Interactions Being metabolized by hepatic cytochrome P450, voriconazole interacts with many drugs. Voriconazole should not be used in conjunction with many drugs (including sirolimus, rifampicin, rifabutin, carbamazepine, quinidine and ergot alkaloids) and dose adjustments and/or monitoring should be done when coadministered with others (including fluconazole, warfarin, ciclosporin, tacrolimus, omeprazole, and phenytoin). Voriconazole may be safely administered with cimetidine, ranitidine, indinavir, macrolide antibiotics, mycophenolate, digoxin and prednisolone. Pharmacology Pharmacokinetics Voriconazole is well absorbed orally with a bioavailability of 96%, allowing patients to be switched between intravenous and oral administration.

A generic version of the tablet form of voriconazole was introduced in the US in 2011 after Pfizer and Mylan settled litigation under the Hatch-Waxman Act; a generic version of the injectable form was introduced in 2012.
