An educational, source-based comparison of Cetrorelix (Cetrotide) and Etelcalcetide (Parsabiv) — how each peptide works, what it's researched for, and what to know before going deeper.
GnRH antagonist used in IVF to prevent premature ovulation.
Synthetic decapeptide that competitively blocks pituitary GnRH receptors, preventing LH surge during controlled ovarian stimulation.
- IVF / controlled ovarian stimulation
- • FDA-approved.
- • Used under specialist supervision.
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.
