For albuterol sulfate (Proair HFA), give: Class, Action, Uses,
Side Effects, Interactions, and Dose. Correct Answer Class:
Beta 2 agonist
Action: Activates beta 2 adrenergic receptors on airway smooth
muscle, resulting in relaxation of smooth muscle of all airways,
from the trachea to terminal bronchioles
Uses: Treatment or prevention of bronchospasm in patients with
reversible obstructive airway disease; prevention of exercise-
induced bronchospasm
Side Effects: Pharyngitis, headache, rhinitis, dizziness, pain,
tachycardia
Interactions: Caution with additional adrenergic drugs
administered by any route; use cardioselective beta blockers
with caution; extreme caution with MAOIs, TCAs; ECG
changes and/or hypokalemia caused by diuretics may be
worsened

,Dose: 1-2 inhalations every 4-6 hours
