Ecallantide (Kalbitor) vs Vasopressin (Vasostrict)
An educational, source-based comparison of Ecallantide (Kalbitor) and Vasopressin (Vasostrict) — how each peptide works, what it's researched for, and what to know before going deeper.
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.
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.
