description | COMPRENDE: A)UNA CAPA DE BASE; B)POR LO MENOS UNA MATRIZ QUE CONTIENE SUSTANCIA ACTIVA; Y, OPCIONALMENTE, C)UNA PELICULA DESPEGABLE QUE CONTIENE ADEMAS UN AGENTE ABSORBEDOR DE RAYOS UV, CARACTERIZADO PORQUE : i)ENTRE (A) Y (B) QUE ESTA MAS ALEJADA DE LA SUPERFICIE DE LA PIEL, SE PREVE POR LO MENOS UNA CAPA ADHESIVA QUE CONTIENE UN AGENTE ABSORBEDOR DE RAYOS UV, QUE SON UNA SUSTANCIA O MEZCLA DE SUSTANCIAS, SELECCIONADOS DE: ACIDO DE AMINOBENZOICO; ii)ENTRE LA CAPA ADHESIVA QUE CONTIENE EL AGENTE ABSORBEDOR DE RAYOS UV Y (B), HAY POR LO MENOS UNA CAPA SEPARADORA QUE ES IMPERMEABLE A LA SUSTANCIA ACTIVA E IMPERMEABLE AL AGENTE ABSORBEDOR DE RAYOS UV, QUE ES SELECCIONADA DE: POLIMERO DE BARRERA, PREFERENTEMENTE DE TEREFTALATO DE POLIETILENO, POLIACRILNITRILO, CLORURO DE POLIVINILO, CLORURO DE POLIVINILIDENO O SUS COPOLIMEROS O CO-LAMINADOS. ASIMISMO, LA MATRIZ Y/O LA CAPA ADHESIVA ES/SON AUTOADHESIVAS Y CONSISTE(N) EN POLIMEROS SELECCIONADOS DEL/DE LOS GRUPOS POLIISOBUTILENO, POLIBUTENO, POLIACRILATO, POLIDIMETILSILOXANO, POLIMERIZADOS DE BLOQUE DE ESTIRENO-ISOPRENO O POLIISOPRENO. EL SISTEMA TERAPEUTICO TRANSDERMICO (TTS) DESCRITO POSEE GRAN ESTABILIDAD Y NO TIENE SUSTANCIAS ACTIVAS SENSIBLES A LA LUZ TRADICIONAL
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. |
