METRONIDAZOLE vs VANDAZOLE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
After entry into the cell, metronidazole is reduced by bacterial nitroreductases to form toxic metabolites that damage DNA and inhibit nucleic acid synthesis, leading to cell death.
VANDAZOLE is a nitroimidazole antimicrobial agent that undergoes reduction by bacterial nitroreductases, forming cytotoxic free radicals that damage DNA and inhibit nucleic acid synthesis.
500 mg intravenously every 8 hours or 500 mg orally every 8 hours; for bacterial vaginosis, 500 mg orally twice daily for 7 days; for trichomoniasis, 2 g orally as a single dose.
2 g orally as a single dose once daily for 2 days.
