Transdermal therapeutic systems having improved stability and their production

Topical plaster with non-steroidal antirheumatic agents with an acid group

A process for manufacturing transdermal systems comprising free active substance bases is characterized in that the free active substance base is liberated, during the manufacture of the system, from active substance salts by conversion with a basic alkaline metal salt.

Use of basic alkali metal salts for manufacturing transdermal therapeutic system

Transdermal therapeutic system containing the active substance scopolamine base

A transdermal or topical plaster system with a backing layer, with an active ingredient-containing and self-adhesive matrix based on crosslinkable polyacrylate as base polymer and with a removable protecting film is characterized by an at least two-layer matrix with a degree of crosslinking of the layer facing the skin which is appropriate for adequate adhesion to the skin thereof and is lower than the degree of crosslinking of the layer or layers on top thereof.

Transdermal or topical plaster system with a polyacrylate matrix with improved physical properties

In a solid medicament form for the peroral application of active agents containing a uniform distribution of active agent in a polymer material, the polymer material is in the form of flat fragments.

Solid medicament form with active agent distributed in flat polymer fragments

An active ingredient-containing transdermal therapeutic system with a nonadhesive backing layer, with an active ingredient-containing reservoir layer and with a self-adhesive surface facing the skin, where appropriate with redetachable protecting layer, is characterized by an elastic or plastically extensible diffusible backing layer with a metal layer which acts as permeability barrier for auxiliaries and active ingredients in the reservoir layer and is formed by film growth, in particular a metallization layer.
