Beta-agonists should be administered with caution to patients being treated with drugs known to prolong the QT interval because the action of beta-agonists on the cardiovascular system may be potentiated. 1.25 to 5 mg via oral inhalation every 4 to 8 hours as needed for bronchospasm is recommended by the National Asthma Education and Prevention Program (NAEPP) Expert panel. 6 to 12 years: 24 mg/day PO for syrup and tablets; FDA-approved labeling for inhaler recommends not exceeding 12 puffs/day; FDA-approved labeling for nebulizer solution for oral inhalation recommends not exceeding 4 doses/day or 10 mg/day (0.083% or 0.5% nebulizer solution), 2.5 mg/day (0.63 mg/3 mL nebulizer solution), and 5 mg/day (1.25 mg/3 mL nebulizer solution). For those who use a short-acting beta-agonist on a daily basis, a controller agent (e.g., inhaled corticosteroid, leukotriene receptor antagonist) should be considered if albuterol tolerance develops. Beta-agonists and beta-blockers are pharmacologic opposites, and will counteract each other to some extent when given concomitantly, especially when non-cardioselective beta blockers are used. For the acute treatment of severe episodes, the National Asthma Education and Prevention Program Expert Panel recommends 4 to 8 puffs every 20 minutes for up to 4 hours, then 4 to 8 puffs every 1 to 4 hours as needed. In some patients, 1 puff every 4 hours may be sufficient. Guaifenesin; Phenylephrine: (Moderate) Caution and close observation should be used when albuterol is used concurrently with other adrenergic sympathomimetics, administered by any route, to avoid potential for increased cardiovascular effects. This risk may be more clinically significant with long-acting beta-agonists as compared to short-acting beta-agonists. Beta-agonists may be associated with adverse cardiovascular effects including QT interval prolongation, usually at higher doses and/or when associated with hypokalemia. Monitoring of potassium levels would be advisable.

Drugs with a possible risk for QT prolongation and TdP that should be used cautiously with TCAs include the beta-agonists. For acute asthma exacerbations, NAEPP recommends 0.15 mg/kg/dose (Min: 2.5 mg/dose) every 20 minutes for 3 doses, then 0.15 to 0.3 mg/kg/dose (Max: 10 mg/dose) every 1 to 4 hours as needed or 0.5 mg/kg/hour by continuous nebulization. Albuterol is preferred over other SABAs due to extensive safety-related information during pregnancy. The R-isomer, known as levalbuterol, is primarily responsible for bronchodilation. Caffeine is a CNS-stimulant and beta-agonists are sympathomimetic agents. Bretylium: (Minor) The use of bretylium (a class III antiarrhythmic agent) in conjunction with other drugs associated with QT prolongation should be used with caution due to the potential risk for ventricular tachycardia, including torsade de pointes. The answer is yes. Inhaled short-acting beta-2 agonists (SABAs) are the therapy of choice for preventing exercise-induced bronchospasm, and they are strongly recommended by the American Thoracic Society for EIB prophylaxis. This risk may be more clinically significant with long-acting beta-agonists as compared to short-acting beta-agonists. Drugs with a possible risk for QT prolongation and TdP that should be used cautiously and with close monitoring with erythromycin include the beta-agonists. Caution may be warranted during the administration of high doses in patients with renal impairment, as renal clearance is reduced. Obtain an electrocardiogram at baseline and periodically during treatment. In some patients, 90 mcg (1 oral inhalation) every 4 hours may be sufficient. Beta-agonists can sometimes increase heart rate or have other cardiovascular effects, particularly when used in high doses or if hypokalemia is present. For acute asthma exacerbations, the National Asthma Education and Prevention Program (NAEPP) Expert Panel recommends 4 to 8 puffs every 20 minutes for 3 doses, then 4 to 8 puffs every 1 to 4 hours as needed.

Close observation for such effects is prudent, particularly if beta-agonists are administered within 2 weeks of stopping the MAOI. Beta-agonists may be associated with adverse cardiovascular effects including QT interval prolongation, usually at higher doses, when associated with hypokalemia, or when used with other drugs known to prolong the QT interval. Protection lasts 2 to 3 hours in most patients. Beta-agonists may be associated with adverse cardiovascular effects including QT interval prolongation, usually at higher doses, when associated with hypokalemia, or when used with other drugs known to prolong the QT interval. Early consideration should be given to adding anti-inflammatory agents (e.g., corticosteroids) to the therapeutic regimen.

Beta-blockers will block the pulmonary effects of inhaled beta-agonists, and in some cases may exacerbate bronchospasm in patients with reactive airways. This risk may be more clinically significant with long-acting beta-agonists as compared to short-acting beta-agonists such as albuterol, levalbuterol, metaproterenol, pirbuterol, and terbutaline. In general, the National Asthma Education and Prevention Program (NAEPP) Expert Panel recommends albuterol 0.63 to 2.5 mg via oral inhalation every 4 to 6 hours as needed for symptoms of bronchospasm. Beta-agonists can sometimes increase heart rate or have other cardiovascular effects, particularly when used in high doses or if hypokalemia is present. Beta-agonists may be associated with adverse cardiovascular effects including QT interval prolongation, usually at higher doses and/or when associated with hypokalemia.
