Sorafenib is a kinase inhibitor acting as an antineoplastic agent used to treat advanced renal cell and liver cancer.
Sorafenib is a targeted cancer medication that belongs to the class of kinase inhibitors. It works by interfering with signals that help cancer cells grow and spread. You will find sorafenib in the branded product Nexavar, which is available in Hong Kong.
In Hong Kong, the primary product containing sorafenib is Nexavar. Nexavar is supplied as oral tablets, typically in 200 mg strength, and is marketed by a multinational pharmaceutical company. Both the branded tablets and the generic sorafenib tablets (where available) contain the same active ingredient, though the brand name is the most widely recognised. The medication is prescribed by specialists and dispensed through hospitals and registered pharmacies under the oversight of the Hong Kong Department of Health.

By disrupting these pathways, the drug can slow tumour growth and reduce the supply of nutrients to the tumour. The effect usually begins within a few weeks of starting treatment, although the exact timing can differ from person to person.
Most people notice mild, short-lasting reactions, such as:
