Hyperkalemia Risk Factors in Person Treated with Inhibitor of Renin-Angiotensin-Aldosterone System

Purpose: To identify risk factors for hyperkalemia in a patient being treated with an inhibitor of the renin-angiotensin-aldosterone system.

Description

Tang et al listed risk factors associated with hyperkalemia in a patient treated with a drug that inhibits the renin-angiotensin-aldosterone system such as an aldosterone receptor antagonist. A patient with one or more of these risk factors should be monitored for hyperkalemia during therapy with one of these agents.


 

Comorbid conditions:

(1) advanced age

(2) diabetes mellitus

(3) chronic renal insufficiency, especially when the GFR is < 30 mL per minute

 

Concurrent medications:

(1) beta-adrenergic blocker

(2) trimethoprim

(3) NSAID therapy

(4) COX-2 inhibitor

(5) potassium sparing diuretic (triamterene, amiloride)

 

Fluid and electrolytes:

(1) volume depletion from dehydration, diarrhea or overdiuresis
