Abstract
The aims of this study were to examine the phase behavior of itraconazole-phenol mixtures and assess the feasibility of topical formulations of itraconazole using eutectic mixture systems. Itraconazole-phenol eutectic mixtures were characterized using differential scanning calorimetry, Fourier transform infrared spectroscopy, 1H-nuclear magnetic resonance, and powder X-ray diffractometry. The skin permeation rates of itraconazole-phenol eutectic formulations were determined using Franz diffusion cells fitted with excised hairless mouse skins. Itraconazole can form eutectic compounds with phenol, and the hydrogen-bonding interactions between the carbonyl group in the itraconazole and hydroxyl group in phenol play a major role in itraconazole-phenol eutectic formation. Despite its high molecular weight and hydrophobicity, the drug (i.e.; itraconazole) can be permeated through excised hairless mouse skins from itraconazole-phenol eutectic formulations. The findings of this study emphasize the capabilities of the topical application of itraconazole via external preparations.
