Administration
Use concurrent venous thromboembolism (VTE) prophylaxis during angiotensin II therapy.
Visually inspect parenteral products for particulate matter and discoloration prior to administration whenever solution and container permit. Angiotensin II is a clear, aqueous solution.
Dilution
Dilute in 0.9% Sodium Chloride Injection prior to use.
Withdraw 1 mL (2.5 mg) and add to 500 mL of 0.9% Sodium Chloride Injection for a final concentration of 5,000 ng/mL.
For the fluid restricted patient, withdraw 1 mL (2.5 mg) and add to 250 mL of 0.9% Sodium Chloride Injection or withdraw 2 mL (5 mg) and add to 500 mL of 0.9% Sodium Chloride Injection for a final concentration of 10,000 ng/mL.
Storage: Diluted solution may be stored at room temperature or under refrigeration for 24 hours.
Continuous IV Infusion
Administer through a central vein whenever possible; prolonged administration through a peripheral vein may result in extravasation and skin necrosis. If peripheral administration is necessary, use a 20-gauge or larger catheter and assess the site frequently. If extravasation occurs, administer 5 to 10 mg of phentolamine directly to the site.

Description
Renin-angiotensin-aldosterone system (RAAS) peptide hormone vasoconstrictor
Used for hypotension in adults with septic or other distributive shock
Associated with higher incidence of thrombosis and thromboembolic events; concurrent VTE prophylaxis necessary
Dosage And Indications
20 ng/kg/minute continuous IV infusion. Titrate by up to 15 ng/kg/minute every 5 minutes as needed to achieve or maintain target blood pressure. Do not exceed 80 ng/kg/minute during the first 3 hours then 40 ng/kg/minute thereafter. Doses as low as 1.25 ng/kg/minute may be used. Once underlying shock has improved, down titrate by up to 15 ng/kg/minute every 5 to 15 minutes based on blood pressure. Guidelines do not recommend angiotensin II as a first line vasopressor in septic shock but acknowledge it may have a role as an adjunctive vasopressor therapy.
Dosing Considerations
Specific guidelines for dosage adjustments in hepatic impairment are not available; it appears that no dosage adjustments are needed.
Specific guidelines for dosage adjustments in renal impairment are not available; it appears that no dosage adjustments are needed.

Mechanism Of Action
Angiotensin II is a peptide hormone of the renin-angiotensin-aldosterone system (RAAS) that causes vasoconstriction and an increase blood pressure. Angiotensin II raises blood pressure by vasoconstriction and increased aldosterone release. The direct action of angiotensin II on the vessel wall is mediated by binding to G-protein-coupled angiotensin II receptor type 1 on vascular smooth muscle cells, which stimulates calcium and calmodulin-dependent phosphorylation of myosin and causes smooth muscle contraction.
Pharmacokinetics
Angiotensin II is administered intravenously. It is metabolized by aminopeptidase A and angiotensin converting enzyme 2 to angiotensin III and angiotensin-(1-7), respectively, in plasma, erythrocytes, and many of the major organs. Angiotensin II type 1 receptor (AT1) mediated activity of angiotensin III is approximately 40% of angiotensin II. Aldosterone synthesis activity of angiotensin III is similar to that of angiotensin II. Angiotensin-(1-7) exerts opposite effects of angiotensin II on AT1 receptors and causes vasodilation.
Affected cytochrome P450 isoenzymes and/or drug transporters: none
Serum concentrations of angiotensin II are similar at baseline and hour 3 after infusion. After 3 hours, the serum concentration of angiotensin I, which is the angiotensin II precursor peptide, is reduced by approximately 40%. The plasma half-life of angiotensin II administered intravenously is less than 1 minute. Among the 70% of angiotensin II-treated patients who reached the target mean arterial pressure (MAP) at hour 3 in the ATHOS-3 trial, the median time to reach target MAP was approximately 5 minutes.
Pregnancy And Lactation
The published data on angiotensin II use in human pregnancy are not sufficient to determine a drug-associated risk of adverse developmental outcomes. Animal reproduction studies have not been conducted. Septic or other distributive shock is a medical emergency. Delayed treatment in pregnant women with hypotension associated with shock is likely to increase the risk of maternal and fetal morbidity and mortality.
It is unknown if angiotensin II is present in human milk. There are no data available on the effects of angiotensin II on the breast-feeding child or on milk production.
