登记用途：Methylergometrine is a synthetic analogue of ergonovine、an alkaloid of the ergoline family that occurs in various species of vines of the Convolvulaceae (morning glory) family and in some species of lower fungi like other ergoline alkaloids. Methylergometrine is a blood vessel constrictor and smooth muscle agonist most commonly used to prevent or control excessive bleeding following childbirth and spontaneous or elective abortion. It also causes uterine contractions to aid in expulsion of retained products of conception after a missed abortion (miscarriage in which all or part of the fetus remains in the uterus) and to help deliver the placenta after childbirth. The drug is currently prepared via reaction of (+)-lysergic acid with L-(+)-aminobutanol、using different coupling reagents、and is available under the name Methergine as tablets or injection (IM or IV) or in liquid form to be taken orally. (L1918、L1923)。
