The purpose of this study was to prepare and characterize a hybrid system of moxifloxacin loaded niosomes incorporated into chitosan gel as a potential carrier for topical antimicrobial delivery. The prepared system was characterized regarding entrapment efficiency, particle size, zeta potential, in vitro drug release kinetics, morphology, FTIR analysis, bioadhesive strength and rheological behavior. The effect of different formulation parameters (surfactant type, surfactant to drug ratio, cholesterol percentage and loading methodology) on moxifloxacin entrapment and drug release was evaluated. The antibacterial effectiveness of various formulations was also assessed by measuring the minimal inhibitory concentrations, minimal bactericidal concentrations and agar diffusion assay using Pseudomonas aeruginosa and Staphylococcus aureus as model pathogens. The optimized niosomal formulation showed 73 …
