Abstract

Glipizide is one of the most commonly prescribed drugs for treatment of type 2 diabetes.   Oral therapy with Glipizide comprises problems of bioavailability fluctuations and may be associated with severe hypoglycaemia and gastric disturbances. As a potential for convenient, safe and effective antidiabetic therapy, the rationale of this study is to develop a transdermal delivery system for Glipizide in order to improve its therapeutic efficacy.  In the preparation of films, chitosan was used as polymer. Inclusion complex of glipizide with β-Cyclodextrin was formed. The role of different permeation enhancers in the formulation was also studied. The films were characterized for thickness, tensile strength, drug content, moisture uptake, moisture content, and drug release. In vivo and skin irritation studies were performed for the optimized film.

 

Formulation F12 containing Chitosan (1.5percent w/v) and combination of permeation enhancers (Oleic acid: ethanol 1:1.5) showed the highest drug content 99.95percent and the drug release was 99.39percent in a period of 24 hours. The release data fitted into kinetic equations, yielded Higuchi plot and diffusion mechanism of drug release. The physical evaluation indicated the formation of smooth, flexible and translucent films. No skin irritation occurred on rat skin and the infrared studies showed the compatibility of the drug with the formulation excipients. The ex vivo study revealed a constant permeation of drug for long periods. The best permeation enhancer was F12 (Oleic acid: ethanol 1:1.5). The obtained results indicated the feasibility for transdermal delivery of Glipizide using Chitosan.
