Alestor 5 mg | PHARMACOLOGY

Allylestrenol has been found to have a relatively weak progestational effect on the human endometrium. To obtain a full secretory endometrium in oestrogen-primed castrated women or to postpone menstruation (with an oestrogen added) in normal ovulating women, doses of allylestrenol were required which were higher than those recommended for the treatment/prevention of abortion.In vitro studies have shown that allylestrenol stimulates the synthesis of progesterone in the human placenta. It also brought about a significant (p/. 0,01) increase in the production of some specific placental enzymes (cystine aminopeptidase and heat-stable alkaline phosphatase).Histological and histochemical changes indicating an increased activity have been found in the placenta, particularly in the syncytiotrophoblast of women with a normal and threatened pregnancy, treated with allylestrenol. The stimulatory effect of allylestrenol on placental function was also suggested by the increased level of placental hormones (pregnanediol, oestriol, HCG and HPL) and enzymes (oxytocinase, CAP) in the maternal urine and plasma, which followed the administration of the drug e.g. in the early weeks as well as in the last trimester of pregnancy.A study in full-term pregnant women revealed that allylestrenol in high doses (up to 100 mg daily) did suppress the intensity of spontaneous uterine contractions, but had no effect on the sensitivity of the uterine muscle to oxytocin, and no adverse effect on the progress of normal delivery.Studies in non-pregnant women with and without endocrinological disorders have shown that allylestrenol has no oestrogenic or androgenic properties and no adverse effects on the adrenal function.No abnormal liver function tests or water and salt retention were observed in healthy female volunteers (non pregnant) who were given allylestrenol.
