Potassium control in chronic kidney disease: implications for neuromuscular function

Abstract

In Australia, approximately 1.7 million adults have evidence of chronic kidney disease (CKD). This complex disease can result in a multitude of complications, including hyperkalaemia, which is common and well recognised. The advent of new therapeutics aimed at lowering serum potassium has raised the possibility of optimising potassium control to enable greater use of renin–angiotensin–aldosterone system inhibitors in the management of CKD. Recent studies suggest that hyperkalaemia also has implications for peripheral neuropathy in CKD, a complication that substantially contributes to patient morbidity. This review examines evidence of the relationship between potassium and peripheral neuropa..
