Treatment of infant formula with patiromer dose dependently decreases potassium concentration

Hyperkalemia is a potentially life-threatening complication of chronic kidney disease (CKD). Dietary potassium restriction is challenging in infants despite low-potassium formulas. Decreasing potassium in formula using patiromer, a new calcium-based cation exchange polymer may be one option to accomplish this; however, data confirming efficacy is lacking. Varying doses of patiromer were added to prepared Similac Advance and Similac PM 60/40....
