Cosyntropin (Cortrosyn) vs Sincalide (Kinevac)
An educational, source-based comparison of Cosyntropin (Cortrosyn) and Sincalide (Kinevac) — how each peptide works, what it's researched for, and what to know before going deeper.
Synthetic peptide containing the first 24 amino acids of ACTH — retains full corticotropic activity. Stimulates adrenal cortisol release for diagnostic testing.
- Primary and secondary adrenal insufficiency diagnosis
- • FDA-approved.
- • Single diagnostic dose; very well tolerated.
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.
