Americans Recognize Medical Value of Marijuana

By Pat Anson, Editor

The perception of marijuana users as pot heads and lazy stoners may finally be changing to a new one: Patient.

According to a new survey by the Pew Research Center, the medicinal value of marijuana is the #1 reason why a majority of Americans now favor its legalization.

The survey of 1,500 adults found that 53% favor legalization, a dramatic shift from a decade earlier when only 32%  favored legalization.

When asked what was the main reason they support legalization now, 41% cited its medicinal benefits. Another 36% said marijuana was no worse than other drugs such as alcohol and cigarettes.

Nearly half of U.S. states have legalized medical marijuana and four states -- Colorado, Washington, Oregon and Alaska -- and the District of Columbia have passed measures to legalize its recreational use. The federal government still classifies marijuana as a Schedule I controlled substance with no accepted medical use, but in recent years has stepped back enforcement efforts in states where it is legal.

But the stigma long associated with marijuana has discouraged physicians from prescribing it and kept pharmaceutical companies from doing extensive research about its medical benefits.

Only two prescription drugs based on cannabinoids – the active ingredients in marijuana — have been approved by the Food and Drug Administration. Nabilone is a synthetic cannabinoid approved for treating nausea in cancer patients. Marinol is also used to treat nausea, and as an appetite stimulant. Both drugs can still be  prescribed “off label” by physicians to treat other conditions.

Some limited studies have found that marijuana is effective in relieving chronic pain and some of the symptoms of HIV/AIDS, cancer, glaucoma, and multiple sclerosis.

"Scientific data indicate the potential therapeutic value of cannabinoid drugs, primarily THC, for pain relief, control of nausea and vomiting, and appetite stimulation," the Institute of Medicine said in a report.

"Smoked marijuana, however, is a crude THC delivery system that also delivers harmful substances. The psychological effects of cannabinoids, such as anxiety reduction, sedation, and euphoria can influence their potential therapeutic value. Those effects are potentially undesirable for certain patients and situations and beneficial for others." 

Efforts to get a medical marijuana spray approved as a drug to treat cancer pain suffered a setback early this year when GW Pharmaceuticals (NASDAQ: GWPH) reported the results of a clinical trial showing that Sativex worked no better than a placebo in relieving cancer pain.

Sativex is getting a "fast track review" from the FDA to treat cancer pain. It is estimated that 420,000 cancer patients in the U.S. suffer from pain that is not well controlled by opioid pain medications.

U.S. Hydrocodone Prescriptions Dropping

By Pat Anson, Editor

The number of prescriptions filled in the U.S. for hydrocodone declined in 2014, the first concrete evidence that restrictions on the widely used opioid painkiller are starting to have an impact.   

According to the IMS Institute, 119.2 million prescriptions for hydrocodone pain medications were dispensed by pharmacies last year -- down from 129.5 million the year before – a decline of 8 percent. Hydrocodone is typically combined with acetaminophen in Vicodin, Lortab, Lorcet, Norco, and other hydrocodone products.

The IMS report also found that levothyroxine – a synthetic hormone used to treat thyroid deficiency -- has replaced hydrocodone as the #1 most widely filled prescription in the U.S.

The decline in hydrocodone prescriptions is striking because it was only in the last three months of 2014 that the painkiller was reclassified by the U.S. Drug Enforcement Administration from a Schedule III drug to a more restrictive Schedule II medication.

The DEA and Food and Drug Administration have been under pressure to restrict access to opioids because of the so-called epidemic of prescription drug abuse. Over 16,000 Americans die annually from painkiller overdoses, although most of those deaths involve other drugs or alcohol.

“The rise in opioid prescribing, which led to an opioid becoming America’s most prescribed medication, resulted in a public health catastrophe,” said Andrew Kolodny, MD, director of Physicians for Responsible Opioid Prescribing (PROP), which played an instrumental role in getting hydrocodone rescheduled.

“The trend is clearly moving in the right direction. I’d predict that up-scheduling will accelerate the decline in prescriptions. This will go a long way toward bringing the opioid crisis under control because with more cautious prescribing we are likely to see less new cases of opioid addiction.”

The rescheduling of hydrocodone limits pain patients to an initial 90-day supply of hydrocodone — and also requires them to see a doctor for a new prescription each time they need a refill. Prescriptions for Schedule II drugs also cannot be phoned or faxed in by physicians.

Since the rescheduling, many patients have complained that their doctors were no longer willing to prescribe hydrocodone and that pharmacists were unwilling to fill valid prescriptions. A recent survey found that many pain patients had suicidal thoughts after being denied a prescription. Others said that rescheduling hard been harmful to their relationship with their doctor.

Hydrocodone prescriptions were dropping even before the rescheduling took effect. They peaked in 2011 with nearly 137 million prescriptions filled by pharmacies.

The IMS report found that prescriptions of tramadol, a weaker Schedule IV opioid, rose by over 5% in 2014 – a possible sign that tramadol is being used as a substitute for hydrocodone. The number of tramadol prescriptions being dispensed has nearly doubled since 2010 from 28 million to over 44.2 million in 2014.

“I predicted tramadol prescriptions would increase,” said Lynn Webster, MD, past president of the American Academy of Pain Medicine and vice president of scientific affairs at PRA Health Sciences.

“I think the overall amount of opioids has declined a little.  Physicians are prescribing less because of publicity, and fear of regulatory interventions. Payers are also limiting what patients can receive. Seems inappropriate that payers have so much control.”

Total spending on all prescription medications in the U.S. rose over 10% to $373.9 billion in 2014, according to IMS, with a record volume of 4.3 billion prescriptions filled.

Researchers Say Acetaminophen Dulls Emotions

By Pat Anson, Editor

Health experts have been warning for years about the risk of liver damage caused by taking too much acetaminophen.  Now a new study is out that found a previously unknown side effect of the drug: It also dulls emotions.

Acetaminophen -- also known as paracetamol – is the world’s most widely used over-the-counter pain reliever. It is the active ingredient in Tylenol, Excedrin, and hundreds of other pain medications.

