Neem Overview
Vemurafenib Overview
-
Vemurafenib is used to treat certain types of melanoma (a type of skin cancer) that cannot be treated with surgery or that has spread to other parts of the body. It is also used to treat a certain type of Erdheim-Chester disease (ECD; a disease that causes an overproduction of a type of white blood cells). Vemurafenib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells.
