[edit] Mechanism

It works by inhibiting the maturation of megakaryocytes into platelets. The exact mechanism of action is unclear, although it is known to be a potent (IC₅₀ = 36nM) inhibitor of phosphodiesterase-III.

[edit] Uses

According to a 2005 Medical Research Council randomized trial, the combination of hydroxyurea with aspirin is superior to the combination of anagrelide and aspirin for the initial management of ET. The hydroxyurea arm had a lower likelihood of myelofibrosis, arterial thrombosis, and bleeding, but it had a slightly higher rate of venous thrombosis.^[1]

[edit] Side-effects

Common side effects are headache, diarrhea, unusual weakness, nausea and dizziness.
