In treating hyperkalemia, what role does albuterol play?

Albuterol plays a role in treating hyperkalemia by promoting the movement of potassium from the extracellular space into the cells, which can help lower serum potassium levels temporarily. This effect occurs because albuterol, as a beta-2 adrenergic agonist, stimulates the beta-2 receptors on cell membranes, prompting cellular uptake of potassium.

While albuterol does assist in managing potassium levels, it does not directly promote excretion of potassium from the body, such as through renal mechanisms, nor does it decrease potassium absorption from the gastrointestinal tract. Its primary action relates to the redistribution of potassium within the body rather than its elimination or absorption processes. This makes it an effective adjunct treatment for hyperkalemia, particularly when rapid correction is needed.
