for prescription drugs and definitely not for opioid pain medication.

One has to wonder why these definitions keep changing and distorting the true nature of the overdose crisis. Don’t take my word for it. Look at how the overdose numbers for "Selected Illicit Drugs" in 2013 have grown over the years.

In the 2015 NDTA, the DEA reported that an “opioid analgesic” was involved in the deaths of 16,235 Americans in 2013.

In the 2016 NDTA, the DEA reported that “prescription drugs” were involved in the deaths of 22,767 Americans in 2013.

And in the 2017 NTDA, the DEA reported that “medications” were involved in the deaths of 24,536 Americans in 2013. The "medications" category includes not only controlled prescription drugs, but over-the-counter drugs as well.

Simply by changing the way they counted overdoses, the DEA and other federal agencies raised the death toll for 2013 by over 8,300 people.  We’re only using 2013 as an example.  From one report to the next, overdoses grew for every other year as well.

This isn’t the first time the federal government has played around with the overdose numbers. As PNN reported, last December the CDC and the White House Office of National Drug Control Policy released three different estimates of how many Americans died in 2015 from overdoses linked to prescription opioids.  

Within one week, the overdose numbers evolved from 17,536 deaths, down to 12,700, and then back up to 15,281 deaths. To use a football metaphor, that is known as moving the goalposts.

Pain Medication Abuse Declining

A closer reading of the 2017 NDTA shows that heroin, illicit fentanyl and other illegal drugs are now driving the overdose crisis, not opioid pain medication. Less than one percent of legally prescribed opioids are being diverted to the black market. 

A recent survey of law enforcement agencies, known as the National Drug Threat Survey, found that less than 10 percent of respondents nationwide believed controlled prescription drugs were the greatest drug threat in their jurisdiction -- down considerably from 2014 when over 21.5 percent reported the same

The abuse of prescription opioids is also declining. Fewer Americans are testing positive for hydrocodone, oxycodone and other painkillers in workplace drug tests. And the number of people seeking treatment for abusing pain medication has fallen significantly. From 2011 to 2014, admissions to publicly-funded treatment facilities for prescription opioid abuse fell by nearly a third. 

“This decline can in part be attributed to CPD (controlled prescription drugs) abusers switching to heroin or other illicit opioids. Some CPD abusers, when unable to obtain or afford CPDs, begin using heroin as a cheaper alternative offering similar opioid-like effects,” said the DEA.

“Expansion of the counterfeit pill market, to include pills containing fentanyl, threatens to circumvent efforts by law enforcement and public health officials to reduce the abuse of opioid medications; the arrival of large amounts of counterfeit prescription drugs containing fentanyl on the market replaces opioid medications taken off of the street.”

Curiously, the DEA report doesn’t even list kratom as a drug threat – even though the agency considers the herbal supplement a “drug of concern” and tried to ban it last year. 

“I think that all of us in the kratom community have a hard time reconciling the lack of a threat listing for kratom and yet still being considered a drug of concern,” said Dave Herman, chairman of the American Kratom Association, a pro-kratom consumer group.  “The science tells us that kratom has a low potential for either abuse or addiction and we hope to see that reflected in all DEA materials.”

Whether its kratom or pain medication, the DEA and other federal agencies have a responsibility to be consistent and to get their facts right.  Inflating the overdose numbers and blaming opioid medication may make for good headlines, but it diverts funding, resources and policymakers away from other drug problems that truly need more attention. We'll never get a handle on the overdose crisis if we keep moving the goalposts.

A recent editorial in the Journal of Pain Research took the CDC to task for doing just that.

"Transparency, freedom from bias, and accountability are, in principle, hallmarks of taxpayer-funded institutions. Unfortunately, it seems that at least one institution, the Centers for Disease Control and Prevention, continues to struggle with all three," wrote researchers Michael Schatman, PhD, and Stephen Ziegler, PhD.

"What began with a prescribing guideline created in secrecy has now evolved to the use of statistical data and public statements that fail to capture not only the complexity of the problem but also the distinction between licit and illicit opioids and their relationship to the alarming increase in unintentional overdose. This is unfortunately consistent with Mark Twain’s assertion that 'there are lies, there are damn lies, and then there are statistics.'"

What is Opioid Use Disorder?

