Monitoring and Testing:
You will be monitored carefully and regularly by your doctor while you are taking anagrelide. Before beginning this therapy and during treatment, your

side effects early on and to assess your response to the medicine.
How Anagrelide Works:
Thrombocythemia is a blood disorder in which there are too many platelets found in the blood. The megakaryocyte is the cell type from which platelets are
produced. It is in the mature stage of the megakaryocyte's development that platelets are formed. If this maturation process is stopped platelets are
unable to be produced.
Anagrelide interferes with the megakaryocyte maturation. It does this by blocking an enzyme (phospholipase A2) which is needed for completing the
maturation process of megakaryocytes.
