In a significant move to address the ongoing opioid crisis in the United States, the U.S. Food and Drug Administration (FDA) has approved Zurnai, the first nalmefene hydrochloride auto-injector. This newly approved device is designed for the emergency treatment of known or suspected opioid overdoses in adults and pediatric patients aged 12 years and older.

The approval of Zurnai adds a critical tool to the arsenal of overdose reversal options, complementing the previously available nasal spray formulation of nalmefene approved by the FDA in May 2023. The opioid crisis remains a significant public health challenge, with more than 107,000 reported fatal overdoses in 2023 alone, primarily driven by synthetic opioids like illicit fentanyl.

A New Weapon in the Fight Against Opioid Overdoses

Nalmefene is an opioid receptor antagonist, effective in reversing the life-threatening effects of an opioid overdose, such as respiratory depression, sedation, and low blood pressure. Zurnai, the newly approved product, delivers 1.5 milligrams of nalmefene either subcutaneously or intramuscularly, allowing for rapid response in emergency situations. The device is a single-dose, pre-filled auto-injector available only by prescription.

FDA’s Commitment to Combating the Overdose Crisis

The approval of Zurnai aligns with the FDA's broader efforts under its Overdose Prevention Framework, launched in 2022. This initiative focuses on expanding access to life-saving overdose reversal agents like naloxone and nalmefene. "The FDA remains focused on broadening access to opioid overdose reversal agents," stated FDA Commissioner Robert M. Califf, M.D. "Today’s approval adds a new nalmefene product and route of administration to support greater options for opioid overdose reversal."

Safety and Efficacy

The FDA's approval of Zurnai is supported by extensive safety and pharmacokinetic studies, including trials involving healthy individuals who use opioids recreationally to assess the rapid onset of the drug's effects. However, the administration of nalmefene to opioid-dependent individuals may trigger withdrawal symptoms, such as body aches, fever, nausea, and increased blood pressure. Other common adverse reactions include dizziness, nausea, headache, and irritability.

Fast Track and Priority Review

The FDA granted Zurnai Fast Track and Priority Review designations, expediting its development and review due to its potential to significantly improve the treatment and prevention of opioid overdoses. Purdue Pharma L.P., the company behind Zurnai, has been granted approval to bring this life-saving product to market.

As the opioid crisis continues to ravage communities across the U.S., the approval of Zurnai marks a critical step forward in the fight against overdose deaths. By expanding the availability of effective reversal agents like nalmefene, the FDA aims to reduce the devastating toll of opioid overdoses and save countless lives.
