The aim of the present study was to formulate topical microspheres based delivery system containing Clindamycin for treatment of infections. The microsphere was prepared by double emulsion solvent diffusion method. Then after the optimized batches incorporated into gel base. Clindamycin phosphate is lincosamide antibiotic and is used mainly for treatment of acne. The microspheres of the optimum batch (N5) exhibited 79.1% drug entrapment efficiency, mean particle size of 310 µm and 94.96% release at 8 hour. An appropriate balance between the levels of the polymer (EC) and stirring speed was imperative to acquire maximum drug entrapment efficiency, control release of the drug, and adequate particle size. The optimize batch was further used for antimicrobial study and skin irritation study and also compared with marketed gel clindawel. Antimicrobial study was performed on nutrient agar media for S.epidermidis and agar media for P. acne because of both of microbes responsible for production of acne. The zone of inhibition of formulated gel against S.epidermidis and P.acne microbes was greater than marketed gel.
