Drug treatment of asthma

[Becky]

Major drug classes commonly used in the treatment of asthma and asthma exacerbations include

Bronchodilators (beta-2 agonists, anticholinergics)
Corticosteroids
Leukotriene modifiers
Mast cell stabilizers
Methylxanthines
Immunomodulators

Drugs in these classes (see table Drug Treatment of Chronic Asthma) are inhaled, taken orally, or injected subcutaneously or intravenously; inhaled drugs come in aerosolized and powdered forms. Use of aerosolized forms with a spacer or holding chamber facilitates deposition of the drug in the airways rather than the pharynx; patients are advised to wash and dry their spacers after each use to prevent bacterial contamination. In addition, use of aerosolized forms requires coordination between actuation of the inhaler (drug delivery) and inhalation; powdered forms reduce the need for coordination, because drug is delivered only when the patient fully inhales with a good effort.
