Echinocandins

Also known as: Caspofungin (Cancidas), Micafungin (Mycamine), Anidulafungin (Eraxis), Rezafungin (Rezzayo)

Cyclic lipopeptide antifungals (caspofungin, micafungin, anidulafungin, rezafungin) for invasive Candida infections. FDA-approved. Prescription only.

Last updated

Mechanism of Action

Echinocandins are semisynthetic cyclic lipopeptides that noncompetitively inhibit beta-(1,3)-D-glucan synthase. This enzyme makes a glucan polymer essential to the fungal cell wall and has no human equivalent, which accounts for their good tolerability. They kill most Candida species and inhibit Aspergillus growth. Resistance is linked to mutations in the FKS genes that encode the enzyme.

Half-life
Caspofungin ~9–11 h; micafungin ~15 h; anidulafungin ~1 day; rezafungin ~5–6 days
Administration Routes
Intravenous
Research Status
Clinical

Reported Benefits

  • First-line treatment for candidemia and invasive candidiasis in most adults
  • Treat esophageal candidiasis (caspofungin, micafungin, anidulafungin)
  • Caspofungin is used for invasive aspergillosis in patients who can't tolerate other therapy and for suspected fungal infection in febrile neutropenia
  • Rezafungin's long half-life allows once-weekly dosing

Potential Side Effects

  • Liver enzyme elevations
  • Infusion-related reactions (flushing, rash, itching)
  • Fever, nausea and phlebitis
  • Photosensitivity and tremor reported with rezafungin

Common Dosing

Echinocandins are given intravenously by clinicians, usually in hospital. Caspofungin, micafungin and anidulafungin are given once daily (often with a loading dose), and rezafungin once weekly. Doses vary by drug and indication; caspofungin is adjusted for liver impairment. The prescribing clinician sets and supervises dosing.

Contraindications

  • Known hypersensitivity to any echinocandin
  • Caution in significant liver impairment
  • Poor penetration into the eye, central nervous system and urine limits use for those sites

Yes. Caspofungin (Cancidas) was approved in 2001, micafungin (Mycamine) in 2005, anidulafungin (Eraxis) in 2006, and rezafungin (Rezzayo) in March 2023 for candidemia and invasive candidiasis.

They target beta-glucan synthase, an enzyme fungi need for their cell wall that human cells don't have. Side effects are usually mild, such as liver enzyme changes and infusion reactions.

Resistance is still uncommon in most Candida species but has risen in Candida glabrata and is a concern in Candida auris. Susceptibility testing and stewardship help guide their use.
