Objective: We aimed to determine whether second-trimester abortion using isosorbide mononitrate (IMN) in addition to gemeprost is more effective and reduces side effects compared with gerneprost alone. Study design: Eighty women who were age 13 to 23 weeks´ gestation were randomly assigned to receive per vaginam either IMN 40 mg (group 1, 40 women) or placebo (group 2, 40 women) in addition to Gemeprost I mg up to 3 times daily 3 hours apart for 2 days. Analysis of variance, a chi 2 test, and a multivariate analysis were performed. Results: Of the 72 women analyzed, 68% (group 1) and 38% (group 2) underwent abortion within day 1 (P < .05). However, group 1 was associated with more headache (18% of women) 3 hours after induction compared to group 2 (0% of women, P = .038). Conclusion: IMN in addition to gemeprost is effective for second-trimester abortion, but is associated with more headache compared with gemeprost alone.
