To compare the changes in the pharmacokinetic/pharmacodynamic (PK/PD) profiles of Chiglitazar Sodium between healthy rats and those with hypoalbuminemia, and to evaluate the medication safety of Chiglitazar in rats with hypoalbuminemia.
Methods
Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) method was employed to determine the plasma concentration ofChiglitazar Sodium in both healthy rats and rats with hypoalbuminemia after administration. Pharmacokinetics were calculated based on the measured data. Blood glucose levels were monitored and recorded in both groups to observe pharmacodynamic changes.
Results
Pharmacokinetic analysis revealed that, compared to the healthy group, only the T max in the hypoalbuminemia group was significantly earlier by 34.3% (P<0.001), while other pharmacokinetic parameters showed no significant differences. Pharmacodynamic studies indicated that blood glucose levels remained stable in both healthy rats and rats with hypoalbuminemia during the 0.25–10 hour monitoring period.
Conclusion
Except for T max , there were no significant differences in PK/PD parameters between rats with hypoalbuminemia and healthy rats. Blood glucose levels remained stable in both groups after oral administration of Chiglitazar Sodium. The animal experimental results suggest that, under normal conditions, hypoalbuminemia does not affect the pharmacokinetic and pharmacodynamic profiles of Chiglitazar Sodium.
