Sincalide (Kinevac) vs Vosoritide (Voxzogo)
An educational, source-based comparison of Sincalide (Kinevac) and Vosoritide (Voxzogo) — how each peptide works, what it's researched for, and what to know before going deeper.
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.
C-type natriuretic peptide analog for achondroplasia.
Modified C-type natriuretic peptide (CNP) analog that binds NPR-B, antagonizing overactive FGFR3 signaling in the growth plate to increase endochondral bone growth in children with achondroplasia.
- Achondroplasia in children ≥5 years (now ≥4 months)
- • FDA-approved.
- • Transient blood pressure decrease; ensure adequate hydration/food before dosing.
