POLYMER-KLEBEMATRIX MIT SALIFIZIERTEN CARBOXYLGRUPPEN FÜR DIE TRANSDERMALE ANWENDUNG |
摘要 |
Polymeric matrices for the controlled release of medicaments for the topical transdermal use comprising copolymers of acrylic and/or methacrylic acid or esters thereof having a Tg lower than 0° C., whose free carboxy groups are salified with compatible organic or inorganic bases. The matrices of the invention allow to prepare therapeutical systems for the controlled-release of active principles through the transdermal route, thus solving stability, solubility and/or bioavailability problems of the active ingredient within the matrix. |
