Naloxone hydrochloride

Overview

Basic Info

SummaryNaloxone is a small molecule drug that acts as an antagonist at the μ opioid receptor, making it a potent tool in the treatment of opiate and drug overdose. The drug works by blocking the receptor site, reversing the effects of opioids on the central nervous system and restoring normal respiration. Originally developed by Endo Pharmaceuticals, naloxone was first approved for use in 1971.
