Abstract

SYSTEME D'APPORT DE SUBSTANCES ACTIVES PAR DIFFUSION, DU TYPE A RESERVOIR, COMPRENANT UN MELANGE D'UN EXCES DE LA SUBSTANCE ACTIVE 16 DANS UN VEHICULE 17 QUI EST PERMEABLE A CETTE SUBSTANCE ET DANS LEQUEL CELLE-CI N'A QU'UNE SOLUBILITE LIMITEE, CE MELANGE ETANT CONTENU DANS UNE PAROI 12, 13 DE MATIERE POLYMERE QUI EST MOINS RAPIDEMENT PERMEABLE A LA SUBSTANCE ACTIVE QUE NE L'EST LE VEHICULE, ET DONT LA PERMEABILITE A L'EAU EST LIMITEE. CE SYSTEME EST CARACTERISE EN CE QUE LE VEHICULE EST CONSTITUE PAR UN COPOLYMERE SEQUENCE D'OXYDE D'ETHYLENE ET D'OXYDE DE PROPYLENE AYANT UNE MASSE MOLECULAIRE D'ENVIRON 2.000 A 10.000 ET DONT L'OXYDE D'ETHYLENE CONSTITUE ENVIRON 10 A 80 DE SON POIDS. UTILISATION POUR L'APPORT DE MEDICAMENTS PAR EXEMPLE AU TUBE DIGESTIF, OU DE CONTRACEPTIFS AU MOYEN D'UN DISPOSITIF INTRA-UTERIN.SYSTEM FOR THE DELIVERY OF ACTIVE SUBSTANCES BY DIFFUSION, OF THE TANK TYPE, INCLUDING A MIXTURE OF AN EXCESS OF THE ACTIVE SUBSTANCE 16 IN A VEHICLE 17 WHICH IS PERMEABLE TO THIS SUBSTANCE AND IN WHICH THE latter ONLY HAS SOLUBILITY LIMITED, THIS MIXTURE IS CONTAINED IN A WALL 12, 13 OF POLYMERIC MATERIAL WHICH IS LESS PERMANENTLY PERMEABLE TO THE ACTIVE SUBSTANCE THAN IS THE VEHICLE, AND WHOSE PERMEABILITY TO WATER IS LIMITED. THIS SYSTEM IS CHARACTERIZED IN THAT THE VEHICLE CONSISTS OF A COPOLYMER SEQUENCE OF ETHYLENE OXIDE AND OF PROPYLENE OXIDE HAVING A MOLECULAR MASS OF ABOUT 2,000 TO 10,000 AND OF WHICH ETHYLENE OXIDE CONSTITUTES ABOUT 10 TO 80 OF ITS WEIGHT. USE FOR DELIVERY OF MEDICINES, FOR EXAMPLE TO THE DIGESTIVE TUBE, OR OF CONTRACEPTIVES BY MEANS OF AN INTRA-UTERINE DEVICE.
