Abstract
La presente invención se refiere a un sistema de dosificación transdérmica, adhesivo, de capa doble, para la liberación sostenida de un medicamento farmacéuticamente activo a la piel de un paciente humano, que comprende: (i) una primera capa componente formada de una lámina esencialmente plana que contiene un medicamento farmacéuticamente activo de un adhesivo acrílico, sensible a la presión, al menos parcialmente eslabonado transversalmente, la lámina esencialmente plana comprendiendo un polímero de adrilato eslabonado transversalmente, de auto-sostén, flexible, de sificiente adhesividad, durabilidad y resistencia mediante el cual se mantiene contacto difusional íntimo con la piel del paciente por un período de al menos 24 horas sin destrucción de la integridad física de la lámina, la lámina esencialmente plana siendo capaz de retener ahí disperso suficiente medicamento farmacéuticamente activo para suministrar a la piel una cantidad farmacéuticamente activa del medicamento farmacéuticamente activo en un intervalo de 24 horas, sin disolución del adhesivo acrílico sensible a la presión, al menos parcialmente eslabonado transversalmente, y (ii) una segunda capa componente íntimamente adherida a un lado de la primera capa componente, la segunda capa componente siendo resistente al paso del medicamento farmacéuticamente activo desde la primera capa componente.The present invention relates to a double-layer, adhesive, transdermal dosing system for the sustained release of a pharmaceutically active drug to the skin of a human patient, comprising: (i) a first component layer formed of essentially a sheet flat containing a pharmaceutically active medicament of a pressure-sensitive acrylic adhesive, at least partially cross-linked, the essentially flat sheet comprising a flexible, self-supporting, cross-linked adrylate polymer of sufficient adhesiveness, durability and strength by which maintains intimate diffusion contact with the patient's skin for a period of at least 24 hours without destruction of the physical integrity of the sheet, the essentially flat sheet being able to retain there dispersed enough pharmaceutically active medication to supply the skin with a pharmaceutically active amount of m pharmaceutically active edicament within 24 hours, without dissolution of the pressure sensitive acrylic adhesive, at least partially cross-linked, and (ii) a second component layer closely adhered to one side of the first component layer, the second component layer being resistant to the passage of the pharmaceutically active drug from the first component layer.
