DOI : 10.29228/jrp.28 The aim of this study is to develop PLGA based nanoparticle drug delivery systems loaded with nimesulide which is a non-steroidal anti-inflammatory (NSAI) agent and a selective COX-2 inhibitor that proved its antineoplastic and antitumor activity on cancer carsinogenesis and chemotherapy via epidemiological, pathological, clinical and biological studies in the last years, and modify their surface properties using chitosan chloride. For this purpose, Nimesulide loaded PLGA nanoparticles modified with chitosan chloride were developed with solvent evaporation-diffusion-salting out method. Nanoparticle formulations were evaluated for production yield, process efficacy, particle size and polydispersity index (PDI), surface charge, morphologic properties, redispersibility index, residual PVA amount and in vitro dissolution rate profiles. The results obtained showed that surface modification with chitosan chloride was significantly effective statistically on the final properties of the nanoparticles. With this study, it was shown that PVA and chitosan chloride combined can play a key role in developing cationic and positively charged nanoparticles.
