Etelcalcetide (Parsabiv) vs Vosoritide (Voxzogo)
An educational, source-based comparison of Etelcalcetide (Parsabiv) and Vosoritide (Voxzogo) — how each peptide works, what it's researched for, and what to know before going deeper.
Calcimimetic peptide for secondary hyperparathyroidism on hemodialysis.
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.
- Secondary hyperparathyroidism in adults on chronic hemodialysis
- • FDA-approved.
- • Hypocalcemia common; monitor calcium and avoid in low corrected calcium.
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.
