What the trial is, and whether it could suit you
The aim of this study is to investigate the pharmacokinetic and pharmacodynamic parameters of rivaroxaban and apixaban in patients with compensated liver cirrhosis (Child-Pugh class A and B).
The enrolled participants receive a prophylactic single oral dose of either rivaroxaban (10 mg) or apixaban (2.5 mg) at around 8 a.m. on the day of the trial. Blood samples are taken 0.5 hours pre-dose and 1, 2, 3, 4, 6, 8, 12 hours post-dose.
A follow-up telephone call is performed 5 days after the study intervention to collect safety data.
