Summary
High voriconazole concentrations can cause toxicity in patients with invasive aspergillosis. Monitoring plasma levels may help optimize voriconazole dosing for better patient outcomes.
Area of Science:
- Medical Mycology
- Clinical Pharmacology
Background:
- Voriconazole is a key antifungal medication for invasive aspergillosis.
- Significant interpatient variability exists in voriconazole plasma concentrations.
Observation:
- Three patients experienced diverse toxicities, including neurological and metabolic disturbances.
- These adverse events were potentially linked to elevated voriconazole levels.
Findings:
- High voriconazole plasma concentrations are associated with serious adverse events.
- Toxicity manifestations were varied, impacting multiple organ systems.
Implications:
- Therapeutic drug monitoring of voriconazole is crucial.
- Optimizing voriconazole dosage can mitigate toxicity and improve treatment efficacy.
