Desmopressin (DDAVP) vs Vasopressin (Vasostrict)
An educational, source-based comparison of Desmopressin (DDAVP) and Vasopressin (Vasostrict) — 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.
Endogenous nonapeptide that activates V1 vascular receptors to cause vasoconstriction and V2 renal receptors for water reabsorption. Used to raise blood pressure in catecholamine-resistant shock.
- Septic shock
- Cardiac arrest (historical)
- Diabetes insipidus
- • FDA-approved.
- • Ischemic complications possible at high doses.

Study-by-study comparison
| Peptide | Study | Source | Year | Summary |
|---|---|---|---|---|
| Desmopressin (DDAVP) | Desmopressin for nocturnal enuresis | Journal of Urology | 2006 | Effective short-term reduction of bedwetting in children. |
| Vasopressin (Vasostrict) | VASST trial | NEJM | 2008 | Vasopressin added to norepinephrine did not reduce mortality overall but benefited less severe septic shock. |
