Ethoheptazine[1] (trade name Zactane) is an opioid analgesic from the phenazepine family. It was invented in the 1950s[2] and is related to other drugs such as proheptazine and pethidine.[3]

Ethoheptazine produces similar effects to other opioids, including analgesia, sedation, dizziness and nausea.[4] 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.[5]

Its no longer sold in the United States however it may be sold again if the law is changed to remove the drug from the CSD.
