Abstract | OBJECTIVE: METHODS: This was a prospective, parallel, open, matched-group study in which 24 subjects were enrolled ( renal insufficiency group, n = 12; healthy control group, n = 12). Blood samples of subjects administered 100 mg imrecoxib were collected at different time points and analyzed. Plasma concentrations of imrecoxib and its two metabolites (M1 and M2) were determined by the liquid chromatography-tandem mass spectrometry method, and pharmacokinetic parameters (clearance [CL], apparent volume of distribution [Vd], maximum (or peak) serum concentration [Cmax], amount of time drug is present in serum at Cmax [Tmax], area under the curve [AUC; total drug exposure across time], mean residence time [MRT] and elimination half-life [t1/2]) were calculated. RESULTS: The demographic characteristics of the two groups were not significantly different, with the exception of renal function. The mean Cmax and AUC0-t (AUC from time 0 to the last measurable concentration) of imrecoxib in the renal insufficiency group were 59 and 70%, respectively, of those of the healthy control volunteers with normal renal function, indicating a significant decline in the former group (P < 0. 05). The mean pharmacokinetic parameters of Ml in the renal insufficiency and healthy control groups did not significantly differ. In contrast, the mean Cmax and AUC0-t of M2 in the renal insufficiency group were 233 and 367%, respectively, of those of the normal renal function group, indicating a significant increase in the former group (P < 0.05). The mean CL/F (clearance/bioavailability) of M2 of the renal insufficiency group was 37% of that of the normal renal function group, indicating a notable reduction in the former group (P < 0.05). CONCLUSION:
