Pharmacology

Indication

Used in kidney cell cancer and investigated for use/treatment in pancreatic and thyroid cancer.

Associated Conditions
Pharmacodynamics

Axitinib prevents the progression of cancer by inhibiting angiogenesis and blocking tumor growth.

Mechanism of action

Axitinib selectively blocks the tyrosine kinase receptors VEGFR-1 (vascular endothelial growth factor receptor), VEGFR-2, and VEGFR-3.

Absorption

After one 5 mg dose of axitinib, it takes about 2.5 to 4.1 hours to reach maximum plasma concentration.

Volume of distribution

The volume of distribution is 160 L.

Protein binding

Plasma protein binding for axitinib is high at over 99% with most protein binding to albumin followed by α1-acid glycoprotein.

Metabolism

Axitinib undergoes mainly hepatic metabolism. CYP3A4 and CYP3A5 are the main hepatic enzymes while CYP1A2, CYP2C19, and UGT1A1 enzymes are secondary.

Route of elimination

Axitinib is mainly eliminated unchanged in the feces (41%) with 12% of the original dose as unchanged axitinib. There is also 23% eliminated in the urine, most of which are metabolites.

Half life

Axitinib has a half life of 2.5 to 6.1 hours.

Clearance

The average clearance of axitinib is 38 L/h.

Toxicity

Some of the more serious toxic effects seen in patients taking axitinib include, but are not limited to, hypertension, thrombotic events, hemorrhage, and GI perforation.

Affected organisms
  • Humans and other mammals

Food Interactions
  • Avoid combination with strong CYP3A4 inhibitors such as grapefruit juice due to the likely increased levels of axitinib. If the combination cannot be avoided, reduce axitinib dose by 50%.
  • Axitinib can be taken with or without food.
