Vasopressin (Vasostrict)9 residuesCYFQNCPRGEach bubble = one amino acid. Size = residue mass. Color = chemical class.Vasopressin (AVP/ADH) is an FDA-approved nonapeptide vasopressor for septic and vasodilatory shock, backed by two landmark ICU trials totaling 1,187 patients. Hospital-administered by continuous IV infusion only. Not a self-use peptide. Community interest focuses on intranasal analogs for memory and cognition.

Vasopressin is not a self-administration peptide. Everything here applies to ICU clinicians managing the drug on a ventilated or monitored patient. Standard ICU concentration is 0.1 U/mL. Dilute 25 units into 250 mL of 0.9% normal saline or D5W. At that concentration, 0.01 U/min equals 6 mL/hr, 0.03 U/min equals 18 mL/hr, and 0.04 U/min equals 24 mL/hr on the infusion pump. Premixed bags are available at 0.2, 0.4, and 0.6 U/mL concentrations. Use them when possible. The 20 U/mL concentrate vials look similar to the diluted infusion bags, and medication errors from that confusion are documented. Smart pump drug libraries reduce rate-programming errors. Never bolus vasopressin; it causes severe acute hypertension and myocardial ischemia. Start the taper once MAP holds at 65 mmHg for 8 hours without catecholamines. Reduce by 0.005 U/min every 15 to 30 minutes and monitor sodium and urine output for 24 to 48 hours after the infusion stops completely.
