GLIBENCLAMIDE TRANSETHOSOME PATCH FOR TRANSDERMAL DELIVERY: FORMULATION AND EVALUATIONS

Abstract

Objective: The glibenclamide transethosome patch is a patch containing glibenclamide encapsulated in nanoparticle-based vesicles that can improve the penetration of the compound into the skin. The research work aims to evaluate glibenclamide transethosome patches using HPMC and PVP as matrix polymers and glibenclamide as a drug model. Methods: Glibenclamide transethosome patches were prepared using a solvent evaporation technique. Evaluations that have been carried out to assess the stability of the patch include weight variation, folding endurance, thickness, moisture absorption, moisture content, drug content, and drug release in vitro glibenclamide transethosome was carried out using Franz diffusion cell. Results: The results of the evaluation of the glibenclamide transethosome patch showed a patch weight uniformity between 0.051-0.063 g and a CV (Coefficient of Variation) value of less than 5%. The resulting folding resistance of the patch can withstand without tearing over 200 folds. The thickness of the glibenclamide transethosome patch is between 0.14-0.24 cm. The moisture absorption capacity of the patch is between 2.1-23.5%. The moisture content of the patch is between 4.7-7.4%. The drug content of the patch is between 6.7–12.7 g/cm2. Drug release from the patch was between 45.9-82.1% after 480 min. Overall, in the moisture absorption test (F3; F4; F5), moisture content, drug content, and drug release (F1) gave significantly different results (p<0.05). Conclusion: The glibenclamide transethosome patch showed evaluation results that met the requirements and were stable during the stability test. The polymer combinations also significantly influence drug release during stability tests.
