Grara stands as a powerful oxygenation enhancer in the fields of tissue oxygenation. 
 
Grara increases oxygen release to tissues: 2 to 3 times more than normal red cells during extended period (up to one month due to long circulating action of red cells).
 
Grara is designed to be used notably in sickle cell disease. 
 
Sickle Cell Disease
 
Mixed with Grara which delivers oxygen to hypoxic cells, human sickle red cells immediately recover their normal shape.
 
Grara is designed to divide red cell transfusions by 5 and to prevent crisis. 
 
  
Grara is in preclinical studies.
