Abstract:
:Prostaglandin F2 alpha was administered intraamniotically to 132 mid-first trimester gravidas to determine the dose-24-hour abortifacient response relationship. Single doses between 15-50 mg and multiple doses between 15-25 mg were administered to 3 groups each, the latter regimen at 6-hour intervals. Trials were declared a failure if abortion did not occur within 24 hours. Results indicate that over 50% of patients can be aborted within 24 hours by a variety of unaugmented prostaglandin F-2 alpha dose schedules. Parity and gestational age were found to be important variables in the dose-response relationship. Doses in excess of 25 mg in multiparas - or - = 16 weeks gestation do not appear to increase the abortion rate, while single injections above 50 mg in nulliparas 16 weeks' gestation may improve the rate. In terms of multiple-injection schedules, doses greater than 15 mg initially, with an identical dose repeated 6 hours later, probably will not increase the 24-hour abortion rate in nulliparas - or - = 16 weeks' gestation; however, doses above 25 mg, repeated in 6 hours will not improve this rate in multiparas - or - = 16 weeks' gestation. The multiple-injection technique seems to be superior for women - or - = 16 weeks' gestation. The dose schedules investigated were not associated with any serious complications and thus can be used clinically. However, comparative series of different dose schedules are necessary to verify these findings. Larger sample sizes will permit specification of the relative importance of parity, gestational age, and other conditions in modifying the dose-response relationship.
