N2 - The release and permeation studies were carried out for developing transdermal therapeutic systems with chlorpheniramine maleate (CPM). The patches were prepared with Eudragit E100 with/without polyvinyl pyrrolidone (PVP) and dibutyl phthalate (DBP) as well as dibutyl sebacate (DBS) as the plasticizer in different compositions. Thickness, tensile strength, modulus of elasticity, 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 the increase of PVP & plasticizers but the tensile strength decreased. Experimental release/permeation data of different formulations of the matrix systems are reported. Also the drug-polymer interaction was investigated by ATR-FTIR studies. This study reports that the suitable plasticizer & chemical enhancers for Eudragit E 100 polymer for controlled release/permeation of CPM; hence this drug could be a potential candidate for transdermal antihistamine & wound healing applications in film device industry.
