  RESULTS
  At 1 week, the cure rate of tinidazole and ornidazole was 100% and at 4 weeks, it was 97.7% for both drugs (P<0.001). Secnidazole had cure rate of 80.2% at 4 weeks (P=NS). Metronidazole showed a cure rate of 77.9% at 4 weeks, which is the lowest of all four drugs.

  Tinidazole and ornidazole have better cure rate as compared to metronidazole in cases of bacterial vaginosis.
