New naloxone nasal spray at least doubles the dose

The Food and Drug Administration today approved a naloxone hydrochloride nasal spray to treat opioid overdoses that delivers 8 milligrams of naloxone, up from 2 mg or 4 mg in previously approved products. 
“Addressing the opioid crisis is a top priority for the FDA, and we will continue our efforts to increase access to naloxone and place this important medicine in the hands of those who need it most,” said Patrizia Cavazzoni, M.D., director of FDA’s Center for Drug Evaluation and Research.
