Biological Activity
| Description | Ulipristal acetate (CDB-2914, HRP 2000, RU 44675) is a selective SPRM for emergency contraception after an unprotected intercourse or contraceptive failure. | |

| Targets |
|
|
| In vitro | Ulipristal acetate has partial agonistic as well as antagonistic effects on the progesterone receptor. It also binds to theglucocorticoid receptor, but has no relevant affinity to the estrogen, androgen and mineralocorticoid receptors.[1] | |
| In vivo | Based on clinical trials, ulipristal acetate seems to be a reasonably tolerable and effective method of emergency contraception when used within 120 hours of intercourse. Ulipristal acetate is at least as effective as LNG when used within the first 72 hours after unprotected intercourse. However, ulipristal acetate may be more effective than LNG when used between 72 to 120 hours after unprotected intercourse, extending the window of opportunity for emergency contraception. [2][3] |
