Echinocandins

Definition

Echinocandins are a class of antifungal drugs that inhibit the synthesis of β-(1,3)-D-glucan, an essential component of the fungal cell wall. They are particularly effective against Candida and Aspergillus species.

5 Must Know Facts For Your Next Test

1. Echinocandins target the enzyme glucan synthase, disrupting fungal cell wall integrity.
2. They are often used to treat invasive candidiasis and aspergillosis.
3. Echinocandins are typically administered intravenously due to poor oral bioavailability.
4. Common examples include caspofungin, micafungin, and anidulafungin.
5. They have a favorable safety profile with fewer side effects compared to other antifungal agents.
