In Vivo Benznidazole (100 mg/kg/day, p.o., 30 days) produces a decrease in electrocardiographic alterations, fewer modifications in the affinity and density of cardiac-receptors, and few isolated areas of fibrosis in the heart, in mice infected with Trypanosoma cruzi Tulahuen strain or SGO-Z12 isolate and treated at 180 days post infection (p.i.) (i.e. chronic phase) with Benznidazole[1]. Animal Model: Mice infected with Trypanosoma cruzi Tulahuen strain or SGO-Z12[1] Dosage: 100 mg/kg/day Administration: Orally for 30 days Result: Produced a decrease in electrocardiographic alterations, fewer modifications in the affinity and density of cardiac-receptors, and few isolated areas of fibrosis in the heart.
