How this drug 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.
