RESULTS: The CYP2C8 inhibitor gemfibrozil increased the AUC(0, ) of montelukast 4.3-fold and its t(1/2) 2.1-fold (P < 0.001). montelukast 25-36 cytochrome P450 family 2 subfamily C member 8 Homo sapiens 125-131 21838784-5 2012 Plasma concentrations of montelukast, gemfibrozil, itraconazole and their metabolites were measured up to 72 h. RESULTS: The CYP2C8 inhibitor gemfibrozil increased the AUC(0, ) of montelukast 4.3-fold and its t(1/2) 2.1-fold (P < 0.001). montelukast 180-191 cytochrome P450 family 2 subfamily C member 8 Homo sapiens 125-131 21838784-9 2012 CONCLUSIONS: CYP2C8 is the dominant enzyme in the biotransformation of montelukast in humans, accounting for about 80% of its metabolism. montelukast 71-82 cytochrome P450 family 2 subfamily C member 8 Homo sapiens 13-19 21838784-11 2012 Montelukast may serve as a safe and useful CYP2C8 probe drug. montelukast 0-11 cytochrome P450 family 2 subfamily C member 8 Homo sapiens 43-49
