Pregnancy termination with the PGE2-analogue SHB 286. 1978

M O Pulkkinen

A group of 94 volunteers were treated with PGE2-analogue SHB 286 at the 12+1 week of pregnancy. Of the 94 gravidas, 78 received a single extravular dose of 50-200 microgram (Mean +/- S.E. 76 +/- 7 microgram) while 16 a short intravenous infusion of 1000-2000 microgram SHB 286. Despite the single treatment and low dose, the success rate was 69% and the instillation abortion time only 15 +/- 1 hours. At 24 hours after treatment even those gravidas who failed to abort (31%) had sufficient cervical dilatation for curettage and thus could be spared from rapid surgical dilatation. Peripheral plasma progesterone and estradiol-17 beta decreased significantly at 4 hours after treatment in those gravidas who subsequently aborted. After an initial contracture response of the uterus to SHB 286, the cyclic intraterine pressure evolved gradually. In 4 hours it reached significantly higher levels in those gravidas who subsequently aborted than in those who did not.

D011374	Progesterone	The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.
