title: Theophylline half-life in infants and young children.
abstract: Pharmacokinetics of theophylline elimination were studied in a 54-child population. Subjects' ages ranged from three months to six years. The mean half life was 4.92 hours, with S.D. +/- 1.88 hours. This is at variance with previous reports. Ages and half lives were compared and there were no correlations in this young age group.
