Abstract
This study aimed to overcome the limitations of oral delivery and enhance the permeation of Captopril (CPL) by developing transferosomes. Transferosomes encapsulating CPL were prepared using a thin film hydration method. Seventeen formulations were prepared, varying Soya lecithin, Tween-20, and sonication speed. The formulations were evaluated for vesicle size (VS), polydispersity index (PDI), and entrapment efficiency (EE%). The optimized formulation’s discharge profile was compared with that of the CPL suspension. Transferosomes exhibited VS ranging from 244 to 376 nm and EE% from 65 to 91%, with zeta potentials ranging from -51 to -26 MV. In-vitro and ex-vivo permeation studies demonstrated superior drug permeation for transferosomal formulations compared to plain CPL suspension. CPL transferosomes represent a promising delivery system for prolonged and controlled drug discharge, offering potential improvements in hypertension management.
