[Research Advances in the Treatment of Eltrombopag for Adult Patients with Primary Immune Thrombocytopenia--Review].

Primary immune thrombocytopenia (ITP) is an autoimmune disease characterized by thrombocytopenia, and T cell immune dysfunction plays an important role in the formation of ITP. As a thrombopoietin receptor agonist (TPO- RA), eltrombopag can not only directly stimulate megakaryocytes to produce platelets, but also play an immunomodulatory role by inducing regulatory T cell generation and reducing proinflammatory factors. As a second-line treatment drug for adult ITP, eltrombopag is increasingly widely used in clinical practice. This review summarized the latest research progress on the mechanism of action, efficacy, safety, and how to reduce the dosage of eltrombopag in ITP.
