Ethoheptazine

Ethoheptazine (trade name Zactane) is an opioid analgesic from the phenazepine family. It was invented in the 1950s and is related to other drugs such as proheptazine and pethidine.

Ethoheptazine produces similar effects to other opioids, including analgesia, sedation, dizziness and nausea. It was sold by itself as Zactane, and is still available as a combination product with acetylsalicylic acid and meprobamate as Equagesic, which is used for the treatment of conditions where both pain and anxiety are present. It was also investigated for use as an antitussive.
