The FDA has approved Airsupra (AstraZeneca), a metered-dose inhaler containing the short-acting beta₂-agonist (SABA) albuterol and the inhaled corticosteroid (ICS) budesonide, for use as needed for treatment or prevention of bronchoconstriction and to reduce the risk of exacerbations in patients ≥18 years old with asthma. Airsupra is the first combination of a SABA and an ICS to become available in the US. It is not approved for use as maintenance therapy.

The goal of asthma treatment is to control symptoms, prevent exacerbations, and maintain normal lung function. Management of acute exacerbations of asthma in the emergency department is not discussed here.

New drug formulations continue to be introduced for the treatment of asthma, and new studies on older drugs continue to change our perspectives on the management of this chronic inflammatory disease. Treatment of asthma in the emergency department or hospital is not addressed here. More information on the diagnosis and treatment of asthma is available from Expert Panel Report 2: Guidelines for the Diagnosis and Management of Asthma (Bethesda:NIH, 1997 and 2002 update; www.nhlbi.nih.gov).

Asthma is a chronic inflammatory disorder, with inflammation caused by allergens or other stimuli leading to bronchial hyperresponsiveness and obstruction of airflow.

Salmeterol xinafoate (Serevent - Allen & Hanburys), a long-acting β 2 -selective adrenergic agonist for inhalation, has been approved by the US Food and Drug Administration for maintenance treatment of asthma, with or without concurrent use of inhaled corticosteroids. Salmeterol is not recommended for acute treatment of bronchospasm.

Some commonly used systemic drugs that may cause pulmonary toxicity are listed in the table below. These adverse effects may sometimes be difficult to distinguish from the underlying disease (JAD Cooper, Jr et al, Am Rev Respir Dis, 133:321, 488, 1986). Pulmonary effects that are part of a generalized reaction or are indirect effects of drugs - on respiratory muscles, for example, or on the immune system - are not included here.
