4.2 Drug Indication

For use in the treatment of the following fungal infections: Candidemia and other forms of Candida infections (intra-abdominal abscess, and peritonitis), Aspergillus infections, and esophageal candidiasis. Also considered an alternative treatment for oropharyngeal canaidiasis.


FDA Label


Treatment of invasive candidiasis in adults and paediatric patients aged 1 month to < 18 years.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Anidulafungin is a semi-synthetic lipopeptide synthesized from a fermentation product of Aspergillus nidulans. Anidulafungin is an echinocandin, a class of antifungal drugs that inhibits the synthesis of 1,3-β-D-glucan, an essential component of fungal cell walls. Anidulafungin is active in vitro against many Candida, as well as some Aspergillus. Like other echinocandins, anidulafungin is not active against Cryptococcus neoformans, Trichosporon, Fusarium, or zygomycetes.


5.2 MeSH Pharmacological Classification

Antifungal Agents

Substances that destroy fungi by suppressing their ability to grow or reproduce. They differ from FUNGICIDES, INDUSTRIAL because they defend against fungi present in human or animal tissues. (See all compounds classified as Antifungal Agents.)

5.5 Absorption, Distribution and Excretion

Route of Elimination

Less than 1% of the administered radioactive dose was excreted in the urine. Anidulafungin is not hepatically metabolized.


Volume of Distribution

30 to 50 L


Clearance

1 L/h


5.6 Metabolism/Metabolites

Hepatic metabolism of anidulafungin has not been observed. Anidulafungin is not a clinically relevant substrate, inducer, or inhibitor of cytochrome P450 (CYP450) isoenzymes. Anidulafungin undergoes slow chemical degradation at physiologic temperature and pH to a ring-opened peptide that lacks antifungal activity.


5.7 Biological Half-Life

40-50 hours


5.8 Mechanism of Action

Anidulafungin is a semi-synthetic echinocandin with antifungal activity. Anidulafungin inhibits glucan synthase, an enzyme present in fungal, but not mammalian cells. This results in inhibition of the formation of 1,3-β-D-glucan, an essential component of the fungal cell wall, ultimately leading to osmotic instability and cell death.
