Corticorelin (Acthrel) vs Vosoritide (Voxzogo)

An educational, source-based comparison of Corticorelin (Acthrel) and Vosoritide (Voxzogo) — how each peptide works, what it's researched for, and what to know before going deeper.

CRH Analog · Diagnostics
Corticorelin (Acthrel)

Synthetic ovine CRH for differential diagnosis of Cushing's syndrome.

Mechanism

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.

Research areas
  • Differential diagnosis of ACTH-dependent Cushing's syndrome
Considerations
  • FDA-approved.
  • Transient flushing, dyspnea, hypotension possible.

CNP Analog · Skeletal Growth
Vosoritide (Voxzogo)

C-type natriuretic peptide analog for achondroplasia.

Mechanism

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.

Research areas
  • Achondroplasia in children ≥5 years (now ≥4 months)
Considerations
  • FDA-approved.
  • Transient blood pressure decrease; ensure adequate hydration/food before dosing.
