Graduation date: Pharmacokinetics of theophylline and N-7 substituted\ud theophylline in rabbits when administered alone and in\ud various combinations were investigated. This thesis has\ud four chapters dealing with etophylline and theophylline;\ud proxyphylline and theophylline; dyphylline and theophylline;\ud and etophylline.   On the contrary, in rabbits with alimentary induced lipid metabolism disturbancest 1/2 of theophylline was practically unchanged and AUC only slightly increased. In conclusion: (1) hyperlipidemia affects the pharmacokinetics of theophylline in human beings, (2) rabbit model with dietetary induced lipid metabolic disturbances is not a suitable Cited by: 6.   Zuidema with others (Ufkes et al., "Efficacy of Theophylline and its NSubstituted Derivatives in Experimentally Induced Bronchial Asthma in the Guinea-Pig", Arch.

Theophylline data in 5 of 6 rabbits for Treatment 3 were best described (Table 1) by a two-compartment open model with a mean r^ of h and mean Vd^^ of liter/kg.

AN ABSTRACT OF THE THESIS OF WATTANAPORN TAVIPATANA for the degree of Master of Science in Pharmacy presented on Ap Title: Pharmacokinetics of Theophylline and its N-7 Derivatives in Rabbits. Theophylline is a methylxanthine derivative commonly used in the treatment of small airway disease. It is a bronchodilator, but also increases mucociliary clearance. It is a mild positive inotrope and has mild diuretic properties. The pharmacokinetics of theophylline have been studied in detail in rabbits (May and Jarboe, ). Theophylline (1,3-dimethylxanthine) was incubated with human liver microsomes in the presence of enoxacin, ciprofloxacin, norfloxacin, or ofloxacin. Theophylline, its demethylated metabolites (3-methylxanthine and 1-methylxanthine), and its hydroxylated metabolite (1,3-dimethyluric acid) were measured by high-pressure liquid chromatography, and.
