Mifepristone is a progestin antagonist used in combination with Misoprostol for medical abortion. It works by blocking the effects of progesterone, leading to the breakdown of the uterine lining and cessation of pregnancy. Mifepristone is effective for terminating early pregnancies. Common side effects may include nausea and abdominal pain, but these usually resolve over time. In summary, Mifepristone is important for medical abortion procedures.
Mifepristone competitively inhibits progesterone receptors, leading to the breakdown of the uterine lining and termination of pregnancy.
