  • Publication number: 20080312138
    Abstract: The present invention provides methods and compositions to replace up to 90% of erythropoietin use in the treatment of anemias and hypoxias. The method employs acid and salt forms of inositol-tripyrophosphate (ITPP) isomers to shift the P50 value of hemoglobin, thereby improving the rate and efficiency of oxygenation by blood even when red blood cell counts are low. Indications for the new method include anemias and hypoxia arising from infection, chemotherapy, premature birth, altitude change, compromised lung or heart function, aplastic anemia and anemia associated with a myelodysplastic syndrome, and other causes.
