Insights
For pediatric asthma exacerbations, a daily dose of 0.5 mg/kg oral prednisolone is recommended. Higher doses of prednisolone showed no added benefits in recovery for children with acute asthma.
Area of Science:
- Pediatric Pulmonology
- Clinical Pharmacology
Background:
- Acute asthma exacerbations in children require effective treatment.
- Oral corticosteroids, like prednisolone, are a cornerstone of asthma management.
- Determining the optimal prednisolone dosage in pediatric patients is crucial for efficacy and safety.
Purpose of the Study:
- To investigate the appropriate dose of oral prednisolone for children hospitalized with acute asthma exacerbations.
- To compare the clinical outcomes of different prednisolone dosages in pediatric asthma patients.
Main Methods:
- A randomized, double-blind study involving 98 children (aged 1-15 years) with acute asthma exacerbations.
- Participants received daily doses of oral prednisolone at 0.5 mg/kg, 1.0 mg/kg, or 2.0 mg/kg, alongside nebulized bronchodilators.
- Clinical asthma scores, oxygen saturation, pulse rate, admission duration, and nebulizer use were assessed.
Main Results:
- No significant differences in recovery patterns were observed among the three treatment groups.
- Higher doses of prednisolone (1.0 mg/kg and 2.0 mg/kg) did not demonstrate superior efficacy compared to the 0.5 mg/kg dose.
- All measured clinical parameters showed similar improvements across all investigated prednisolone dosages.
Conclusions:
- The recommended dose of oral prednisolone for acute asthma exacerbations in children is 0.5 mg/kg/day.
- There is no clinical advantage to administering higher doses of prednisolone in this patient population.
- This finding supports a standardized, lower-dose regimen for effective pediatric asthma management.
Abstract:
Ninety-eight children aged 1-15 years entered a randomized double-blind study investigating an appropriate dose of oral prednisolone in children admitted to hospital with an acute exacerbation of asthma. None of the children had recently been treated with oral prednisolone. Following admission, the children were randomized to receive prednisolone 0.5 mg kg-1, 1.0 mg kg-1 or 2.0 mg kg-1 in a single daily dose in addition to nebulized bronchodilators. Clinical asthma scores, oxygen saturations, pulse rate, duration of admission and number of nebulizers given were compared in the three treatment groups. Thirty-five children received 0.5 mg kg-1, 33 received 1.0 mg kg-1 and 30 received 2.0 mg kg-1. There were no significant differences in the pattern of recovery between the three treatment groups. There were no advantages in using higher doses of prednisolone. We recommend 0.5 mg kg-1 day-1 of prednisolone as an appropriate dose for treating an acute exacerbation of asthma.
