LAYERED DRUG DELIVERY DEVICE |
摘要 |
The layered drag delivery devices of the present invention have an outer side and an inner side. The device includes, in order from the outer side to the inner side, a first layer and a second layer. The first layer is water insoluble, water swellable, and water permeable. The second layer includes a therapeutic amount of a water soluble drug and a water soluble mucoadhesive film. The second layer is disposed such that water passing through said first layer solubilizes the drug. The said solubilized drug then can permeate through a mucosal membrane when the inner side is in contact with the mucosal membrane. The drug delivery device is in sheet form. |