By Rochelle Odell, Columnist

You’ve probably heard or seen the phrase “Opioid Use Disorder.”  It’s a broad term currently being used to describe not only opioid addiction, but patterns of behavior that might be a sign of addiction or could lead to it.

If that sounds like they’re putting the cart before the horse, it’s because they are.

In order to understand Opioid Use Disorder, one must understand the government's stance on opioids. The National Institute on Drug Abuse – which is part of the National Institutes of Health (NIH) – lays it out in a recently revised statement on the opioid crisis:

“Every day, more than 90 Americans die after overdosing on opioids. The misuse of and addiction to opioids--including prescription pain relievers, heroin and synthetic opioids such as fentanyl--is a serious national crisis that affects public health as well as social and economic welfare."

Notice how they lump prescription pain relievers in with heroin and illicit fentanyl?  The more I research, the more I find this common thread of illogical thinking. The government consistently lumps pain medication in with illicit drugs.

Here’s another example from the NIH: 

“In 2015, more than 33,000 Americans died as a result of an opioid overdose, including prescription opioids, heroin, and illicitly manufactured fentanyl, a powerful synthetic opioid.

That same year, an estimated 2 million people in the United States suffered from substance use disorders related to prescription opioid pain relievers, and 591,000 suffered from a heroin use disorder.”

Substance use disorders “related” to pain relievers? Heroin use disorder? That got me wondering how many drug “disorders” there are.

According to the Substance Abuse and Mental Health Services Administration (SAMSHA), there are six major substance use disorders. Nearly 93,000,000 Americans have a substance use disorder of some kind:

1) Alcohol Use Disorder (AUD): About 17 million Americans have AUD. According to the CDC, alcohol causes 88,000 deaths a year. 

2) Tobacco Use Disorder: Nearly 67 million Americans use tobacco. According to the CDC, cigarette smoking causes more than 480,000 deaths a year.

3) Cannabis Use Disorder: Over 4 million Americans meet the criteria for a substance use disorder based on their marijuana use. No estimate is provided on the number of deaths caused by marijuana, if any.

4) Stimulant Use Disorder:  This covers a wide range of stimulant drugs that are sometimes used to treat obesity, attention deficit hyperactivity and depression. The most commonly abused stimulants are amphetamine, methamphetamine and cocaine. Nearly 2 million Americans have a stimulant use disorder of some kind.

5) Hallucinogen Use Disorder: This covers drugs such as LSD, peyote and other hallucinogens. About 246,000 Americans have a hallucinogen use disorder.

6) Opioid Use Disorder: Again, this covers both illicit opioids and prescription opioids. In 2014, an estimated 1.9 million Americans had an opioid use disorder related to prescription pain relievers and 586,000 had a heroin use disorder (notice the SAMSHA numbers are somewhat different from what the NIH tells us).

But what exactly is Opioid Use Disorder?  Does it mean 2.5 million Americans are addicted to opioids?

No.

The diagnostic codes used to classify mental health disorders were revised in 2013 to cover a whole range of psychiatric symptoms and treatments. Two disorders – “Opioid Dependence” and “Opioid Abuse” -- were combined into one to give us “Opioid Use Disorder.” Few recognized at the time the significance of that change, it's impact on pain patients, or how it would be used to inflate the number of Americans needing addiction treatment.

Elizabeth Hartley, PhD, does a good job explaining what Opioid Use Disorder is in an article for verywell.

Hartley wrote that Opioid Use Disorder can be applied to anyone who uses opioid drugs (legal or illegal) and has at least two of the following symptoms in a 12 month period:

• Taking more opioids than intended
• Wanting or trying to control opioid use without success
• Spending a lot of time obtaining, taking or recovering from the effects of opioids
• Craving opioids
• Failing to carry out important roles at home, work or school because of opioid use
• Continuing to use opioids despite relationship or social problems
• Giving up or reducing other activities because of opioid use
• Using opioids even when it is unsafe
• Knowing that opioids are causing a physical or psychological problem, but using them  anyway
• Tolerance for opioids.
• Withdrawal symptoms when opioids are not taken.

The last two criteria will apply to almost every chronic pain patient on a prescription opioid regimen. So might some of the others. Most of us develop a tolerance for opioids, and if they are stopped or greatly reduced, we will experience withdrawal symptoms.  We simply cannot win for losing. 

