Skin permeation of econazole nitrate formulated in an enhanced hydrophilic multiple emulsion.
Mycoses 2017 March
Local delivery of imidazolic antifungals is limited by its extreme lipophilicity. Multiple emulsions (ME) are a potential vehicle to enhance the delivery of econazole nitrate (ECN), an antifungal targeted to deep-seated epidermal yeast infections. An 1% ECN hydrophilic ME was compared with a commercial formulation in terms of rheology, droplet size and in vitro antifungal activity against Candida species. Comparative in vitro drug release, human skin permeation and drug retention were investigated using vertical diffusion cells. Rheology demonstrated a pseudoplastic shear thinning with thixotropy facilitating skin residence. No significant aggregation or droplet size variations were observed during a 6-month stability storage. Both formulations exhibited similar release levels achieving asymptotic values in 5 h. ECN skin permeation levels from the multiple emulsion resulted to be significantly higher than those of the commercial formulation, attributable to differences in formulation polarity and excipients composition. Conversely, similar drug accumulation levels in skin were obtained (40-130 ppm). These concentrations resulted to be comparable with obtained MIC values (2-78 ppm), confirming the in vitro antimicrobial efficacy of both formulations. A similar skin retention and a higher permeation rate over the existing formulations is considered an improved approach to target the drug to deep epidermis.
