Etelcalcetide (Parsabiv) vs Teduglutide (Gattex)

An educational, source-based comparison of Etelcalcetide (Parsabiv) and Teduglutide (Gattex) — how each peptide works, what it's researched for, and what to know before going deeper.

Calcium-Sensing Receptor Agonist · Endocrine
Etelcalcetide (Parsabiv)

Calcimimetic peptide for secondary hyperparathyroidism on hemodialysis.

Mechanism

Synthetic D-amino-acid peptide that binds the calcium-sensing receptor on parathyroid chief cells, increasing its sensitivity to extracellular calcium and lowering PTH secretion.

Research areas
  • Secondary hyperparathyroidism in adults on chronic hemodialysis
Considerations
  • FDA-approved.
  • Hypocalcemia common; monitor calcium and avoid in low corrected calcium.

GLP-2 Analog · Gastrointestinal
Teduglutide (Gattex)

GLP-2 analog for short bowel syndrome dependent on parenteral support.

Mechanism

Recombinant analog of glucagon-like peptide-2 with alanine→glycine substitution at position 2, resisting DPP-IV degradation; promotes intestinal mucosal growth, villus height, and absorptive capacity.

Research areas
  • Short bowel syndrome with intestinal failure
  • Reduction of parenteral nutrition dependence
Considerations
  • FDA-approved.
  • Colorectal polyp surveillance required.
  • Risk of intestinal obstruction and biliary/pancreatic disease.
