Naloxone is an opioid antagonist used primarily to rapidly reverse opioid overdose. It binds to opioid receptors and can reverse and block the effects of other opioids, including respiratory depression, sedation, and hypotension. Naloxone is approved and widely used today both in emergency settings and by bystanders.
Pharmacokinetics
Pharmacokinetic parameters reported in healthy adult volunteers after intravenous administration.
