  • Method for improving tissue antioxidant status
    Patent number: 5516778
    Abstract: The invention relates to a method of using 3,7-dihydro-3,7-dimethyl-1-(5-oxohexyl)-1H-purine-2,6-dione (generic name:pentoxifylline) and/or 1-(3',4'-diethoxybenzyl)-6,7-diethoxy-3,4 -dihydroisoquinolinium theophylline-7-acetate (Depogen) or monohydrate thereof to improve mammalian tissue antioxidant status. This status plays an important role in complications, occurring as a consequence of pathologically developed or artificially established anastomoses, particularly anastomosis of oesophagus and colon since these organs possess a very weak antioxidant protective system.
