Beta2-adrenergic agonists CATEGORY CLASS ______________________________________________________________________ PURPOSE OF MEDICATION

Expected Pharmacological Action Beta2-adrenergic agonists act by selectively activating the beta2-receptors in the bronchial smooth muscle, resulting in bronchodilation. As a result of this: - Bronchospasm is relieved. - Histamine release is inhibited. - Ciliary motility is increased.

Therapeutic Use - Prevention of asthma episode (exercise-induced) - Inhaled, short-acting, used for prevention of asthma - Treatment for bronchospasm - Long-term control of asthma

Complications Tachycardia, angina (Oral agents can cause tachycardia and angina due to activation of alpha1 receptors in the heart.) Tremors (Caused by activation of beta2 receptors in skeletal muscle)

Medication Administration Inhaled, short-acting Oral, long-acting

Contraindications/Precautions - Pregnancy Risk Category C - Contraindicated in clients who have tachydysrhythmia. - Use cautiously in clients who have diabetes mellitus, hyperthyroidism, heart disease, hypertension, and angina.

Nursing Interventions n/a

Interactions - Use of beta-adrenergic blockers can negate effects of both medications. - MAOIs and tricyclic antidepressants can increase the risk of tachycardia and angina.

Client Education Evaluation of Medication Effectiveness - Long-term control of asthma - Prevention of exercise-induced asthma - Resolution of asthma exacerbations as evidenced by absence of shortness of breath, clear breath sounds, absence of wheezing, and return of respiratory rate to baseline

ACTIVE LEARNING TEMPLATES

- When a client has prescriptions for an inhaled beta2-agonist and an inhaled glucocorticoid, advise the client to inhale the beta2-agonist before inhaling the glucocorticoid. The beta2-agonist promotes bronchodilation and enhances absorption of the glucocorticoid. - A short-acting beta2-agonist is used to treat an acute episode. - Formoterol and salmeterol are long-acting beta2-agonist inhalers. These inhalers are used every 12 hr for long-term control and are not used to abort an asthma attack, or exacerbation.
