From the Guidelines
The best treatment for hyperkalemia is a multifaceted approach that includes immediate stabilization with calcium gluconate, temporary reduction of potassium levels with insulin and glucose or nebulized albuterol, and definitive removal of potassium with agents like sodium polystyrene sulfonate, patiromer, or sodium zirconium cyclosilicate, as supported by the most recent and highest quality study 1.
Treatment Approach
The management of hyperkalemia depends on its severity and underlying cause. For mild cases, dietary restrictions and discontinuation of potassium-increasing medications may suffice. However, for moderate to severe hyperkalemia, more aggressive interventions are necessary.
- Stabilization: Calcium gluconate (10 mL of 10% solution IV over 2-3 minutes) is administered to stabilize cardiac membranes and prevent arrhythmias, although it does not lower potassium levels.
- Temporary Reduction: Insulin (10 units regular insulin IV) with glucose (25g IV) or nebulized albuterol (10-20 mg) can temporarily lower serum potassium levels by shifting potassium into cells.
- Definitive Removal: Sodium polystyrene sulfonate (15-30g orally or rectally), patiromer (8.4-25.2g daily), or sodium zirconium cyclosilicate (10g three times daily) can be used for definitive potassium removal.
- Severe Cases or Renal Failure: Hemodialysis provides rapid and effective potassium removal in severe cases or renal failure.
Ongoing Management
Ongoing monitoring of potassium levels, cardiac function, and addressing the underlying cause are crucial components of hyperkalemia management. The use of newer potassium-binding agents, such as patiromer and sodium zirconium cyclosilicate, may facilitate the optimization of renin-angiotensin-aldosterone system inhibitor (RAASi) therapy, as noted in recent clinical studies 1.
Key Considerations
- Monitoring: Serum potassium levels should be monitored closely, especially in patients with chronic kidney disease, diabetes, heart failure, or a history of hyperkalemia, and in those receiving RAASi therapy.
- Dietary Restrictions: A low-potassium diet may be recommended to reduce the occurrence of hyperkalemia.
- Medication Adjustment: The co-administration of drugs known to promote hyperkalemia or reduce kidney function should prompt more frequent monitoring of potassium levels.
By following this approach and considering the latest evidence, healthcare providers can effectively manage hyperkalemia, minimize its risks, and improve patient outcomes.
From the FDA Drug Label
Sodium polystyrene sulfonate is indicated for the treatment of hyperkalemia. The average total daily adult dose of Sodium Polystyrene Sulfonate is 15 g to 60 g, administered as a 15 g dose (four level teaspoons), one to four times daily.
The best treatment for hyperkalemia is Sodium Polystyrene Sulfonate, with a recommended dosage of 15 g to 60 g per day, administered orally or rectally, depending on the severity and resistance of hyperkalemia 2.
- The treatment should be administered with caution, considering the risk of intestinal necrosis and other gastrointestinal adverse events.
- It is essential to avoid concomitant administration of sorbitol and use only in patients with normal bowel function.
- The treatment should be discontinued in patients who develop constipation.
