Albuterol is a bronchodialating beta-2 adrenergic agonist. Common brand names are ProAir, Ventolin, and Proventil. The most common use is for treating and preventing bronchospasms in patients with obstructive airway diseases. There are several dosage forms with the most common being metered dose inhalers (MDI) and dry powdered inhalers (DPI). Albuterol is generally considered a quick relief or rescue inhaler with dosing being 2 puffs by mouth every 4-6 hours as needed. Since albuterol specifically targets the beta-2 adrenergic receptor in bronchial smooth muscle there is little to no effect on heart rate. Although the drug is targeted it is still wise to monitor patients with heart issues. Common monitoring parameters are FEV1, peak flow, blood pressure, and heart rate.
