摘要: A dry-state iontophoretic drug delivery device (10, 70, 80) is provided. The device has drug and electrolyte reservoirs (15, 16) which are initially in a non-hydrated condition. A liquid-containing pouch (21, 22) is provided. In certain embodiments the liquid is contained in breakable capsules within the pouch. Water or other liquid can be released from the capsules in the pouch by squeezing or flexing the pouches (21,22). Alternatively, the liquid can be released from the pouches (21,22) using pouch piercing pins (36,37). The liquid released from the pouches (21,22) hydrates the drug and electrolyte reservoirs (15, 16) and activates the device. In another embodiment, the device (20, 20a) has liquid-containing gel layers (31,32) which are initially separated from their respective electrode assemblies (8, 9). Liquid-wicking pathways (27,28) are provided to carry the liquid from the gel layers (31,32) to the drug and electrolyte layers (15, 16).

摘要: An electrically powered iontophoretic delivery device is provided. The device utilizes electrodes composed of a preferably hydrophobic polymeric matrix. The matrix contains about 10 to 50 vol % of a material capable of absorbing a liquid solvent, typically water, to provide a plurality of ion conducting pathways through the matrix. The matrix also contains about 5 to 40 vol % of a chemical species which is able to undergo either oxidation or reduction during operation of the device. Preferably, the solvent absorbing material is a hydrophilic polymer such as polyvinylpyrrolidone. For the anodic electrode, the chemical species should be able to undergo oxidation and is preferably either silver or zinc. For the cathodic electrode, the chemical species should be able to undergo reduction and is preferably silver chloride or a reducible metal.

摘要: An electrically powered transdermal iontophoretic delivery device (10, 20) and a method of making same is provided. The device utilizes electrode assemblies (8, 9) composed of a substantially homogenous blend of a polymeric matrix containing about 5 to 50 vol % of a conductive filler which forms a conductive network through the matrix, and up to about 50 vol % of the agent to be iontophoretically delivered through the skin. In the case of the donor electrode assembly, the agent is typically a drug and preferably a water soluble drug salt. In the case of the counter electrode assembly, the agent is typically an electrolyte salt. The homogenous blend eliminates the need for separate electrode and agent containing layers which require lamination.

摘要: The invention is directed to a device for delivering an active agent formulation for a predetermined administration period. An impermeable reservoir is divided into a water-swellable agent chamber and an active agent formulation chamber. Fluid from the environment is imbibed through a semipermeable plug into the water-swellable agent chamber and the active agent formulation is released through a back-diffusion regulating outlet. Delivery periods of up to 2 years are achieved.
