There are two types of platelet-elevating injections commonly used in clinical practice: one is recombinant human platelet thrombopoietin, which costs about RMB 1050 for one daily subcutaneous injection and is often used in patients with various causes of thrombocytopenia, such as leukemia patients with thrombocytopenia after chemotherapy, and immune thrombocytopenia patients, which can be treated with recombinant human platelet thrombopoietin. Another commonly used platelet-elevating injection is interleukin-11, which can specifically bind to megakaryocytes in bone marrow, promote the proliferation and division of megakaryocytes, produce more platelets, and increase the number of platelets in peripheral blood, thus achieving the purpose of hemostasis. These are the two commonly used clinically to raise platelet injections, recombinant human thrombopoietin is more expensive, about 1050 yuan a, interleukin-11 price is cheaper, a in about 160 yuan.
