Objective. Opioid abuse is a serious public health concern. In response, the Food and Drug Administration (FDA) determined that a risk evaluation and mitigation strategy (REMS) for extended-release and long-acting (ER/LA) opioids was necessary to ensure that the benefits of these analgesics continue to outweigh the risks. Key components of the REMS are training for prescribers through accredited continuing education (CE), and providing patient educational materials.Methods. The impact of this REMS has been assessed using diverse metrics including evaluation of prescriber and patient understanding of the risks associated with opioids; patient receipt and comprehension of the medication guide and patient counseling document; patient satisfaction with access to opioids; drug utilization and changes in prescribing patterns; and surveillance of ER/LA opioid misuse, abuse, overdose, addiction, and death.Results and Conclusions. The results of these assessments indicate that the increasing rates of opioid abuse, addiction, overdose, and death observed prior to implementation of the REMS have since leveled off or started to decline. However, these benefits cannot be attributed solely to the ER/LA opioid analgesics REMS since many other initiatives to prevent abuse occurred contemporaneously. These improvements occurred while preserving patient access to opioids as a large majority of patients surveyed expressed satisfaction with their access to opioids.
The discovery of gamma-hydroxybutyrate (GHB) over 40 years ago led to its immediate use as a general anesthetic agent. Subsequent research demonstrated that GHB is an endogenous compound in the mammalian brain and current research suggests that GHB is a probable neurotransmitter. In the United States, reports of anabolic effects lead to its misuse among body builders during the 1980's while the intoxicating properties of the drug lead to its popularization as a substance of abuse during the 1990's. GHB became associated with reports of drug-facilitated sexual assault and cases of physical dependence and withdrawal. Efforts to ban GHB caused increased use of GHB analogues and pro-drugs. Against this backdrop, GHB was being developed for the treatment of narcolepsy, leading to the approval of Xyrem (sodium oxybate) oral solution in 2002 for the treatment of cataplexy in patients with narcolepsy. A risk management program permits the safe handling and distribution of the approved product, minimizes the risk for diversion, provides professional and patient education about the risks and benefits of sodium oxybate, and includes physician and patient registries. Post-marketing surveillance indicates sodium oxybate has an acceptable safety profile and presents minimal risk for the development of physical dependence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
