A Prospective Pharmacodynamic Study of Rivaroxaban

August 1, 2014 updated by: Suzanne J. Francart, PharmD, CPP, University of North Carolina, Chapel Hill

A Prospective Pharmacodynamic Study of Rivaroxaban Using Peak and Trough Coagulation Test Results in Patients on Therapeutic Doses of Rivaroxaban

The ability to explain bleeding or clotting complications in patients treated with rivaroxaban remains challenging. In addition, there is limited data on how coagulation tests perform in patients treated with therapeutic doses of rivaroxaban. Predicted responses of coagulation tests to therapeutic doses of rivaroxaban may be helpful in better understanding abnormal responses to rivaroxaban. The purpose of the study is to define a therapeutic reference range for peak and trough coagulation tests in patients taking FDA approved doses of rivaroxaban and to determine which tests may be most clinically useful for monitoring rivaroxaban.
