Effect of Nebulized Albuterol on Serum Lactate and Potassium in Healthy Subjects.

Objectives: The objectives were to determine if nebulized albuterol causes an increase in the serum lactate level compared to placebo and, secondarily, to confirm that albuterol decreases serum potassium levels compared to placebo in patients with normokalemia.

Methods: This was a randomized, double-blind, placebo-controlled trial. Twenty-eight healthy adult volunteers were assigned to receive either 10 mg of nebulized albuterol or placebo (nebulized saline) over 1 hour.
