Abstract

La présente invention concerne une composition et une méthode de traitement de l'arthrite, ladite composition comprenant au moins un glycosaminoglycane combiné à au moins un inhibiteur d'hyaluronidase. Dans un mode de réalisation préféré, la présente invention concerne une composition et une méthode de traitement de l'arthrite, ladite composition comprenant au moins un glycosaminoglycane qui comprend au moins de l'acide hyaluronique combiné à au moins un inhibiteur d'hyaluronidase sélectionné dans le groupe constitué d'héparane sulfate, de dextrane sulfate et de xylose sulphate. Dans un autre mode de réalisation préféré encore, la présente invention concerne une composition et une méthode de traitement de l'arthrite, ladite composition comprenant de l'acide hyaluronique co-encapsulé avec un inhibiteur d'hyaluronidase présent dans les liposomes. L'acide hyaluronique présent dans la composition confère les propriétés de viscosupplément à l'articulation. La fonction de l'inhibiteur d'hyaluronidase est d'agir en tant qu'un conservateur, et de protéger l'acide hyaluronique contre la dégradation prématurée au niveau de l'articulation. L'encapsulation liposomale et la libération de ladite composition sert de dépôt à libération lente pour l'acide hyaluronique et de l'inhibiteur d'hyaluronidase. Ladite invention concerne par conséquent un moyen d'administration stable et de longue durée d'acide hyaluronique (HA) de poids moléculaire élevé au niveau de l'articulation. L'efficacité thérapeutique de l'acide hyaluronique encapsulé dans le liposome avec l'inhibiteur d'hyaluronidase est supérieur à une simple injection d'acide hyaluronique. La méthode de traitement préférée est une injection intra-articulaire d'un mélange d'acide hyaluronique et d'un inhibiteur d'hyaluronidase, éventuellement encapsulés dans des liposomes. Le traitement est plus efficace que les traitements actuellement disponibles reposant sur le seul HA.
