Misoprostol tablets moistened with 3 ml of 5% acetic acid were placed into the posterior vaginal fornix. Results The median induction-abortion times in groups A (8 h [range: 3-64]) and B (9 h [4-81]) were significantly shorter (p < 0.01 and p < 0.05, respectively) than in group C (12.5 [3-72]). Moreover, expulsion rates within 24 hours in groups A (92.3%) and B (92.3%) were significantly higher (p < 0.05 in both cases) than that of group C (75%). Expulsion rate within 48 hours, number of tablets used, number of patients with retained placenta and side effects did not differ between groups. Conclusions Misoprostol moistened with acetic acid is effective for second-trimester pregnancy termination when given vaginally 3-hourly, 6-hourly or 12-hourly. The former two regimens are significantly more effective than the latter.en10.3109/13625180903417486info:eu-repo/semantics/closedAccess2nd Trimester PregnancyIntravaginal MisoprostolMedical AbortionMifepristoneSalineTrialArticle1515459Q2WOS:0002748563000092-s2.0-7724908762920063994Q2
