Background

Benznidazole is an orally bioavailable antiprotozoal agent.¹ It is a 2-nitroimidazole prodrug that becomes active when the nitro group is reduced within the parasite.² It inhibits the growth of the parasites T. cruzi, T. vaginalis, G. lamblia, and E. histolytica (IC₅₀s = 8.1, 18.62, 22.58, and 4.27 μM, respectively).^3,4 It also inhibits clonogenic growth of human C33A cervical and KNS42 glioblastoma cancer cells under hypoxic, but not normoxic, conditions when used at a concentration of 100 μM.⁵ Benznidazole (100 mg/kg per day) decreases T. cruzi blood parasitemia to below detectable levels in a mouse model of chronic stable Chagas disease.¹ Formulations containing benznidazole have been used in the treatment of Chagas disease caused by T. cruzi.
