A comparative study of theophylline in a slow-release 'sprinkle' format with a standard syrup preparation in young children with asthma.

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.
