Ethosomes as delivery system for transdermal administration of vinpocetine

Abstract

The purpose of the present study was to develop a novel transdermal vinpocetine patch containing a stable formulation and with good entrapment efficiency, and percutaneous absorption which via ethosome. Ethosome was found to be a more efficient delivery carrier with high encapsulation capacities (79.5% ± 1.8%) and nanometric size (180.7 ± 1.5 nm). In vitro percutaneous permeation experiments demonstrated that the permeation of vinpocetine through abdominal skin of Sprague Dawley was significantly increased when ethosome was used. The vinpocetine transdermal fluxes from ethosome gel (3.56 ± 0.13 μg/cm2/h) were 6.72 and 3.10 times higher than that of vinpocetine gel solution and vinpocetine aueous solution, respectively. Furthermore, the AUC0→∞, and eliminiation half-life by the transdermal administration were significantly higher than those by the intragastric administration (P < 0.01). The study demonstrated that ethosome is a promising vesicular carrier for enhancing percutaneous absorption of vinpocetine.
