Crizotinib (Xalkori®)

Crizotinib

Brand Name: Xalkori®

Crizotinib is used in the treatment of certain types of lung cancer.

Crizotinib is a type of tyrosine kinase inhibitor. Kinases are enzymes that are involved in many functions, including cell growth and reproduction. Crizotinib blocks the anaplastic lymphoma kinase (ALK) and also the c-MET/hepatocyte growth factor receptor. This action disrupts certain pathways in the cell, which can prevent the growth of tumor cells. Crizotinib is made especially for the treatment of a type of lung cancer in which ALK is overactive due to an abnormality in the ALK gene.

This medication is given as a hard gelatin capsule taken by mouth. Usually, crizotinib is taken twice daily. Capsules can be taken with or without food, and should be swallowed whole (not crushed, chewed, or split). The duration of treatment depends on several factors, including how well the cancer is responding to the drug. Your doctor will determine the approach that is best for you.

Crizotinib side effects

To prevent problematic interactions between crizotinib and other drugs, be sure to tell your doctor if you are allergic to any medications, and what other medications and supplements you are currently taking. You should also inform your doctor if you have or ever had liver tumor, liver disease, kidney disease, a heart rhythm disorder, a personal or family history of Long QT syndrome, or an electrolyte imbalance. Crizotinib should not be taken if you are pregnant. Be sure to inform your doctor if you are pregnant before beginning treatment, or if you become pregnant during treatment. Women should not breastfeed while taking crizotinib.
