| abstract |
A blend of at least two polymers in combination with a drug provides a pressure-sensitive adhesive composition for a transdermal drug delivery system in which the drug is delivered from the pressure-sensitive adhesive composition and through dermis when the pressure-sensitive adhesive composition is in contact with human skin. According to the invention, providing drug having differing crystal sizes as well as drug which is solublized in the pressure-sensitive adhesive composition controls the rate of drug delivery from the pressure-sensitive adhesive composition. |
