At present, the common treatment for thrombocytopenia is divided into non-drug therapy, such as platelet infusion, and drug therapy, such as thrombopoietin receptor ag-onists (TPO-RAs), recombinant human interleukin-11 (rHuIL-11), and recombinant human thrombopoietin (rHuTPO). Here, TPO is linked to Thrombocytopenia.
