Organic solvent-free benznidazole nanosuspension as an approach to a novel pediatric formulation for Chagas disease
<b>Aim:</b> Benznidazole (BNZ), a class-II drug, is the primary treatment for Chagas disease, but its low aqueous solubility presents challenges in formulation and efficacy. Nanosuspensions (NS) could potentially address these issues.<b>Methods:</b> BNZ-NS were prepared using a simple, organic solvents-free nano-milling approach. Physicochemical characterizations were conducted on both NS and lyophilized solid-state BNZ-nanocrystals (NC).<b>Results:</b> BNZ-NS exhibited particle size <500 nm, an acceptable polydispersity index (0.23), high Z-potential, and physical stability for at least 90 days. BNZ-NC showed tenfold higher solubility than pure BNZ. Dissolution assays revealed rapid BNZ-NS dissolution. BNZ-NC demonstrated biocompatibility on an eukaryotic cell and enhanced BNZ efficacy against trypomastigotes of <i>Trypanosoma cruzi</i>.<b>Conclusion:</b> BNZ-NS offers a promising alternative, overcoming limitations associated with BNZ for optimized pharmacotherapy.
