Utility of inhaled β2-agonists in reducing serum potassium levels in adult patients with hyperkalemia: A scoping review

Inhaled β2-agonists, particularly nebulized salbutamol, represent an effective and safe therapeutic option for the acute reduction of serum potassium in adults with hyperkalemia. Their rapid onset of action and applicability across various patient profiles make them a valuable tool in emergency settings, especially where immediate access to advanced therapies such as dialysis is limited. Further research is warranted to evaluate long-term outcomes, safety in patients with cardiovascular comorbidities, and optimal dosing strategies.
