Abstrakt: Aim: The aim of this study is to prepare and characterize simvastatin-loaded nanoemulsions (SIM-LN) as well as evaluate their physicochemical properties and toxicity. Methodology & results: The SIM-LN were prepared, their characteristics evaluated for 30 days, and after that, the SIM-LN toxicity was evaluated using Vero cell culture and the in vivo model of Caenorhabditis elegans . The prepared SIM-LN had an average droplet size of 139 ± 22 nm, with high encapsulation rate (>98.4%). The storage at room temperature proved to be the most optimal condition. Toxicity assays demonstrated no toxicity. Conclusion: It was demonstrated that the surfactants used as emulsifiers optimized the properties without side effects, because no toxicity was measured in preliminary tests.
