Misoprostol is as effective as gemeprost in termination of second trimester pregnancy when combined with mifepristone: a randomised comparative trial.

A prospective randomized study was conducted to compare the efficacy of misoprostol with gemeprost when combined with mifepristone for termination of second trimester pregnancy. Patients requesting termination of second trimester pregnancy were randomized into two groups. In both groups of patients, 200 mg of mifepristone was given 36 to 48 hours before the administration of prostaglandins. In Group 1, the women were given 400 micrograms of oral misoprostol every 3 hours up to 5 doses. In Group 2, patients were given 1 mg of vaginal gemeprost every 6 hours up to 4 doses. The main outcomes measured were the induction-abortion intervals (the interval between the first dose of prostaglandin and abortion) and the incidence of side effects. Altogether, 50 subjects were recruited with 25 women in each group. The mean age and parity of the women and the mean gestational age of the two groups of women were comparable. There was no significant difference in the median induction-abortion intervals (8.7 hours in Group 1 and 10.8 hours in Group 2) or the incidence of side effects between the two groups of patients. We conclude that misoprostol is as effective as gemeprost in termination of second trimester pregnancy when combined with mifepristone.
