Used primarily in the treatment of advanced renal cell carcinoma (kidney cancer), hepatocellular carcinoma (liver cancer), and differentiated thyroid carcinoma that is resistant to radioactive iodine. It functions as a multi-kinase inhibitor, blocking several key signaling pathways involved in tumor cell proliferation and angiogenesis. By inhibiting these pathways, it helps slow tumor growth and reduce the formation of new blood vessels that feed tumors. Administered orally, it is often prescribed when other treatment options are no longer effective.
