Sorabenz 200mg Tablet is used in the treatment of the following: 

• Advanced renal cell carcinoma
• Advanced hepatocellular carcinoma
• Differentiated  thyroid carcinoma

Sorabenz 200mg Tablet works by inhibiting multiple protein kinases involved in tumour cell proliferation and angiogenesis (the formation of new blood vessels that supply tumours). Specifically, it targets receptors for vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), and Raf kinases, which play key roles in cancer development and progression.  This stops the growth and spread of the tumour cells to other organs, as well as the formation of blood vessels in the tumour cells.
