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.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Rate of successful abortion: defined as complete evacuation of uterus using study drug without recourse to any additional intervention. [ Time Frame: every 3 hours ]
  2. Induction-to-abortion interval: defined as time elapsed between administration of the first misoprostol dose until expulsion of the fetus; approximately 10-24 hours. [ Time Frame: 48 hours ]

Secondary Outcome Measures :
  1. Provision of additional interventions to manage excessive blood loss. [ Time Frame: Within 30 days of mifepristone administration. ]
  2. Total dose of misoprostol. [ Time Frame: Assessed at time of complete abortion with study drug alone or when total maximum dose given: approximately 10-24 hours after first dose of misoprostol administration. ]
  3. Any heavy bleeding, uterine rupture, or infection requiring additional treatment [ Time Frame: Within 30 days of mifepristone administration. ]
  4. Pain experienced by the woman [ Time Frame: Assessed during exit interview: approximately 48 hours after first dose of misoprostol administration. ]
  5. Women's acceptability of the assigned method [ Time Frame: Assessed during exit interview: approximately 48 hours after first dose of misoprostol administration. ]
