The aim of this study was to prepare nimesulide solid lipid nanoparticles (NIM-SLNs), to formulate the controlled drug release and to evaluate its physiochemical characteristics. NIM-SLNs were prepared by an emulsification and low-temperature solidification method. Additionally, attempts have been made to study the effect of individual process parameters (stirring speed and stirring time) and formulation parameters (Lecithin concentration, drug concentration and surfactant concentration) on entrapment efficiency. An approximately entrapment efficiency of (60%) and an average drug loading of (1.0 %) were achieved from optimized formulation of NIM-SLNs. The results show that the TMZ-SLNs had an average diameter of 187±1.23nm and in vitro drug release was conducted in phosphate-buffered saline (pH 7.4) at 37o C. The cumulative percentages drug release of nimesulide was found approximately 60% in 24 hours and release behavior was in accordance with Higuchi-equation. The results indicate that the SLNs is a promising controlled-release system. It may also allow a reduction in dosage and a decrease in systemic toxicity.
