Cytochrome P₄₅₀2C8 (abbreviated CYP2C8), a member of the cytochrome P450 mixed-function oxidase system, is involved in the metabolism of xenobiotics in the body.

CYP2C8 Ligands

Following is a table of selected substrates, inducers and inhibitors of 2C8.

Inhibitors of CYP2C8 can be classified by their potency, such as:

• Strong inhibitor being one that causes at least a 5-fold increase in the plasma AUC values, or more than 80% decrease in clearance.
• Moderate inhibitor being one that causes at least a 2-fold increase in the plasma AUC values, or 50-80% decrease in clearance.
• Weak inhibitor being one that causes at least a 1.25-fold but less than 2-fold increase in the plasma AUC values, or 20-50% decrease in clearance.

Selected inducers, inhibitors and substrates of CYP2C8

Substrates	Inhibitors	Inducers
amodiaquine (antimalarial, anti-inflammatory) cerivastatin (statin) paclitaxel (chemotherapeutic) repaglinide (antidiabetic) torasemide (loop diuretic) sorafenib (tyrosine kinase inhibitor) rosiglitazone (antidiabetic) - converted to active metabolites	Strong: gemfibrozil (hypolipidemic) Moderate trimethoprim (antibiotic) Unspecified potency thiazolidinediones (antidiabetic) montelukast (leukotriene receptor antagonist) quercetin (antiinflammatory)	rifampicin (antibiotic)

Where classes of agents are listed, there may be exceptions within the class.
