Cosyntropin (Cortrosyn) vs Vancomycin
An educational, source-based comparison of Cosyntropin (Cortrosyn) and Vancomycin — 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.
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').

Study-by-study comparison
| Peptide | Study | Source | Year | Summary |
|---|---|---|---|---|
| Cosyntropin (Cortrosyn) | Low-dose vs standard cosyntropin stimulation | JCEM | 2008 | Comparison of 1 mcg vs 250 mcg testing for secondary adrenal insufficiency. |
| Vancomycin | Vancomycin AUC vs trough monitoring | AJHP | 2020 | Updated consensus guidelines recommend AUC-guided dosing for MRSA. |

- Tag: FDA-Approved · Diagnostic vs FDA-Approved · Antibiotic.
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.
