Abstract

An adhesive patch is provided that allows the user to apply it in a safe and hygienic manner without touching the drug-containing matrix during the sequence of actions from the removal of the liner to the application of the patch. Specifically, the adhesive patch has a multilayer structure that includes a backing, an adhesive drug-containing matrix that is spread substantially entirely over one surface of the backing, and a liner that adheres to the drug-containing matrix surface. The adhesive patches have the following features:(a) the liner adhering to the drug-containing matrix surface includes first and second liners;(b) the first liner is folded at the middle thereof so that it is divided by the fold into first and second sections that together form a V-shaped liner, the first section adhering to the drug-containing matrix surface from one end of the matrix with the fold arranged closer to the middle of the drug-containing matrix, the second section serving as a tab; and(c) the second liner adheres to the remaining part of the drug-containing matrix surface with one end of the second liner covering the fold of the V-shaped first liner to form a laminated part that serves as a tab.
