Formulating it as niosomal formulation might be quite advantageous for prolonging the duration of pharmacological action and improved bioavailability.</p><p><strong>Methods: </strong>In the present study niosomal formulations were prepared by using most documented thin film hydration technique by using various grades of surfactants (span 20, 40, 60, 80) in varying ratios with cholesterol, negative charge inducer di cetyl phosphate (DCP) and drug famotidine. Suitable preformulation studies were conducted like identification of drug, excipient and drug compatibility study. The optimized drug loaded niosomes were characterized for size and morphology, polydispersity index, zeta potential, drug entrapment, <em>in vitro</em> release, <em>in vivo</em> study and stability study.</p><p><strong>Results: </strong>The results showed that the vesicles formed were spherical in shape, size ranging between 160.1 nm to 718.7 nm with zeta potential values indicating good stability and formulation containing span 60 (NMS7) showed the highest entrapment efficiency (73.234%). All the formulations showed prolonged release profile for more than 24 h with release kinetics better suited to zero order release pattern. <em>In vivo</em> study conducted on rabbits predicted a fourfold increase in pharmacokinetic parameter (area under curve)AUC and pharmacological action for more than 24 h as compared to free drug famotidine which showed its action only upto 12 h.</p><p><strong>Conclusion: </strong>Thus the famotidine loaded niosomal formulation may be considered as a very promising drug delivery system which could be successfully employed for prolonging the drug release and overcoming the drawbacks of conventional drug delivery systems.</p> ER -
