Meptazinol (Meptid^®) is an opioid analgesic for use with moderate to severe pain, most commonly used to treat pain in obstetrics (childbirth). 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 a short onset of action, but also a shorter duration of action relative to other opioids such as morphine, pentazocine, or buprenorphine.
