Abstract
A dry-state iontophoretic drug delivery device (10, 30) is provided. The device has drug and electrolyte reservoirs (15, 16) which are initially in a non-hydrated condition. In one embodiment of the invention, a sealed liquid-containing pouch (21, 22) is provided in each electrode assembly (8, 9). Water or other liquid (20) is released from the pouch (21, 22) by pulling a tab (27, 28) attached to a portion (25, 26) of the pouch (21, 22) which is capable of being torn or ripped in order to hydrate the drug and electrolyte reservoirs (15, 16) and activate the device (10, 30). In another embodiment, the device (30) is held in a package (32). The device (30) has pouches (21, 22) which release their liquid contents automatically upon removal of the device (30) from the package (32). In yet another embodiment, the device (40) is held in a package (42) having a compression zone (46). The pouches (21, 22) must be moved through the compression zone (46) when removing the device (40) from the package (42). Compression causes the pouches (21, 22) to rupture and release the hydrating liquid (20).
