A risk evaluation and mitigation strategy for extended-release and long-acting opioid medications has received Food and Drug Administration approval.
The move has been anticipated as an important element in an attempt to stem the swelling tide of abuse, misuse, and overdose of these prescription drugs while assuring continued access to the highly potent analgesics for patients with moderate to severe persistent pain, Dr. Margaret A. Hamburg said in a media briefing.
The new safety measures, which pertain to approximately 30 currently available medications, will require the manufacturers of the drugs to make FDA-approved education materials available to prescribers no later than March 1, 2013, via development grants to continuing education providers who will develop and deliver the training, said Dr. Hamburg, commissioner of the FDA. In addition, the risk evaluation and mitigation strategy (REMS) will include the distribution of a patient counseling leaflet to prescribers regarding the safe and effective use of the drugs; an updated, single-page medication guide for consumers, an implementation plan, and periodic assessments to evaluate the impact of the program on the safe use of these products, which the FDA will review and use to tweak the program as needed, she said.
"It is important to note that we are focusing on extended-release and long-acting opioid medications ... because these have very specific safety problems that have to be addressed very carefully," according to Dr. John Jenkins, director of the Office of New Drugs within the FDA’s Center for Drug Evaluation and Research. These drugs, including hydromorphone, oxycodone, morphine, oxymorphone, methadone, transdermal fentanyl, and transdermal buprenorphine, "can cause problems even when prescribed appropriately."
The prescriber education component of the REMS will include information regarding the risks and benefits of opioid therapy for individual patients, choosing patients appropriately, patient management and monitoring, and patient counseling, Dr. Jenkins explained. It will also include guidance on the potential for misuse, abuse, and addition, as well as recognizing evidence for these outcomes. The updated medication guide and patient counseling document will include information on how to safely use, store, and dispose of these analgesics, specific instructions for recognizing the signs of potential overdose and advice for preventing accidental exposure to family and household visitors, he said.
With respect to the assessment and auditing component of the program, the FDA has established goals, which the manufacturers are expected to achieve, for the percentage of prescribers who complete the training and for assessing prescribers’ understanding of the risk information. Participation in the educational programs is not mandatory for prescribers, Dr. Hamburg stated. The assessments are also required to evaluate whether the [REMS] adversely affect patient access to these drugs, she said. "Patients in pain must have continued assess to medications they need," she added.
The new REMS program is one component of a multiagency, national strategy unveiled by the White House in 2011 to address prescription drug abuse, "which is this country’s fastest-growing drug problem," said Dr. Hamburg, noting that opioid overdoses in particular were the cause of approximately 15,000 deaths among Americans in 2008 and nearly 16,000 in 2009. Called Epidemic: Responding to America's Prescription Drug Abuse Crisis, the national plan suggests expansion of state-based prescription drug-monitoring programs; seeks creation of recommendations for convenient and environmentally responsible ways to dispose of unused medications; and calls for legislative action to reduce "doctor shopping" and "pill mills."
In the absence of the legislative changes needed to fulfill the comprehensive White House plan, the REMS "is an important and timely step by FDA to supplement prescriber training and consumer information," R. Gil Kerlikowske, director of the White House Office of National Drug Control Policy, said during the telebriefing.
