OBJECTIVE: To compare the efficacy and safety of clindamycin vaginal ovules with oral metronidazole for treatment of bacterial vaginosis.
METHODS: Women with bacterial vaginosis received either 100-mg ovules of clindamycin (intravaginally for 3 consecutive days) plus placebo capsules (orally twice daily for 7 days) or metronidazole 500 mg (two 250-mg capsules orally twice daily for 7 days) plus placebo ovules (intravaginally for 3 consecutive days). The sample was determined prospectively to provide a probability of.84 of correctly concluding that the rate of success for clindamycin is not more than 15% less than the expected 75% success rate for metronidazole. Clinical outcome was determined on the basis of vaginal fluid amine odor and clue cells.
RESULTS: Of the 399 patients enrolled, 233 could be evaluated for efficacy. Of those, 77 (68.1%) of 113 patients were cured with clindamycin, compared with 80 (66. 7%) of 120 who were cured with metronidazole (95% confidence interval -10.6%, 13.4%; P =.810). Treatment-related adverse events were reported more frequently in the metronidazole treatment group. Systemic symptoms, such as nausea and taste perversion, accounted for most of the difference between groups.
CONCLUSION: A 3-day regimen of clindamycin, given as intravaginal ovules, was as effective as and better tolerated than a 7-day regimen of oral metronidazole 500 mg, given twice daily, for treatment of bacterial vaginosis.
