[Extraamniotic induction of abortion with a new prostaglandin E-2 derivative].

First clinical results are reported of a new prostaglandin-E2-derivative (16-phenoxy-prostaglandin-E2-methylsulfonylamide = SHB 286) as abortifacient using the extraamniotic route of application. Upon investigation in animals this prostaglandin-E2-derivative proved to be more tissue-selective and more potent in inducing abortion than the naturally occurring prostaglandins. Prostaglandin SHB 286(50 or 100 microgram) was applicated to 31 patients for legal abortion and to 7 patients with a missed abortion. The mean instillation-abortion time was 14.2 and 13.7 h respectively. 96% of the patients had a complete or incomplete abortion after 24 hours. Severe local or systemic side effects did not occur and the patients did not need any further medication.
