  • Publication number: 20170348321
    Abstract: The invention relates to a pharmaceutical composition in the form of a system in film form for transmucosal administration of steroid hormones. An administration system for steroid hormones which dissolves in the mouth and which releases with a high bioavailability is disclosed. The administration system in film form dissolves in the mouth preferably in a period of less than 30 min, and the steroid hormone entering the bloodstream transmucosally from the administration system leads to a rapid rise in the concentration in the blood. It is thus possible to achieve a maximum concentration of this steroid hormone in the blood in a period of less than 60 min after administration.

  • 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.

  • Patent number: 8657986
    Abstract: A method for producing an active substance-containing polyurethane plaster for transdermal application is described, said plaster containing at least one active substance at a highly accurate declared dose. In the described method, a solvent-free active substance-containing polyurethane is produced by reactively coating a solvent-free active substance-containing polyurethane material (40), which is mixed in a coating unit (60) immediately before or during the application process, onto an elastic backing foil (20) that has been rendered non-extensible at least in the direction in which the applied polyurethane material is processed by means of a supporting, adhering auxiliary foil (30) which is at least mono-axially non-extensible.

  • Patent number: 6977083
    Abstract: The method of making a bioadhesive tablet for controlling testosterone blood level, especially in elderly men suffering from partial androgen deficiency, includes spray-drying an alcoholic solution or suspension of testosterone and at least one testosterone ester, preferably in a ratio of 1:10 to 1:1.5, separately or together, with an organic polymer and optionally one or more auxiliary ingredient to form an active ingredient premix. Then various other auxiliary ingredients are mixed, as needed, with the active ingredient premix to form the bioadhesive tablet with an active ingredient layer and an adhesive layer. The active ingredient layer contains an effective amount of the active ingredient premix. The adhesive layer includes auxiliary ingredients including the bioadhesive polymer. The bioadhesive tablet may be buccally administered to provide a predetermined timed release profile of testosterone, advantageously varying according to a circadian rhythm.

  • Publication number: 20020119103
    Abstract: A homogeneous steroid-containing preformulation for production of solid and semi-solid pharmaceutical preparations containing a uniform constant dosage of at least one steroid in a range from 0.001 to 1 percent by weight is described. This steroid-containing preformulation contains of from 0.001 to 50 percent by weight of the at least one steroid. The homogeneous steroid-containing preformulation is made by a method including dissolving the at least one steroid in a solvent to form a dispersant; dispersing an adjuvant consisting of adjuvant particles in the dispersant in a mass ratio of the adjuvant to the at least one steroid of 1:1 to 1000:1 to form a suspension; and creating a spray-mist of the suspension so as to evaporate and remove the solvent from the suspension and thus to form a dried particulate which includes steroid-containing particles. The droplets in the spray mist have a droplet diameter greater than a mean diameter of the adjuvant particles.
