鹽酸曲馬多緩釋滴丸在比格犬體內(nèi)的藥動(dòng)學(xué)
[Abstract]:Aim: to study the pharmacokinetics and bioavailability of tramadol (Tr) sustained-release dropping pills in Beagle dogs. Methods Twenty six Beagle dogs were divided into two groups: male and female. Tr sustained-release pills and sustained release tablets were administered orally. The plasma concentrations of tramadol were determined by high performance liquid chromatography-ultraviolet (HPLC-UV). Results the Cmax of the two tablets were (273.34 鹵69.2) ng mL-1 and (244.02 鹵94.88) ng mL ~ (-1) mL-1, respectively, and (6.5 鹵0.84) h and (6.0 鹵0.89) h AUC _ (0-t) were (2 893.87 鹵811.40) ng h mL-1 and (2 505.99 鹵628.50) ng h ml ~ (-1), respectively. The relative bioavailability of the test and reference tablets was 97.2% 鹵13.6T, respectively. The 90% confidence interval of test preparation AUC0-24 was 96.4% and the 90% confidence interval of Cmax was 103.1% and 114.9%. Conclusion the results showed that the treatment of the two tablets in vivo was in accordance with the one-compartment model, and they were bioequivalent when given the same dose once.
