Etonitazene, also known as EA-4941 or CS-4640, is a benzimidazole opioid, first reported in 1957, that has been shown to have approximately 1,000 to 1,500 times the potency of morphine in animals.

Because it is characterized by a strong dependency potential and a tendency to produce profound respiratory depression, it is not used in humans. It is, however, useful in animal models for addiction studies, particularly those requiring the animals to drink or ingest the agent, because it is not as bitter as opiate salts like morphine sulfate.
