Abstract
The aim of present study was to construct and investigate the efficacy of solid lipid nanoparticles (SLNs) based hydrogel for transdermal delivery of non-steroidal anti-inflammatory drug (NSAID) piroxicam. Solid lipid nanoparticles (SLNs) of piroxicam were produced by solvent emulsification diffusion method in a solvent saturated system. The SLNs were composed of tripalmitin lipid, polyvinyl alcohol (PVA) as stabilizer, and solvent ethyl acetate. All the formulations were subjected to particle size analysis, zeta potential, drug entrapment efficiency, percent drug loading determination and in-vitro release studies. The SLNs formed were in nano-size range with maximum entrapment efficiency of 88.50±0.92. Further, Carbopol-934 was used as a gel matrix for preparation of hydrogel for improving the penetration rate across the skin and viscosity of piroxicam loaded SLNs for transdermal drug administration. The drug release behaviors from piroxicam loaded SLNs based hydrogel exhibited long duration and constant rate of drug release over 24 hr. Skin penetration of piroxicam loaded SLNs based hydrogel was assessed by confocal laser scanning microscopy (CLSM).
