title: Plasma levels of the methyl ester of 15-methyl PGF2alpha in connection with intravenous and vaginal administration to the human.
abstract: After intravenous injection of the methyl ester of 15-methyl-PGF2alpha the drug initially disappeared faster than the corresponding free acid, but still after one hour, about 1% of the active drug is circulating in plasma. Vaginal administration of single suppositories containing 1 mg of 15-methyl-PGF2alpha methyl ester and determination of plasma levels using gas chromatography-mass spectrometry demonstrated that the highest plasma levels were reached after 1.5-3 hours. Vaginal suppositories were administered according to different dose schedules for induction of abortion and plasma levels of 15-methyl-PGF2alpha and it's ester were determined. There seemed to be a gross correlation between given doses and obtained plasma level. The data will serve as basis for further development of vaginal delivery devices.
