Crizalk 250mg Capsule contains Crizotinib, an antineoplastic medicine belonging to the class of tyrosine kinase inhibitors. It is primarily prescribed for patients with ALK-positive non-small cell lung cancer (NSCLC) that is locally advanced or has spread to other parts of the body. This targeted therapy works by blocking abnormal proteins that promote cancer cell growth, helping slow disease progression and improve treatment outcomes. Crizalk is used only under the supervision of an oncologist and is not recommended for children or adolescents below 18 years of age.
Before starting treatment, patients should inform their doctor about any history of heart, liver, kidney, or stomach disorders. Special precautions are required for patients with vision problems, abnormal ECG results, or low blood cell counts. Proper sun protection is advised during treatment due to increased sensitivity to sunlight.
Crizalk 250mg Capsule is used for the treatment of:
Crizalk 250mg Capsule works by inhibiting the activity of the ALK (anaplastic lymphoma kinase) protein, which is abnormally active in certain lung cancers. By blocking this protein, Crizotinib prevents cancer cells from multiplying and spreading. This targeted mechanism helps slow tumor growth while limiting damage to healthy cells, making it an effective option for ALK-positive NSCLC.

Yes. Crizalk is effective only in patients whose tumors test positive for the ALK gene rearrangement. Molecular or genetic testing is essential before initiating treatment to ensure the medicine will be effective.
Crizalk may be used for long-term treatment as long as it remains effective and well tolerated. Regular monitoring, including blood counts, liver function tests, ECGs, and eye examinations, is required to ensure safety during ongoing therapy.
Crizalk can increase sensitivity to sunlight, raising the risk of sunburn. Patients should use sunscreen, wear protective clothing, and avoid prolonged sun exposure while receiving treatment.