If you learn your physician has diagnosed you with Opioid Use Disorder, be sure to ask them what criteria were used and why was it selected. Ask if you should see a doctor more knowledgeable about diagnostic codes and psychiatric disorders. 

Remember, knowledge is power. Take this information with you on your next visit to the doctor if you suspect you have been diagnosed with Opioid Use Disorder and your medications have been cut or reduced.

I hope what I have written helps you further understand exactly what we are facing and why. To be honest, it makes me want to wave the white flag, but I know that cannot happen.  We have to fight. Fight for proper care for a chronic disease or condition we didn't ask for or want. We can’t live the rest of our lives in severe, debilitating pain when effective treatment is available.

What Makes Buprenorphine Risky for Pain Patients

By Jane Babin, Guest Columnist

Buprenorphine is the darling of the addiction treatment industry, rapidly replacing methadone as the "medication assisted treatment" of choice for opioid use disorder (OUD) and addiction.  

Unlike methadone, which can only be dispensed through an opioid treatment program, buprenorphine can be prescribed in the privacy of a physician's office and filled at a pharmacy.  As a class III controlled substance, prescriptions for buprenorphine can be phoned or faxed in, and scripts can be refilled up to 5 times in 6 months without a new prescription.

Class II controlled substances, like hydrocodone, oxycodone and morphine, require a new prescription each month and can neither be refilled nor phoned in.

The only federal limitations on prescribing buprenorphine for OUD is that a physician must complete mandatory education and treat only a limited number of patients (currently 275). 

Ironically, these restrictions do not apply when buprenorphine is prescribed off-label for pain, leading some physicians and patients to turn to buprenorphine for chronic pain as class II opioids become increasingly harder to get.

Yet without training on buprenorphine’s unique pharmacology and its implications, physicians treating chronic pain may be unaware of the risks it presents. Let me explain why.

Buprenorphine’s Effect on Other Opioids

Buprenorphine is an opioid that acts as an agonist of the mu opioid receptor (MOR), which causes pain relief, just like class II opioids.  It also has side effects similar to other opioids, including tolerance, dependence, abuse potential, constipation, sedation and potentially fatal respiratory depression. 

What distinguishes buprenorphine from other opioids is that it is only a partial MOR agonist (50%).  Thus the effects of buprenorphine -- both pain relief and the undesirable side effects – don’t exceed half that of other, full agonist opioids.

Buprenorphine also has a ceiling of maximum effectiveness that reaches a plateau as the dosage is increased. That ceiling is well below what can be obtained with morphine and other opioids, but the side effects can still lead to death in opioid-naïve patients.  Buprenorphine has a long plasma half life, binds very strongly to MOR, and remains bound for extended periods of time.  Its usefulness in treating OUD is believed to lie in these properties, because it activates MOR sufficiently to curb drug craving, but not enough to elicit the euphoric effects that can lead to addiction. 

When an opioid that has higher analgesic potency, but lower MOR affinity, such as morphine or heroin, is also administered, buprenorphine wins the battle to bind and remains bound to MOR.  It can displace both heroin and naloxone from MOR, but neither can displace buprenorphine.  Naloxone can be effective when co-administered with buprenorphine -- as it is in combination drugs such as Suboxone -- but not after the administration of buprenorphine. 

Buprenorphine is also a kappa opioid receptor antagonist, which is thought to further reduce euphoria and addictive reinforcement. That’s great for patients with OUD, because it helps them resist the temptation to abuse opioids, and dampens or eliminates the euphoric effect of heroin or other opioids should they relapse.  

Increasingly, buprenorphine is being advocated for chronic pain patients.  With no more "proof" of efficacy for treating chronic pain than any other opioid, it has emerged as a less objectionable opioid because it appears safer in the eyes of addiction treatment specialists, such as Dr. Andrew Kolodny, who object to full MOR agonists for chronic pain. 

Yet safety is in the eyes of the beholder.  Despite its decreased abuse potential, buprenorphine can still be abused and cause overdoses because the ceiling effect for respiratory depression does not apply universally, particularly to opioid-naïve patients and children. Buprenorphine has caused the death of at least one child from unintentional exposure. 

Buprenorphine should not be used as the first opioid prescribed for chronic pain.  Because it cannot achieve the full analgesic effects that other opioids can, there is significant risk of buprenorphine leaving pain undertreated or even untreated.  A chronic pain patient on long-term buprenorphine therapy who experiences acute or breakthrough pain may not be able to get relief by taking another opioid.  Even more disturbing is the lack of pain control in patients who need surgery, have an acute injury from trauma or an acute painful medical emergency.

