Design and in vitro evaluation of chlorpheniramine maleate from different eudragit based matrix patches: Effect of platicizer and chemical enhancers.

Abstract

The release and permeation studies were carried out for developing transdermal therapeutic systems with chlorpheniramine maleate (CPM). The patches were prepared with eudragit RS-100 and RL-100 with/without polyvinyl pyrrolidone (PVP) and dibutyl phthalate (DBP) in different compositions. Thickness, tensile strength, drug content, moisture content and water absorption studies of the patches were measured. In vitro release/permeation of CPM was studied in modified Keshary-Chien diffusion cell. Chemical enhancers like l-menthol, oleic acid and phospholipon80 were added to compare the release pattern of the drug. The percent release of the drug from matrix patch increased with increase of PVP & DBP but the tensile strength decreased with the increase of DBP & PVP. Experimental release/permeation data of different formulations of the matrix systems are reported. Also the drug-polymer interaction was investigated by ATR-FTIR studies. The discussion was correlated the efficient matrix dispersion patch from suitable eudragit polymers for transdermal antihistamine applications in film device industry.
