Yuh-Jing Lin,Yann-Huei Phillip Lee,William R Ravis*

Objectives: To investigate the pharmacokinetics of Carbamazepine (CBZ) in rats during growth hormone treatment. Methods: Recombinant Human Growth Hormone (rhGH) was injected subcutaneously at a daily dose of 0.1 mg/ kg, 2 mg/kg, or phosphate buffered saline (control) for 5 days in male Sprague-Dawley rats. On day 6, a dose of 25 mg/kg of CBZ was injected intravenously via a jugular vein cannula into the rat. Growth rate were compared between treatment groups. The pharmacokinetics of CBZ was determined from its concentrations in rats? blood and urinary samples. Results: Over the 5-day treatment period, growth rate were greater than control for the 2 mg/kg rhGH dosed group. The volume of distribution (Vss) was significantly (p