Researchers at Ohio State University conducted two studies involving over 80 college students, half of whom took a large dose of 1000 milligrams of acetaminophen and half who took a placebo. They waited 60 minutes for the drug to take effect.

The students then viewed 40 photographs from a database used by researchers to elicit emotional responses. The photographs ranged from the extremely unpleasant (crying, malnourished children) to the neutral (a cow in a field) to the very pleasant (young children playing with cats).

After viewing each photo, participants were asked to rate how positive or negative the photo was on a scale of -5 (extremely negative) to +5 (extremely positive). Then they viewed the same photos again and were asked to rate how emotional they felt, ranging from 0 (little or no emotion) to 10 (extreme amount of emotion).

Results in both studies showed that participants who took acetaminophen rated all photos less extremely than did those who took the placebo. Positive photos were not seen as positively under the influence of acetaminophen and negative photos were not seen as negatively. The same was true of their emotional reactions.

“People who took acetaminophen didn’t feel the same highs or lows as did the people who took placebos,” said Baldwin Way, an assistant professor of psychology at the Ohio State Wexner Medical Center’s Institute for Behavioral Medicine Research.

For example, people who took the placebo rated their emotional response relatively high (average score of 6.76) when they saw jarring photos of the malnourished child or the children with kittens. But people taking acetaminophen didn’t feel as much in either direction, reporting an average emotion level of 5.85 when they saw the same photos.

Neutral photos were rated similarly by all participants, regardless of whether they took the drug or not.

“This means that using Tylenol or similar products might have broader consequences than previously thought,” said Geoffrey Durso, lead author of the study and a doctoral student in social psychology at The Ohio State University.

“Rather than just being a pain reliever, acetaminophen can be seen as an all-purpose emotion reliever.”

Previous research has shown that acetaminophen reduces not only on physical pain, but also psychological pain.

“Most people probably aren’t aware of how their emotions may be impacted when they take acetaminophen,” said Way.

The study is published online in the journal Psychological Science.

Over 50 million people in the U.S. use acetaminophen each week to treat pain and fever. The pain reliever has long been associated with liver injury and allergic reactions such as skin rash. In the U.S. over 50,000 emergency room visits each year are caused by acetaminophen, including 25,000 hospitalizations and 450 deaths.

Urine Drug Test Often Gives False Results

By Pat Anson, Editor

A urine drug test widely used by pain management and addiction treatment doctors to screen patients for illicit drug use is wrong about half the time – frequently giving false positive or false negative results for drugs like marijuana, oxycodone and methadone. 

The “point-of-care” or POC tests come with immunoassay testing strips that use antibodies to detect signs of recent drug use. Physicians like the urine tests because they can be performed in their offices, are inexpensive, and give immediate results. But experts say the tests are wrong so often that no doctor should base a treatment decision solely on the results of one test. 

“Immunoassay testing has an extraordinarily high rate of false positives and false negatives as compared to laboratory testing,” said Steve Passik, PhD, Vice President of Research and Advocacy for Millennium Health, which analyzed urine samples from nearly 4,300 POC tests obtained at addiction treatment clinics.The Millennium study was published in The Journal of Opioid Management.

A false positive reading means a drug was detected that isn’t actually there, while a false negative means the POC test missed finding a drug that was present in a urine sample.

The Millennium study found plenty of both.

False positive readings for marijuana, for example, were given over 21% of the time, while false negative results for marijuana also appeared about 21% of the time.

The POC tests had an even worse track record for oxycodone, a widely prescribed opioid pain reliever. False positive results were detected over 41% of the time and false negatives over 31% of the time for oxycodone.

“We always knew it wasn’t as sensitive and we always knew that it didn’t look for specific drugs within a class. But this was revealing in regard to how much it misses, with false negative and false positives rates in 40 to 50 percent in some instances,” said Passik.

“If we were in another area of medicine, let’s say oncology, and you had a tumor marker or a test that you were going to base important treatment decisions on, and it was as inaccurate as immunoassay is, the oncologists would never stand for it.”

Passik says “the word is starting to get out” how inaccurate the immunoassay tests are. But few patients are aware of it and some doctors are still dropping patients from pain management programs after POC tests found illicit or unprescribed drugs in their urine. 

Passik told Pain News Network that patients should insist on a second test if they feel the first one is wrong.

“If they think it’s a false positive, they need to ask the doctor to be re-tested. And particularly they should ask what method was used. And if they find out they were tested with immunoassay, they should say they want the same specimen either re-tested at the lab or they want to provide another specimen tested at the lab,” Passik said.

A laboratory test that uses chromatography-mass-spectrometry to break down and identify individual molecules is far more accurate than an immunoassay POC test, but it could cost thousands of dollars -- something many insurers and patients are unwilling to pay for.

And critics say Millennium – one of the largest drug screening companies in the nation – has produced a self-serving study designed to drum up more business for itself.

“It does not surprise me that Millennium would show a high rate of inconsistencies with the POC test,” said a source with broad experience in the drug testing industry. “Remember, their business is to sell confirmation testing, so they will skew the way they present data to try to influence the market to do more confirmation testing.  In most cases, that’s how it works in any study conducted or funded by a device or pharmaceutical company.”

The source told Pain News Network the data in Millennium’s study was “skewed toward exaggeration” and questioned the need for further testing.

“In addiction centers, there is not really a large demand for confirmation testing. I understand Millennium wants to increase that business because that’s what they do.  However, medical necessity does play into all laboratory testing.  The great majority of the time, when a patient in a treatment center is confronted with the results of a POC test that shows a drug in their system that shouldn’t be there, they will confess to taking the drug.  So, what would be the medical necessity of confirming that test?

“I believe many of the urine drug testing labs are promoting confirmation testing when it is not medically necessary.”

Millennium took offense that the validity of its study was being questioned.

“Millennium Health strongly disagrees with the characterization in the story that the study was skewed or biased in any way,” the company said in a statement to Pain News Network.

