Adrenergic beta-agonists (beta-agonists) are "drugs that selectively bind to and activate beta-adrenergic receptors."[1]

Medical uses

Asthma

Chronic obstructive pulmonary disease

Among patients with COPD, reduction in mortality may not occur unless LABAs are combined with corticosteroids.[2]

Drug toxicity

Long acting adrenergic beta-agonists (LABA) associated with may adverse outcomes among patients with asthma when used without corticosteroids and maybe among African American patients.[3] They might be safe in asthma as long as corticosteroids are used. According to a meta-analyses by the Cochrane Collaboration, when used with corticosteroids the relative risk for asthma-related death is increased at 1.34 although this increase was not statistically significant with a confidence interval of 0.30 to 5.97.[4][5] There are two major randomized controlled trials of LABAs.[6][7]
