Abstract:
OBJECTIVE: To study the pharmacokinetics of domestic carvedilol and relative bioavailability of carvedilol capsule in Chinese volunteer.METHODS: Eight volunteers orally took a single dose of 30mg test preparation and 25mg control preparation in a random crossover and self-control method.Samples were determined by RP-HPLC fluorescent method.RESULTS: Profiles of carvedilol in vivo could be described as open two-compartment model.The main pharmacokinetics parameters of test and control preparations were as follows: Cmax(98.89± 27.60) ng/ml、 (70.06± 27.29) ng/ml, Tmax(0.4 849± 0.2 635) h、 (0.6 037± 0.1 707) h, CL(0.1 621± 0.08 057) (mg· h) /(ng· ml) 、 (0.1 796± 0.09 198) (mg· h) /(ng· ml) , V/F(c)(0.2 127± 0.1 260) mg/(ng· ml)、 (0.2 777± 0.1 860) mg/(ng· ml) , T1/2β (2.011± 1.709) h、 (1.959± 1.156) h, AUC(233.1± 97.12) ng/(ml· h) 、 (168.0± 70.61) ng/(ml· h) ; Mean relative bioavailability in man was (111.3± 15.18)% .CONCLUSION: The results can be used for design of therapeutic scheme.
