Formulation and In-Vitro Evaluation of Niosomal drug Delivery in Cancer Chemotherapy

Drug delivery systems are defined as formulations aim for transportation of a drug to the desired area of action within the body. The aim of the study was to investigate the feasibility of using Niosomes as a drug delivery system for Cisplatin By entrapment of drug in Niosomes, dose also could be reduced. Niosomes were prepared by Ethanol injection method using cholesterol and Surfactant. Particle size, zeta potential, entrapment efficiency and in vitro drug release studies were performed. The targeted niosome delivery system is composed of drug, surfactant and cholesterol. With regard to the influence of formulation variables on the percent drug loading (PDL), different compositions with varying ratios of surfactant and cholesterol were studied. In –Vitro drug release mechanism was studied for 24 hours.
