Crizotinib

Crizotinib is an anti-cancer medication classified as a tyrosine kinase inhibitor. It is mainly used to treat non-small cell lung cancer (NSCLC) in patients with specific genetic mutations such as ALK (anaplastic lymphoma kinase) or ROS1. By blocking the activity of these abnormal proteins, Crizotinib helps slow down or stop the growth of cancer cells, thereby improving patient outcomes and quality of life.

Uses of Crizotinib

• Treatment of ALK-positive non-small cell lung cancer (NSCLC)
• Treatment of ROS1-positive NSCLC
• Helps control tumor growth and spread

How Crizotinib Works

Crizotinib works by inhibiting tyrosine kinases like ALK and ROS1, which are involved in cancer cell growth. Blocking these enzymes disrupts cancer cell signaling, leading to slowed growth or death of cancer cells.

Benefits of Crizotinib

• Targets specific cancer mutations for effective treatment
• Slows or stops tumor growth
• Can reduce cancer symptoms and improve life quality
• May delay the progression of lung cancer
