Because hyperkalemia is central to the etiology of this disorder, [17] a major treatment goal is to lower the serum K+ level. This can be achieved by placing the patient on a low-K+ diet (1 mEq/kg K+/d) and by withdrawal of drugs that can cause hyperkalemia (eg, angiotensin-converting enzyme [ACE] inhibitors, nonsteroidal anti-inflammatory drugs). Loop diuretics can be helpful in reducing serum potassium levels as long as the patient is not hypovolemic.
