Title (EN) HYALURONIC ACID GEL WITH A DIVALENT CATION
(FR) GEL D'ACIDE HYALURONIQUE AVEC UN CATION DIVALENT
Abstract:
(EN) The present invention relates to a method of preparing a sterilized injectable hydrogel composition, comprising the steps: a) providing an amide crosslinked glycosaminoglycan, b) swelling the amide crosslinked glycosaminoglycan in a solution comprising a divalent cation to form a hydrogel composition, and c) sterilizing the hydrogel composition by autoclaving to form a sterilized injectable hydrogel composition, and to sterilized injectable hydrogel compositions obtainable by such method.
(FR) La présente invention concerne un procédé de préparation d'une composition d'hydrogel injectable stérilisée, comprenant les étapes consistant à : a) prendre un glycosaminoglycane réticulé par liaison amide, b) faire gonfler le glycosaminoglycane réticulé par liaison amide dans une solution comprenant un cation divalent pour former une composition d'hydrogel, et c) stériliser la composition d'hydrogel par autoclavage pour former une composition d'hydrogel injectable stérilisée. L’invention concerne également des compositions d'hydrogel injectables stérilisées pouvant être obtenues par ledit procédé.