“The study was accepted and published by a well-respected, peer-reviewed publication. Millennium Research Institute is committed to the highest ethical and research science standards, and we stand by the results of our study. The study was based on random samples from addiction treatment clients. The data clearly indicated that immunoassay, or point-of-care, tests have a high rate of false positives and false negatives when used to screen patients for illicit drug use.”

"Liquid Gold"

A growing number of doctors who treat addicts and chronic pain patients require them to submit to random drug screens. And some companies and government agencies also require employees and job applicants to submit to POC tests as a condition of employment.

The competition between drug screening companies for this business is intense. According to one estimate, drug testing has grown into a lucrative $4 billion dollar a year industry -- “liquid gold” as some have called it – that is projected to reach $6.3 billion by 2019.

But addiction experts say more reliable and expensive testing is needed, simply to be fair to patients.

“Heavy reliance on immunoassays in addiction treatment can be detrimental to the patient due to their higher risk for false positives and false negatives in comparison with more reliable technology, such as chromatography-mass-spectrometry,” said Michael Barnes, executive director of the Center for Lawful Access and Abuse Deterrence (CLAAD), a non-profit that gets some of its funding from Millennium.

“A false positive can be detrimental to a patient by subjecting her to unjust suspicion or accusations, unnecessary adjustments to the treatment plan, or the deterioration of the practitioner-patient relationship. A false negative may result in delayed diagnosis or misdiagnosis, false confidence that a patient has not relapsed, and failure to catch behavior that could eventual result in a preventable overdose death. Therefore, chromatography-mass-spectrometry is often more appropriate.”

Millennium’s Passik says most doctors recognize that both tests may be needed.

“These two different methods yield very different kinds of results,” Passik said. “If I was still practicing, I wouldn’t feel that immunoassay is accurate enough to be the only test that you use.”

Ironically, a federal court last year found Millennium guilty of giving illegal kickbacks to doctors by providing them with free POC test cups – the very tests the company says have an “extraordinarily high rate” of false results.

Two Drug Combo Relieves Neuropathy Pain

By Pat Anson, Editor

British researchers say a combination of two widely used drugs – an antidepressant and an opioid – can significantly relieve pain and other symptoms caused by neuropathy.

In a study published in the journal PAIN, researchers at Queens University say combining the painkiller morphine with the antidepressant nortriptyline relieved chronic neuropathic pain in nearly 90 percent of patients – significantly better than when either drug is used alone.

"Morphine and nortriptyline are excellent candidates for pain management because of the extensive research conducted on them, their low cost, and widespread availability all over the world," said Ian Gilron, MD, a professor in Queen's School of Medicine and anesthesiologist at Kingston General Hospital.

"Current neuropathic pain treatments are ineffective or intolerable for many sufferers so this new evidence supporting the morphine-nortriptyline combination is important news for patients."

Nortriptyline, an antidepressant sold under the brand names Aventyl and Pamelor, is already being used to treat pain in the arms and legs caused by multiple sclerosis. Morphine has long been used to treat both acute and chronic pain.

Neuropathic pain is characterized by tingling or burning sensations that develop as result of nerve damage caused by conditions such as shingles, diabetes, amputation, inflammation, and cancer. About 8% of adults worldwide suffer from neuropathy. Many drugs used to treat neuropathic pain, such as Neurontin and Lyrica, often don’t work or have unpleasant side effects.

In the double-blind, randomized study, 52 neuropathy patients were given a choice of trying every one of three treatments: morphine alone, nortriptyline alone, and a combination of the two drugs over six-week treatment periods. Patients were asked to record their pain levels and side effects during each treatment.

The average daily pain before treatment was 5.6, measured using a rating scale from 0-10. Average daily pain dropped to 2.6 when patients received the two drug combination. Patients taking nortriptyline and morphine alone rated their pain at 3.1 and 3.4, respectively.

Researchers said that common side effects for both drugs, which include constipation and dry mouth, did not worsen with the combined treatment.

"It's important to remember that we don't want to completely eliminate patients' ability to sense pain as it's a warning system for us, but we do want to find the right balance of pain relief and drug side effects," said Gilron

Nortriptyline and morphine are currently not available in a combined formulation. According to the Mayo Clinic, using the two drugs together is usually not recommended because they both cause sedation.

Study: One in Five Opioid Prescriptions for Low Back Pain

By Pat Anson, Editor

Doctors continue to prescribe opioids for low back pain, headaches and fibromyalgia – even though some medical guidelines recommend against their use for such common conditions, according to a large new study.

In an analysis of prescriptions filled for 12 million of its members between July 2013 and September 2014, pharmacy benefit manager Prime Therapeutics found that about one in five opioid prescriptions were written to treat low back pain.

"Our analysis found low back pain was the most common diagnosis among all members taking an opioid, even though medical guidelines suggest the risks are likely greater than the benefits for these individuals," said Catherine Starner, PharmD, lead health researcher for Prime Therapeutics.

Over 22% of those receiving long-acting opioids had been diagnosed with low back pain, nearly 5% had headache and about 2% were diagnosed with fibromyalgia.

In a position paper adopted last year, the American Academy of Neurology found there was “no substantial evidence” for long term use of opioids to treat low back pain, fibromyalgia and headache.

“Collectively, the data suggest that opioids do not improve function in low back pain and therefore should be avoided. While I am an advocate of minimizing opioids to every extent possible, I also believe that absolutes can be damaging," said Beth Darnall, PhD, a pain psychologist, clinical associate professor at Stanford University and author of Less Pain, Fewer Pills.

“In select individual cases, opioids may be one part of an effective pain management plan.  Even then, patients should be monitored closely and opioids used at the lowest dose for the shortest amount of time possible.  The opioid studies are based on large samples and there are always outliers; we must find ways of minimizing risks, protecting patients, and still leaving room for the reality that the medications may be effective for a minority of individuals.”

Nearly 9% of Prime Therapeutics’ members were prescribed at least one opioid during the study period. On average, the cost for those taking short-acting opioids was $72 per member, compared to $907 per member taking only long-acting opioids.

The company said a clinical program that assesses the appropriateness of long-acting opioids could help improve safety and reduce costs. A screening program could also identify members with a significant number of opioid claims in a short period, or those with diagnosed conditions that may not benefit from prolonged opioid use.

