Salbutamol: tablets, inhalational powder, or nebuliser?
British Medical Journal (Clinical Research Ed.)
|January 10, 1981
Summary
Nebulized salbutamol provides the quickest relief for severe asthma attacks. For less severe cases, a combination of inhalational powder and tablets offers convenient and sufficient bronchodilation.
Area of Science:
- Pediatric Pulmonology
- Clinical Pharmacology
Background:
- Asthma management in children requires effective bronchodilator delivery.
- Salbutamol is a primary treatment for acute asthma exacerbations.
Purpose of the Study:
- To compare the efficacy and duration of bronchodilation from different salbutamol administration methods in children with severe asthma.
Main Methods:
- A double-blind, triple-dummy, randomized trial involving 17 children with severe asthma.
- Salbutamol was administered via nebulizer (4 mg), inhalational powder (400 mcg), or tablet (4 mg).
- Peak expiratory flow rate (PEFR) was used to assess bronchodilation.
Main Results:
- Nebulized salbutamol demonstrated the greatest bronchodilating effect (p<0.05).
- Salbutamol tablets provided the longest duration of bronchodilation (p<0.0001).
- Rapid onset of bronchodilation was observed across all administration routes.
Conclusions:
- Nebulized salbutamol is most effective for severe asthma relief.
- For less severe asthma, a combination of inhalational powder and tablets is a convenient and effective alternative.
