- Curator reviewed · 5 references
Lusutrombopag mimics the biological actions of endogenous thrombopoietin (TPO) by acting as an agonist for the thrombopoietin receptor (TPOR) expressed on megakaryocytes. It binds to the transmembrane domain of the receptor and induces thrombocytopoiesis by targeting the same signal transduction system as that of endogenous TPO, which involves the activation of JAK and STAT pathways. It stimulates the proliferation and differentiation of bone marrow progenitor cells into megakaryocytes, which undergoes maturation to act as precursor cells for platelets. A single megakaryocyte produces and releases thousands of platelets upon maturation and series of remodeling events. Lusutrombopag displays high specificity towards human TPORs when compared to murine TPORs. Lusutrombopag may affect other hematopoietic lineages as well, including erythroid, granulocytic and lymphoid lineages. One case of increased leukocyte and erythrocyte counts that prolonged for over 120 days was reported following administration in a patient with liver cirrhosis (LC) due to hepatitis C virus.
