Data are shown as mean (±SD) except for Tmax values, which are presented as median (min–max).*Ratio = (LCZ696+warfarin)/LCZ696.
AUC, area under the plasma concentration-time curve; AUClast, AUC up to the last measurable concentration; AUCinf, AUC with the last concentration extrapolated; Cmax maximum (peak) concentration; CI, confidence interval; GMR, geometric mean ratio; Tmax, time to reach maximum (peak) concentration following drug administration; t1/2, half-life; SD, standard deviation.
