Due to the linear dose-response curves over a wide concentration range, a diluted TT assay can be used to accurately monitor both trough and maximum dabigatran levels. However, if oral anticoagulation stability could be more easily accomplished over time, individuals would suffer less adverse events and need less frequent blood settings. and adherence.

Atrial fibrillation (AF) is the most common tachyarrhythmia with prevalence of over 10% in older individuals (>70 years). AF is the leading cause of ischemic stroke, and stroke due to AF is one of the leading causes of death and adult disability. 2 Besides rate and rhythm control, stroke prevention is the key management strategy for individuals with nonvalvular atrial fibrillation and one or more additional risk factors for stroke.3 Thrombosis risk can be quantified using the CHADS2 or recently quantified CHA2DS2-VASc scores (documenting risk factors for stroke: history of congestive heart failure, hypertension history; age 75 [or age 65 years associated with one of the following: diabetes mellitus, coronary artery disease, or hypertension]; diabetes mellitus; stroke or transient ischemic assault or thromboembolism history; vascular disease history; sex) (observe also Table 1).4C6 By considering these additional risk factors the score is calculated to determine whether antithrombotic therapy is required or not. Current recommendations recommend oral anticoagulation having Picroside II a score of 2 or more. Table 1 Score systems evaluating thrombotic risk in individuals with atrial fibrillation

Anticoagulation with vitamin K antagonists (VKA), ever since their intro in the 1950s, has been an enduring platinum standard for stroke prevention in AF as well as for the prophylaxis and long-term treatment of venous thromboembolism.7,8 VKAs such as phenprocoumon (Marcumar?; MEDA Pharma GmbH & Co. KGaA, Bad Homburg, Germany) or warfarin (Coumadin?; Bristol-Myers Squibb GmbH & Co.

Due to the wide spectrum of food and drug relationships of VKAs, several pathological conditions, and the unpredictability of genetically identified interindividual variations in drug rate of metabolism, treatment with VKA requires more or less frequent monitoring of the anticoagulant effect with dose adjustment.9 Concerning the problems and down sides of these drugs with respect to efficacy, safety, and quality of life, many efforts have been undertaken to develop new anticoagulants focusing on only sole factors of the coagulation cascade. The licensed medicines rivaroxaban (Xarelto?; Bayer Pharma AG, Leverkusen, Germany), dabigatran (Pradaxa?; Boehringer Ingelheim GmbH, Ingelheim, Germany), and apixaban (Eliquis?; Bristol-Myers Squibb GmbH & Co.

Additional new substances focusing on factor Xa such as edoxaban (Lixiana?; Daiichi Sankyo Organization, Limited, Tokyo, Japan) are in final stages of medical studies. The predictability of these fresh oral direct anticoagulants is based on their pharmacodynamic and pharmacokinetic profiles. Unlike VKAs, multiple food and drug relationships are not seen with NOAC.The use of these two oral factor Xa inhibitors is not recommended in patients with creatinine clearance <15 mL/minute and are used with caution in patients with creatinine clearance between 15 and 29 mL/minute, as suggested in the summary characteristics of the products.33,34 Clinical case reports suggested that lower exposure of rivaroxaban or apixaban in individuals with high body weight (>120 kg) did not result in loss of drug efficacy.35 Dose adjustment based on low body weight may also not be warranted; however, combination of additional risk factors for bleeding (age 80 years, body weight 60 kg, and serum creatinine 1.5 mg/dL) might lead to dose adjustment. with focus on their use for prevention of embolic events in AF.

Atrial fibrillation (AF) may be the most common tachyarrhythmia with prevalence of over 10% in old sufferers (>70 years).
