BENZNIDAZOLE vs MEPRON
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benznidazole is a nitroimidazole derivative that exerts trypanocidal activity against Trypanosoma cruzi. Its mechanism involves the reduction of the nitro group by a nitroreductase enzyme in the parasite, leading to the generation of toxic metabolites that damage parasite DNA and other cellular components.
It is a hydroxynaphthoquinone that selectively inhibits mitochondrial electron transport chain in Plasmodium species, specifically at the cytochrome bc1 complex (Complex III), leading to collapse of mitochondrial membrane potential and inhibition of pyrimidine synthesis.
5-7 mg/kg/day orally divided into two daily doses for 60 days. Maximum daily dose: 300 mg.
750 mg orally twice daily with food for 21 days for treatment of mild-to-moderate Pneumocystis jirovecii pneumonia. For prophylaxis: 1500 mg orally once daily with food.

Terminal elimination half-life is approximately 12 hours; may be prolonged in hepatic impairment.
Mean terminal elimination half-life is 2.2-3.2 days (approximately 53-77 hours) in adults; prolonged in hepatic impairment (up to 22 days) and in elderly (up to 5 days).
Primarily renal excretion of metabolites; <5% unchanged drug. Approximately 20% in feces.
Primarily fecal (87-94%) via bile; renal excretion accounts for <1% as unchanged drug. A minor metabolite, atovaquone glucuronide, is excreted in urine.
