Naltrexone Hcl Anhydrous

Drug Details

Naltrexone hydrochloride anhydrous is a white to almost white, highly hygroscopic powder that is very soluble in water and slightly soluble in alcohol. Its chemical formula is C₂₀H₂₃NO₄•HCl, and it has a molecular weight of 377.87 g/mol. As a pure opioid antagonist, naltrexone hydrochloride is used in the management of opioid and alcohol dependence by blocking the euphoric effects of these substances. It is rapidly and nearly completely absorbed when taken orally, with peak plasma levels occurring within one hour. Due to its hygroscopic nature, it should be stored in tightly sealed containers to prevent moisture absorption.
