Abstract:
AIM:To evaluate the bioequivalence of the two rivaroxaban tablets in Chinese healthy subjects.METHODS:Twenty-eight subjects under fasting status and twenty-eight subjects under fed status were enrolled in the study.This study was designed as a four period,fully repetitive,cross-over study.All subjects were administered test(T)and reference(R)rivaroxaban tablets(10 mg)un-der fasting and fed condition respectively.Liquid chromatography-tandem mass spectrometry was used to detect the concentrations of rivaroxaban in plasma.WinNonlin 7.0 was used to calculate the main pharmacokinetic parameters(PK)and to eval-uate the bioequivalence.RESULTS:In fasting group,the main pharmacokinetic parameters of T and R preparation were as follows:Cmax were(186.57±56.41)and(187.61±50.89)ng/mL;AUC0-t were(1 156.21±335.85)and(1 177.59±343.72)h·ng·mL-1;AUC0-∞ were(1 235.77±384.03)and(1223.53±392.10)ng·h·mL-1.The 90%confidential interval(CI)of the three main parameters were 90.81%-105.67%,92.83%-103.85%and 95.04%-107.13%.The upper limit of the 90%CI for the test-to-reference ratio of the within-subject of Cmax,AUC0-t and AUC0-∞ were 1.56,1.41 and 1.73.In fed group,the main pharmacokinetic parameters of T and R preparation were as follows:Cmax were(207.81±45.26)and(211.04±36.62)ng/mL;AUC0-t were(1 271.26±260.92)and(1 233.23±201.85)h·ng·mL-1;AUC0-∞ were(1 290.76±264.90)and(1251.68±203.73)ng·h·mL-1.The 90%CI of the three main parameters were 92.82%-102.28%,97.68%-106.68%and 97.71%-106.68%.The upper limit of the 90%CI for the test-to-reference ratio of the within-subject of Cmax,AUC0t and AUC0-∞were 1.76,1.47 and 1.47.CONCLUSION:The two preparations of rivaroxaban tablets were bioequiva-lent.
