150mg Ceritinib Capsules are medication used in cancer treatment, specifically for the management of a type of lung cancer called non-small cell lung cancer (NSCLC). It is an oral tyrosine kinase inhibitor (TKI) that targets specific proteins involved in the growth and spread of cancer cells. Ceritinib is approved for the treatment of NSCLC that has a specific genetic mutation known as anaplastic lymphoma kinase (ALK) gene rearrangement. This mutation causes the ALK protein to be abnormally active, leading to uncontrolled cell growth and cancer development. 150mg Ceritinib Capsules works by blocking the activity of the abnormal ALK protein, thereby inhibiting the growth and proliferation of cancer cells harboring the ALK gene rearrangement.
