title: [Pharmacokinetics of a new slow-release theophylline preparation in asthmatic children].
abstract: This study compares the pharmacokinetics of two preparations of slow-release theophylline, one of them already known, and the other one a new product (micronized), very well accepted by pediatric patients. Two similar groups of fifteen patients each all of then asthmatic children under ten years of age, were selected and given a single oral dose of 10 mg/kg of one of the preparations. The pharmacokinetic parameters (T 1/2, Kel, VD, Cl and AUC) did not differ between both groups. The new product could further be used more safely, due to its lower incidence of "erratic" behaviour.
