Emergent Bio Gains OTC Approval of Narcan Spray
FDA has approved Emergent BioSolutions’ Narcan 4 mg naloxone hydrochloride nasal spray, the first nonprescription over-the-counter product for reversing the effects of opioid overdose. “In accordance with a process to change the status of a drug from prescription to nonprescription, the manufacturer provided data demonstrating that the drug is safe and effective for use as directed in its proposed labeling,” an agency release says. “The manufacturer also showed that consumers can understand how to use the drug safely and effectively without the supervision of a healthcare professional.”
Last month, a joint FDA Nonprescription Drugs Advisory Committee and the Anesthetic and Analgesic Drug Products Advisory Committee Meeting unanimously voted 2/15 to recommend the approval of the product (see earlier story). The 19-0 vote came despite some panel members voicing concerns about an Emergent study that showed some users were confused by the drug’s instructions and packaging. The company agreed it would revise the labeling and packaging to address the concerns.
In reaction to the vote, the American Medical Association said: “Making naloxone over the counter is a safe and vital step to ending the nation’s overdose epidemic. This will help community-based organizations purchase and distribute naloxone to those who need it most. Rather than sitting behind a pharmacy counter, naloxone needs to be readily available to save lives.” The group urged FDA to make a quick final decision.
FDA says that OTC approval will require a “change in the labeling for the currently approved 4 mg generic naloxone nasal spray products that rely on Narcan as their reference listed drug product. Manufacturers of these products will be required to submit a supplement to their applications to effectively switch their products to OTC status. The approval may also affect the status of other brand-name naloxone nasal spray products of 4 mg or less, but determinations will be made on a case-by-case basis and the FDA may contact other firms as needed.”
