Albuterol is a widely prescribed bronchodilator that offers targeted relief for respiratory conditions characterized by coughing, wheezing, and airway constriction. It is particularly effective in managing acute symptoms of bronchitis and croup, where inflammation and mucus production impair breathing. By relaxing the muscles around the airways, albuterol helps open constricted bronchial tubes, facilitating easier airflow and reducing cough severity. This medication is available in various forms, including inhalers and nebulizer solutions, allowing for flexible administration based on patient needs and clinical context.
Features
- Fast-acting bronchodilator providing relief within minutes
- Available in multiple formulations: metered-dose inhaler (MDI), dry powder inhaler (DPI), and nebulizer solution
- Targets beta-2 adrenergic receptors in the lungs to promote smooth muscle relaxation
- Reduces airway resistance and improves oxygen exchange
- Compatible with spacer devices for improved delivery, especially in pediatric populations
Benefits
- Rapid symptom relief during acute bronchospasm episodes
- Decreased coughing frequency and intensity in bronchitis and croup
- Improved exercise tolerance and daily activity engagement
- Enhanced quality of sleep by reducing nighttime coughing
- Lower risk of hospitalization when used appropriately in exacerbations
- Supports faster recovery when integrated into a comprehensive treatment plan
Common use
Albuterol is primarily indicated for the treatment and prevention of bronchospasm in patients with reversible obstructive airway diseases, such as asthma and chronic obstructive pulmonary disease (COPD). Its use extends to acute management of bronchitis—particularly acute bronchitis where bronchospasm is a component—and croup (laryngotracheobronchitis) in pediatric patients. In bronchitis, albuterol helps alleviate coughing and wheezing by reducing airway constriction and improving mucus clearance. For croup, nebulized albuterol may be used adjunctively to reduce subglottic edema and stridor, though corticosteroids remain first-line. Off-label uses may include cough-variant asthma and bronchiectasis exacerbations.
Dosage and direction
Dosage varies by formulation, age, and clinical indication. For adults using a metered-dose inhaler (MDI), the typical dose is 1–2 inhalations every 4–6 hours as needed for symptoms, not exceeding 8 inhalations in 24 hours. For nebulizer solutions, the common dose is 2.5 mg administered three to four times daily. Pediatric dosing is weight-based: 0.1–0.15 mg/kg per dose via nebulizer (minimum 1.25 mg, maximum 2.5 mg), up to every 4–6 hours. For croup, dosing may be more frequent under medical supervision. Always shake the inhaler well before use, and prime it if unused for >2 weeks. Use a spacer with MDIs to improve lung deposition, especially in children. Rinse mouth after inhalation to reduce systemic absorption and side effects.
Precautions
Use albuterol cautiously in patients with cardiovascular disorders (e.g., hypertension, arrhythmias), diabetes, hyperthyroidism, or seizure disorders due to potential sympathetic stimulation. Monitor for paradoxical bronchospasm—if wheezing increases after use, discontinue and seek alternatives. Avoid excessive use, as it may lead to tolerance and reduced efficacy. Pulmonary and cardiovascular parameters should be assessed periodically in long-term users. In elderly patients, consider lower initial doses due to increased sensitivity to beta-agonists. Pregnancy Category C: use only if potential benefit justifies potential risk to the fetus.
Contraindications
Albuterol is contraindicated in patients with known hypersensitivity to albuterol or any component of the formulation. It should not be used in cases of tachyarrhythmias or preexisting severe cardiac disease uncontrolled by medication. Caution is advised in patients using monoamine oxidase inhibitors (MAOIs) or tricyclic antidepressants due to increased cardiovascular risk.
Possible side effect
Common side effects include tremor, nervousness, headache, tachycardia, palpitations, and dry mouth. Less frequently, patients may experience muscle cramps, insomnia, dizziness, or nausea. Paradoxical bronchospasm (worsening breathing) occurs rarely but requires immediate discontinuation. Hypokalemia may occur at high doses, particularly in susceptible individuals. Allergic reactions such as rash or angioedema are uncommon but possible.
Drug interaction
Beta-blockers (e.g., propranolol) may antagonize albuterol’s effects and should be avoided. Concomitant use with other sympathomimetic agents (e.g., decongestants) may increase cardiovascular side effects. Diuretics and corticosteroids can potentiate hypokalemia. MAOIs and tricyclic antidepressants may enhance adrenergic effects. Use with xanthine derivatives (e.g., theophylline) may increase the risk of adverse effects.
Missed dose
If a scheduled dose is missed, administer it as soon as remembered unless it is nearly time for the next dose. Do not double the dose to catch up. For as-needed use, this is not applicable.
Overdose
Overdose may manifest as exaggerated side effects: angina, hypertension, hypokalemia, seizures, and cardiac arrest. Treatment is supportive and may include cardioselective beta-blockers (e.g., metoprolol) under careful monitoring, as non-selective blockers can worsen bronchospasm. Seek immediate medical attention.
Storage
Store at room temperature (15–30°C), away from light and moisture. Do not puncture or incinerate the canister. Keep out of reach of children. Discard canister after labeled number of inhalations or if it appears empty.
