A prospective randomized, double-blinded, placebo-controlled trial comparing mifepristone and vaginal misoprostol to vaginal misoprostol alone for elective termination of early pregnancy

Abstract

A regimen of mifepristone and misoprostol was significantly more effective for termination of pregnancies < or = 56 days than misoprostol alone. The 88% efficacy obtained with vaginal misoprostol alone may be clinically acceptable when mifepristone is not available.
