ABSTRACT:
A silicone pressure sensitive adhesive composition which is compatible with drugs, excipients, co-solvents and skin penetration enhancers is disclosed which includes a cohesive strengthening agent in combination with a silicone fluid and a silicate resin. The addition of the cohesive strengthening agent helps to maintain the adhesive on the substrate, while reducing cold flow. The adhesive is useful as an improved component in transdermal drug delivery devices and related medical devices.
