Abstract
Patente de Invenção: <B>"ESTERES DE áCIDO GRAXO DE áCIDO GLICóLICO E SEUS SAIS COMO REALçADORES DE PERMEAçãO"<D>. Um sistema de liberação transdérmica de medicamento, que acentua a liberação do medicamento, compreende uma composição contendo, como um reforçador, um ou mais C~ 5~ a C~ 21~ ésteres de ácido graxo de ácido glicórico e seus sais. Estas composições são compostas de uma quantidade segura de um permeante farmacêutico ativo contido em num veículo de intensificação da penetração, compreendendo de 0,25 a 50% em peso do acentuador de éster de ácido graxos em um veículo portador adequado. Estes reforçadores de éster de ácido glicórico de ácidos graxos podem ser usados em vários veículos portadores para acentuar a liberação transdérmica dos permeantes ativos, ou na forma livre ou usado em um dispositivo oclusivo, particularmente em um emplastro transdérmico na forma de matriz ou de reservatório. Quando usado na forma de emplastro de matriz, os reforçadores de éster de ácido glicórico de ácidos graxos e os permeantes são incorporados em um adesivo biocompatível. quando usado em um emplastro tipo reservatório, o permeante e os reforçadores de éster de ácido glicórico de ácidos graxos são incorporados em um fluido portador de viscosidade controlada, tal como um gel ou um unguento, preferivelmente contendo um alcanol inferior e água. Na forma livre o reforçador e o permeante podem ser incorporados em um unguento, loção, creme ou formulação similar.
