Pegvisomant (Somavert) vs Vasopressin (Vasostrict)
An educational, source-based comparison of Pegvisomant (Somavert) and Vasopressin (Vasostrict) — how each peptide works, what it's researched for, and what to know before going deeper.
Pegylated GH receptor antagonist for acromegaly.
Genetically engineered analog of human GH with site-directed mutations blocking functional dimerization of the GH receptor; pegylation extends half-life. Lowers IGF-1 without lowering GH.
- Acromegaly inadequately controlled by surgery, radiation, or somatostatin analogs
- • FDA-approved.
- • Monitor LFTs; tumor monitoring via MRI required.
- • Lipohypertrophy at injection sites.
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.
