The efficacy of intravaginal 15 methyl prostaglandin F2alpha methyl ester in first and second trimester abortion.

Fifteen methyl prostaglandin F2alpha methyl ester prepared within a silastic device for intravaginal administration appears to be advantageous. This study describes the technique carried out and the results observed in 50 patients. The analogue is prepared in 1.0% and 0.5% delivery systems. Twenty-four patients received the 1.0% dosage schedule and all twenty-four patients aborted. Twenty-six patients received 0.5% and twenty-three patients aborted. The coagulation millieu and other parameters were similar to that reported for other prostaglandins.
