This drug has been widely praised by oncologists and patients alike for its effectiveness at slowing down or stopping the growth of tumors. In this article, we will provide you with extensive information on Xalkori, including its uses, dosage, demographic, side effects, interactions, and generic options. What is Xalkori? Xalkori, also known as Crizotinib, is a kinase inhibitor drug that was approved by the US FDA in 2011. It is used to treat certain types of non-small cell lung cancer (NSCLC) and anaplastic lymphoma kinase (ALK) positive metastatic NSCLC. It is only prescribed for individuals who have genetic mutations, including ALK and ROS1 rearrangements in their tumor. Uses of Xalkori Xalkori is an effective drug for treating different types of cancer in individuals who have specific genetic mutations. The drug blocks the signals sent by the proteins that promote the growth and division of cancer cells. By inhibiting the effect of these signals, Xalkori slows down the growth and spread of cancer cells.
