Tác dụng
Description:
Mechanism of Action: Allylestrenol is a synthetic progestogen structurally related to progesterone. It exhibits trophoblastic, placentotrophic, and β2-adrenergic activity with no androgenic action. Allylestrenol stimulates the hormonal effects of existing syncytiotrophoblast which are necessary for progesterone production. The pregnancy-maintaining effect is due to the stimulation of the placental function, and the stimulation of β2-adrenergic receptors prevents uterine contractility. |
