The current study was undertaken to develop solid lipid nanoparticles (SLN) of a hydrophilic drug Penciclovir and improve the entrapment efficiency of the drug in SLN. The SLN were prepared with Precirol ATO 5 as lipid using solvent-evaporation technique by Box Behnken design. Three operating variables lipid concentration, Surfactant and Sonication time were found to have significant effect on the particle size, entrapment efficiency (EE) and zeta potential of the SLN. The maximum EE was found to be 87.43% with particle size of 167.3nm and zeta potential of -22.77. The optimized batch was also analyzed for its morphological, physiochemical and ex vivo intestinal permeation properties. This work indicates that Penciclovir loaded in SLN could be better option for enhancing the permeability of Penciclovir in intestine as compared to existing marketed formulations.