"Identifying these members and helping them find the most appropriate pain treatment for their condition could help reduce safety concerns," said Starner.

Darnall says an education program would also help – one that includes non-drug treatments.

“To reduce opioid prescriptions, patients must be given access to effective alternatives,” Darnall said in an email to Pain News Network. “Additionally, by providing patients with education regarding the limitations of opioids and associated risks clinicians may engage patients in their own care and motivate them to seek and try alternatives.  Such alternatives include psycho-behavioral interventions, self-management programs, graded exercise programs, rehabilitation approaches, and the like.”

Prime Therapeutics manages pharmacy claims for health insurers, employers, and government programs including Medicare and Medicaid. It is collectively owned by 13 Blue Cross and Blue Shield Plans, subsidiaries or affiliates.

Florida's State of Pain

By Pat Anson, Editor

If you suffer from chronic pain or care for someone who does, a recent half hour special report by WESH-TV in Orlando is “Must See TV” – whether you live in Florida or not.

In many ways Florida was ground-zero in the “War on Drugs,” with a sordid history of pill mills and unscrupulous doctors who dished out prescriptions for painkillers like they were candy.

In 2010, according to the Centers for Disease Control and Prevention, 98 of the top 100 oxycodone dispensing doctors in the country were in Florida and eight Floridians were dying every day from drug overdoses.

The state started cracking down. Law enforcement agencies raided doctors’ offices, shutdown over 100 pill mills, and heavily penalized pharmacies that were dispensing too many opioids.

The crackdown worked and overdoses soon declined, but somewhere along the way – in the view of many chronic pain patients -- the War on Drugs became a War on Patients. 

Florida doctors started dropping pain patients from their practices and pharmacies began turning away longtime customers who had never abused painkillers, forcing many to go on a “pharmacy crawl” in search of someone to fill their prescriptions. Faced with daily unrelenting pain, some patients resorted to suicide.

Much of what happened in Florida is now occurring on a national level, with pain patients being marginalized and viewed as drug addicts by a health care system that has grown fearful and paranoid.

WESH-TV investigative reporter Matt Grant and his producers do a commendable job covering all of this, explaining how legitimate pain patients have become unintended casualties in Florida’s War on Drugs.

From Russia with Pain

By Pat Anson, Editor

If you’re a pain sufferer who has difficulty getting prescriptions written and filled for opioid pain medication – be glad you don’t live in Russia.

In Russia, even terminally ill cancer patients have trouble getting opioids. And some have committed suicide rather than spend their remaining days in pain.

In February, 11 cancer patients committed suicide in Moscow alone, according to a special report published in Meduza, a web-based Russian media outlet that operates out of Latvia.

“There’s no end to the pain. It won’t stop next morning, or tomorrow, or the day after. It won’t disappear if a tooth is pulled out or if drops of medicine are squeezed into your ear. If you don’t relieve the pain somehow, it eats you up right to the end. It’s absolutely unbearable,” one cancer patient was quoted as saying.

Getting painkillers in Russia is difficult for everyone, whether they have cancer or not. It can take up to three days for adults, according to Meduza, and for children up to 12 days.

Here’s what cancer patients have to do:

First they visit a general practitioner at a clinic, who will assess their pain levels and send them to an oncologist. The oncologist will then write up an assessment and send the patient back to the general practitioner, who will write up a prescription. The head of the clinic must then stamp the prescription, which is only valid for five days.

Clinics typically forward prescriptions to pharmacies at 4 pm – so if a patient doesn’t have a prescription approved by then, they have to wait until the next day.

All of these steps leading to long lines at the clinic, the oncologist and the pharmacy. The final indignity for patients is that they have to return the used containers and packaging from their previous medication to get a new one.

Adding to the stigma is that narcotic painkillers have long been deemed unnecessary in Russia – dating back to Soviet times. Patients who use the drugs are often treated like addicts and doctors who prescribe narcotics are sometimes punished as criminals.

This has led to a thriving black market for painkillers and soaring prices for pain medication that are sold legally. The government is reported to be conducting checks of pharmacies in major cities to protect against price gouging.

Meduza’s story about the suicides sparked a backlash and a heavy-handed attempt by the government to prevent other websites from reporting on poor access to pain medication. The pretext given for the censorship was a 2012 Russian law that prohibits online content advocating suicide and drug use. Any website violating the law can be blocked by the government.

One site was told to delete copy that simply said: "The wife of the deceased explained that her husband suffered from constant pain because of cancer and often said he was tired of being sick."

Moscow's deputy mayor disputed the notion that the suicides were in any way connected to lack of access to painkillers -- claiming that at least seven of the 11 people who killed themselves were unaware they had cancer.

The deputy head of the Russian Federation Council's constitutional law committee disputed the notion that forcing websites to delete information would prevent more suicides.

"The information about the reasons for suicides by cancer sufferers is socially significant in this case,” Senator Konstantin Dobrynin told the state news agency RIA Novosti. “Covering up such information could lead to even more victims."

The World Health Organization ranks Russia 38th out of 43 European countries in access to painkillers, but the problem isn’t unique to Russia.

According to one recent study, pain medications such as morphine and codeine were not widely available or virtually non-existent in a dozen eastern European countries stretching from Poland to Turkey.

'National Pain Strategy' Report Released

By Pat Anson, Editor

The National Institutes of Health has quietly released a draft copy of its National Pain Strategy, a long awaited report designed to advance pain research, healthcare and education in the U.S.

The report calls chronic pain a “complex disease and a threat to public health” and identifies several areas where physicians and the healthcare system are failing pain sufferers.

“Access to high-quality integrated care based on clinical evidence is hindered by many challenges, including a payment system that does not support optimal care. Pain management often is limited to pharmacological treatment offered by a single primary care practitioner or to procedure-oriented and incentivized specialty care that is not coordinated and not aligned with the best available evidence or expected outcomes,” the report says.

