Xalkori Dosage Insights: A Comprehensive Guide

Introduction

Xalkori is an important medication prescribed for specific types of cancer. If you have been diagnosed with certain cancers, your healthcare provider may recommend Xalkori as part of your treatment plan.

This prescription medication is primarily indicated for:

• Non-small cell lung cancer (NSCLC) characterized by:
  • An abnormality in the anaplastic lymphoma kinase (ALK) gene
  • Metastasis to other regions of the body
• NSCLC associated with:
  • A defect in the ROS1 gene
  • Spread beyond the lungs

For some pediatric patients, Xalkori is used to treat:

• Systemic anaplastic large cell lymphoma (ALCL), specifically when:
  • It results from an aberration in the ALK gene
  • It has either relapsed after treatment or has not responded to other therapies

The active compound in Xalkori is crizotinib, which is responsible for its therapeutic effects. This medication is available in capsule form and falls under the category of kinase inhibitors. This article will delve into the recommended dosages, potency, and administration details of Xalkori.
