Simultaneous administration of mifepristone and misoprostol for early termination of pregnancy: a randomized controlled trial.

AIM: To compare the efficacy of different intervals of misoprostol administration (simultaneously vis-à-vis 24 h), after mifepristone, in women undergoing medical termination of pregnancy up to gestation of 49 days. METHODS: Eighty eligible women with single intrauterine pregnancy of ≤ 7 weeks of gestation requesting abortion were randomized to receive either 200 mg of mifepristone orally and 400 µg of misoprostol vaginally simultaneously (Group 1) or at 24-h interval (Group 2).Women who had no bleeding after the drugs were offered a second dose of misoprostol 24 h after the first dose. All patients were followed up on day 14. Primary outcome measure was the complete abortion rate. Secondary outcome measures were the induction-abortion interval, adverse effects, especially bleeding, and treatment acceptability rate. Treatment was considered a failure if surgical intervention was needed for any indication. RESULTS: Complete abortion was achieved in 38 women [95%; 95% confidence interval (CI) 88%, 100%] in Group 1 and 39 women (97.50%; 95% CI 93%,100%) in Group 2 (p = 0.56). A second dose of misoprostol was needed in two patients in Group 1 and in only one patient in Group 2. The induction-abortion interval was 6.50 ± 1.48 h in Group 1 and 5.95 ± 1.81 h in Group 2 (p = 0.13). The difference in frequency of adverse effects in the two groups was statistically insignificant (p = 0.18). The treatment acceptability rate was 97.50% in Group 1 and 95% in Group 2 (p = 0.56). CONCLUSION: Simultaneous administration of mifepristone and 400 µg vaginal misoprostol is an effective alternative to standard regimens for medical abortion up to 49 days of gestation.

Is mifepristone 100mg an effective alternative to standard dose for medical abortion.

OBJECTIVE: To study the efficacy of a low dose of mifepristone (100 mg) in combination with misoprostol, in women undergoing medical termination of pregnancy up to gestation of 49 days. MATERIAL AND METHODS: A prospective study was performed in 50 women (mean age 26.54±3.68 years) with single intrauterine pregnancy of up to 49 days of gestation, presenting to our institution between November 2007 and October 2009. 100 mg mifepristone was given orally, followed 24 hours later by 400 micrograms misoprostol vaginally. Misoprostol 400 micrograms was repeated vaginally on the third day if indicated. The primary outcome of complete abortion rate and secondary outcomes of induction-abortion interval and adverse effects, especially bleeding, were assessed. RESULTS: Mean period of gestation was 38.74±3.90 days. None of the women expelled the products of conception before misoprostol insertion. A second dose of misoprostol was needed in four patients. Complete abortion was achieved in 94.00% of patients, incomplete abortion in 4% and missed abortion in 2%. Approximately all the women reported one or more adverse effects but none of them had any serious ones, the most common being pain in 42 (84%) women followed by nausea, vomiting, fever and diarrhoea in 12 (24%), 6 (12%), 4 (8%) and 3 (6%) women respectively. The overall acceptability rate of the dosing regimen in our study was 94%. CONCLUSION: A regimen of low dose mifepristone (100 mg) followed 24 hours later by vaginal misoprostol can be safely and effectively used for early abortion.
