ABSTRACT
Objective:
To study the pharmacokinetics of propranolol in Wistar rats after acute exposure to high altitude.Methods:
Fourteen male Wistar rats (200±20) g were selected. After administration of propranolol tablets (0.05 g/kg, i.g.), blood samples (3 mL) were collected at 0, 20, 40 min,1, 1.5, 2, 4, 6, 8, 12 and 24 h, respectively. The pharmacokinetic parameters were determined by LC-MS/MS and DAS 2.0 software.Results:
The main pharmacokinetic area under concentration-time curve (AUC), mean retention time (MRT), half-life (t1/2) and peak plasma concentration (Cmax) of propranolol were increased by 442.61%, 47.45%, 73.13%and 352.97%, respectively, whereas Tmax and clearance (CL) were decreased by 80.87%and 68.94%, respectively.Conclusion:
This study displays significant changes in the pharmacokinetics of propranolol under high altitude, which may provide evidence for clinical rational application of propranolol at high altitude.
