Ruxolitinib is a prescription medication that belongs to a class of drugs known as Janus kinase (JAK) inhibitors. It is approved by the U.S. Food and Drug Administration (FDA) for the treatment of certain types of blood disorders and certain types of cancer.
In the treatment of blood disorders, ruxolitinib is used to treat myelofibrosis, a rare type of bone marrow cancer that results in scarring of the bone marrow and abnormal production of blood cells. It is also used to treat polycythemia vera, a blood disorder characterized by the production of too many red blood cells. Ruxolitinib works by inhibiting the activity of JAK enzymes, which play a role in the development and progression of these blood disorders.
In the treatment of cancer, ruxolitinib is used to treat mantle cell lymphoma, a type of non-Hodgkin's lymphoma. It is also being studied in the treatment of other types of cancer, including breast cancer, pancreatic cancer, and prostate cancer.
