Research output: Contribution to journalArticlepeer-review


The pharmacokinetics of theophylline (1,3-DMX) and its metabolites were investigated in detail in four male rabbits after bolus intravenous injection (12 mg/kg) of the compound. Theophylline was measured in blood and urine, and its metabolites were determined only in urine. Apparent first-order rate constants for the metabolic processes involved in the formation of 1,3-DMX metabolites and their excretion in urine were calculated. An appropriate 13-compartment model was formulated to describe the disposition of 1,3-DMX and its metabolites.