Buprenorphine Injection

Recently Indivior, a spin-off of Reckitt Benckiser Pharmaceuticals (which makes Suboxone), submitted a New Drug Application to the Food and Drug Administration on a subcutaneous injection formulation of buprenorphine. 

A once-a-month injection would be a significant advance for opioid administration because it would significantly reduce the risk of diversion.  A patient could hardly be accused of giving away or selling a drug that is deposited in his body, or of taking an incorrect dose.  

For this reason alone, an opioid depot formulation for a chronic pain patient with monthly administration sounds very appealing.  It might eliminate the need for pain contracts, pill counts, urine drug testing, and other indignations chronic pain patients suffer every day.  Even if another medication was needed for breakthrough pain, and drug testing was deemed necessary, the depot formulation would provide a virtually indisputable level of medication that could serve as an "internal control" for test error.  Detecting the depot med at unexpected levels would alert the prescribing physician to the inaccuracy of the test rather than suggest misuse or abuse.

Nevertheless, buprenorphine is not the right opioid for once-a-month dosing.  In a 2015 paper, lead author Dr. Yury Khelemsky described a horrifying case that illustrates the dangers inherent in daily buprenorphine use.  In this case, a patient with a history of drug addiction who was being treated successfully with Suboxone suffered a broken neck that required emergency surgery.

During the procedure, the anesthetized patient began to move in response to surgical stimulation, i.e., due to pain.  Despite increasing the amount of two anesthetics, Propofol and Reminfentanil, the patient continued to move.  Only after receiving yet another drug (Ketamine) did the patient remain motionless during the delicate procedure.  During a subsequent back surgery following discontinuation of Suboxone and replacement with short-acting opioids, roughly half as much Propofol and Remifentanil provided adequate anesthesia without the addition of Ketamine. 

Khelemsky noted that as little as 8 mg Suboxone (one third of the daily dose the patient was receiving), blocks the activity of hydrocodone for up to five days, and recommended discontinuing buprenorphine at least 72 hours prior to elective surgery.  This is cold comfort to a patient requiring emergency surgery -- which could be anyone.  

An injectable depot formulation of buprenorphine would substantially increase the risk of severe and possibly untreatable pain in an emergency situation, since a depot, once injected, cannot simply be discontinued as a pill would be.  Indeed, surgery may be needed to remove the depot and halt continued administration, while existing amounts of long-acting buprenorphine in plasma may necessitate higher, riskier doses of anesthetic to surgically treat the acute injury -- all while risking inadequate pain treatment.

Inexplicably, the extensive prescribing information on a random sample of buprenorphine products contains no warnings to either patients or prescribers of the risk that pain relief from an acute medical condition, trauma or surgery may be inadequate, or that buprenorphine should be discontinued days or weeks before elective surgery. 

Ironically, one package insert warns that additional analgesia may be required during childbirth, yet it fails to warn of any other situation that may require analgesia, or how analgesia can be accomplished when considering the unique pharmacology of buprenorphine.  

This seems to reflect the mindset of Kolodny and others in the addiction treatment industry, who always seem to minimize the significance of even the most severe pain encountered by an individual when compared to the perceived societal consequences of addiction.  I wonder how many pain patients or addicts would choose such a long-acting opioid if they understood the possibility that their severe acute pain could not be controlled.

The FDA committee tasked with reviewing Indivior’s new drug application is taking public comments.  I urge anyone concerned about this new buprenorphine formulation, and the failure to warn of the possibility of untreatable acute pain when taking any buprenorphine product, to provide comments by clicking here.

Comments can be submitted through October 27, 2017.  If received by October 17, they will be provided to the committee, which is scheduled to meet on October 31.  Comments received after October 17 will be taken into consideration by the FDA.

What Are the Odds of Failing a Drug Test?

By Roger Chriss, Columnist

What are the odds that a person who tests positive for an illicit drug is actually using that drug?

That is a vital question in pain management and the opioid crisis, because millions of pain patients undergo drug tests regularly and some are falsely accused of failing them. The answer is not just a matter of looking at the accuracy of the test.

