Corticorelin (Acthrel) vs Sincalide (Kinevac)
An educational, source-based comparison of Corticorelin (Acthrel) and Sincalide (Kinevac) — how each peptide works, what it's researched for, and what to know before going deeper.
Synthetic ovine CRH for differential diagnosis of Cushing's syndrome.
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.
- Differential diagnosis of ACTH-dependent Cushing's syndrome
- • FDA-approved.
- • Transient flushing, dyspnea, hypotension possible.
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.
