Mechanism of action
Angiotensin II receptor antagonists block angiotensin II AT1 receptors. Along with Angiotensin-converting enzyme inhibitors, they act on the renin-angiotensin system; the two classes may be used synergistically.
Applications
These drugs are primarily antihypertensives. They may also be used to protect the kidneys.
Adverse effects
Angiotensin II receptor antagonists can cause hyperkalemia. The rise in potassium has been reported to be both similar to[1] and less that occurs with angiotensin-converting enzyme inhibitors.[2]
