Angiotensin Ii Mechanism, CYP450 Pathways & DailyMed Monograph

RxCUI 1999007 • NDC 68547-005

1. Indications and usage giapreza: increases blood pressure in adults with septic or other distributive shock . GIAPREZA is a vasoconstrictor to increase blood pressure in adults with septic or other distributive shock. ( 1 )

12.1. Mechanism of Action Angiotensin II raises blood pressure by vasoconstriction and increased aldosterone release. Direct action of angiotensin II on the vessel wall is mediated by binding to the G-protein-coupled angiotensin II receptor type 1 on vascular smooth muscle cells, which stimulates Ca 2+ /calmodulin-dependent phosphorylation of myosin and causes smooth muscle contraction.

With Terminal t½ estimated at 7–18 hrs depending on renal/hepatic reserve (Angiotensin Ii) residence kinetics and Complete (~100%) parenteral systemic delivery for Angiotensin Ii (2.5 mg/mL Injection) bioavailability, Angiotensin Ii undergoes mixed metabolic conjugation and unchanged urinary excretion across angiotensin ii regimens and establishes therapeutic activity over rapid intravascular/parenteral onset within 15–45 minutes after angiotensin ii administration.

Standard adult regimens span 2.5 mg/mL Injection, .5 mg/mL Injection. Prescribers screen specifically against contraindications none.; prior anaphylaxis, angioedema, or severe hypersensitivity to angiotensin ii or angiotensin ii excipients, while community micro-logs most frequently note nausea (8.5% of reports), headache (7.1% of reports), dizziness (6.2% of reports).

Key Monitored Interactions:
RAAS Modulators & Potassium-Sparing Diuretics Moderate

Combining Angiotensin Ii with ACE inhibitors, ARBs, or aldosterone blockers can shift serum potassium and eGFR.

Duplicate Vasoconstrictor Agents Moderate

Avoid overlapping vasoconstrictor prescriptions alongside Angiotensin Ii to prevent cumulative receptor toxicity.