“Even when interdisciplinary care is provided, creating and executing a care plan is often fragmented, with poor communication among clinicians and without consideration of patient preferences. The clinician or team’s choice of therapy may be based on practice experience or on insurance coverage, rather than one informed by a comprehensive pain assessment, clinical evidence or best practices.”

The report only briefly addresses the controversy over the abuse and diversion of opioid painkillers, and how some pain sufferers are being denied pain medication by their doctors and pharmacists.

“The reluctance of many clinicians to prescribe these medications, and patients’ concerns over stigmatization associated with opioids may jeopardize quality pain control in the population. Only a small percentage of practitioners and patients account for the majority of opioid-related risk through abuse of prescribing privileges and inappropriate management of prescriptions,” the report said.

Other key findings of the report:

• People with pain are too often stigmatized in the health care system and in society, which can lead to delayed diagnosis, misdiagnosis, and bias in treatment.
• Significant barriers to pain care exist, especially for populations disproportionately affected by pain.
• Although pain is widespread in the population, research is lacking on the prevalence, impact, and outcomes of most common chronic pain conditions.
• Significant improvements are needed in pain management practices.
• Primary care doctors are not sufficiently trained in pain assessment and treatment.  
• Greater collaboration is needed between primary care doctors and pain specialists.

“I agree that collaboration between primary and pain specialists is helpful in some cases, though I do not believe it is mandatory,” said Celeste Cooper, a retired nurse and patient advocate who reviewed the report.

“To think that a primary physician cannot complete continuing education courses for management of mild to moderate chronic pain is ridiculous. Primary physicians are on the front lines. They will be held accountable for prevention strategies, but they aren’t able to make assessments for treating pain? This seems like tying their hands behind their backs.’

The National Pain Strategy is an outgrowth of the 2011 Institute of Medicine report, “Relieving Pain in America,” which found that 100 million Americans suffer from chronic pain.

One critic of the new report says it lacks vision and will not make pain care better.

 “I think the report reflects that it has been developed by (and for) special interest groups who are not very skilled at planning or project management. This report is ungainly and lacks a real focus -- and so I think people in pain will be wondering what exactly they can expect to be different and better for them,” said patient advocate David Becker in an email to Pain News Network.

“I think it is unethical for special interest groups to assume that any and every individual in pain cannot be cured and should not receive stem cell therapy or other curative/regenerative care. In this regard, it reinforces the received view -- and a self- serving view -- that people in pain should be treated indefinitely by medical care."

While not perfect, Cooper said she was encouraged by the report's recommendations.

"Looking at chronic pain as a public health issue is the right approach in my opinion. It will avail resources that wouldn’t otherwise be accessible. The report is comprehensive, there will be roadblocks in implementing all the suggestions, but hopefully generations to come will benefit. As an educator, I was impressed on seeing short-term to long-term goals. This strategy provides a mechanism for reassessment and revision," Cooper said in an email.

The Interagency Pain Research Coordinating Committee is accepting public comments on the National Pain Strategy until May 20, 2015.

FDA Issues Guidance on Abuse Deterrent Opioids

By Pat Anson, Editor

The U.S. Food and Drug Administration has released its long-awaited guidance on abuse-deterrent opioids, beating a Congressional deadline and a potential loss of $20 million in funding.

The document “Guidance for Industry: Abuse-Deterrent Opioids – Evaluation and Labeling” explains the FDA’s current thinking about abuse-deterrent properties and recommends to drug makers how clinical studies should be conducted to evaluate their effectiveness.

Abuse deterrent formulas are intended to make it harder for drug abusers to crush or liquefy a narcotic painkiller for snorting or injecting. But the evidence is mixed that they actually work.

“It should be noted that these technologies have not yet proven successful at deterring the most common form of abuse — swallowing a number of intact capsules or tablets to achieve a feeling of euphoria. Moreover, the fact that a product has abuse -deterrent properties does not mean that there is no risk of abuse.  It means, rather, that the risk of abuse is lower than it would be without such properties. Because opioid products must in the end be able to deliver the opioid to the patient, there may always be some abuse of these products,” the FDA said in its report.

The agency has been under pressure from Congress to move faster in developing guidelines for abuse deterrence. An appropriations bill passed late last year would have moved $20 million in funding from the FDA’s Commissioner’s office if the guidance wasn’t released by June 30.

“The science of abuse-deterrent medication is rapidly evolving, and the FDA is eager to engage with manufacturers to help make these medications available to patients who need them,” said FDA Commissioner Margaret Hamburg, MD. “We feel this is a key part of combating opioid abuse. We have to work hard with industry to support the development of new formulations that are difficult to abuse but are effective and available when needed.”

So far only four opioids have been approved with abuse-deterrent formulas, OxyContin, Embeda, Targiniq and Hysingla. The latter was recently introduced by Purdue Pharma as the only “pure” hydrocodone extended release product with abuse-deterrence.

Purdue’s reformulated version of OxyContin was the first opioid to have abuse deterrence. It was introduced in 2010, at a time when the painkiller was widely being abused.

A recent study by researchers at Washington University’s School of Medicine in St. Louis found that over a quarter of drug abusers entering treatment facilities admitted they still abused OxyContin. About a third of the abusers said they had found a way to inhale or inject it. The rest took the painkiller orally.

One unintended consequence of reformulating OxyContin is that 70% of the drug abusers who stopped using it and who switched to other narcotics started using heroin.

"The newer formulations are less attractive to abusers, but the reality is -- and our data demonstrate this quite clearly -- it's naïve to think that by making an abuse-deterrent pill we can eliminate drug abuse. There are people who will continue to use, no matter what the drug makers do, and until we focus more on why people use these drugs, we won't be able to solve this problem,” said senior investigator Theodore J. Cicero, PhD, a professor of neuropharmacology in psychiatry.

Some patients believe the reformulated version of OxyContin is less effective as a pain reliever and causes gastrointestinal problems because it is harder to digest.

The FDA said it would take “a flexible, adaptive approach” to the future evaluation and labeling of abuse-deterrent products.

