    Notizen: Summary Six healthy volunteers received an iv infusion of 317 mg lysine theophylline (equivalent to 197 mg anhydrous theophylline) in order to calculate theophylline clearance by standard methods. They subsequently received a 20 minute inhalation of nebulised lysine theophylline. Serum and salivary theophylline concentrations were measured and all saliva was collected for the first hour. From these concentrations estimates were made of the distribution of theophylline into the blood and saliva with 40% to 94% identified in the blood. Very high salivary concentrations were reached during the inhalation phase with saliva: serum concentration ratios of between 60 and 1600.

    Notizen: Summary Twenty volunteers aged between 20 and 57 years were given 197 mg of theophylline (as lysine theophylline) by iv infusion over 5 minutes to test the hypothesis that within the adult age range theophylline clearance declines with age. Samples were assayed for theophylline using the EMIT assay and clearance was determined by standard methods. Clearance values were 0.73 ml/min/kg below age 38 years and 0.75 ml/min/kg at and above age 38 years. Multiple regression analysis using age as a continuous variable showed no relationship between age and clearance.
