Ulipristal acetate Description
 Ulipristal acetate (UPA) is a selective progesterone receptor modulator. Attributing to its higher efficacy and a similar rate of side effects compared to levonorgestrel emergency contraception, it is now recommended as first line treatment for emergency contraception. Emergency contraception is defined as the use of drug or device after unprotected or under-protected intercourse to prevent an unwanted pregnancy. Ulipristal acetate can be used up to 5 days (120 h) after unprotected sexual intercourse.
 As progesterone promotes the growth of uterine fibroids, the blocking characteristic of ulipristal acetate can thereby be used to reduce the size of uterine fibroids. Ulipristal acetate has also shown efficacy with a significant reduction in uterine bleeding caused by uterine fibroids. The treatment of fibroids by ulipristal acetate should begin in the first week of a menstrual period.
 Drugs or herbal products that induce enzymes, including CYP3A4, such as carbamazepine, phenytoin, rifampin, St. John's Wort, etc., may decrease the plasma concentrations of ulipristal acetate, and may decrease its effectiveness while CYP3A4 inhibitors such as itraconazole, ketoconazole, etc., may increase plasma concentrations of ulipristal acetate.
 The half-life after oral intake is 32 h; it binds to plasma proteins for 97–99%, and it is metabolized by the citochrome P450.


Ulipristal acetate Applications:
 (1).Α selective labelled progesterone receptor modulator
 (2).Ulipristal acetate is a selective progesterone receptor modulat

Ulipristal acetate Function:
 Ulinastal acetate is a new oral contraceptive pill, and it is the active chemical composition of Ella, a new generation of emergency contraceptive wildly on the market in United States currently. It can protect women within 120 hours after intercourse without medication, and the emergency contraceptive efficacy will not decline with the delay of treatment time. At the same time, it is safe and durable. Compared with the most commonly used emergency contraceptive levonorgestrel, Ulinastal acetate is more suitable for clinical use, and has the potential to prevent more unwanted pregnancies.
 Ulipristal acetate was developed by HRA Pharmaceuticals, Inc., and was marketed by the Food and Drug Administration (FDA) in August 2010 under the trade name Ella. It could be used for the protection of unprotected sex or for the pregnancy prevention in the known or suspected contraceptive failure situation within 120h. Ulipristal acetate is a selective progesterone receptor modulator; and mainly it can take effect by inhibiting the ovulation and plays an emergency contraceptive effect. The study found that Ulastatal acetate was more effective than levonorgestrel in suppressing vomiting after dosing before the estimated ovulation day. And it consequently suggests that Ulatastatin acetate might have a stronger emergency contraceptive effectiveness.
