The mechanism of action and common side effects of axitinib

Axitinib/Axitinib (Axitinib) is a targeted therapy drug mainly used to treat patients with advanced renal cell carcinoma (RCC). Its mechanism of action is mainly by inhibiting the vascular endothelial growth factor receptor (VEGFR), blocking tumor angiogenesis, thereby reducing the blood supply and nutrient supply to the tumor, thereby inhibiting the growth and spread of the tumor. VEGFR plays an important role in tumor angiogenesis and is one of the key factors in tumor cell proliferation and metastasis. By binding to VEGFR and inhibiting its activation, axitinib can significantly inhibit tumor angiogenesis and prevent tumor growth and metastasis.

In addition, axitinib also has certain anti-tumor activity. Studies have shown that it has an ideal effect on multiple tumor types, including advanced renal cancer, non-small cell lung cancer, and gastrointestinal stromal tumors. The mechanism of axitinib is to inhibit angiogenesis in the tumor microenvironment and reduce the blood supply to the tumor, directly leading to tumor shrinkage or shrinkage. Compared with other targeted drugs, axitinib has a significant inhibitory effect on the microvascular environment of tumors, making it a very effective choice in the treatment of cancers such as renal cell carcinoma and lung cancer.

However, although axitinib has significant efficacy in patients with advanced renal cancer, common side effects during use cannot be ignored. The most common side effects include high blood pressure, diarrhea, fatigue, loss of appetite, and rash. Because axitinib inhibits VEGFR, it may affect normal blood vessel function and lead to the occurrence of hypertension. In addition, drugs may affect the kidneys, heart, and digestive system, causing adverse reactions such as renal damage, edema, and bleeding. Some patients may experience mild nausea or vomiting early in treatment. Although these side effects are usually not serious, patients' health needs to be monitored regularly.

Axitinib's effects on blood vessels may also lead to serious complications such as bleeding and blood clots. While using axitinib, patients should undergo regular blood tests, especially monitoring of platelet count and liver and kidney function, to prevent possible side effects.
