Overcoming the Causes (and Consequences) of Chronic Hyperkalemia

To participate in this activity, please:

Chronic hyperkalemia has several possible causes, including impaired renal excretion of potassium due to a decrease in mineralocorticoid activity, often resulting from renin-angiotensin-aldosterone system inhibitor (RAASi) therapy. While limiting potassium intake and avoiding the use of RAASi therapy are common strategies to manage patients who develop chronic hyperkalemia, both have important negative consequences on patient outcomes, particularly related to the kidneys. Sodium polystyrene sulfonate has often been used to bind potassium, but limited effectiveness and gastrointestinal toxicity limit its use. In the past few years, 2 additional potassium-binding agents have become available with evidence of effectiveness and safety. In addition, a nonsteroidal mineralocorticoid receptor antagonist with reduced potential for hyperkalemia has recently become available. This case-based activity touches on the diagnostic and clinical challenges faced in the primary care management of patients with chronic hyperkalemia with suggestions for integrating the evolving options into practice to improve patient outcomes.
