Corticorelin (Acthrel) vs Icatibant (Firazyr)
An educational, source-based comparison of Corticorelin (Acthrel) and Icatibant (Firazyr) — how each peptide works, what it's researched for, and what to know before going deeper.
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.
Bradykinin B2 receptor antagonist for hereditary angioedema attacks.
Synthetic decapeptide that competitively blocks the bradykinin B2 receptor, halting the vascular leak that drives HAE swelling attacks.
- Hereditary angioedema (acute attacks)
- • FDA-approved.
- • Injection-site reactions very common.
