  • Publication number: 20150335658
    Abstract: The invention relates to a UV stable transdermal therapeutic system (TTS) consisting of a back layer, at least one matrix containing an active substance and optionally, a withdrawal film and an UV-radiation absorber. An adhesive layer containing said UV-radiation absorber is arranged between the back layer and the matrix containing an active substance which is distant as much as possible from a surface, a separation layer is arranged between the adhesive layer containing said UV-radiation absorber and the matrix containing an active substance, which is as remote as possible from the surface which is impermeable to the active substance and UV-radiation absorber. The inventive transdermal therapeutic system exhibits a high stability and is devoid of inconveniences of existing TTS containing a light-sensitive substance.

  • 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.

  • Publication number: 20070243240
    Abstract: The invention concerns a transdermal therapeutic system containing ergoline derivatives, preferably lisuride, with a stabilized ergoline compound. Stabilization of the oxidation sensitive ergoline combination is done through a combination of at least one fat-soluble, radical-trapping antioxidant, preferably Di-tert.-butylmethylphenols, Di-tert.-butylmetoxyphenols, tocopherols or ubichinones and a basic polymer. Use of a transdermal therapeutic system (TTS) comprising a pharmaceutical layer containing at least one matrix having an active ingredient and/or an active ingredient reservoir; a diffusion barrier that is permeable to said active ingredient and arranged on the skin side of the active ingredient reservoir; and an ergoline derivative or salt thereof as an active ingredient for producing an agent for obtaining and maintaining the circadian rhythm under dopamine therapy.
