What is this medication?

Voriconazole, Vfend
Antifungal, Azole Derivative

Voriconazole, Vfend is indicated for treatment of fungal infections.

How does this medication work? 

Voriconazole, Vfend inhibits ergosterol synthesis via action on cytochrome P450 activity, resulting in interfered fungal cell membrane formation.

How should I take this medication? 

Oral: 200 to 300 mg twice daily or weight-based dosing (3 to 4 mg/kg twice daily) 

Therapeutic drug monitoring: Adjust dose based on serum trough concentration to ensure efficacy and avoid toxicity. Timing and frequency of concentration monitoring is individualized

How to Take: Infuse over 1 to 3 hours (rate not to exceed 3 mg/kg/hour). May be infused simultaneously with nonconcentrated electrolytes or TPN through a separate IV line. If TPN is infused through a multiple lumen catheter, use a different port than used for voriconazole.  For oral use, administer 1 hour before or 1 hour after a meal. Shake oral suspension for approximately 10 seconds before each use. Enteral tube feedings may decrease oral absorption; may hold tube feedings for 1 hour before and 1 hour after a voriconazole dose.
