11. Mechanism of Action

11.1 Pharmacodynamics

Sorafenib is a multikinase inhibitor that reduces tumor cell proliferation in vitro by inhibiting intracellular kinases (c-CRAF, BRAF, and mutant BRAF) and cell surface kinases (KIT, FLT-3, RET, RET/PTC, VEGFR-1, VEGFR-2, VEGFR-3, and PDGFR-ß). [2]

11.2 Pharmacokinetics

• Absorption: Plasma sorafenib concentrations peak within 3 hours.
• Distribution: Sorafenib binds to plasma proteins at up to 99.5%.
• Metabolism: Sorafenib undergoes oxidative metabolism in the liver via CYP3A4 and glucuronidation via UGT1A9.
• Excretion: Following a 100mg oral solution dose, 96% of the dose was recovered within 14 days, with 77% excreted via feces and 19% via urine mainly as glucuronidated metabolites. Unchanged sorafenib was found in feces but not in urine (51%).

• The tablet form masks the drug’s taste, making it easier to swallow.
