Salbutamol: tablets, inhalational powder, or nebuliser?
Insights
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.
Abstract:
A study was carried out to ascertain the most effective method of giving salbutamol. Seventeen children with severe asthma received active salbutamol (4 mg via a nebuliser, 400 micrograms as an inhalational powder, or a 4 mg tablet) together with complementary placebos on a double-blind, triple-dummy randomly allocated basis. The bronchodilatation effect was assessed by measuring the peak expiratory flow rate. The bronchodilatation effect was greatest when patients received nebulised salbutamol (p less than 0.05) but lasted longest when they received the tablet (p less than 0.0001); the onset of the effect was rapid with all forms of administration. These results indicate that nebulised salbutamol gives the best relief in severe asthma; in less severe cases, however, a regimen combining the inhalational powder and tablets is sufficient and more convenient.
