Ethoheptazine

Ethoheptazine[1] (trade name Zactane) is an opioid analgesic from the phenazepane family.

[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.

Revocation of FDA Approved Medications Status stems from a combination of efficacy vs. toxicity, and the more-varied and historically safer benzodiazepines class.

[7] The controlled status (Schedule IV) of Equagesic was due to the meprobamate content.
