Abstract
Objective: To study the pharmacokinetics of cetirizine/pseudoephedrine sustained release tablets in Beagle dogs. Methods: Pseudoephedrine concentrations in serum were assayed by HPLC with DiamonsilTM C18(250×4.6 mm,5μm) column, 0.05mol/L sodium dihydrogen phosphate-mathanol(75:25),pH adjusted to 3.0 with phosphoric acid as mobile phase,and detec- tion wavelength of 213nm.The pharmacokinetic parameters were researched after single admininstration of cetirizine/pseudoephedrine sustained release tablets in 6 Beagle dogs. Results: The pharmacokinetic parameters cetirizine/pseudoephedrine sustained release tablets were followed:MRT=8.21 h,Tpeak=4h,Cmax=200 8.7ng/mL.The relative hioavailabihy of cetirizine/pseudoephedrine sustained release tablets was(95.9±2.3)%. Conclusion: The pharmacokinetic profile of cetirizine/pseudoephedrine sustained release tablets was similar to the reference tablets.The self-made one was bioequivalent to Zycted-D 12h tablets,and its released profile in vivo/in vitro was correlation.
