The system comprises a laminate composite of a patch/skin permeable membrane; a transfer gel layer disposed on said permeable membrane; a permeable membrane disposed on said transfer gel layer; a plurality of sectional drug reservoirs for receiving medicament disposed on the transfer gel layer; and activation means for releasing medicament from said drug reservoirs for contact with skin of a patient. The medicament in contained in the reservoirs at varying amounts and/or concentrations, providing for selectable dosage, for sequential delivery, for sequential activation, for variable unit dose drug delivery in transdermal application.Field of SearchTransdermal or percutaneousPressure sensitive adhesive means BANDAGE STRUCTURE Wound contact surface Thin polymeric film or adhesive Skin or wound facing adhesive layer System for adhesive layer release (e.g., release sheet) Backing layer having particular structural feature (e.g., permeability, shaped, or elasticity, etc.) Tubular TUBULAR BANDAGE APPLICATORS Structure for "press-out" of content unit With rupture means for access With limited access via radial face of "pill box" Compartmented | |
