Abstract
A solid state, resilient laminated composite for administering a drug transdermally consisting of a multiplicity of spaced structural laminas of a resilient elastomer, one of which forms the top of the composite, a viscoelastic hydrophobic polymer lamina containing propylene glycol monolaurate interposed between each structural lamina and a pressure-sensitive adhesive lamina that provides the basal surface of the composite and consists of a blend of a pressure-sensitive adhesive, drug and propylene glycol monolaurate.
