  • Patent number: 11426358
    Abstract: A transparent or translucent medical active substance patch is provided that includes a matrix of monolayer or multilayer configuration with at least one active substance-containing layer contained therein and a backing layer connected with the matrix. The patch, having been applied to the skin of a first person, has a lightness color value L1 at a place of the skin covered by the patch which is not less than 50% and not more than 200% of a lightness color value L2, with L2 being the lightness value of the region of skin of the same person which surrounds the applied patch, with the same being true of the skin of a second or any other person, provided that for all the persons mentioned, the L2 of their respective skin is in the range from 5° to 100°, especially in the range from 20° to 90°.

  • Patent number: 10653636
    Abstract: A medical active substance patch comprising a matrix of monolayer or multilayer configuration with at least one active substance-containing layer and comprising a backing layer connected with the matrix. The active substance patch is transparent or at least translucent, and in the state of having been applied to the skin of a first person, the patch has a lightness colour value L1 at a place of the skin covered by the patch which is not less than 50% and not more than 200% of a lightness colour value L2, L2 being the lightness value of the region of the skin of the same person which surrounds the applied patch.

  • Patent number: 9060955
    Abstract: The invention relates to pharmaceutical formulations, in particular to transdermal therapeutic systems, which are characterized in that little or no active ingredient crystallizes out at the interface between the removable protective film (release liner) and the active-ingredient-containing matrix.

  • Publication number: 20150150827
    Abstract: The UV-stable solid transdermal therapeutic system (TTS) with UV absorber for photosensitive active pharmaceutical ingredients has a backing layer (1), at least one active ingredient-containing matrix (2), and a detachable protective film (3). Optionally an adhesive layer (4) and a separating layer (5) are introduced between the backing layer (1) and the at least one active ingredient-containing matrix (2). At least one hydroxyphenyltriazine compound acting as UV absorber is embedded in the backing layer (1), in the active it matrix (2), or in the adhesive layer (4). The TTS according to the invention achieves high stability at low concentrations of UV absorber, preferably 0.5 to 3% (m/m), so as to reduce or avoid skin irritation.

  • Patent number: 9005653
    Abstract: The present invention relates to a patch comprising a drug-containing layer with low content of hormones, such as gestodene, and optionally an estrogen (e.g. ethinyl estradiol). Upon administering the patch to a woman, plasma levels of at least 1.0 ng/ml of Gestodene is achieved at steady state conditions without the need of incorporating penetration enhancers or permeation enhancers in the drug-containing layer. Satisfactorily plasma levels of the hormones is also achieved throughout a period of at least 1 week, making the patch applicable for being used in female contraception with the concept of administering the patch ones weekly.

  • Patent number: 8323684
    Abstract: The invention relates to a TTS with backing layers that guarantee a high wear comfort and that facilitate application in regions of the human body that are subject to great mechanical loads, especially the large joints of the extremities. The inventive backing layers overcome the disadvantages with respect to reduced absorption of the active substance by the skin that are typically associated with such backing layers. The inventive systems are preferably used for the local of systemic administration of anti-inflammatory and pain-relieving active substances.

  • Patent number: 8226974
    Abstract: The invention relates to transdermal therapeutic systems which have the active ingredient nicotine and have particularly high flexibility. This flexibility decisively improves wearer comfort on the skin, since the system is readily capable of adapting to the surface of the skin and its constant movement. Surprisingly, the nicotine TTS of the invention is markedly more flexible than the conventional nicotine TTS products which are leaders in the market, although at least some of those systems are comparably thin.

  • Publication number: 20110293720
    Abstract: The present invention relates to drug delivery compositions in the form of thin water-soluble films (wafers), which contain small particles that comprise at least one progestin and at least one protective agent. The protective agent provides effective taste-masking of the progestin due to limited release of the progestin in the mouth. The progestin is hence not absorbed via the buccal route, but rather via the enteral (per-oral) route.