In a simple situation, like a toss of a coin or a roll of a die, computing the probability of an outcome is elementary. Most people realize that a toss of a coin has an equal chance of coming up heads or tails.

But drug testing is not as simple. It is an example of conditional probability. A drug test that is 95% accurate will not find drug users 95% of the time. That is because the test is applied to both drug users and non-users. We have to use a calculation known as Bayes’ Theorem to determine the real probabilities.

Bayes’ Theorem calculates the probability of one event happening given that another event has already happened. In terms of drug testing, this means the probability that a randomly selected person who has a positive test did in fact use that drug.

To perform the calculations, we need to know two things:

1. The accuracy of the drug test
2. The “base rate” at which drug use occurs in the population at large.

The accuracy of drug tests varies widely. A 2010 study estimated that drug tests generally produce false-positive results in 5% to 10% of cases and false negatives in 10% to 15% of cases.

Data on the base rate of drug use also varies. The CDC claims as many as 25% of chronic pain patients develop signs of opioid use disorder. However, a Cochrane review found addiction in less than 2% of long-term opioid users.

This gives us four general scenarios to consider when estimating the probability that a chronic pain patient with a positive test result is actually misusing opioids:

Scenario I (25% base rate; 95% accurate drug test):  90%
Scenario II (25% base rate; 90% accurate drug test): 83%
Scenario III (2% base rate; 95% accurate drug test):  29%
Scenario IV (2% base rate; 90% accurate drug test):  17%

With a high base rate of opioid misuse and a more accurate test, the probability is high at 90 percent. On the other hand, as the base rate falls and test accuracy decreases, the probability drops significantly, down to 17 percent. This means that the probability of a person getting a false positive result increases.

The Base Rate Fallacy

Bayes’ Theorem clearly shows that the base rate of drug use has a large effect on the probability that a person will get a false test result. Because clinical decisions and healthcare policy are often based on the results of such tests, knowing the probabilities is vitally important.

The base rate fallacy occurs when a decision is made without taking the real base rate into consideration. As shown above, the upper value of 25% is more than 10 times the lower value of 2 percent, indicating a high degree of uncertainty in the base rate.

Moreover, the base rate is not the same in all locations or across all populations. Drug abuse is known to be higher in some places and among some age groups. The accuracy of drug tests also represents an average, but factors such as biochemical individuality and testing conditions may influence actual performance.

Further, drug testing is not an entirely random process. For instance, prior to prescribing opioid medication, a doctor may perform a risk assessment using an Opioid Risk Tool. A doctor may also have hints that a patient is abusing opioids to motivate testing. In either case, randomness is lost and the base rate shifts.

Conditional probability produces counter-intuitive results, with a high degree of dependence on the base rate -- itself a number that requires constant attention.

The bottom line is that drug testing alone is not foolproof. Clinical judgment by experienced physicians, combined with information such as pharmacy data, pill counts and medical records, will always get better odds than drug testing alone.

Cigna Won’t Pay for OxyContin in 2018

By John Burke, Guest Columnist

A major health insurance company -- Cigna -- announced this week that they it is removing OxyContin from its list of approved medications and replacing it with another extended release oxycodone product.

“Our focus is on helping customers get the most value from their medications — this means obtaining effective pain relief while also guarding against opioid misuse," said Jon Maesner, Cigna's chief pharmacy officer.

OxyContin is the only opioid-based prescription painkiller that Cigna is removing in 2018 as "a preferred option" from its formulary, a list of medications that its health plans will pay for.

On the surface, this declaration might appear to be a great stride toward reducing prescription drug abuse. Cigna is replacing OxyContin with Collegium’s product, Xtampza ER, which is also an abuse deterrent extended release oxycodone product. 

My problem with this announcement is that OxyContin, along with the other abuse deterrent formulations (ADFs), have very little abuse issues. OxyContin certainly did up until its reformulation in August 2010, but that was over 7 years ago! Since then, there is much documentation from a variety of sources that show the diversion of OxyContin has fallen extensively.

Xtampa ER and the other abuse deterrent formulations also have little to no abuse issues since they have been on the market. 

If Cigna wants to change drugs, that’s likely a financial decision and one they should make, but please don’t tout your move as striking a blow for reducing drug diversion.

It will do nothing to reduce drug diversion, since the clear majority of diversion falls into the immediate release opioids, primarily oxycodone and hydrocodone. 

