Meptazinol, sold under the brand name Meptid, is an opioid analgesic developed by Wyeth in the 1970s.[1] Indications for use in moderate to severe pain, most commonly used to treat pain in obstetrics (childbirth).

Meptazinol is a 3-phenylazepane derivative, whereas the other phenazepanes like ethoheptazine and proheptazine are 4-phenylazepanes.

A partial μ-opioid receptor agonist, its mixed agonist/antagonist activity affords it a lower risk of dependence and abuse than full μ agonists like morphine. Meptazinol exhibits not only a short onset of action, but also a shorter duration of action relative to other opioids such as morphine, pentazocine, or buprenorphine.[2]
