Rezafungin (Rezzayo) vs Sincalide (Kinevac)
An educational, source-based comparison of Rezafungin (Rezzayo) and Sincalide (Kinevac) — how each peptide works, what it's researched for, and what to know before going deeper.
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.
Synthetic C-terminal octapeptide of cholecystokinin for gallbladder imaging.
Synthetic CCK-8 that binds CCK-A receptors on gallbladder smooth muscle, triggering contraction; used to assess gallbladder ejection fraction in cholescintigraphy.
- Gallbladder ejection fraction (HIDA scan)
- Pancreatic secretion testing
- Small bowel transit imaging
- • FDA-approved.
- • Abdominal cramping, nausea, diarrhea common; contraindicated in suspected gallstone obstruction.
