Medication Summary

Platelet inhibition is helpful in patients with thrombocytosis. Aspirin is most often used, but anagrelide may also be effective. [52] The optimal pharmacologic therapy in primary erythromelalgia is still unknown.


Nonsteroidal Anti-inflammatory Drugs (NSAIDs)

Class Summary

Aspirin is preferred because it provides relief lasting longer than that of indomethacin or other nonsteroidal anti-inflammatory drugs (NSAIDs), presumably because of irreversible platelet inhibition.


Aspirin inhibits prostaglandin synthesis, which prevents formation of platelet-aggregating thromboxane A2.

Anagrelide (Agrylin)

Anagrelide may inhibit cyclic nucleotide phosphodiesterase and the release of arachidonic acid from phospholipase possibly by inhibiting phospholipase A2. A decrease in megakaryocyte hypermaturation may result in a reduction in platelet production.
