title: "Second generation" prostaglandins: midtrimester pregnancy termination by intramuscular injection of a 15-methyl analog of prostaglandin F2alpha.
abstract: Eighty midtrimester gravid patients were treated with prostaglandin 15(S)-15-methyl Fa alpha by repeated intramuscular injections of 250 mug at 2-hour intervals for the elective termination of pregnancy. A success rate of 97.5% was achieved, with a mean initiation-to-abortion time of 17.2 +/- 1.0 hours. Gastrointestinal side effects were prominent but no serious complications occurred. Serial serum progesterone determinations and continuous intra-amniotic pressure recording were carried out in selected cases and correlated with abortifacient activity. This method of pregnancy termination appears particularly suitable for use in the early midtrimester of gestation.
