Beta-blockers block the action of catecholamines on β-adrenergic receptors. Asthma is a disease which is characterized by recurrent episodes of bronchospasm with periods of essentially normal lung function. Inhaled or injected β -agonists cause bronchodilation (via β2-adrenergic receptors) and are used in the management of asthma. Therefore, use of (nonselective) β-blockers may exacerbate or trigger bronchospasm in athletes/patients with asthma or pulmonary disease associated with hyper-reactive airways.
