网考网解析：
Ritodrine reduces frequency and intensity of uterine contractions by stimulating vitamin B 12 receptors in the uterine smooth muscle. It's the drug of choice when trying to inhibit labor. Bromocriptine, a dopamine receptor agonist and an ovulation stimulant, is used to inhibit lactation in the postpartum period. Magnesium sulfate, an anticonvulsant, is used to treat preeclampsia and eclampsia--a life-threatening form of pregnancy-induced hypertension. Betamethasone, a synthetic corticosteroid, is used to stimulate fetal pulmonary surfactant (administered to the mother). 查看试题解析出处>>
