摘要：
The invention relates to a method of treating pain in a patient by applying a transdermal therapeutic system for the transdermal administration of buprenorphine for 7 days on the skin of a patient, said transdermal therapeutic system comprising a buprenorphine-containing self-adhesive layer structure comprising A) a buprenorphine-impermeable backing layer, and B) a buprenorphine-containing matrix layer on said buprenorphine- impermeable backing layer, the matrix layer comprising a) a polymer base, b) buprenorphine, and c) a carboxylic acid selected from the group consisting of oleic acid, linoleic acid, linolenic acid, levulinic acid and mixtures thereof, in an amount sufficient so that said buprenorphine is solubilized therein to form a mixture, and the carboxylic acid buprenorphine mixture forms dispersed deposits in the polymer base, and C) a skin contact layer on said buprenorphine-containing matrix layer comprising a polymer-based pressure-sensitive adhesive, and optionally wherein the buprenorphine-containing self-adhesive layer structure contains said buprenorphine in an amount of less than 0.8 mg/cm2 buprenorphine base or an equimolar amount of a pharmaceutically acceptable salt thereof.La invención se relaciona con un método de tratamiento del dolor en un paciente al aplicar un sistema terapéutico transdérmico para la administración transdérmica de buprenorfina por 7 días sobre la piel de un paciente, dicho sistema terapéutico transdérmico comprendiendo una estructura de capa autoadhesiva conteniendo buprenorfina que comprende A) una capa de respaldo impermeable a la buprenorfina, y B) una capa matricial conteniendo buprenorfina sobre dicha capa de respaldo impermeable a la buprenorfina, la capa matricial comprendiendo a) una base polimérica, b) buprenorfina, y c) un ácido carboxílico seleccionado del grupo consistente de ácido oleico, ácido linoleico, ácido linolénico, ácido levulínico y mezclas de los mismos, en una cantidad suficiente para que dicha bu
