NCIt definition : An orally available thrombopoietin (TPO) receptor (TPOR; MPL) agonist, with potential
megakaryopoiesis stimulating activity. Upon administration, lusutrombopag binds to
and interacts with the transmembrane domain of human TPO receptor expressed on megakaryocytes,
which leads to the proliferation and differentiation of megakaryocytic progenitor
cells from hematopoietic stem cells. This increases the production of platelets and
may prevent or treat thrombocytopenia in patients with chronic liver disease. TPOR
is a cytokine receptor and member of the hematopoietic receptor superfamily.;
