Correct Answer: All of the above
Description: Ans is 'd' i.e.,All of the above Medical methods of first-trimester abortion o Mifepristone (RU-486) and Misoprostol: Mifepristone an analog of progestin (norethindrone) acts as an antagonist, blocking the effect of natural progesterone. Addition of low-dose prostaglandins (PGE1) improves the efficiency of first-trimester abortion. It is effective for up to 63 days and is highly successful when used within 49 days of gestation. o PROTOCOL: 200 mg of mifepristone orally is given on day 1. On day 3, misoprostol (PGE1) 400 g orally or 800 g vaginally is given. The patient remains in the clinic for 4 hours during which expulsion of the conceptus (95%) often occurs. The patient is reexamined after 10-14 days. Complete abortion is observed in 95%, incomplete in about 2% of cases and about 1% do not respond at all. Oral mifepristone 200 mg (1 tab) with vaginal misoprostol 800 g (4 tabs, 200 g each) after 6-48 hours is equally effective. This combipack (1+4) is approved by DGHS, Government of India for MTP up to 63 days of pregnancy. Medical methods are safe, effective, noninvasive and have minimal or no complications.
