Crizotinib is a tyrosine kinase receptor inhibitor that targets Recepteur d’Origine Nantais (RON), hepatocyte growth factor receptor (HGFR, c-MET), and anaplastic lymphoma kinase (ALK).
ALK-positive tumors occur in a small percentage of patients with non-small cell lung cancer (NSCLC). ALK’s fusion with the chimeric protein echinoderm microtubule-associated protein-like 4 (EML4) is a characteristic of most of these cases.
ALK is inhibited by crizotinib through the creation of an inactive protein structure and the inhibition of its phosphorylation. Tumor survival and cell proliferation with this genetic mutation are reduced.

Pregnancy warnings:
Breastfeeding warnings:
Pregnancy Categories:
Category A: Satisfactory and well-controlled studies show no risk to the fetus in the first trimester or the later trimester.
Category B: No evidence shown of risk to the fetus found in animal reproduction studies, and there are not enough studies on pregnant women
Category C: Adverse effects on the fetus found with evidence in animal reproduction studies and no adequate evidence for a result in humans must take care of potential risks in pregnant women
Category D: There is adequate data available with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits
Category X: Drugs listed in this category outweigh risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.
Category N: There is no data available for the drug under this category
In a phase I trial, 50–300 mg of crizotinib were administered daily or twice daily to 37 patients with a range of solid tumor malignancies that were not responding to treatment. Two patients with non-small cell lung cancer (NSCLC) in this cohort responded to treatment after developing mutations in the anaplastic lymphoma kinase (ALK) gene linked to echinoderm microtubule-associated protein-like 4 (EML4).
The two-year overall survival rate was higher for ALK mutation-positive patients treated with crizotinib than for those who did not receive the medication.
It is taken orally in tablet form with or without food.
It should be swallow as whole at time.
Don’t chew or crush the pellets.
Pellets enclosed in a shell should not be swallowed.
After 6 hours, skip the missing dose and don’t take two doses to make up for it.
Do not take an additional dose if you vomited after taking it; instead, take it at the appointed time.
Patient information leaflet
Generic Name: crizotinib
Why do we use crizotinib?
A kinase inhibitor called crizotinib is prescribed to patients with metastatic non-small cell lung cancer (NSCLC) whose tumors test positive for ROS1 or anaplastic lymphoma kinase (ALK) according to an FDA-approved test.
In pediatric patients aged 1 year and up, as well as young adults, crizotinib is also recommended for the treatment of recurrent or refractory systemic anaplastic large cell lymphoma (ALCL).
Patients aged one year and up who have an inflammatory myofibroblastic tumor (IMT) that is unresectable, recurrent, or resistant may be treated with crizotinib.