“Development of abuse-deterrent products is a priority for the FDA, and we hope this guidance will lead to more approved drugs with meaningful abuse-deterrent properties,” said Janet Woodcock, MD, director of the FDA’s Center for Drug Evaluation and Research.

“While abuse-deterrent formulations do not make an opioid impossible to abuse and cannot wholly prevent overdose and death, they are an important part of the effort to reduce opioid misuse and abuse.”

Over 16,500 deaths in the U.S. were linked to opioids in 2010. According to the National Institutes of Health, only about 5% of patients taking opioids as directed for a year end up with an addiction problem.

Acetaminophen Ineffective for Back Pain

By Pat Anson, Editor

The world’s most widely used over-the-counter pain reliever is ineffective in treating low back pain and provides little benefit to people with osteoarthritis, according to a new study published in the British Medical Journal.

In a systematic review of a dozen research reports (a study of studies), Australian researchers also questioned many of the conventional treatments for back pain and other musculoskeletal conditions.

Acetaminophen -- also known as paracetamol – is the active ingredient in Tylenol, Excedrin, and hundreds of other pain medications. It is often recommended by doctors worldwide for back pain and osteoarthritis.

"Clinicians should carefully weigh benefits and harms when making treatment decisions. Paracetamol is not efficacious and potentially harmful. In this context we cannot justify its continued use for these prevalent diseases,” said Professor David Hunter of the University of Sydney.

The researchers found “high quality” evidence showing that patients taking acetaminophen are at greater risk of liver toxicity and nearly four times more likely to have abnormal results from liver function tests.

"World-wide, paracetamol is the most widely used over-the counter medicine for musculoskeletal conditions so it is important to reconsider treatment recommendations given this new evidence," said lead author, Gustavo Machado of The George Institute and the University of Sydney.

Low back pain is the leading cause of disability worldwide, and osteoarthritis of the hip or knee is the 11th highest contributor to global disability.

"This latest research, the most comprehensive systematic review of its kind, reaffirms this with an even larger, global patient base, and has for the first time also established that the effects of paracetamol for knee and hip osteoarthritis are too small to be of clinical importance." said senior author Manuela Ferreira of the George Institute for Global Health and the University of Sydney.

"We urgently need to take stock of the evidence for common musculoskeletal conditions, a largely under-recognized health priority, and make sure people are receiving appropriate care."

Treatments known to be effective for low back pain include counseling, physical therapy, exercise and psychological therapies such as cognitive behavioral therapy.

Aerobic exercise, strengthening exercise, weight management and anti-inflammatory medicines have been shown to provide benefit for patients with lower limb osteoarthritis.

A recent study published in The Lancet found that acetaminophen had no effect on pain, disability, function, sleep quality, or quality of life for people with low back pain.

Over 50 million people in the U.S. use acetaminophen each week to treat pain and fever. The pain reliever has long been associated with liver injury and allergic reactions such as skin rash. In the U.S. over 50,000 emergency room visits each year are caused by acetaminophen, including 25,000 hospitalizations and 450 deaths.

Study Claims 10% of Pain Patients Addicted to Opioids

By Pat Anson, Editor

Estimating rates of opioid abuse and addiction has never been easy. Dozens of different studies have come to startling different conclusions, and there is even disagreement over the definition of abuse and addiction.

Now a professor at the University of New Mexico is weighing in on the subject -- and his conclusions are likely to stir even more debate.

In a systematic review of 38 research reports (a study of studies) published in the journal PAIN, lead author Kevin Vowles and his colleagues estimate that up to 30 percent of the opioids prescribed for pain are misused and that about 10 percent of pain patients are addicted to them.

They also question whether opioids should be prescribed at all for chronic pain.

“It is not clear whether the risks of opioid use outweigh the potential for benefit. The efficacy of opioids and their suitability for the long-term management of chronic pain still remain very much in question and while this uncertainty in effectiveness is well established, it stands in somewhat stark contrast to the clinical reality of chronic pain treatment, where rates of prescriptions have skyrocketed such that opioids are now among the most frequently prescribed medications,” wrote Vowles.

“We are not certain whether the benefits derived from opioids, which are rather unclear based on the extant literature, compensate for this additional burden to patients and health care systems.”

The researchers noted there was extremely wide variation in the rates of opioid misuse and addiction in the studies they analyzed. Rates of “problematic use” ranged from less than 1% all the way up to 81%.

One study -- a review of 25 research reports – left the barn door wide open by broadly estimating the “prevalence of problematic opioid use behavior” at 0% to 50% of pain patients.

“The vagueness inherent in these definitions, areas of overlap among them, and their sometimes interchangeable use have made it difficult to determine exact rates and types of problematic opioid use,” conceded Vowles.

Exactly what constitutes opioid misuse is also debatable.

Vowles defined misuse as “opioid use contrary to the directed or prescribed pattern of use, regardless of the presence or absence of harm or adverse effects.” Such a definition means a patient who has stopped using a prescribed opioid – even if they no longer have pain – is misusing the medication.

(Several years ago this writer was sent home from the hospital after surgery with a two week supply of Vicodin. Fortunately, the surgery was successful and the pain subsided after a few days. A half empty bottle of Vicodin sat unused in my medicine cabinet for years before I had sense enough to throw it out. Under Vowles’ definition, I had “misused” the Vicodin.)

Studies by some of the nation’s largest drug screening companies consistently show that many Americans don’t take the drugs that are prescribed for them. A large study by Quest Diagnostics found that 60% of Americans failed to take a medication as prescribed by their physicians and that 42% had no drugs in their system. Should they be included in estimates of misuse?

Rates of addiction in the studies analyzed by Vowles also varied greatly – from 0.7% of pain patients up to 34.1%.

An adjusted analysis by Vowles estimated the average rate of addiction at 8% to 12% -- a figure nearly double the estimate of the National Institutes of Health (NIH). According to the NIH, only about 5% of patients taking opioids as directed for a year end up with an addiction problem.

“Misuse, abuse and addiction mean different things to different researchers,” said Lynn Webster, MD, past president of the American Academy of Pain Medicine and vice president of scientific affairs at PRA Health Sciences.

