Corticorelin (Acthrel) vs Rezafungin (Rezzayo)

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

CRH Analog · Diagnostics
Corticorelin (Acthrel)

Synthetic ovine CRH for differential diagnosis of Cushing's syndrome.

Mechanism

Synthetic ovine corticotropin-releasing hormone (oCRH) that stimulates pituitary ACTH release; used in inferior petrosal sinus sampling and peripheral CRH stimulation testing to distinguish pituitary from ectopic ACTH-dependent Cushing's syndrome.

Research areas
  • Differential diagnosis of ACTH-dependent Cushing's syndrome
Considerations
  • FDA-approved.
  • Transient flushing, dyspnea, hypotension possible.

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.
