Insights
A single dose of inhaled budesonide with salbutamol effectively reduced asthma symptoms in children. However, oral prednisone showed a faster increase in hemoglobin saturation compared to budesonide.
Area of Science:
- Pediatric Pulmonology
- Clinical Pharmacology
- Respiratory Medicine
Background:
- Acute asthma exacerbations in children require prompt and effective treatment.
- Inhaled corticosteroids and oral corticosteroids are common treatment options.
- Comparing the efficacy of different delivery methods and agents is crucial for optimizing care.
Purpose of the Study:
- To compare the efficacy of a single dose of inhaled budesonide versus oral prednisone in pediatric patients with acute asthma.
- To evaluate symptom severity and hemoglobin saturation changes following treatment.
Main Methods:
- A randomized, double-blind, placebo-controlled trial involving 49 children (2-7 years) with acute asthma.
- Participants received nebulized salbutamol followed by either placebo, oral prednisone, or nebulized budesonide.
- Clinical outcomes assessed included symptom scores and transcutaneous hemoglobin saturation.
Main Results:
- All treatment groups showed progressive clinical improvement.
- Oral prednisone led to a significant increase in hemoglobin saturation after 2 hours.
- Nebulized budesonide showed a significant increase in hemoglobin saturation after 4 hours, while placebo took 24 hours.
Conclusions:
- Single-dose nebulized budesonide combined with salbutamol may be comparable to oral prednisone in improving asthma symptom severity.
- Oral prednisone demonstrated a more rapid improvement in hemoglobin saturation.
- Further research may explore optimal dosing and delivery strategies for inhaled corticosteroids in acute pediatric asthma.
Objective:
To investigate the efficacy of a single dose of inhaled budesonide as compared to oral prednisone in patients with acute asthma.
Methods:
Randomized double-blind, double-dummy and placebo-controlled clinical trial. Forty-nine children aged 2 to 7 years with acute asthma were randomized in three groups after receiving nebulized salbutamol (0.15 mg/kg). Group I received placebo both as tablets and nebulization, group II was treated with a single dose of oral prednisone (1 mg/kg) and inhaled placebo, and group III received a single dose of placebo tablet and nebulized budesonide (2 mg). Patients were evaluated in terms of symptom score and transcutaneous hemoglobin saturation. Nebulized salbutamol was repeated in case of increasing symptom score or lower saturation.
Results:
Progressive clinical improvement was observed in all three groups. However, a significant increase in hemoglobin saturation was observed after 2 hours with prednisone, 4 hours with budesonide, and 24 hours with placebo.
Conclusion:
A combination of single-dose nebulized budesonide and salbutamol may be as effective as oral prednisone to improve symptom severity, but the latter increases hemoglobin saturation in exacerbation of asthma.

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
