Abstract
El invento se refiere a un nuevo sistema terapéutico transdérmico estable a los rayos UV [TTS] que consiste en una capa de base, por lo menos una matriz que contiene sustancia activa y opcionalmente una película despegable y además un agente absorbedor de rayos UV, donde entre la capa de base y la matriz que contiene sustancia activa, que se encuentra más alejada de la superficie de la piel, se prevé por lo menos una capa adhesiva que contiene agente absorbedor de rayos UV y entre la capa adhesiva que contiene el agente adsorbedor de rayos UV y la matriz que contiene sustancia activa, que está más alejada de la superficie de la piel, se prevé por lo menos una capa separadora que es impermeable a la sustancia activa e impermeable al agente absorbedor de rayos UV. El sistema terapéutico transdérmico de la invención posee gran estabilidad y no tiene las desventajas de los TTS que contienen sustancias activas sensibles a la luz tradicionales.The invention relates to a new transdermal therapeutic system stable to UV rays [TTS] consisting of a base layer, at least one matrix containing active substance and optionally a detachable film and also a UV absorbing agent, where between the base layer and the matrix containing active substance, which is furthest from the surface of the skin, at least one adhesive layer containing UV absorbing agent is provided and between the adhesive layer containing the adsorbing agent of UV rays and the matrix containing active substance, which is further away from the surface of the skin, at least one separating layer is provided that is impermeable to the active substance and impermeable to the UV absorbing agent. The transdermal therapeutic system of the invention has great stability and does not have the disadvantages of TTS containing traditional light sensitive active substances.
