Dabigatran represent a new class of promising anticoagulation agents. As an oral direct thrombin 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 Pradaxa® on different coagulation parameters.
This mono-centric, open-label study is undertaken to validate the effects of Dabigatran on coagulation parameters in plasma samples of 70 patients after hip or knee replacement surgery treated with Dabigatran 150-220 mg/d. Plasma samples are obtained by blood collection before, after 2 hours and after 12-14 hours after Dabigatran dosing in steady state (on 3rd - 5th day).

In patients with non-valvular atrial fibrillation treated with dabigatran etexilate, the level of adherence will be measured using a questionnaire, the Danish National Prescription Registr...

The purposes of this study are: 1. To evaluate the long-term safety of dabigatran etexilate 2. To assess the effect of a knowledge translation intervention on patient outcomes
Since its introduction in 1978, over 3.75 million babies have been born using in vitro fertilization (IVF). Maturing ovarian follicles lead to a large rise in estrogen to supra-physiologi...
Dabigatran etexilate is a novel oral anticoagulant. It is indicated in venous thromboembolic prevention in orthopedic surgery and has recently shown greater efficiency and tolerance as ant...
: Bleeding is the main complication of anticoagulant treatments as dabigatran etexilate. In patients with atrial fibrillation, dabigatran, at certain doses, has been associated with similar rates of s...
In patients who are receiving dabigatran, a direct oral anticoagulant, measuring the anticoagulant effect before surgery may be needed in certain circumstances. Although the dilute thrombin time (dTT)...
Calibrated automated thrombinography (CAT) is a sensitive method to assess coagulation. Dabigatran inhibits both free thrombin and the αmacroglobulin (αM)-thrombin complex, which results in an erron...
Many patients receiving dabigatran treatment might also require bisoprolol therapy. However, there is a possibility that bisoprolol as significant P-glycoprotein inhibitor might interact with dabigatr...
Idarucizumab, a fully humanized Fab antibody fragment, is indicated for reversal of dabigatran's anticoagulant activity. Idarucizumab neutralizes the anticoagulant effects of dabigatran by binding to ...
The highest dosage administered that does not produce toxic effects. The NOAEL will depend on how closely dosages are spaced (lowest-observed-adverse-effect level and no-observed-effect level) and the number of animals examined. The ultimate objective is usually to determine not the "safe" dosage in laboratory animals but the "safe" dosage for humans. Therefore, the extrapolation most often required of toxicologists is from high-dosage studies in laboratory animals to low doses in humans.

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.
An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
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.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
