Desmopressin (DDAVP) vs Ecallantide (Kalbitor)
An educational, source-based comparison of Desmopressin (DDAVP) and Ecallantide (Kalbitor) — how each peptide works, what it's researched for, and what to know before going deeper.
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.
Plasma kallikrein inhibitor for hereditary angioedema.
60-amino-acid recombinant protein that selectively inhibits plasma kallikrein, reducing bradykinin generation during HAE attacks.
- Hereditary angioedema (acute attacks, ≥12 yrs)
- • FDA-approved.
- • Boxed warning: anaphylaxis — administer by healthcare professional.
