Cosyntropin (Cortrosyn) vs Desmopressin (DDAVP)
An educational, source-based comparison of Cosyntropin (Cortrosyn) and Desmopressin (DDAVP) — how each peptide works, what it's researched for, and what to know before going deeper.
Synthetic peptide containing the first 24 amino acids of ACTH — retains full corticotropic activity. Stimulates adrenal cortisol release for diagnostic testing.
- Primary and secondary adrenal insufficiency diagnosis
- • FDA-approved.
- • Single diagnostic dose; very well tolerated.
Synthetic vasopressin analog for diabetes insipidus and nocturnal enuresis.
Synthetic analog of arginine vasopressin with enhanced antidiuretic activity and negligible vasopressor effect. Acts on renal V2 receptors to increase water reabsorption; also increases factor VIII and vWF release.
- Central diabetes insipidus
- Primary nocturnal enuresis
- Hemophilia A
- von Willebrand disease type 1
- • FDA-approved.
- • Risk of hyponatremia — limit fluids around dosing.
