Nonracemic Form of the Beta2-Agonist Albuterol

This nonracemic form of albuterol offers a significant reduction in the adverse effects associated with racemic albuterol (eg, muscle tremors, tachycardia, hyperglycemia, hypokalemia).

Levalbuterol (Xopenex, Xopenex HFA)

Nonracemic form of albuterol, levalbuterol (R isomer) is effective in smaller doses and is reported to have fewer adverse effects (eg, tachycardia, hyperglycemia, hypokalemia). The dose may be doubled in acute severe episodes when even a slight increase in the bronchodilator response may make a big difference in the management strategy (eg, in avoiding patient ventilation). It is available as an MDI (45 mcg per actuation) or solution for nebulized inhalation.
