Abstract:
Voriconazole is a new antifungal agent effective in the treatment of invasive aspergillosis. Interpatient variation in plasma concentrations is considerable--more than 100-fold. We describe 3 patients with diverse manifestations of toxicity (e.g., hallucinations, hypoglycemia, electrolyte disturbance, and pneumonitis) possibly attributable to high voriconazole concentrations. Measurement of plasma concentrations could be helpful in optimizing voriconazole dosages.
Insights
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.
