Vasopressin (Vasostrict) vs Vosoritide (Voxzogo)
An educational, source-based comparison of Vasopressin (Vasostrict) and Vosoritide (Voxzogo) — how each peptide works, what it's researched for, and what to know before going deeper.
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.
C-type natriuretic peptide analog for achondroplasia.
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.
- Achondroplasia in children ≥5 years (now ≥4 months)
- • FDA-approved.
- • Transient blood pressure decrease; ensure adequate hydration/food before dosing.

Study-by-study comparison
| Peptide | Study | Source | Year | Summary |
|---|---|---|---|---|
| Vasopressin (Vasostrict) | VASST trial | NEJM | 2008 | Vasopressin added to norepinephrine did not reduce mortality overall but benefited less severe septic shock. |
| Vosoritide (Voxzogo) | Vosoritide Phase 3 trial | Lancet | 2020 | Increased annualized growth velocity vs placebo in children with achondroplasia. |
