Meptazinol Effects
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.
