Nifedipine is a caclicum channel blocker and used for treatment of hypertension,its use as inhibitor of uterine contraction is not prcaticed widely, since its effectivness in preventing preterm labour is not fully established,its use usually started late in pregnancy after the period of organogensis and so far no deletrious effects seen with its use wether as a hpotensive agent or as inhibitor for uterine contractions,but it may reduce the mother's blood pressure to the extent it could affect the blood flow the baby with decrease oxygenation of the baby, so it should be monitored carefully >
