Patent

CA 2664545

A bioresorbable polymer is obtained by reacting together (a) a prepolymer comprising co-polymerised units of a caprolactone and poly(alkylene oxide) moieties; (b) a polycapro lactone diol comprising co-polymerised units of a caprolactone and a C2-C6 diol; and (c) a diisocyanate. The polymer may be loaded with a pharmaceutically active agent to produce a drug delivery device.

Polymère biorésorbable obtenu en faisant réagir ensemble (a) un prépolymère comprenant des unités copolymérisées d'une caprolactone et d'entités de type poly(oxyde d'alkylène) ; (b) un polymère de caprolactone et d'un diol comprenant des unités copolymérisées d'une caprolactone et d'un diol en C2-C6 ; et (c) un diisocyanate. On peut charger le polymère avec un agent actif du point de vue pharmaceutique pour produire un dispositif d'administration de médicament.
