[Individualization of the dosage of oral theophylline with regular increase method and serum level control in 55 asthmatic children (author's transl)].

Authors have adjusted oral theophylline requirements in 55 asthmatic children, whose ages ranged from 19 months to 14 years, following a preconceived plan. The procedure is practical and useful. It's easily understood by parents and realizable in an ambulatory way. The average necessities of oral theophylline in children under nine years in their group have been lower than those signaled by other authors. This and the fact that oral requirements of theophylline in two pair of univitelin twins were identical, make the authors think that it is necessary probably to modificate protocols previously proposed for the different groups of population.
