Hyperkalaemia continues to be a major hazard of mineralocorticoid receptor blockade in an effort to retard the progression of chronic kidney disease (CKD). In cardiac patients on mineralocorticoid receptor blockade, RLY-5016 which captures K(+) in the colon has been effective in reducing the risk of hyperkalaemia. This compound might be useful in CKD as well.
Keywords: aldosterone blockade; chronic kidney disease; hyperkalaemia; potassium binder.
