Abstract
Chagas disease, caused by Trypanosoma cruzi (T. cruzi), affects millions worldwide, particularly in Latin America. Despite its prevalence, treatment options remain limited. Current drugs, such as benznidazole, cause adverse effects possibly due to ineffective administration. In this context, nanoparticles offer a promising solution to target and control drug delivery by leading the effector site and minimizing side effects. This article focuses on zein-casein-based nanoparticles (Bioparticles, BP) coated with Eudragit L100-55 (BP:EU) for enteric delivery of benznidazole. BP:EU structures are synthesized to minimize premature drug release in the stomach, promoting release in the small intestine. Physical characterization confirmed the successful synthesis of BP:EU and their pH-responsive trigger for drug release. These findings suggest that this material can be a promising approach for Chagas disease treatment, addressing challenges in benznidazole delivery that can lead to improved therapeutic responses.
