Abstract
An iontophoretic drug delivery device storage apparatus and a method of using that device is disclosed. The device comprises a fluid reservoir, an electrode assembly and a tray apparatus. The fluid reservoir is capable of retaining a medicament and has a sealed fluid chamber defined by at least one seal. The seal includes a weaker region and a pinch-like configuration associated with that region such that application of pressure to the fluid reservoir breaks the weaker region of the seal, releasing the retained medicament. The electrode assembly comprises an active electrode, at least two passive electrodes a medicament carrying region, and a moat region around the medicament carrying region so that once fluid is delivered from the fluid reservoir to the electrode assembly the fluid is substantially retained in the medicament carrying means.
