Effect of Rivaroxaban on Coagulation Parameters- an ex Vivo Study

2014-08-27 03:18:58 | BioPortfolio


Rivaroxaban represent a new class of anticoagulation agents. As an oral direct factor Xa inhibitor it has been effective in preventing venous thromboembolism in patients undergoing elective orthopaedic surgery. This ex vivo study is undertaken to investigate the ex-vivo effects of Xarelto® on different coagulation parameters.


To validate the effects of Rivaroxaban on coagulation parameters plasma samples of patients after hip or knee replacement surgery treated with Rivaroxaban 10 mg/d are investigated.

Plasma samples are obtained by blood collection before, after 2 hours and after 12 hours after Rivaroxaban dosing in steady state (on 3rd - 5th day).

Several techniques, including clot-based tests, chromogenic assays and ELISA´s are used for coagulation assays in our coagulation laboratory Frankfurt/Main. The influence of Rivaroxaban on different coagulation assays should be investigated in our coagulation laboratory.

Medical and Biotech [MESH] Definitions

A principle of estimation in which the estimates of a set of parameters in a statistical model are those quantities minimizing the sum of squared differences between the observed values of a dependent variable and the values predicted by the model.

Laboratory tests for evaluating the individual's clotting mechanism.

Methods of investigating the effectiveness of anticancer cytotoxic drugs and biologic inhibitors. These include in vitro cell-kill models and cytostatic dye exclusion tests as well as in vivo measurement of tumor growth parameters in laboratory animals.

The identification of selected parameters in newborn infants by various tests, examinations, or other procedures. Screening may be performed by clinical or laboratory measures. A screening test is designed to sort out healthy neonates (INFANT, NEWBORN) from those not well, but the screening test is not intended as a diagnostic device, rather instead as epidemiologic.

A rigorously mathematical analysis of energy relationships (heat, work, temperature, and equilibrium). It describes systems whose states are determined by thermal parameters, such as temperature, in addition to mechanical and electromagnetic parameters.
