Gemfibrozil 13-24 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 74-81 16507380-11 2005 CONCLUSIONS: Both IFN and gemfibrozil inhibit the activity of the hepatic enzymes CYP1A2 and CYP2C19. Gemfibrozil 26-37 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 93-100 11602509-8 2001 Gemfibrozil may also impair clearance of CYP2C19 and CYP1A2 substrates, but inhibition of other CYP isoforms is unlikely. Gemfibrozil 0-11 cytochrome P450 family 2 subfamily C member 19 Homo sapiens 41-48
