Application

Naltrexone hydrochloride has been used:
  • as an opioid antagonist, to analyse its effect on ethanol preference using Caenorhabditis elegans as a model
  • to determine its effectiveness in reducing the preference for substance of abuse (SOA) like nicotine and cocaine using Caenorhabditis elegans as a model
  • in the preparation of combinatorial drug, PXT3003 for treating Charcot-Marie-Tooth disease 1A (CMT1A) transgenic rat model Pmp22

Biochem/physiol Actions

Competitive antagonist for μ, κ, δ, and σ-opioid receptors; has greater oral efficacy and longer duration of action than naloxone.

A bioanalytical method using high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed and validated for simultaneous quantification of heroin, its main metabolites and naloxone. In addition, naltrexone was detected qualitatively. This method was used to analyse human plasma samples from

It has been repeatedly reported that endogenous opioid pathways play an important role in ethanol drinking behaviour. In line with these findings, a non-selective opioid receptor antagonist, naltrexone, seems to reduce relapse rates in detoxified alcoholics. The aim of the
