Zusammenfassung
Mittlerweile hat sich die Pflasterapplikation von Medikamenten in vielen Indikationen bewährt. Wir unterscheiden dabei Pflaster zur topischen Anwendung wie beispielsweise Wärmepflaster, von transdermalen Pflastersystemen. Bei den transdermalen Pflastern soll keine lokale Wirkung, sondern eine Abgabe des Wirkstoffes an den Blutkreislauf und somit eine systemische Wirkung erzielt werden. Bekannte Beispiele sind Nikotin-, Estradiol- und Opiatpflaster. In der Parkinson-Therapie steht mit dem Wirkstoff Rotigotin ein Dopaminagonist zur Pflasterapplikation zur Verfügung. Es handelt sich um ein etwa 50 μm dünnes Matrixpflaster mit einer Vielzahl mikroskopisch kleiner Reservoire. Durch die gleichmäßige Wirkstoffabgabe werden konstante Wirkstoffspiegel erreicht, die 1. Leberpassage wird umgangen. Die Pflasterapplikation ist eine mögliche moderne Therapieform beim Parkinson-Syndrom und ergänzt die bestehenden therapeutischen Möglichkeiten.
Abstract
For many indications, the application of medication by patch has meanwhile become an established practice. We distinguish between patches with a topical action – hot patches, for instance – and transdermal patch systems. Transdermal patches are not meant to have a local effect. By release of the active ingredient to the circulation they are designed to produce a systemic effect. Nicotine, estradiol and opiate patches are well-known representatives in this respect. In the treatment of Parkinson's disease, the dopamine agonist – rotigotine – has been tailored for patch application. This is a thin matrix patch of about 50 µm with a great number of microscopically small reservoirs. A constant therapeutic level is maintained by consistent release, first passage through the liver is circumvented. Patch application is a possible new way to treat Parkinson's disease and supplements the existing therapies.
