A comparative study of theophylline in a slow-release 'sprinkle' format with a standard syrup preparation in young
Insights
New slow-release theophylline sprinkles in children with asthma showed similar symptom control and compliance compared to liquid theophylline. However, the sprinkle formulation was linked to more side-effects and increased beta-agonist use.
Area of Science:
- Pediatric Pulmonology
- Pharmacology
- Clinical Therapeutics
Background:
- Asthma is a common chronic respiratory disease in children.
- Theophylline is a bronchodilator used in asthma management.
- Optimizing drug delivery and adherence is crucial for effective pediatric asthma care.
Purpose of the Study:
- To compare the efficacy and compliance of a new slow-release theophylline sprinkle formulation with conventional theophylline liquid in children with chronic asthma.
- To assess the incidence of side-effects and the need for rescue medication in both treatment groups.
Main Methods:
- A randomized controlled trial involving 61 children with chronic asthma.
- Participants received either theophylline sprinkles twice daily or theophylline liquid four times daily for three months.
- Outcomes measured included compliance, symptom control, side-effects, and use of beta-agonist nebulization.
Main Results:
- No significant difference in compliance or asthma symptom control was observed between the sprinkle and liquid theophylline groups.
- Patients receiving theophylline sprinkles experienced a higher incidence of side-effects.
- The sprinkle group showed increased utilization of beta-agonist nebulization, suggesting potentially poorer symptom control or more frequent exacerbations.
Conclusions:
- The slow-release theophylline sprinkle formulation offers comparable efficacy and compliance to liquid theophylline in pediatric asthma.
- The increased side-effect profile and higher beta-agonist use in the sprinkle group warrant further investigation.
- Alternative formulations or closer monitoring may be necessary for theophylline sprinkles in this population.
Abstract:
Sixty-one chronic asthmatic children received either a new slow-release sprinkle format of theophylline, twice daily, or theophylline liquid, 4-times per day. Over a study period of three months, there was no measurable difference in compliance or symptom control between the two groups. The sprinkle-treated patients, however, had a greater incidence of side-effects and had higher rates of nebulization with beta-agonists. Possible explanations are discussed.
