Mifepristone + Misoprostol
Pharmacology
Mifepristone: Mifepristone is a synthetic steroid with anti-progestational activity results from competitive interaction with progesterone at progesterone-receptor sites. Based on studies with various oral doses in several animal species, the compound inhibits the activity of endogenous or exogenous progesterone and the Menstrual Regulation (MR) results. During pregnancy, the compound sensitizes the myometrium to the contraction-inducing activity of prostaglandins. Misoprostol: Misoprostol is a synthetic analogue of prostaglandin E1. It causes myometrial contraction by interacting with specific receptors on myometrial cells. This interaction results in a change in calcium concentration, thereby initiating muscle contraction. By interacting with prostaglandin receptors, Misoprostol causes the cervix to soften and the uterus to contract, resulting in the expulsion of the uterine contents.

Side Effects
Mifepristone: Although specific drug or food interactions with Mifepristone have not been studied, on the basis of this drug's metabolism by CYP 3A4, it is possible that Ketoconazole, Itraconazole, Erythromycin and grapefruit juice may inhibit its metabolism (increasing serum levels of mifepristone). Misoprostol: Misoprostol has not been shown to interfere with the beneficial effects of aspirin on signs and symptoms of rheumatoid arthritis. Misoprostol does not exert clinically significant effects on the absorption,blood levels and antiplatelet effects of therapeutic doses of aspirin.
Pregnancy And Lactation
Administration of Mifepristone is contraindicated in patients with any one of the following conditions: History of allergy or known hypersensitivity to Mifepristone, Misoprostol or other prostaglandin, confirmed or suspected ectopic pregnancy or undiagnosed adnexal mass (the treatment procedure will not be effective to terminate an ectopic pregnancy), IUD in place, chronic adrenal failure, haemorrhagic disorders or concurrent anticoagulant therapy, inherited porphyria, If a patient does not have adequate access to medical facilities equipped to provide emergency treatment of incomplete process, blood transfusions and emergency resuscitation during the period from the first visit until discharged by the administering physician.
Therapeutic
Mifepristone: The treatment procedure is designed to induce vaginal bleeding and uterine cramping necessary for Menstrual Regulation (MR). Commonly reported side effects were nausea, vomiting and diarrhoea. Pelvic pain, fainting, headache, dizziness, and asthenia occurred rarely. Misoprostol: Gastro-intestinal side-effects like diarrhoea, 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).
Storage Conditions
Pregnancy- Mifepristone: is indicated for Menstrual Regulation (MR) (through 63 days pregnancy) and has no other approved indication for use during pregnancy. Patients who have an ongoing pregnancy at the last visit have a risk of foetal malformation resulting from the treatment. Surgical termination is recommended to manage Menstrual Regulation (MR) treatment failures. Lactation- Mifepristone: It is not known whether Mifepristone is excreted through human milk. Many hormones with a similar chemical structure, however, are excreted in breast milk. Since the effects of Mifepristone on infants are unknown, breast-feeding women should consult with their doctor to decide if they should discard their breast milk for a few days following administration of the medications. Misoprostol: Although it is not known whether Misoprostol or Misoprostol is excreted through human milk, Misoprostol should not be administered to nursing mothers because the potential excretion of misoprostol acid could cause diarrhoea in nursing infants.
