Romiplostim (Nplate) vs Sincalide (Kinevac)
An educational, source-based comparison of Romiplostim (Nplate) and Sincalide (Kinevac) — how each peptide works, what it's researched for, and what to know before going deeper.
Thrombopoietin-receptor peptibody for immune thrombocytopenia.
Peptibody (Fc-peptide fusion) containing TPO receptor-binding peptide domains that activate c-Mpl on megakaryocytes, stimulating platelet production without competing with endogenous TPO.
- Chronic immune thrombocytopenia (ITP)
- Pediatric ITP
- Hematopoietic syndrome of acute radiation
- • FDA-approved.
- • Reticulin fiber deposition in bone marrow; thrombosis risk with over-correction.
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.
