NCIt definition : The hydrochloride salt of a synthetic quinazoline derivative, Anagrelide Hydrochloride
reduces platelet production through a decrease in megakaryocyte maturation. Anagrelide
inhibits cyclic AMP phosphodiesterase, as well as ADP- and collagen-induced platelet
aggregation. At therapeutic doses, it does not influence white cell counts or coagulation
parameters. Anagrelide is used for treatment of essential thrombocythemia to reduce
elevated platelet counts and the risk of thrombosis. (NCI04);
