Development and Optimization of Solid Lipid Nanoparticle for Topical Delivery
The aim of present work was to develop and evaluate solid lipid nanoparticle (SLNs) based gel for topical delivery of anti-inflammatory drug. Material and method Nabumetone loaded SLNs were developed by hot homogenization followed by ultra- sonication technique using compritol 888 ATO as solid lipid and tween 80 as a surfactant. Developed SLNs were evaluated for particle size, entrapment efficiency (EE) and drug release profile. Process and formulation parameters were optimized. Differential scanning calorimetry (DSC) and X-ray diffraction (XRD) studies were carried out on SLNs to mark the change in the drug and lipid modification. The Nabumetone based gels were prepared using carbopol 940 as gelling agent. Results and conclusion: The F14 batch had shown maximum entrapment efficiency up to 94.40 and sustained drug release for more than 7 hours. The particle size of optimized batch (F14) was found to be 16.54. Keywords: Solid lipid nanoparticle, Entrapment efficiency, Colloidal carrier.
