Abstract

The aim of the present investigation was to design a mucoadhesive liposomes containing Prednisone. Liposomes were prepared by the thin film hydration method by using chloroform as a solvent. Mucoadhesive liposomes containing prednisone formulations were prepared by different concentration of lecithin and cholesterol by thin film hydration technique. These formulations were evaluated for entrapment efficiency, particle size, zeta potential, surface morphology and in-vitro drug release. Particle size and zeta potential of the F4 formulation was found to be 212 nm, -164.9 mV respectively. Coating of liposomes resulted increase in particle size and also increases the zeta potential. Highest entrapment efficiency was observed in F1 and F3 92% and 94%. The percent drug release from F1-F4and CF1 was observed as follows F1- 88.57%, F2-73.31%, F3-76.29%, F4-90.97%, and F1 coated as a CF1-69.85%. Release kinetics follows the Higuchi plot and non-Fickian diffusion mechanism.

Keywords: Predisone, mucoadhesive liposome, thin film hydration method, in-vitro release.
