What is Benznidazole?[edit | edit source]

Benznidazole a nitroimidazole antimicrobial, is indicated in pediatric patients 2 to 12 years of age for the treatment of Chagas disease.

Benznidazole is used in pediatric patients 2 to 12 years of age for the treatment of Chagas disease.

Benznidazole is a nitroimidazole antimicrobial drug.
Benznidazole inhibits the synthesis of DNA, RNA, and proteins within the T. cruzi parasite.
Studies suggest that benznidazole is reduced by a Type I nitroreductase (NTR) enzyme of T. cruzi producing a series of short-lived intermediates that may promote damage to several macromolecules including DNA.
In mammalian cells, however, benznidazole is metabolized by reduction of the nitro group to an amino group by a Type II NTR enzyme. The precise mechanism of action is not known.

This medicine cannot be used in patients with:

a history of hypersensitivity reaction to benznidazole or other nitroimidazole derivatives.
who have taken disulfiram within the last two weeks. Psychotic reactions may occur in patients who are using benznidazole and disulfiram concurrently.
