Anidulafungin (Eraxis) vs Ecallantide (Kalbitor)

An educational, source-based comparison of Anidulafungin (Eraxis) and Ecallantide (Kalbitor) — how each peptide works, what it's researched for, and what to know before going deeper.

Echinocandin · Antifungal
Anidulafungin (Eraxis)

Echinocandin lipopeptide for invasive Candida infections.

Mechanism

Semisynthetic lipopeptide that non-competitively inhibits β-(1,3)-D-glucan synthase, disrupting fungal cell wall synthesis in Candida and Aspergillus species.

Research areas
  • Candidemia and other invasive candidiasis
  • Esophageal candidiasis
Considerations
  • FDA-approved.
  • No dose adjustment for renal/hepatic impairment.
  • Infusion-related reactions possible.

Kallikrein Inhibitor · Immunology
Ecallantide (Kalbitor)

Plasma kallikrein inhibitor for hereditary angioedema.

Mechanism

60-amino-acid recombinant protein that selectively inhibits plasma kallikrein, reducing bradykinin generation during HAE attacks.

Research areas
  • Hereditary angioedema (acute attacks, ≥12 yrs)
Considerations
  • FDA-approved.
  • Boxed warning: anaphylaxis — administer by healthcare professional.
