Effect of components (polymer, plasticizer and solvent) as a variable in fabrication of diclofenac transdermal patch.
Transdermal drug delivery influence consumer acceptance and marked increase in bioavailability of some drugs which undergoes hepatic first-pass metabolism. Fabrication of transdermal patch requires lots of attention regarding the amount of components used for it. Because of varied nature of polymer and plasticizer, transdermal patches have different properties and different drug release. This study is on the basis to evaluate the amount to be needed for fabrication of diclofenac transdermal patch. Study shows that Hydroxy Propyl Methyl Cellulose has great influence on transdermal patch, if it is used alone in combination with glycerin or PEG-4000 plasticizer.
