Product Description
Eltrombopag, an orally administered, small-molecule non-peptide thrombopoietin receptor agonist, selectively binds to the transmembrane domain of the thrombopoietin receptor on the surface of platelets, megakaryocytes and megakaryocyte precursor cells. The drug acts via the Janus Kinase/Signal Transducer and Activator of Transcription (JAK/STAT) pathway to activate megakaryocyte proliferation and differentiation in bone marrow progenitor cells, similar to those observed with endogenous thrombopoietin.
