Adverse Effects
Side effects of Mifepristone + Misoprostol :
Mifepristone: The treatment is designed to induce the vaginal bleeding and uterine cramping necessary for menstrual Regulation (MR). Commonly reported side effects were nausea, vomiting and diarrhea, pelvic pain, fainting, headache, dizziness and asthenia occurred rarely.
Misoprostol: Gastro-intestinal side effects like diarrhea, abdominal pain, nausea, flatulence, dyspepsia, headache, vomiting and constipation, shivering, hyperthermia, dizziness, pain due to uterine contractions, severe vaginal bleeding, shock, pelvic pain, uterine rupture (requiring surgical repair, hysterectomy and/or salpingo-oophorectomy).
Mechanism of Action
Mifepristone is a progesterone antagonist with antiglucocorticoid activity. It binds to the intracellular progesterone receptor where it competitively inhibits progesterone attachment. It is also a partial progesterone agonist.
Misoprostol, a synthetic prostaglandin E1 analogue, exerts its antisecretory activity by directly acting on specific prostaglandin receptors found on the surface of gastric parietal cells. It exerts its protective effects on the mucosa by replacing the prostaglandins consumed during prostaglandin-inhibiting therapies e.g. NSAIDs.
