Abstract/OtherAbstract:
AIM: This study investigated the effects of hepatic impairment on the pharmacokinetics and pharmacodynamics of a single dose of rivaroxaban (10 mg), an oral, direct Factor Xa inhibitor. METHODS: This single-centre, non-randomized, non-blinded study included subjects with mild (n = 8) or moderate hepatic impairment (n = 8), according to the Child-Pugh classification, and gender-matched healthy subjects (n = 16). RESULTS: Rivaroxaban was well tolerated irrespective of hepatic function. Mild hepatic impairment did not significantly affect the pharmacokinetics or pharmacodynamics of rivaroxaban, compared with healthy subjects. However, in subjects with moderate hepatic impairment, total body clearance was decreased, leading to a significant increase in area under the plasma concentration-time curve (AUC). The least-squares (LS)-mean values for AUC were 1.15-fold (90% confidence interval [CI] 0.85-1.57) and 2.27-fold (90% CI 1.68-3.07) higher in subjects with mild and moderate hepatic impairment, respectively, than in healthy subjects. Consequently, the pharmacodynamic responses were significantly enhanced in subjects with moderate hepatic impairment. For inhibition of Factor Xa, increases in the area under the effect-time curve and the maximum effect were observed, with LS-mean ratios of 2.59 and 1.24, respectively, versus healthy subjects. Prolongation of prothrombin time was similar in healthy subjects and those with mild hepatic impairment, but was significantly enhanced in those with moderate hepatic impairment.
