Ecallantide (Kalbitor) vs Rezafungin (Rezzayo)
An educational, source-based comparison of Ecallantide (Kalbitor) and Rezafungin (Rezzayo) — how each peptide works, what it's researched for, and what to know before going deeper.
Plasma kallikrein inhibitor for hereditary angioedema.
60-amino-acid recombinant protein that selectively inhibits plasma kallikrein, reducing bradykinin generation during HAE attacks.
- Hereditary angioedema (acute attacks, ≥12 yrs)
- • FDA-approved.
- • Boxed warning: anaphylaxis — administer by healthcare professional.
Once-weekly echinocandin for candidemia and invasive candidiasis.
Next-generation echinocandin structurally related to anidulafungin with enhanced stability, inhibiting β-(1,3)-D-glucan synthase; long half-life permits once-weekly IV dosing.
- Candidemia
- Invasive candidiasis
- • FDA-approved (2023).
- • Infusion reactions and photosensitivity reported.
