Vancomycin vs Vasopressin (Vasostrict)
An educational, source-based comparison of Vancomycin and Vasopressin (Vasostrict) — how each peptide works, what it's researched for, and what to know before going deeper.
Glycopeptide antibiotic for serious Gram-positive infections including MRSA.
Tricyclic glycopeptide that binds the D-Ala-D-Ala terminus of peptidoglycan precursors, blocking cell wall cross-linking in Gram-positive bacteria.
- MRSA infections
- C. difficile colitis (oral)
- Enterococcal infections
- • FDA-approved.
- • Nephrotoxicity, infusion reactions ('red man syndrome').
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 |
|---|---|---|---|---|
| Vancomycin | Vancomycin AUC vs trough monitoring | AJHP | 2020 | Updated consensus guidelines recommend AUC-guided dosing for MRSA. |
| Vasopressin (Vasostrict) | VASST trial | NEJM | 2008 | Vasopressin added to norepinephrine did not reduce mortality overall but benefited less severe septic shock. |

Vancomycin — Frequently Asked Questions
Dalbavancin vs vancomycin — when is the long-acting agent preferred?+
Dalbavancin is typically considered for ABSSSI when a patient would otherwise need prolonged IV access, when adherence to a 10–14 day oral step-down is uncertain, or when avoiding hospitalization is a goal — for example in patients with unstable housing or IV drug use. Vancomycin remains a first-line inpatient agent with decades of comparative data and lower acquisition cost, at the trade-off of daily monitoring and IV line management.
