Mechanism & Pharmacology

Understanding how voriconazole works can empower patients dealing with fungal infections. This antifungal medication primarily targets and inhibits the growth of fungi, effectively stopping their spread.

Simplified explanation

Voriconazole works by disrupting the production of ergosterol, a vital component in the cell membranes of fungi. By breaking down these membranes, it inhibits fungal growth, allowing the body’s immune system to fight off the infection. It’s like cutting off the fuel supply to a fire—it prevents the infection from spreading and helps eliminate it from the body.

Clinical terms

Understanding some clinical terms related to voriconazole can be beneficial:

• Fungicidal activity: This refers to a drug's ability to kill fungi directly.
