Ulipristal Acetate Usage And Synthesis
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.
