It has analgesic, sedative, hypnotic and tranquilizing effects. Its analgesic effect is weaker than pethidine, but stronger than general antipyretic analgesics. It has no respiratory depressant effect at therapeutic doses, nor does it cause gastrointestinal smooth muscle spasm. It has better effects on chronic persistent pain and dull visceral pain, but has poorer effects on acute sharp pain (such as postoperative pain, traumatic pain, etc.) and advanced cancer pain. While producing analgesic effects, it can also cause sedation and hypnosis. This may be related to inhibiting the ascending activation system of the brainstem reticular formation and blocking the function of dopamine receptors in the brain. The therapeutic dose is non-addictive.
