Rezafungin (Rezzayo) vs Vasopressin (Vasostrict)

An educational, source-based comparison of Rezafungin (Rezzayo) and Vasopressin (Vasostrict) — how each peptide works, what it's researched for, and what to know before going deeper.

Echinocandin · Antifungal
Rezafungin (Rezzayo)

Once-weekly echinocandin for candidemia and invasive candidiasis.

Mechanism

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.

Research areas
  • Candidemia
  • Invasive candidiasis
Considerations
  • FDA-approved (2023).
  • Infusion reactions and photosensitivity reported.

Vasopressor · Hormonal
Vasopressin (Vasostrict)

Nonapeptide hormone used for vasodilatory shock.

Mechanism

Endogenous nonapeptide that activates V1 vascular receptors to cause vasoconstriction and V2 renal receptors for water reabsorption. Used to raise blood pressure in catecholamine-resistant shock.

Research areas
  • Septic shock
  • Cardiac arrest (historical)
  • Diabetes insipidus
Considerations
  • FDA-approved.
  • Ischemic complications possible at high doses.
