  1. Class
    Sympathomimetic, bronchodilator
  2. Mechanism of Action
    Selective beta-2 agonist that stimulates adrenergic receptors of the sympathomimetic nervous system resulting in smooth muscle relaxation in the bronchial tree and peripheral vasculature.
  3. Indications
    Treatment of bronchospasm in patients with reversible obstructive airway disease (COPD,asthma). Prevention of exercise-induced bronchospasm.
  4. Contraindications
    Known prior hypersensitivity reactions to albuterol. Tachycardia arrhythmias, especially those caused by digitalis. Synergistic with other sympathomimetics.
  5. Adverse Reactions
    Often dose-related and include restlessness, tremors, dizziness, palpitations, tachycardia, nervousness, peripheral vasodilation, nausea, vomiting, hyperglycemia, increased blood pressure, and paradoxical bronchospasm.
  6. Drug interactions
    Tricyclic antidepressants may potentiate vasculature effects. Beta blockers are antagonistic. May potentiate hypokalemia caused by diuretics.
  7. How supplied
    • Solution for aerosolization: 0.5% (5mg/ml).
    • Metered dose inhaler: 90 mcg/metered spray (17-g canister with 200 inhalations).

    • Pediatric: Administer solution of 0.01-0.03 ml (0.05-0.15 mg/kg/dose diluted in 2 ml of 0.09% normal saline. May repeat every 20 minutes three times.
  9. Duration of action
    • Onset: in 5-15 minutes with
    • Peak effect: in 30 minutes to 2 hours and
    • Duration: of 3-4 hours.
