Where is Sorafenib used?

Sorafenib is used for the treatment of advanced renal cell carcinoma which is a type of cancer that begins in the kidneys. This can also be used in hepatocellular carcinoma which is a type of liver cancer. This medication is used if cancer cannot be treated with surgery and radioactive iodine. Sorafenib is in the class of medications known as multi-kinase inhibitors that block the action of an abnormal protein that signals cancer cells to multiply. The Food and Drug Administration (FDA) has already approved this prescription for oral use.

How does Sorafenib work?

Sorafenib works by stopping the action of several kinase enzymes. This stops the signals that tell the cancer cells to develop and increase. It also stops blood vessels from growing into the tumor. This decreases the tumor’s blood supply and along with it is the supply of oxygen and nutrients. Both these effects stop the tumor from growing.

The approach that cells in the body works and develops is controlled by countless enzymes called kinases. In cancerous cells, these kinases make the cells develop abnormally and stimulate near blood vessels to progress into the tumor. The new blood vessels let the cancer cells grow and multiply by supplying them with oxygen and nutrients. They also permit the cancerous cells to spread into other areas of the body through blood circulation.