“We must keep in mind that behaviors determine the diagnoses of misuse, abuse and addiction and these behaviors are subjective interpretations. Subjective interpretations are influenced by one's biases and perspective.  Misuse to one researcher can be addiction to another. Unfortunately there has not been a standard interpretation of behaviors and I doubt there ever will be due to personal beliefs about opioids and addiction.”  

While Webster doesn’t take issue with the design of the study – he does dispute the overall conclusion that the risks of opioid abuse outweigh the benefits.  

“It is undoubtedly true that some people should not be prescribed opioids.  But even using their reported averages for abuse and addiction, a majority of people do not abuse or become addicted and therefore shouldn't necessarily be denied treatment particularly if there is no other option,” Webster wrote in an email to Pain News Network. 

Ironically, only one study analyzed by Vowles even looked at the recreational abuse of opioids – perhaps the biggest contributor to the so-called “epidemic” of prescription drug abuse in the U.S.  That study estimated the rate of abuse by pain patients at just 8% -- far below their estimated rates of misuse.

Vowles admits there are several limitations to his study.

“The most obvious is the degree of variability within this literature. In spite of our attempts to minimize the impact of this variability, the range of misuse and addiction was incredibly broad,” he wrote.

“These sources of variability will likely continue to cloud our ability to make precise estimates. There is clearly room here for a series of carefully controlled studies where sources of variability are held constant, or as constant as possible, to more clearly illuminate prevalence rates of problematic opioid use in individuals with chronic pain.”

Survey: Two-Thirds of Patients Unable to Get Hydrocodone

By Pat Anson, Editor

About two-thirds of pain patients say they were no longer able to obtain hydrocodone after the opioid painkiller was reclassified by the U.S. government from a Schedule III medication to a more restrictive Schedule II drug, according to the results of a new survey.

Many patients who had been taking hydrocodone at the same dose for years said their doctor would no longer prescribe the painkiller. Over a quarter (27%) said they had suicidal thoughts after being denied a prescription for hydrocodone.

The survey of over 3,000 patients was conducted online by the National Fibromyalgia & Chronic Pain Association (NFMCPA) and the findings presented this week at the annual meeting of the American Academy of Pain Medicine. An abstract of “Hydrocodone Rescheduling: The First 100 Days” can be found here.

Hydrocodone was rescheduled by the Drug Enforcement Administration in October of last year to combat an “epidemic” of prescription drug abuse. The rescheduling limits patients to an initial 90-day supply and requires them to see a doctor for a new prescription each time they need a refill. Prescriptions for Schedule II drugs also cannot be phoned or faxed in by physicians.

The reclassification quickly made a drug that was once the most widely prescribed pain medication in the country – at nearly 130 million prescriptions each year – to one of the hardest to get.

Other key findings of the survey:

• 88% of respondents believe the change to Schedule II denies pain patients the right to adequate pain care.
• 75% believe the change will not prevent prescription drug abuse.
• 72% believe the change is harmful to pain patients.
• 18% said it led to a "worsened relationship" with their doctor.
• 30% reported "issues" with their pharmacy filling prescriptions.

Patients also reported higher expenses due to increased doctor’s visits, higher co-pays, greater transportation costs to visit the doctor and multiple pharmacies, and lost income due to inability to work because of pain.

The survey is believed to be the first to report on the experiences of pain patients treated with hydrocodone since the rescheduling took effect. The respondents were overwhelmingly female, which reflects the demographics of fibromyalgia and many other chronic pain conditions.

Hydrocodone isn’t the first pain medication to be in short supply. A report released last month by the Government Accountability Office (GAO) faults the DEA for poor management and “weak internal controls” of the quota system under which controlled substances are produced and distributed.

Between 2001 and 2013, the GAO said there were 87 “critical” shortages of drugs containing controlled substances, over half of them pain relievers. The vast majority of drug shortages lasted over a month and some dragged on for years. An oral solution of oxycodone was difficult to obtain for eight and a half years.

“The shortcomings we have identified prevent DEA from having reasonable assurance that it is prepared to help ensure an adequate and uninterrupted supply of these drugs for legitimate medical need, and to avert or address future shortages. This approach to the management of an important process is untenable and poses a risk to public health,” the report states.

Patients Deserve to Know the Truth about Cymbalta

By Crystal Lindell, Columnist

Look, yes, Cymbalta probably saved my life. But it also sucks. So, I’m not surprised people are suing Eli Lilly, the makers of the drug. 

I can still remember talking to a nurse over the phone at the Mayo Clinic’s pain rehab program when she mentioned Cymbalta. It was the same pain program my insurance company would eventually deny, prompting the Mayo Clinic to ask for $35,000 up-front, and prompting me to laugh in their faces and instead buy a $7 Yoga DVD at Best Buy and hope for the best. 

Anyway, yeah, the nurse. She was all, “Oh! Cymbalta is a WONDERFUL drug! So many people love it! And it works so well! That’s a great drug to go on when you go off opioids!”  

But all I could think was, “Obviously you have never been on Cymbalta or opioids or had chronic pain, because Cymbalta sucks.”

I always tell people I was tricked into starting the drug. 

My doctor, whom I really do love, put me on it about a year and a half ago. He brought it up at my first appointment with him -- the same appointment I also decided to confess that I was having suicidal thoughts daily. He told me he was putting me on Cymbalta because it had been shown to help with pain. I’d later find out that was only half the reason. 

When I went to a follow-up appointment, the doctor asked if  Cymbalta had helped with my pain at all. And because my pain is stronger than the U.S. military, it hadn’t. But, then came the reveal. 

“Well, how’s your mood?” he asked, slowly.  

“Actually, better,” I replied, realizing that had been his secret plan all along. 

But you know what? I can sincerely tell you that I didn’t want to kill myself anymore. I mean, I still thought about it, but the drug had sort of diluted the thoughts, and made them less of a legitimate option and more of a fleeting idea I had in passing. 

And I totally get why my doctor did what he did. Because when someone is suicidal, it just makes sense that staying alive is the one and only goal. So, in the beginning I was fine with whatever worked — and it just so happened that Cymbalta is what worked for me. 

