  • Patent number: 6156336
    Abstract: Active ingredient-containing layered articles or discs which are suitable, in particular, as active ingredient reservoirs for transdermal therapeutic systems are obtained starting from an elongate article having an enveloping surface corresponding to the contour of the layered articles to be produced, and having a cross-sectional constitution corresponding to the internal structure of the layered articles, by layered detachment perpendicular to the axial direction of the elongate article. In the simplest case, this article consists of a uniform active ingredient-containing composition and forms a solid cylinder which is converted into single products perpendicular to the axis with identical spacing to result in circular one-compartment discs identical to one another.

  • Patent number: 6080421
    Abstract: The invention refers to a transdermal therapeutic system for the delivery of active agents to the human body.The backing layer consists of common pharmaceutical plastic layer laminates which require labeling, e.g. by printing. The problem to solve lies in toxicological, technological and drug law disadvantages of pigment- or varnish-printing.According to the invention, the coding does not consist of an ink- or pigment layer but in an effect on surface properties of the backing layer corresponding to the coding.

  • Patent number: 6059913
    Abstract: A process for the continuous production of transdermal therapeutic patches, wherein a laminate of an auxiliary layer (3) siliconized at least on one side, an active substance-containing, pressure-sensitive adhesive layer (4), and a supporting layer (9) is prepared as a strip-shaped web (1) first, and the active substance-containing sections (4') obtained by punching said layers (3) and (4) across the web direction are intermittently transferred onto a second web (2), the punching procedure taking place in the rest phase between the cycles and the transfer procedure onto the second web (2) being carried out preferably at equal distances by means of a transfer device (11, 12), is characterized by the fact that the supporting layer (9) is stripped from the active substance-containing sections (4') during the transfer first, and that then the sections (3') of the auxiliary layer are removed with the aid of a process layer (5) which has been rendered pressure-sensitive adhesive.
