Ethoheptazine is an analgesic, which belongs to the proheptazine group. It was used either alone (Zactane trade name) or in combination with meprobamate and aspirin (Equagesic) for the pain relief in patients with headache or musculoskeletal disorders. Currently all mediactions containing ethoheptazine are withdrawn from the market. The exact target of ethoheptazine is unknow, but it is believed that it may have modulatory effect on opioid receptors.
