Etonitazene is a potent and selective mu-opioid agonist. It was developed in CIBA. Administration of etonitazene may induce respiratory depression, and therefor etonitazene is not used in humans. Etonitazene is explicitly listed as an illegal drug under UN convention and is illegal throughout the world.

Sample Use Guides

In Vivo Use Guide

In rat tail-withdrawal assay, etonitazene was administered subcutaneously. ED50 was 0.38 mg/kg.

Route of Administration: Other

In Vitro Use Guide

Binding of etonitazene to mu-opioid receptors from the membrane fraction of rat brains (minus cerebellum) was studied using [3H]DAMGO as a radioligand. Etonitazene binds to mu-opioid receptors with Ki of 0.5 nM.
