Chagas disease is a public health problem, affecting about 7 million
people worldwide. Benznidazole (BZN) is the main treatment option, but
it has limited effectiveness and can cause severe adverse effects. Drug
delivery through nanoparticles has attracted the interest of the
scientific community aiming to improve therapeutic options. The aim of
this study was to evaluate the cytotoxicity of benznidazole-loaded calcium carbonate nanoparticles (BZN@CaCO3) on Trypanosoma cruzi strain Y. It was observed that BZN@CaCO3 was able to reduce the viability of
epimastigote, trypomastigote and amastigote forms of T. cruzi with
greater potency when compared with BZN. The amount of BZN necessary to
obtain the same effect was up to 25 times smaller when loaded with CaCO3 nanoparticles. Also, it was observed that BZN@CaCO3 enhanced the
selectivity index. Furthermore, the cell-death mechanism induced by both BZN and BZN@CaCO3 was evaluated, indicating that both substances caused
necrosis and changed mitochondrial membrane potential.
