The present release and permeation studies were carried out for developing transdermal therapeutic systems with chlorpheniramine maleate (CPM). The matrix patches were prepared from ethyl cellulose (EC) with polyvinyl pyrrolidone (PVP) as the copolymer and plasticizers like dibutyl phthalate (DBP), dibutyl sebacate (DBS), triethyl citrate (TEC), acetyl triethyl citrate (ATEC), tributyl citrate (TBC) and acetyl tributyl citrate (ATBC) in different percentages. Thickness, tensile strength, elasticity, drug content, moisture content and water absorption studies of the matrix patches were measured. In vitro release/permeation of CPM was studied in a modified Keshary - Chien diffusion cell. Experimental release/permeation data (percent release and flux, μgm/cm2 .hr) of different formulations of the matrix systems are reported. Also the drug-polymer interaction was investigated by ATR-FTIR studies. This study reports the effect of CPM in EC patch and suitable amount of plasticizer for better controlled release/permeation of CPM; hence this drug could be a potential candidate for transdermal antihistamine applications in film device industry.
