- Angiotensin 2
Excipient information presented when available (limited, particularly for generics); consult specific product labeling.
Solution, Intravenous [preservative free]:
Giapreza: 2.5 mg/mL (1 mL)
Brand Names: U.S.
- Vasoactive Agent
Naturally occurring peptide hormone of the renin-angiotensin-aldosterone system (RAAS) that causes vasoconstriction and increases aldosterone release, which raises blood pressure.
Metabolized by aminopeptidase A and angiotensin converting enzyme 2 to angiotensin-(2-8) [angiotensin III] and angiotensin-(1-7), respectively in plasma, erythrocytes and many major organs.
Time to Peak
IV: <1 minute
Use: Labeled Indications
Septic or other distributive shock: To increase blood pressure in adults with septic or other distributive shock
There are no contraindications listed in the manufacturer's labeling.
Septic or other distributive shock (off-label dosing): Continuous IV infusion: Initial: 10 to 20 ng/kg/minute (Khanna 2017; manufacturer’s labeling); monitor response and titrate as frequently as every 5 minutes by increments of up to 15 ng/kg/minute as needed. Once the underlying shock has sufficiently improved, down-titrate every 5 to 15 minutes by increments of up to 15 ng/kg/minute based on response. Doses as low as 1.25 ng/kg/minute may be used.
Maximum initial dose: 80 ng/kg/minute during the first 3 hours of treatment.
Maximum maintenance dose: 40 ng/kg/minute.
Refer to adult dosing.
Dilute vial in NS to a final concentration of 5,000 ng/mL or 10,000 ng/mL:
Not fluid restricted: Dilute 2.5 mg/mL vial in 500 mL NS to a final concentration of 5,000 ng/mL.
Fluid restricted: Dilute 2.5 mg/mL vial in 250 mL NS to a final concentration of 10,000 ng/mL.
IV: Administer by continuous IV infusion via central venous line.
Store intact vials at 2°C to 8°C (36°F to 46°F). May store diluted solution at room temperature or under refrigeration ≤24 hours; discard diluted solution after 24 hours.
Angiotensin II Receptor Blockers: May diminish the therapeutic effect of Angiotensin II. Monitor therapy
Angiotensin-Converting Enzyme Inhibitors: May enhance the therapeutic effect of Angiotensin II. Monitor therapy
The following adverse drug reactions and incidences are derived from product labeling unless otherwise specified. Percentages are the result of combination vasopressor therapy.
Cardiovascular: Thrombosis (13%)
1% to 10%:
Cardiovascular: Tachycardia (9%), deep vein thrombosis (4%), peripheral ischemia (4%)
Central nervous system: Delirium (6%)
Endocrine & metabolic: Acidosis (6%), hyperglycemia (4%)
Hematologic & oncologic: Thrombocytopenia (10%)
Infection: Fungal Infection (6%)
Concerns related to adverse effects:
• Thrombosis: Arterial and venous thrombotic and thromboembolic events have been reported; use concurrent venous thromboembolism (VTE) prophylaxis.
Blood pressure response.
Animal reproduction studies have not been conducted. When treatment for septic or other disruptive shock is needed, delaying treatment due to pregnancy increases the risk of maternal and fetal morbidity and mortality.
What is this drug used for?
• It is used to treat low blood pressure.
