Abstract
An improved transdermal delivery system (TDS) comprises a self-adhesive matrix comprising a solid or semi-solid semi-permeable polymer which contains an amine-functional drug in its free base form as a multitude of microreservoirs within the matrix. The self-adhesive matrix is highly permeable to the free base of the amine-functional drug and is impermeable to the protonated form of the amine-functional drug.
