An adhesive patch, such as poultice-type patch, is provided, which is suitable for mass production and allows the user to apply it without touching the drug-containing matrix. A production method of such a adhesive patch is also provided. Specifically, the method for producing adhesive patch, wherein (a) the adhesive patch comprises two liners; (b) the first liner is folded at the middle thereof so that it is divided by the fold into two sections that together form a V--shaped liner, one of the two sections adhering to the drug-containing matrix surface; 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, the method including: allowing a tubular liner to adhere to at least half of the surface of the drug-containing matrix spread over the backing; and cutting the tubular liner in half to form the V-shaped first liner folded at the middle thereof.
L'invention concerne un procédé de production d'un timbre transdermique (1) qui présente une structure stratifiée comprenant un support (2), un onguent collant (3) étalé sur presque toute une face du support (2) et deux films détachables (41 et 42) collés sur la surface de l'onguent. Le premier film détachable (41) est un film détachable en forme de V plié en son centre et collé sur la surface de l'onguent de sorte que la partie pliée d'une face de ce film détachable en forme de V se trouve face au centre de l'onguent, tandis que le second film détachable (42) est collé sur la partie restante de la surface de l'onguent de sorte que le bord (47) de ce second film détachable couvre la partie pliée du premier film détachable. L'invention se caractérise en ce qu'au moins une moitié de la surface de l'onguent étalé sur le support (2) est collée à un film détachable tubulaire, puis ce film détachable tubulaire est partagé en deux de façon à former le premier film détachable plié en son centre.
