Preparation and Evaluation of Ketoprofen Loaded Mucoadhesive Microspheres

The aim of the present study was to prepare and evaluate Ketoprofen loaded microspheres fabricated with sodium alginate and Carbopol 934 by ion gelation method which enhances the drug residence time into the stomach by adhering to the mucus layer of and control the rate of drug release for longer period of time. Ketoprofen is a nonsteroidal anti-inflammatory drug (NSAID) that is commonly used for its analgesic, anti-inflammatory, and antipyretic (fever-reducing) properties. It belongs to the propionic acid class of NSAIDs and is available in various formulations, including oral tablets, capsules, topical gels, creams, and as an injectable solution. In present study ketoprofen incorporates in mucoadhesive drug delivery system for utilizing its controlled drug delivery up to 12 hrs. In present study prepared microspheres were evaluated for- particle size, entrapment efficiency, percentage yield, morphology, mucoadhesive property, in-vitro drug release property.
