- Anaplastic Large Cell Lymphoma (ALCL): For systemic ALCL in adults and children aged 1 year and older.
- Inflammatory Myofibroblastic Tumor (IMT): For patients with IMT, a rare tumor that can occur in various organs.
Dosage and Administration
- Adults: 250 mg orally twice daily.Pediatric Patients (ALCL): Dosing is based on body surface area (BSA), typically 280 mg/m² twice daily.
- Administration Guidelines: Take with or without food.

Serious side effects may include:
- Liver Toxicity: Elevations in liver enzymes; monitor liver function regularly.
- Pneumonitis or interstitial lung disease are pulmonary problems that can cause coughing and dyspnea.
- Heart Issues: Bradycardia (slow heart rate), QT prolongation.
Storage

- Do not use expired medication.
Benefits
- Efficacy: Demonstrated significant tumor shrinkage in ALK-positive NSCLC patients.
- Convenience: Intravenous treatments are no longer necessary when taken orally.
- Targeted Action: Specifically inhibits ALK, leading to reduced cancer cell proliferation.
- Quality of Life: Patients often experience fewer side effects compared to traditional chemotherapy.
Prescription Considerations
- Contraindications: Known hypersensitivity to crizotinib.
- Availability: Crizotinib is a prescription medication and should be used under the supervision of a qualified healthcare provider.

Drug Interactions
- CYP3A Inhibitors: Concomitant use may increase crizotinib levels; consider dose adjustments.
- CYP3A Inducers: May decrease crizotinib efficacy; avoid concomitant use if possible.
- QT-Prolonging Agents: Use with caution due to potential additive effects.
- Bradycardia-Inducing Drugs: Monitor heart rate closely.
