Megestrol acetate capsules

This product is a semi-synthetic progesterone derivative, which has a certain inhibitory effect on hormone-dependent tumors. Its mechanism of action is the same as that of medroxyprogesterone, which may be through the influence on the secretion of pituitary gonadotropin, controlling the development and growth of ovarian follicles, thereby reducing the production of estrogen. It acts on estrogen receptors, preventing their synthesis and reuse, interfering with their binding with estrogen, and inhibiting tumor cell growth. In addition, it can also antagonize glucocorticoid receptors and interfere with the interaction between steroid hormone receptors and regulatory proteins related to cell growth and differentiation.

The main ingredient of this product is medroxyprogesterone acetate. The chemical name of this product is: 6-methyl-17a-hydroxypregnane-4,6-diene-3,20-dione 17-acetate. Molecular formula: C24H32O4 Molecular weight: 384.52

This product is a capsule, and the contents are white or off-white powder.

It is mainly used to treat advanced breast cancer and advanced endometrial cancer, and also has a certain effect on kidney cancer, prostate cancer and ovarian cancer. It can also improve the appetite and cachexia of patients with advanced tumors.

This product must be taken under doctor's advice. Endometrial cancer and kidney cancer: 0.2-0.4g per day; breast cancer: 0.4-0.8g per day, or even up to 1g per day. Sex hormone therapy requires at least 8 to 10 weeks of treatment to respond. Palliative treatment of cachexia and pain in patients with various cancers: 0.5-1g/day. Bone marrow protection during chemotherapy for various cancers: 0.5-1g/day (from one week before chemotherapy to one week after a course of treatment).

Similar to other progesterone drugs, but generally milder. Weight gain is a common adverse reaction of this product, which is caused by an increase in body fat and body cell volume, and is not necessarily accompanied by fluid retention. For patients with advanced cancer cachexia and weight loss, this side effect is often beneficial. Thromboembolic phenomena have been rarely reported, including thrombophlebitis and pulmonary embolism. Other reactions can cause breast pain, galactorrhea, vaginal bleeding, menstrual disorders, and facial flushing. There are also adrenal cortisol effects, moon face, hypertension, and hyperglycemia. The incidence of uterine bleeding is 1-2%. Nausea and vomiting are occasionally seen, and reactions such as dyspnea, heart failure, and rash are rare.
