Objective : To demonstrate the efficacy of 800 microgram vaginal rnisoprostol tablet for second trimester pregnancy termination.
Design : Prospective descriptive study.

Subject : Pregnant women meeting the inclusion criteria including (1) singleton pregnancy with live fetus, (2) gestational age of 14-28 weeks, (3) indication for therapeutic termination, (4) closed and uneffaced cervix, (5) absence of uterine contraction and leakage of amniotic fluid, (6) no previous classical uterine scar, (7) no contraindication for rnisoprostol such as hypersensitivity.
Intervention : 800 microgram rnisoprostol tablet intravagina every 12 hours.
Main outcome measures : Mean induction delivery time, mean abortion time, maternal side effects.
Results : The mean induction delivery time was 21.38 ± 13.68 hours, mean abortion time was 21.56 ± 13.68 hours. Diarrhea was the most common side effect occuring in 40 per cent of patients.
