Cetrorelix (Cetrotide) vs Corticorelin (Acthrel)
An educational, source-based comparison of Cetrorelix (Cetrotide) and Corticorelin (Acthrel) — 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.
Synthetic ovine CRH for differential diagnosis of Cushing's syndrome.
Synthetic ovine corticotropin-releasing hormone (oCRH) that stimulates pituitary ACTH release; used in inferior petrosal sinus sampling and peripheral CRH stimulation testing to distinguish pituitary from ectopic ACTH-dependent Cushing's syndrome.
- Differential diagnosis of ACTH-dependent Cushing's syndrome
- • FDA-approved.
- • Transient flushing, dyspnea, hypotension possible.
