What is Salmeterol and formoterol?

Β2-adrenergic selective, long-acting bronchodilators (LABA= Long-acting beta agonists). A single dose by a metered-dose inhalation device, provides sustained bronchodilation over 12 hours, compared with less than 3 hours for Albuterol. These agents are not recommended as monotherapy and are highly efficacious when combined with a corticosteroid. Salmeterol and formoterol are the agents of choice for treating nocturnal asthma in symptomatic patients taking other asthma medication
