1 A comparison of dabigatran etexilate with warfarin in patients with mechanical heart valves: The Randomized, phase II study to Evaluate the sAfety and pharmacokinetics of oraL dabIGatran etexilate in patients after heart valve replacemeNt (RE-ALIGN)  Frans Van de Werf, MD, Martina Brueckmann, MD, Stuart J.

2 Figure 1 Model-predicted probability of ischemic stroke and systemic embolic event versus trough plasma concentration of total dabigatran by age in atrial fibrillation subjects receiving either dabigatran etexilate 110 mg twice a day or dabigatran etexilate 150 mg twice a day in the RELY study.20 American Heart Journal  , e1DOI: ( /j.ahj ) Copyright © 2012 Mosby, Inc.

3 Figure 2 A, Median concentration-time profiles at steady state of each of the virtual patients with their respective target dose. A is depicting the median concentration-time profiles at steady state of each of the virtual patients with their respective target dose. In addition, the 80% prediction interval (10th to 90th percentiles) of the typical RE-LY patient receiving dabigatran 150 mg twice a day (reference exposure profile) is provided as shaded area. The simulation revealed that the median profiles are similar and overlap widely. All median profiles are within the 80% prediction interval, indicating a similar exposure. B, 80% prediction intervals (10th to 90th percentiles) of dabigatran trough concentrations at steady state in RE-ALIGN in comparison with observed concentrations in RE-LY.
