The main objective of the present investigation was to develop gastro retentive (floating) microsphere for Cefdinir. Cefdinir, Third-generation bactericidal cephalosporin antibiotic drugs has been chosen as a model drug in the formulation of floating drug delivery systems. It is a drug of choice in treatment of otitis media, soft tissue infections, and respiratory tract infections, including sinusitis, strep throat, community-acquired pneumonia and acute exacerbations of bronchitis. Three biocompatible polymers like HPMC, Ethyl cellulose and Eudragit were chosen in varying proportions with the drug. F5 formulation with drug: polymer (1:2) show excellent micromeritic properties, percent yield (87.22%), drug entrapment efficiency (92%), percent buoyancy (89%), and highest invitro drug release 98.9% within 12 h. In the stability studies no significant change in drug entrapment release characteristics of the microspheres.
