Hydroxyguanidines are useful for the manufacture of a medicament for treatment or prevention of an ischemic disease condition including an ischemic condition caused by surgery or other therapy and being associated with the production of oxygen derived radicals, the disease condition being a xanthine oxidase/xanthine dehydrogenase mediated ischemic condition selected from heart infarction, angina pectoris, cerebrovascular infarction, circulatory shock, transient ischemic attacks of the cerebrovascular system, arterial occlusion, arterial thromboembolism, bowel torsion with strangulation, testicular torsion, lung embolus, cardiac surgery including by-pass grafting, and localised organ surgery involving reduced blood flow, organ transplantation, circulatory shock, and general hypoxia. Preferred hydroxyguanidines are carbimino hydroxyguanidines, in particular aryl carbimino hydroxyguanidines. Also disclosed are corresponding methods of treatment, including extracorporeal treatment of organs, and a number of hydroxyguanidines.

Les hydroxyguanidines sont utiles pour la fabrication d'un médicament destiné au traitement ou à la prévention des pathologies à ischémie, y compris les cas d'ischémies consécutifs à un acte chirurgical ou à une autre thérapie et liés à la production de radicaux dérivés de l'oxygène. Les cas d'ischémie considérés sont des états ischémiques à médiation par xanthine oxydase/xanthine déshydrogénase consécutifs à l'infarctus du myocarde, l'angine de poitrine, l'infarctus cérébro-vasculaire, le choc circulatoire, les attaques ischémiques passagères du système cérébro-vasculaire, l'occlusion artérielle, la thrombo-embolie artérielle, la torsion intestinale avec étranglement, la torsion testiculaire, l'embole pulmonaire, la chirurgie cardiaque y compris le pontage, ainsi que la chirurgie localisée à un organe impliquant une réduction du débit sanguin, la transplantation d'organe, le choc circulatoire et l'hypoxie généralisée. Les hydroxyguanidines préférées sont les carbimo hydroxyguanidines, et en particulier les aryl carbimo hydroxyguanidines. L'invention concerne également des thérapies et notamment le traitement extracorporel d'organes et un certain nombre d'hydroxyguanidines.
