Abstract

Rosuvastatin (ROS), a statin drug with promising anticancer properties has a low bioavailability of approximately 20% due to lipophilicity and first-pass metabolism. This study aimed to enhance ROS anticancer efficacy through loading into flexible chitosomes. The chitosomes were prepared starting from negatively charged liposomes through electrostatic interactions with chitosan. The conversion of zeta potential from negative to positive confirmed the successful formation of chitosomes. The chitosan coating increased the particle size and zeta potential, which ranged from 202.0 ± 1.7 nm to 504.7 ± 25.0 nm and from - 44.9 ± 3.0 mV to 50.1 ± 2.6 mV, respectively. Chitosan and drug concentrations had an important influence on the chitosome properties. The optimum chitosome formulation was used to prepare ROS-loaded flexible chitosomes using different concentrations of four edge activators. The type and concentration of edge activator influenced the particle size, drug entrapment efficiency, and drug release rate of the flexible chitosomes. Flexible chitosomes significantly increased drug permeation through rat abdominal skin compared to control transferosomes and drug solution. The optimal ROS flexible chitosomes containing sodium deoxycholate as an edge activator had a 2.23-fold increase in ROS cytotoxic efficacy against MCF7 cells and a 1.84-fold increase against HepG2 cells. These results underscore the potential of flexible chitosomes for enhancing ROS anticancer efficacy.
