The present invention is based upon the novel observation of the COX-II- specific inhibitory activity of gamma-tocopherol and that by combining gamma- tocopherol with precursors of connective tissue constituents, injured or degenerated connective tissue, especially of articulated joints of animal patients, may be repaired. The method of the invention for treating a inflammatory disorder of a joint comprises administering to the mammal a pharmaceutical composition comprising an amount of gamma-tocopherol effective in selectively inhibiting cyclooxygenase-2 and at least one compound that elevates the production of a component of connective tissue in an amount effective for the promotion of connective tissue formation. The invention also provides pharmaceutical or veterinary compositions comprising a tocopherol preparation having at least 50% w/w gamma- tocopherol or a derivative thereof and in an amount effective for selectively inhibiting cyclooxygenase-2 in the recipient mammal and at least one compound that elevates the production of a component of connective tissue.

La présente invention repose sur la nouvelle observation de l'activité inhibitrice spécifique de COX-II du gamma-tocophérol et sur le fait que l'utilisation conjointe de gamma-tocophérol avec des précurseurs de constituants du tissu conjonctif permet de réparer un tissu conjonctif blessé ou dégénéré, en particulier des articulation de patients mammifères. La méthode de l'invention, destinée au traitement d'un trouble inflammatoire d'une articulation, consiste à administrer au mammifère une composition pharmaceutique contenant une dose suffisante de gamma-tocophérol pour inhiber la cyclooxygénase-2 et au moins un composé permettant d'augmenter la production d'un composant du tissu conjonctif en quantité suffisante pour promouvoir la formation de tissu conjonctif. L'invention concerne également des compositions à usage pharmaceutique ou vétérinaire comprenant une préparation à base de tocophérol contenant au moins 50 % en poids de gamma-tocophérol ou d'un dérivé de gamma-tocophérol, en quantité suffisante pour inhiber de façon sélective la cyclooxygénase-2 chez le mammifère hôte, et au moins un composé permettant d'augmenter la production d'un composant du tissu conjonctif.
