Oral ghrelin agonist for diagnosing adult growth hormone deficiency.
Oral ghrelin receptor (GHSR-1a) agonist that stimulates pituitary GH release; peak GH response is measured to evaluate adult GH deficiency.
- Diagnostic test for adult GH deficiency
- • FDA-approved.
- • Avoid with QT-prolonging drugs.
- • Hold strong CYP3A4 inducers prior to test.
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.
