Application
Medroxyprogesterone acetate: Semi-Synthetic Progestational Agent
Medroxyprogesterone acetate (MPA) and megestrol acetate [M1949], semi-synthetic progestational agents, are effective hormonal treatments for metastatic breast cancer in postmenopausal women. The antineoplastic effect may result from inhibition of pituitary gonadotropin production and resultant decrease in estrogen secretion. In addition, MPA has the pregnancy maintaining effect and the anti-estrogen effect. (The product is for research purpose only.)
