ABSTRACT:
A two phase adhesive matrix for use in an electrically powered iontophoretic delivery device is provided. The adhesive matrix comprises an adhesive hydrophobic polymer phase and about 15 to 60 wt. % on a dry weight basis of a hydrophilic polymer phase distributed through the hydrophobic polymer phase. The hydrophilic phase forms upon hydration an interconnecting network of aqueous pathways for passage of the agent through the adhesive. The adhesive can be used to adhere an electrode assembly of an iontophoretic delivery device to a body surface such as skin or a mucosal membrane. Alternatively, the adhesive can be used to adhere together two or more elements of an iontophoretic delivery device.
