Brief summary
The primary goal of this study is to determine the clinical advantage of pre-treatment with mifepristone in second trimester misoprostol induction abortion. This will be a randomized controlled double-blinded trial of 20 women comparing misoprostol alone to mifepristone plus misoprostol for second trimester (14-21 weeks' LMP) medical abortion.
Interventions
single dose of 200 mg mifepristone followed 24 hours later by 400 mcg misoprostol administered buccally and repeated every 3 hours for a maximum of 5 doses.
DRUGPlacebo+Misoprostol
placebo resembling mifepristone followed 24 hours later by 400 mcg buccal misoprostol repeated every 3 hours until complete abortion or maximum of 5 doses.
