Adverse Drug Reaction Classification System

Pharmaceutical Information
Drug Name Mifepristone
Drug ID BADD_D01463
Description Mifepristone is a progestational and glucocorticoid hormone antagonist. Its inhibition of progesterone induces bleeding during the luteal phase and in early pregnancy by releasing endogenous prostaglandins from the endometrium or decidua. As a glucocorticoid receptor antagonist, the drug has been used to treat hypercortisolism in patients with nonpituitary cushing syndrome. The two marketed forms of mifepristone are Mifeprex® (mifepristone 200mg) and Korlym™ (mifepristone 300mg). Currently under investigation for use in psychotic depression (phase 3 trials).
Indications and Usage For the medical termination of intrauterine pregnancy through 49 days' pregnancy. Also indicated to control hyperglycemia secondary to hypercortisolism in adult patients with endogenous Cushing's syndrome who have type 2 diabetes mellitus or glucose intolerance and are not candidates for surgery or have had unsuccessful surgery.
