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\u00ae (mifepristone 200mg) and Korlym\u2122 (mifepristone 300mg). Currently under investigation for use in psychotic depression (phase 3 trials)."}]
