Arformoterol tartrate	Brovana	Long-Acting beta-2 adrenergic agonist (LABA); Bronchodilator	Chronic Obstructive Pulmonary Disease	Selective long-acting beta-2 adrenergic receptor agonist, which produces relaxation of bronchial smooth muscle fibers leading to bronchodilation. It is the (R,R)-entantiomer of formoterol, and has a two-fold greater potency of racemic formoterol.
Bitolterol mesylate*	* Tornalate (No longer available in the United States)	Long-Acting beta-2 adrenergic agonist (LABA); Bronchodilator	Asthma; COPD (off-label)
Formoterol fumarate	Foradil Aerolizer; Perforomist	Long-Acting beta-2 adrenergic agonist (LABA); Bronchodilator	Asthma; Exercise induced asthma prophylaxis; COPD	Selective long-acting beta-2 adrenergic agonist which causes an increase in cyclic-AMP by stimulating intracellular adenyl cyclase. This action results in smooth muscle relaxation and inhibition of inflamatory mediators.
Salmeterol xinafoate	Serevent Diskus; Serevent HFA	Long-Acting beta-2 adrenergic agonist (LABA); Bronchodilator	Asthma; Exercise induced asthma prophylaxis; COPD	Selectively stimulates the beta-2 adrenergic receptors of intracellular adenyl cyclase, the catalyst for the conversion of adenosine triphosphate (ATP) to cyclic-1’,5’-adenosine monophosphate (cyclic AMP). This action causes an increase in cyclic AMP levels resulting in bronchial smooth muscle relaxation, and inhibition of the release of immediate hypersensitivity mediators from the mast cells.