Until it didn’t. 

Cymbalta was able to keep the suicidal thoughts away, but it also kept a lot of other thoughts away too. Like my creative thoughts, my writing thoughts and, honestly, my sex thoughts. The drug straight up slaughtered my sex drive.  

It also made me so tired. Like, sleep-for-16-hours-a-day tired. Yes, it had help from all the other drugs I’m on, but I can clearly tell you that the fatigue is worse than it was before I started taking Cymbalta.

So, a couple months ago I tried to go off it. I chose the only method I knew and cut it out cold turkey. Within just two days, my writing voice came back like the great flood. And I was getting turned on by my boyfriend again. I even got to see and understand 8 a.m. again for the first time in like a year. 

All was well with the world. Except when suddenly it wasn’t. Because Oh. My. God. The withdrawal symptoms from Cymbalta were hell. 

Less than a week after my last pill, I was getting so dizzy that I seriously thought I had a new disease. Then, there was this thing called the brain zaps, that I didn’t understand until they happened to me. In short, it literally felt like my brain was being, well, zapped by electricity. 

There was also nausea and vertigo and just an overall feeling of falling off a skyscraper. 

I can honestly tell you that going off Cymbalta was worse than going off any opioid I’ve ever been on. At least with opioids it only takes like 18 hours to get out of your system, and when it’s over, it’s over. Cymbalta lingered. It took it’s time with me. It gradually poured on the withdrawal symptoms in a tortuous piling on. 

So, a week after I went off it, I went back on it.

Apparently though, I’m not the only one staring down at a lifetime of daily Cymbalta doses. According to the Internet, (always a reliable source) there’s a possible class action lawsuit being brought against Eli Lilly.

“Studies show that between 50% and 78% of Cymbalta users experience antidepressant withdrawal symptoms after discontinuing the drug. Yet the drug label misleadingly states that Cymbalta withdrawal symptoms occur in only 1% to 2% of cases,” claims attorney Steven D. Gacovino.

You can read more about it here.

Now, I literally have no idea how legit this whole thing is. Can you really fill out a form on a random website and be part of  a class action lawsuit? I have no idea. But I can tell you that I totally submitted the form. 

If nothing else, doctors should be telling their patients about this. They should have a conversation that goes something along the lines of, “Hey, this drug might quell your suicidal thoughts, but you’re never going to be able to go off of it. I mean, you will, but it will be hell. You’ll probably get vertigo and brain zaps and you may not be able to stand up without falling over. Also, there’s no telling how long those withdrawal symptoms are going to last.”

If nothing else, patients deserve to know the truth. I deserved to know the truth.

Fed Report Blames DEA for Painkiller Shortages

By Pat Anson, Editor

Poor oversight by the U.S. Drug Enforcement Agency has led to a sharp increase in shortages of some prescription drugs – including many opioid painkillers – according to a new government study that calls the shortages “a risk to public health.”

The lengthy report by U.S. Government Accountability Office (GAO) faults the DEA for “weak internal controls” and poor management of the quota system under which controlled substances are produced and distributed.

Between 2001 and 2013, the GAO said there were 87 “critical” shortages of drugs containing controlled substances, over half of them pain relievers. There were also shortages of anti-anxiety medications, sedatives, and stimulants. All of the drugs belong to a class of medications that affect the central nervous system and are used to treat seizures, manage anxiety, and relieve pain.

The vast majority of drug shortages lasted over a month and some dragged on for years. An oral solution of oxycodone was in short supply over the course of four different shortages, with a combined duration of over eight and a half years.

“While we cannot establish a causal relationship between shortages of drugs containing controlled substances and DEA’s management of the quota setting process, the shortcomings we have identified prevent DEA from having reasonable assurance that it is prepared to help ensure an adequate and uninterrupted supply of these drugs for legitimate medical need, and to avert or address future shortages. This approach to the management of an important process is untenable and poses a risk to public health,” the report states.

The shortages have only grown worse in recent years, according to many pain patients, physicians and pharmacists, who say controlled substances such as hydrocodone are increasingly difficult to obtain in some parts of the country.

The DEA has blamed major pharmacy chains such as CVS and Walgreens for some of the shortages, claiming the companies made a “business decision” not to fill as many prescriptions for opioids, after they were fined tens of millions of dollars for violating rules for dispensing controlled substances.

But even small, independent pharmacies have complained that controlled substances are harder to obtain. In a 2013 survey of over 1,000 pharmacists, the National Community Pharmacists Association (NCPA) found that most had experienced delays of at least one week in obtaining shipments of painkillers and other controlled substances.

“Community pharmacists repeatedly cited having their supplies or shipments of controlled substances abruptly shut off by their wholesalers, which may have done so due to perceived pressure, intimidation or a lack of clear guidance from law enforcement officials, such as the Drug Enforcement Administration,” said B. Douglas Hoey, CEO of NCPA, which represents over 23,000 independent pharmacies.

Under federal rules, the manufacture and distribution of controlled substances is regulated by the DEA under a quota system to discourage diversion, while the Food and Drug Administration regulates what conditions the medications can be taken for. Drug manufacturers are required every year to apply to the DEA for quotas to make their drugs, but according to the GAO the DEA rarely responds in timely manner.

“Manufacturers who reported quota-related shortages cited late quota decisions as causing or exacerbating shortages of their drugs,” the GAO said.

The DEA and FDA are supposed to work together when shortages of controlled substances develop, but according to the GAO they do not have a “sufficiently collaborative relationship” and even “disagree about what constitutes a shortage.”

The inter-agency rivalry has at times led to finger pointing.

“DEA officials also said that they do not believe FDA appropriately validates or investigates the shortage information it posts on its website and that posting this information encourages manufacturers to falsely report shortages to obtain additional quota. However, FDA reports that it takes steps to investigate and confirm the shortages on its website,” the GAO report states.

The GAO recommended the DEA perform periodic data checks to better manage the quota process, improve the processing of quota applications, and do a better job coordinating with the FDA on how to handle drug shortages when they develop.
