Fungal infection is one of the common dermatological diseases. Drug delivery systems for topical use have shown significant advantages in targeting the drug to the action site in the body and also reduces the systemic side effects. Itraconazole was chosen as a model drug with low aqueous solubility. In the present study an attempt was made to prepare itraconazole loaded nanostructured lipid carrier (NLC). Different formulations were prepared by hot homogenization technique using solid lipid and liquid lipid (Compritol 888 & Caprol PGE 860) and surfactants (Poloxamer 188, tween 80). All the Formulations were characterized for drug content, entrapment efficiency, particle size, poly dispersity index, zeta potential &in vitro drug release and FTIR was done to study any interaction between excipients. The best formulation shows better drug release and entrapment efficiency 83.2%. the best formulation F3 showed better in-vitro drug release 55.46% at the end of 8th hour. The F3 was made into gel using Carbopol as a gelling agent. SEM study revealed that the NLC gel shows the particle size was found to be 500 nm in size smooth surfaces. NLC gel shows Drug release of NLC gel followed non- Fickian diffusion. NLC gel were stable at 40 ± 2ֹ°C and 75 ± 5% RH. Thus, the prepared NLC gel proved to be a potential candidate as a topical nanoparticulate sustained drug delivery system for itraconazole (BCS class II drug). keywords: Itraconazole, Nanoparticle Lipid Carrier, Lipids.
