Anin (Allylestrenol) Uses, Dosage, Side Effects, Food Interaction and all others data.

Anin (Allylestrenol) is an orally active gestagen. Anin (Allylestrenol) has a pronounced pregnancy maintaining action in castrated animals without producing hormonal side-effects. In the human, premature termination of pregnancy often follows a fall in the levels of placental hormones. Anin (Allylestrenol) has been shown to stimulate the placental progesterone production in vitro & to promote the secretion of placental hormones (human chorionic gonadotrophin, human placental lactogen, oestrogens and progesterone) and oxytocinase in patients with pregnancy at risk. In aggrement to this the trophoblastic layers of the placenta show histological signs of activation. Clinical studies have indicated that Anin (Allylestrenol) is an effective & safe pregnancy preparation. Administration of Anin (Allylestrenol) in combination with bed rest can remove or prevent the threat of abortion in early pregnancy or stop threatened premature labor.

Anin (Allylestrenol) is a progestogen structurally related to progesterone that has been given in threatened and recurrent miscarriage, and to prevent premature labour. However, with the exception of proven progesterone deficiency, such use is no longer recommended. In threatened miscarriage in progesterone-deficient women a suggested dose is 5 mg three times daily by mouth for 5 to 7 days.

How Anin (Allylestrenol) works

Anin (Allylestrenol) is similar in structure and function to progesterone. Progesterone shares the pharmacological actions of the progestins. Progesterone binds to the progesterone and estrogen receptors. Target cells include the female reproductive tract, the mammary gland, the hypothalamus, and the pituitary. Once bound to the receptor, progestins like Progesterone will slow the frequency of release of gonadotropin releasing hormone (GnRH) from the hypothalamus and blunt the pre-ovulatory LH (luteinizing hormone) surge. In women who have adequate endogenous estrogen, progesterone transforms a proliferative endometrium into a secretory one. Progesterone is essential for the development of decidual tissue and is necessary to increase endometrial receptivity for implantation of an embryo. Once an embryo has been implanted, progesterone acts to maintain the pregnancy. Progesterone also stimulates the growth of mammary alveolar tissue and relaxes uterine smooth muscle. It has little estrogenic and androgenic activity.

Dosage

Anin (Allylestrenol) dosage

Anin (Allylestrenol) should be taken orally. The dose of the drug depends on the indication.

Intra Uterine Growth Retardation [IUGR]: 1 tablet three times a day at least two months. Reduce the dose if symptoms improve.

Elimination Route

The glucuronide and sulfate conjugates of pregnanediol and pregnanolone are excreted in the urine and bile. Progesterone metabolites which are excreted in the bile may undergo enterohepatic recycling or may be excreted in the feces. Progesterone metabolites are excreted mainly by the kidneys.
