🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine is a multikinase inhibitor that targets multiple protein kinases involved in tumor growth, angiogenesis, and the tumor microenvironment. It inhibits kinases such as VEGFR1, VEGFR2, VEGFR3, TIE2, PDGFR, FGFR, KIT, RET, RAF-1, BRAF, and BRAF V600E. By blocking these kinases, it interferes with signaling pathways that promote cancer cell proliferation, survival, and the formation of new blood vessels that supply the tumor. This dual action helps to slow tumor growth and progression.
