Crizotinib is a medication used in the treatment of certain types of cancers, such as non-small cell lung cancer. It belongs to a class of drugs called tyrosine kinase inhibitors. Crizotinib works by blocking a protein found in some cancer cells, which helps to stop the growth and spread of cancer cells. Crizotinib is taken orally, typically twice daily. Common side effects include nausea, vomiting, diarrhea, liver problems, and vision changes.
Crizotinib, sold under the brand name Xalkori, is a prescription medication used to treat specific types of cancer. Here's a breakdown of its key aspects:
What Cancers Does it Treat?
- Non-small cell lung cancer (NSCLC): This medication targets ALK-positive or ROS1-positive NSCLC, meaning the cancer cells have specific genetic alterations involving these genes.
- Anaplastic large cell lymphoma (ALCL): Crizotinib is used for ALK-positive ALCL that has either returned after previous treatment or hasn't responded to other therapies.
- Inflammatory myofibroblastic tumor (IMT): This medication can treat unresectable (cannot be removed surgically) or progressive (worsening) IMT in adults and children.
How Does it Work?
Crizotinib belongs to a class of drugs called tyrosine kinase inhibitors (TKIs). It works by blocking the activity of specific enzymes called ALK and ROS1. These enzymes play a crucial role in the growth and spread of cancer cells. By inhibiting these enzymes, crizotinib helps to slow or stop the growth of cancer cells.
