Abstract

SE PRESENTA UN DISPOSITIVO DE SUMINISTRO IONTOFORETICO, TRANSDERMICO, ELECTRICAMENTE ALIMENTADO (10, 20) Y UN METODO PARA FABRICAR EL MISMO. EL DISPOSITIVO UTILIZA UNOS ELECTRODOS (8, 9) COMPUESTOS DE UNA MEZCLA SUBSTANCIALMENTE HOMOGENEA DE UNA MATRIZ POLIMERICA QUE CONTIENE ALREDEDOR DE UN 5 Y UN 50% DE SU VOLUMEN DE UN RELLENO CONDUCTOR QUE FORMA UNA RED CONDUCTORA A TRAVES DE LA MATRIZ Y HASTA ALREDEDOR DE UN 50% DEL VOLUMEN DE UN AGENTE QUE SERA IONTOFORETICAMENTE SUMINISTRADO A TRAVES DE LA PIEL. EN EL CASO DEL ELECTRODO DONANTE, EL AGENTE ES TIPICAMENTE UNA DROGA Y PREFERIBLEMENTE UNA SAL DE UNA DROGA SOLUBLE EN AGUA. EN EL CASO DEL ELECTRODO CONTRARIO, EL AGENTE ES TIPICAMENTE UNA SAL DE ELECTROLITO. LA MEZCLA HOMOGENEA ELIMINA LA NECESIDAD DE ELECTRODOS SEPARADOS Y AGENTES QUE CONTENGAN CAPAS QUE REQUIERAN LAMINACION.
