Ulipristal powder is a selective progesterone receptor modulator used for the purposes of emergency contraception (Ella) and for the treatment of uterine fibroids (Fibristal). It is a derivative of 19-norprogesterone and has both antagonistic and partial agonist activity at the progesterone receptor. It also binds to glucocorticoid receptor, however compared to mifepristone (a progesterone receptor antagonist), ulipristal is more tolerable and has lower glucocorticoid activity and better binding affinity.
