FDA Approves First Generics for Lyrica
/By Pat Anson, PNN Editor
The U.S. Food and Drug Administration has approved the first generic versions of Lyrica (pregabalin), a medication widely prescribed for the treatment of fibromyalgia, diabetic neuropathy and other types of chronic pain.
Lyrica has been a blockbuster drug for Pfizer since its approval in 2004, generating revenue of $4.6 billion annually. The recent expiration of Pfizer’s patent on Lyrica opened the door to much cheaper generic competitors.
A one year supply of Lyrica currently costs about $2,800 in the United States, according to Healthcare Bluebook, while a similar dose of pregabalin under the UK’s National Health Service costs about $74.
“Today’s approval of the first generics for pregabalin, a widely-used medication, is another example of the FDA’s longstanding commitment to advance patient access to lower cost, high-quality generic medicines,” Janet Woodcock, MD, director of the FDA’s Center for Drug Evaluation and Research, said in a statement.
“The FDA requires that generic drugs meet rigorous scientific and quality standards. Efficiently bringing safe and effective generics to market so patients have more options to treat their conditions is a top priority for the FDA.”
The FDA granted approvals for generic pregabalin to 9 drug makers: Alembic Pharmaceuticals, Alkem Laboratories, Amneal Pharmaceuticals, Dr. Reddy’s Laboratories, InvaGen Pharmaceuticals, MSN Laboratories, Rising Pharmaceuticals, Sciegen Pharmaceuticals, and Teva Pharmaceuticals.
Pfizer’s patent for Lyrica CR — an extended released version of Lyrica — remains in effect until April, 2021.
Side Effects
The most common side effects for Lyrica are dizziness, somnolence, dry mouth, swelling, blurred vision, weight gain and difficulty concentrating. Lyrica’s warning label also cautions users that the drug may cause suicidal thoughts in about 1 in 500 people.
Pregabalin is classified as Schedule V controlled substance in the U.S., which means it has a low potential for abuse. In recent years, however, there is growing concern that pregabalin and its sister drug gabapentin (Neurontin) are being abused and overprescribed. The drugs were recently classified as controlled substances in the UK.
Pregabalin and gabapentin were originally developed to prevent epileptic seizures, but their use has tripled over the past 15 years as more doctors prescribed them off-label as “safer” alternatives to opioids.
A recent study in the British Medical Journal found the drugs increase the risk of suicide, overdose and traffic accidents in younger people. The risks were strongest for those taking pregabalin and were most pronounced among adolescents and young adults aged 15 to 24. Patients aged 55 and older taking gabapentinoids were not at greater risk.
