Mechanism of action

Syntommetrine combines ergotamine (which causes sustained uterine contraction) with oxytocin (which triggers rhythmic contractions). Carbetocin is a synthetic oxytocin analogue with longer duration of action and greater stability. Both work by binding oxytocin receptors on uterine smooth muscle, promoting sustained contraction to compress bleeding vessels and control hemorrhage after delivery.
