Misoprostol only for abortion: Viable option but not 'the best'.

The article reports that misoprostol-only regimen for medical abortions is safe but not as effective as the combination of mifepristone and misoprostol. It mentions that in the two-drug regimen to terminate a pregnancy, patients first take the progesterone blocker mifepristone to end the pregnancy and then misoprostol, which causes the uterus to expel the pregnancy tissue. It presents the views of Beverly Gray, associate professor in department of obstetrics and Gynecology at Duke University.
