Use of compounds of formula (I) ##STR1## to provide a more effective delivery of oxygen to the tissues of a mammalian, including human, recipient. In vivo applications include the relief or amelioration of conditions wherein there is tissue hypoxia; in vitro the compounds are of use in the storage of mammalian, including human, red blood cells to maintain their oxygen-delivery capacity and prolong their useful storage life. Also provided is a sterile, sealed vessel containing an anticoagulant, a non-toxic amount of a compound of formula (I) and optionally mammalian, in particular human, red blood cells.
A method for treatment of a vascular or cardiovascular condition or acute coronary syndromes comprises administering an effective amount of a flavone 8-carboxylic acid to a mammal suffering from a vascular or cardiovascular condition or acute coronary syndromes. The flavone 8-carboxylic acid is typically flavone 8-acetic acid. The flavone 8-carboxylic acid can be administered alone or in combination with another agent such as a thrombolytic agent, an antithrombotic agent, an anticoagulant, or an antiplatelet agent. The invention also includes pharmaceutical compositions formulated for the treatment of a vascular or cardiovascular condition or acute coronary syndromes.
