title: Vaginal misoprostol compared with vaginal gemeprost in termination of second trimester pregnancy. A randomized trial.
abstract: A prospective randomized trial was conducted in 140 women to compare the efficacy of vaginal gemeprost with vaginal misoprostol for termination of second trimester pregnancy. Women requesting termination of second trimester pregnancy were randomized into two groups. Group A women were given 1 mg vaginal gemeprost every 3 h for a maximum of five doses in the first 24 h, whereas group B women were given 400 micrograms vaginal misoprostol every 3 h for a maximum of five doses in 24 h. The median induction-abortion interval in the vaginal misoprostol group (14.1 h) was significantly shorter than that in the gemeprost group (19.5 h). The percentage of women who achieved successful abortion within 24 h in the misoprostol group (80.0%) was significantly higher than that in the gemeprost group (58.6%). There was no significant difference in the incidence of side effects between the two groups except for diarrhea, which was more common in the gemeprost group. The incidence of fever was more common in the misoprostol group. It is concluded that vaginal misoprostol is more effective than gemeprost in termination of second trimester pregnancy.
