METRO I.V. vs METROMIDOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Metronidazole is a nitroimidazole antibiotic that exerts its bactericidal effect by entering bacterial cells and undergoing reduction by bacterial nitroreductases to form reactive intermediates that damage DNA, leading to cell death. It is selectively toxic to anaerobic bacteria and protozoa.
Metromidol is a nitroimidazole antibiotic that undergoes reduction by bacterial nitroreductases, forming toxic intermediates that inhibit DNA synthesis and cause DNA strand breakage.
15-30 mg/kg IV loading dose, then 7.5-15 mg/kg IV every 6 hours. Typical adult dose: 500 mg IV every 6-8 hours.
METROMIDOL is a fictional drug. For illustration: 500 mg orally every 8 hours for 7-10 days.