What is even more concerning to me is the vilifying of any drug that hundreds of thousands of legitimate pain patients take to live a semblance of a normal life, especially when that drug does not have a recent history of abuse and diversion. It also tends to make suspect any and all abuse deterrent products, which is deceptive at best. 

One thing the abuse deterrent formulations have done is to help narrow their focus to legitimate pain patients. Those seeking to get “high” moved to immediate release opioids or black market heroin/fentanyl combinations, not the ADF products. That’s why the FDA is now considering requiring companies that produce generic opioids to develop ADF properties for their drugs. 

No matter what Cigna declares, the bottom line is that ADF’s have been successful. They are not an end all to diversion and abuse, but they do help pain patients get easier access to pain medication. I am hoping that is everybody’s ultimate goal.

Heroin Overdoses in ER's Surpass Rx Opioid Overdoses

By Pat Anson, Editor

The number of patients admitted and discharged from U.S. hospitals for abuse of opioid pain medication has declined significantly this decade, while the abuse of heroin and illicit fentanyl has surged, according to a new study that documents the shifting nature of the nation’s overdose crisis.

Researchers at Stanford University analyzed national trends in hospital inpatient and emergency department (ED) discharges for opioid abuse, dependence and poisoning from 1997 to 2014, the last year data was available.

They found that hospital admissions for overdoses from pain medication started falling in 2010, the same year that opioid prescriptions began declining.

At the same time, hospital discharge rates for heroin poisoning increased at an annual rate of over 31 percent. By 2014, heroin overdoses exceeded those from prescription opioids in emergency rooms by almost a 2 to 1 margin.

“After 2008, ED discharge rates for heroin poisoning increased more sharply than the rates for any opioid poisoning -- signaling that the scope of heroin harm is worse than previously suggested -- while discharges for prescription opioid poisoning recently began to decline in both the ED and inpatient settings,” researchers reported in the journal Health Affairs.

“While these changes could be the result of national and local policies aimed at reducing the prescribing of opioids, the expanded availability of heroin and new lethal illicit drugs, such as nonpharmaceutical fentanyl, could mean that they are being used instead of prescription opioids.”

The findings add evidence to recent public health concerns that people misusing or addicted to prescription opioids are switching to heroin and synthetic opioids such as fentanyl because they are cheaper and easier to get.

"This suggests that the expanded availability of lethal illicit drugs are being used to replace prescription opioids in some cases," said Tina Hernandez-Boussard, PhD, associate professor of medicine, of biomedical data sciences and of surgery at Stanford University School of Medicine.

source: health affairs

The Centers for Disease Control and Prevention has been reluctant to admit that efforts to reduce opioid prescribing could be backfiring, although their own statistics indicate otherwise.  Deaths involving heroin and synthetic opioids overtook overdoses linked to prescription opioids in 2016, the same year the CDC released its opioid prescribing guidelines.

As PNN has reported,  the CDC last week launched a public awareness campaign to combat the abuse of prescription opioids, a marketing effort driven by surveys and focus groups that completely ignores the scourge of heroin and illicit fentanyl.

“The campaign does not include messages about heroin. Specificity is a best practice in communication, and the Rx Awareness campaign messaging focuses on the critical issue of prescription opioids. Given the broad target audience, focusing on prescription opioids avoids diluting the campaign messaging. Heroin is a related topic that also needs formative research and message testing,” the CDC explained.

The Stanford study found that discharge rates for prescription opioid poisonings declined annually by about 5 percent from 2010 to 2014, while discharge rates for heroin poisoning increased at an annual rate of 31.4 percent from 2008 to 2014. The trend has likely worsened since 2014, as heroin and illicit fentanyl are even more widely available on the black market.

"I'm cautiously optimistic that prescribing clinicians are positively reacting to the opioid crisis and therefore prescription opioids are contributing less to the overall drug epidemic," Hernandez-Boussard said. "That's the good news. The bad news is that although prescription opioid use decreased, heroin and methadone greatly increased.”

Anna Lembke, MD, an associate professor of psychiatry at Stanford and a board member of Physicians for Responsible Opioid Prescribing (PROP), says she has no doubt many people addicted to prescription opioids have switched to using heroin or illicit fentanyl.

"My patients have told me that's exactly what they did," said Lembke. "Heroin was cheaper and easier to get."
