Sorafenib is a targeted cancer medicine taken as a tablet. It is used for liver cancer (hepatocellular carcinoma) that cannot be removed by surgery, for advanced kidney cancer (renal cell carcinoma), and for thyroid cancer that has stopped responding to radioactive iodine.
It blocks two things at once: signals inside the cancer cell that tell it to grow (through the RAF pathway) and signals that make new blood vessels grow towards the tumour (through VEGFR and PDGFR). It was one of the first medicines of this kind and is now available as generics from licensed manufacturers.
Sorafenib is taken twice a day, continuously, without food. Hand-foot skin reaction, diarrhoea, tiredness and raised blood pressure are the common side effects and are usually managed by adjusting the dose. It is a prescription-only medicine; a valid prescription must be provided at checkout.
