Itraconazole (ITR), an antifungal agent has poor bioavailability due to low aqueous solubility. The present investigation aimed at development of ITR nanoemulsion to enhance its oral bioavailability. ITR nanoemulsion was prepared using Capmul MCM C8 as oil, Pluronic F68 as co-surfactant and Cremophore EL as surfactant using high speed stirring, followed by probe sonication. Nanoemulsion with average globule size of 100.9 nm and zeta potential of -35.9 ± 1.2 mV was able to penetrate well into the intestinal membrane as confirmed by the laser confocal scanning microscopy and ex vivo intestinal permeability study. Antimycotic study confirmed the efficacy of ITR nanoemulsion. Significantly higher values of pharmacokinetic parameters the formulation than the plain drug and marketed formulation indicated an increase in the bioavailability of ITR. The prepared nanoemulsion was stable at both, refrigerated and room temperature conditions. Nanoemulsion of ITR seems to be a promising formulation for enhancement of its oral bioavailability. © 2015 Taylor & Francis. Source
