In patients with reduced platelet count in clinical practice, it is often necessary to apply drugs that increase platelets. There are two major categories of drugs that increase platelets, namely oral drugs and drugs for injection. Oral medications commonly include platelet-raising capsules, which is a proprietary Chinese medicine that can stimulate the proliferation of megakaryocytes in the bone marrow, causing an increase in platelet count. There is also amineptin, a small molecule protein extracted from pig hoof nails, which can also increase platelet count. Drugs for platelet increase by injection, commonly used are recombinant human thrombopoietin. This is a cytokine that specifically binds to receptors on megakaryocytes to promote the proliferation and division of megakaryocytes to produce more platelets to increase the number of platelets in peripheral blood, and can be used clinically for various causes of thrombocytopenia. In addition, interleukin-11 is also used in the treatment of thrombocytopenia, especially in patients with malignant tumors who have reduced platelet counts after chemotherapy.
