Premarin Drug for Menopause: Side Effects, Dosage, & Usage
Premarin – Clinical Pharmacology
A significant degree of responsibility for the development and maintenance of the female reproductive system and the secondary sexual characteristics of endogenous estrogens. Although in the dynamic equilibrium of metabolic interconversions there are circulating estrogens, estradiol, the main intracellular human estrogen and significantly more potent than its metabolites, estrone and estriol, at the receptor level.
The main source of estrogens in a normally adult female cycling is the ovarian follicle, which releases 70 to 500 μg of estradiol daily, depending on the phase of the menstrual cycle. After menopause, the most endogenous estrogens are obtained by converting Androstenedione, secreted by the adrenal cortex, to estrone in peripheral tissues. Thus, estrone and sulfate conjugated form, estrone sulfate, are the most common circulating estrogens in postmenopausal women.
Estrogens act through binding to the nuclear receptors in the estrogen of a flexible tissue. To date, two estrogen receptors have been identified. They differ in the proportion of fabric tissue.
Circulating estrogens modulate the secretion of the pituitary gland gonadotropins, luteinizing hormone (LH) and follicle stimulating hormone (FSH), through the mechanism of negative feedback. Estrogens take measures to reduce elevated levels of these gonadotropins in postmenopausal women.
