  • Publication number: 20220079887
    Abstract: The present invention relates to a transdermal therapeutic system (1) comprising an active-substance carrier layer (2) having at least one active-substance-containing polymer matrix (3) applied to the active-substance carrier layer (2), said matrix comprising at least one pressure-sensitive adhesive and at least one pharmacologically active substance absorbable through human or animal skin, and an adhesive carrier layer (6) coated as completely as possible with an active-substance-free pressure-sensitive adhesive (7), said adhesive carrier layer being bonded by means of the active-substance-free pressure-sensitive adhesive (7) directly to the flat side of the active-substance carrier layer (2) facing away from the active-substance-containing polymer matrix (3), wherein the adhesive carrier layer (6) projecting circumferentially beyond the edge of the active-substance carrier layer (2), wherein the system is characterized in that between the active-substance-containing polymer matrix (3) and the active-sub

  • Publication number: 20210290560
    Abstract: The present invention relates to a transdermal therapeutic system without a release-determining membrane for delivering scopolamine, comprising a skin contact layer, an active substance-containing reservoir layer, an active substance-impermeable backing layer, and optionally a protective layer which is detachable from the skin contact layer, wherein the skin contact layer is in direct contact with the active substance-containing reservoir layer. The skin layer or the skin layer and the reservoir layer may be equipped with adhesive strength-increasing additives, for example silicone oils. Furthermore, the system may be equipped with an active substance-free over-patch in order to ensure a sufficient adhesion onto the skin over the application duration. In comparison to comparable systems with a release-determining membrane, a similar bioavailability of the active substance was achieved, such that these systems are bioequivalent to the membrane-containing systems.
