Overview

Anidulafungin is a semisynthetic, echinocandin antifungal agent.

Anidulafungin, a semisynthetic lipopeptide synthesized from a fermentation product of Aspergillus nidulans, is an echinocandin antifungal agent. Echinocandins (e.g., anidulafungin, caspofungin, micafungin) are glucan synthesis inhibitors and differ structurally and pharmacologically from other currently available antifungal agents.

Like other echinocandins, anidulafungin inhibits the synthesis of beta(1,3)-d-glucan, an integral component of the fungal cell wall that is not present in mammalian cells. The drug may be fungistatic and fungicidal in action.

Anidulafungin undergoes slow chemical degradation at physiologic temperature and pH to a ring-opened peptide that lacks antifungal activity. The drug does not appear to undergo hepatic metabolism. Anidulafungin is not a clinically important substrate for and does not inhibit or induce cytochrome P-450 (CYP) isoenzymes and does not appear to have clinically important effects on the metabolism of drugs metabolized by these hepatic isoenzymes.

The drug is more than 99% bound to plasma proteins. The elimination half-life of anidulafungin at steady state is approximately 27-52 hours. Steady-state concentrations are achieved within 24 hours of administration of the initial loading dose (twice the daily maintenance dosage); the estimated plasma accumulation factor during steady state is approximately 2.

Anidulafungin is eliminated principally in feces via the biliary tract, mostly as degradation products of the drug. In healthy individuals, about 30% of a single IV dose of radiolabeled anidulafungin was recovered in feces over 9 days (less than 10% was unchanged drug); less than 1% of the dose is eliminated in urine.

USES: This medication is used to treat a variety of fungal infections. Anidulafungin belongs to a class of drugs known as echinocandins. It works by stopping the growth of fungi.
