In the present study piroxicam loaded starch nanoparticles were prepared to enhance the solubility of piroxicam by nanoprecipitation technique. The preparation of nanoparticles was carried out as per central composite experimental design protocol, having concentration of starch and drug as independent variables and particle size and polydispersity index (PdI) as dependent variables. The particle size and PdI of piroxicam loaded starch nanoparticles was found to be between 282-870 nm and 0.339-0.772, respectively. After the characterization by FT-IR, TGA, XRD and SEM studies, the optimized batch was evaluated for in-vitro release study, anti-inflammatory activity and anti-oxidant activity. The in-vitro anti-inflammatory activity of piroxicam loaded starch nanoparticles was found to be more than the pure drug piroxicam whereas the anti-oxidant activity of starch is found greater than starch nanoparticles. Invitro release study showed 98.8% release in 2 h dissolution study following supercase II transport mechanism of drug release. (C) 2020 Published by Elsevier B.V. on behalf of King Saud University.
