  ►    Mechanism of Drug Drug Interaction :  Sorafenib is metabolised by the cytochrome P450 isoenzyme CYP3A4. Rifampicin can reduce exposure to sorafenib. Other inducers of this enzyme (such as carbamazepine, dexamethasone, St John’s wort, phenobarbital, and phenytoin) may also reduce blood concentrations of sorafenib. However, ketoconazole did not alter exposure to sorafenib and other drugs that inhibit CYP3A4 are considered unlikely to alter the metabolism of sorafenib. In vitro studies have indicated that sorafenib itself inhibits the cytochrome P450 isoenzymes CYP3A4, CYP2C19, and CYP2D6, but use of sorafenib with midazolam, or omeprazole, or dextromethorphan did not alter the exposure to any of these drugs; interactions with drugs that are substrates of these enzymes are considered unlikely. Sorafenib inhibits the cytochrome P450 isoenzyme CYP2C9 in vitro, and may increase concentrations of its substrates. Elevated INR and bleeding events have been reported with the use of sorafenib and warfarin. Sorafenib also inhibits the isoenzymes CYP2B6 and CYP2C8 in vitro, and drug interactions with substrates of these may occur. Sorafenib may increase exposure to docetaxel, doxorubicin, and irinotecan; variable effects on fluorouracil have been reported. .
