Title (EN) DELAYED RELEASE DELIVERY SYSTEMS AND METHODS
(FR) SYSTÈMES ET MÉTHODES D'ADMINISTRATION À ACTION RETARDÉE
Abstract: front page image
(EN)A delayed release delivery system comprises a hydrophilic core particle having surface pores and containing a liquid. The particle is encapsulated in a polymer having a hydrophobic backbone and hydrophilic pendant groups. At least some of the surface pores adjacent the hydrophilic pendant groups are blocked in the presence of water and unblocked in the absence of water. The treated particle contains liquid in a weight ratio of the liquid to the porous core particle of at least 400:1.
(FR)L'invention concerne un système d'administration à action retardée comprenant une particule de noyau hydrophile comportant des pores de surface et contenant un liquide. La particule est encapsulée dans un polymère pourvu d'un squelette hydrophobe et de groupes pendants hydrophiles. Au moins certains des pores de surface adjacents aux groupes pendants hydrophiles sont bloqués en présence d'eau et débloqués en l'absence d'eau. La particule traitée contient un liquide dans un rapport en poids liquide-particule de noyau poreux d'au moins 400:1.
