Over-the-counter overdose-reversal drug from nonprofit pharma group wins fast-track U.S. review

A pharmaceutical nonprofit was granted priority review from the Food and Drug Administration to make an inexpensive overdose-reversal drug for use without a prescription. 

Harm Reduction Therapeutics Inc. said its 3-milligram nasal spray naloxone formulation, called Rivive, had three times higher concentration in the blood of 36 participants than naloxone delivered as a shot. The company said Monday that the FDA gave it a target approval date of April 28. The FDA declined to comment.
