Voriconazole is the preferred antifungal agent forAspergillus infections. Therapeutic drug monitoring is recommended to achieve target concentrations and prevent toxicity. However, variable pharmacokinetics, cytochrome P450 polymorphisms, and extensive drug-drug interactions can contribute to subtherapeutic concentrations. We report a voriconazole “boosting” effect of omeprazole to achieve target concentrations for the treatment ofAspergillus in a patient who had persistently subtherapeutic trough concentrations.
