Drug Mode of Action ::
Voriconazole is a triazole antifungal agent which inhibits cytochrome P450-dependent enzymes thereby inhibiting ergosterol synthesis in fungal cell membranes. It has a broad spectrum of activity against all Candida spp. including strains resistant to fluconazole), Aspergillus spp., Scedosporium spp., and Fusarium spp.
Drug Interactions ::
Increased prothrombin time w/ oral anticoagulants. May increase plasma concentrations of ciclosporin and tacrolimus, long-acting opiates (e.g. oxycodone, methadone), NSAIDs (e.g. ibuprofen, diclofenac), omeprazole, short-acting opiates (e.g. alfentanil, fentanyl). Decreased voriconazole plasma concentration and increased phenytoin plasma concentrations when used concomitantly. May increase plasma concentration w/ oral contraceptives. Potentially Fatal: May increase risk of QT prolongation or torsades de pointes w/ astemizole, cisapride, pimozide, quinidine and terfenadine. May increase risk of ergotism w/ ergot alkaloids (e.g. ergotamine and dihydroergotamine). May significantly increase plasma concentrations of sirolimus. Decreased plasma concentrations w/ rifampicin, carbamazepine, long-acting barbiturates (e.g. phenobarbital, mephobarbital), efavirenz (?400 mg once daily), ritonavir (?400 mg bid). Concomitant use may significantly increase rifabutin and decrease voriconazole plasma concentration.
