If you or someone you know has been diagnosed with non-small cell lung cancer, you may have heard of crizotinib, which is sold under the brand name Xalkori. Crizotinib is an oral kinase inhibitor that is used to treat metastatic non-small cell lung cancer that is caused by a defect in either a gene called anaplastic lymphoma kinase (ALK) or a gene called ROS1. It is also used to treat other conditions such as anaplastic large cell lymphoma and inflammatory myofibroblastic tumor.
Crizotinib blocks certain proteins in cancer cells, which can slow or stop the growth of the cancer. It is available in the form of oral capsules or pellets and is taken twice daily. As with any medication, there are potential side effects to consider, but your doctor will work with you to determine if crizotinib is the right treatment option for you.

Crizotinib Overview
If you or a loved one has been diagnosed with non-small cell lung cancer (NSCLC) or anaplastic large cell lymphoma (ALCL), you may have heard of crizotinib. Crizotinib is a medication that is used to treat these types of cancer, and it has been found to be effective in many cases.
Brand Name and Availability
Crizotinib is sold under the brand name Xalkori. It is available in capsule form for oral administration. Xalkori is a prescription medication that can only be obtained with a healthcare provider’s prescription.
Medical Uses and Efficacy
Crizotinib is a tyrosine kinase inhibitor that works by blocking the activity of a protein called anaplastic lymphoma kinase (ALK) and another protein called c-ros oncogene 1 (ROS1). These proteins are involved in the growth and spread of cancer cells. By blocking their activity, crizotinib can slow down or stop the growth of cancer cells.
Crizotinib has been found to be effective in treating NSCLC and ALCL that have a specific genetic mutation. It has been approved by the FDA and the EMA for the treatment of these types of cancer.
Dosage and Administration
The dosage of crizotinib will depend on a number of factors, including the patient’s age, weight, and overall health, as well as the type and stage of cancer being treated. It is important to follow your healthcare provider’s instructions carefully when taking crizotinib.
Crizotinib is taken orally in capsule form. It is usually taken twice a day, with or without food. The capsules should be swallowed whole and not crushed or opened.
If you are prescribed crizotinib, it is important to take it exactly as directed by your healthcare provider. Do not stop taking the medication without first consulting your healthcare provider.
In summary, crizotinib is a systemic medication that has been found to be effective in treating certain types of cancer, including NSCLC and ALCL. It is sold under the brand name Xalkori and is available in capsule form for oral administration. If you are prescribed crizotinib, it is important to follow your healthcare provider’s instructions carefully and take the medication exactly as directed.
Safety and Side Effects
Crizotinib is a kinase inhibitor drug used to treat non-small cell lung cancer. It is important to note that like any medication, crizotinib has side effects. It is crucial to discuss with your healthcare provider the benefits and risks of taking this medication.
Common Adverse Reactions
Common side effects of crizotinib include nausea, vomiting, diarrhea, constipation, decreased appetite, headache, dizziness, itching, and rash. These side effects can be managed with antiemetics and other medications. It is important to contact your healthcare provider if these side effects become severe or persistent.
Serious Concerns and Precautions
Crizotinib can cause serious side effects such as bradycardia, visual loss, and congenital long QT syndrome. Patients with a history of heart problems should be closely monitored while taking crizotinib. It is also important to inform your healthcare provider if you are pregnant, planning to become pregnant, or breastfeeding.
Managing Overdose and Interactions
In the case of an overdose, seek immediate medical attention. Crizotinib can interact with grapefruit and other medications that are metabolized by the CYP3A4 enzyme. It is important to inform your healthcare provider of all medications and supplements you are taking.
In conclusion, crizotinib is an effective medication used to treat non-small cell lung cancer. While it has side effects and serious concerns, it is important to discuss with your healthcare provider the benefits and risks of taking this medication. By following your healthcare provider’s instructions and informing them of any concerns or side effects, you can safely and effectively manage your treatment.
