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.

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).
