These agents relax airway smooth muscle, thus causing bronchodilation in patients with reversible airway obstruction, such as asthma.

Albuterol (Proventil HFA, Ventolin HFA, ProAir HFA)

Albuterol relaxes bronchial smooth muscle by action on beta2 receptors with little effect on cardiac muscle contractility. Administer continuous nebulization with a pump-driven aerosol or via a small-particle aerosol generator

Levalbuterol (Xopenex, Xopenex HFA)

Levalbuterol is a selective beta2-agonist. Albuterol is a racemic mixture, while levalbuterol contains only the levo isomer of albuterol. The safety and efficacy of levalbuterol have not been determined in children under 12 years; multicenter trials in children aged 12 years and younger are ongoing.


Terbutaline is a selective beta2-adrenergic agent. It produces relaxation of airway smooth muscle, resulting in bronchodilation in patients with asthma.
