title: Termination of early gestation with a vaginal polysiloxane device impregnated with (15S)-15 methyl prostaglandin F2alpha methylester.
abstract: An investigation of the abortifacient activity of (15S)-15 methyl prostaglandin F2alpha methyl ester released from a vaginal polysiloxane device was performed in eleven pregnant women of 49 days gestation or less. Bleeding and contractions were induced in all women, but only seven aborted their pregnancies. Five subjects received a vaginal device impregnated with 3 mg of drug and two aborted fetal tissue. Six women were given a vaginal device containing 5 mg of drug and five aborted fetal tissue. Ten of the patients had significant side effects, nausea, emesis, diarrhea and chills. Six women expelled the device prior to the termination of therapy. This prostaglandin analogue, when administered from a vaginal polysiloxane device in early gestation was an effective abortifacient but was accompanied by systemic side effects and a high incidence of expulsion of the device prior to its scheduled removal.
