- Background
Angiotensin II is under investigation for the treatment of Sepsis, Septic Shock, Diabetes Mellitus, and Acute Renal Failure. Angiotensin II has been investigated for the treatment, basic science, and diagnostic of Hypertension, Renin Angiotensin System, and Idiopathic Membranous Nephropathy.
As of December 21, 2017 the FDA approved La Jolla Pharmaceutical's Giapreza (angiotensin II) Injection for Intravenouse Infusion for the indication of acting as a vasoconstrictor to increase blood pressure in adults with septic or other distributive shock. The novelty of the medication lies in the fact that it is the first and only use of synthetic human angiotensin II to help maintain body blood pressure.
Shock is the inability to maintain blood flow to vital tissues and the potential resultant organ failure and death within hours, no matter young or o ld. As distributive shock is the most common type of shock in the inpatient setting and affects up to one third of patients in the intensive care unit, the FDA determined that there is a need for treatment options for critically ill hypotensive patients who do not adequately respond to currently available therapies.

Angiotensin II is a naturally occurring peptide hormone of the renin-angiotensin-aldosterone-system (RAAS) that has the capacity to cause vasoconstriction and an increase in blood pressure in the human body. Label
In the RAAS, juxtaglomerular cells of the renal afferent arteriole synthesize the proteolytic enzyme renin. Although stored in an inactive form called pro-renin, decreases in arterial blood pressure or extracellular fluid volume depletion can cause various enzymatic reactions to release active renin into the systemic circulation and surrounding tissues. Such renin release allows for the production of the alpha-2-globulin angiotensinogen predominantly in the liver and to some extent, the kidneys and other organs. 1
Angiotensin I, itself a decapeptide with weak biological activity, is produced from angiotensinogen and then quickly converted to angiotensin II by angiotensin converting enzymes (ACE). Consequently, angiotensin II demonstrates its strong vasopressor activity when it is rapidly degraded by aminopeptidases A and M into further entities like angiotensin III and angiotensin IV, respectively. Such species like angiotensin III can then bind and interact with specific G protein coupled receptors like angiotensin receptor 1, or AT-1 1 where strong vasoconstricson can occur. 1
Furthermore, in the ATHOS-3 clinical trial, for the 114 (70%) patient subjects in the angiotensin II arm who reached the target mean arterial pressure (MAP) at Hour 3, the median time to reach the target MAP endpoint was approximately 5 minutes. The angiotensin II was titrated to effect for each individual patient. Label.
- Mechanism of action
As part of the renin-angiotensin-aldosterone-system (RAAS), angiotensin II raises blood pressure by vasoconstriction, increased aldosterone release by the adrenal zona glomerulosa, sodium and water reabsorption in the proximal tubular cells, and vasopressin secretion Label,1
The direct action of angiotensin II on surrounding vessel walls is facilitated by binding to the G-protein-coupled angiotensin II receptor type 1 (AT-1) on vascular smooth muscle cells, which stimulates Ca2+/calmodulin-dependent phosphorylation of myosin and causes smooth muscle contraction that results in vasoconstriction Label,1.
The RAAS is ultimately regulated by a negative feedback effect of angiotensin II on renin production by the juxtaglomerular cells of the renal afferent arteriole. Unresuscitated septic shock associated with marked hypovolemia, extracellular fluid volume depletion, decreased cardiac output, low arterial blood pressure and decreased systemic vascular resistance causes an increase in renin secretion by the juxtaglomerular cells, resulting in elevated angiotensin II plasma levels and an increased secretion of aldosterone from the adrenal cortex. Angiotensin II binding to AT-1 receptors causes dose-dependent vasoconstriction of both afferent and efferent glomerular arterioles. The most pronounced effect of angiotensin II results on efferent arterioles, resulting in reduced renal blood flow and increased glomerular filtration pressure. 1
Target Actions Organism UType-1 angiotensin II receptor agonistHumans - Absorption
Following the intravenous infusion of angiotensin II in adult patients with septic or other distributive shock, the serum levels of angiotensin II observed were similar at baseline and hour 3 after the intravenous infusion. After 3 hours of treatment, the serum level of angiotensin I (the angiotensin II precursos peptide) is however, reduced by about 40% Label.
- Volume of distribution
The official prescribing information for angiotensin II notes that no specific studies have yet been conducted that examine the distribution of angiotensin II Label.
- Protein binding
Not Available
- Metabolism
It is 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 of the major organs (i.e. intestine, kidney, liver and lung). Angiotensin II type 1 receptor (AT1) mediated activity of angiotensin III is approximately 40% of angiotensin II; however, aldosterone synthesis activity is similar to angiotensin II. Angiotensin-(1-7) exerts the opposite effects of angiotensin II on AT1 receptors and causes vasodilation Label.
Nevertheless, the official prescribing information also notes that no formal studies have been conducted that examine the metabolism of angiotensin II Label.

Overdose with angiotensin II would be expected to result in hypertension, necessitating close monitoring and supportive care Label. Effects are also expected to be brief as the half-life of angiotensin II is less than one minute Label.
In the ATHOS-3 clinical study there was a higher incidence of arterial and venous thrombotic and thromboembolic events in patients who received angiotensin II compared to placebo treated patients. The major imbalance was in deep venous thromboses - which prompts the potential need to use concurrent venous thromboembolism (VTE) prohphylaxis Label.
Adverse effects of noticeable potential (>= 10%) include thromboembolic events (ie. like deep vein thrombosis) including arterial and venous thrombotic events, thrombocytopenia, tachycardia, and fungal infection. Effects whose potential are < 10% include delirium, acidosis, hyperglycemia, peripheral ischemia Label.
Concomitant use of angiotensin converting enzymes (ACE) inhibitors may increase the response of angiotensin II Label.
Concomitant use of angiotensin II blockers (ARBs) may decrease the response to angiotensin II Label.
There are no formal data regarding the safe use of angiotensin II in pregnant women. However, septic or other distributive shock is a medical emergency that can be fatal if left untreated. Delaying treatment in pregnant women with hypotension associated with septic or otherdistributive shock is likely to increase the risk of maternal and fetal morbidity and mortality Label.
There is no formal data regarding whether or not angiotensin II may become present in human milk and there is no data available on the effects of angiotensin II on the breastfed child or the effects on milk production Label.
The safety and efficacy of angiotensin II in pediatric patients has not yet been established Label.
There is no difference in the safety or efficacy between patients less than 65 years old and those 65 years or older when treated with angiotensin II Label.
There is no difference in pharmacokinetics between male and female patients Label.
The pharmacokinetics of angiotensin II are not expected to be influenced by renal impairment or hepatic impairment Label.
