To review the safety of anticoagulant therapies and supervision required To give recommendations for the inclusion of anticoagulants on the WHO Essential Medicines List 2. Review of indications for antithrombotic therapy in children Anticoagulant therapies are given for the prevention or treatment of venous and/or arterial thrombosis. The process of ‘development haemostasis’, whereby the proteins involved in coagulation change quantitatively and qualitatively with age across childhood, essentially protects children against thrombosis(1-5). For this reason, insults such as immobilization are unlikely to trigger the development of thrombotic diseases in children.

Chapter 4 Pharmacokinetics of Anticoagulant Rodenticides in Target and Non-target Organisms Katherine E. Horak, Penny M. Fisher, and Brian Hopkins 1 Introduction The concentration of a compound at the site of action is a determinant of its toxicity. This principle is affected by a variety of factors including the chemical properties of the compound (pKa, lipophilicity, molecular size), receptor binding affinity, route of exposure, and physiological properties of the organism. Many compounds have to undergo chemical changes, biotransformation, into more toxic or less toxic forms. Because of all of these variables, predicting toxic effects and performing risk assess- ments of compounds based solely on dose are less accurate than those that include data on absorption, distribution, metabolism (biotransformation), and excretion of the compound.

  • Doacs) and the Antidote Idarucizumab
    Update overview 2019 of reports on direct oral anticoagulants (DOACs) and the antidote idarucizumab Introduction Lareb previously published yearly overviews of reports (most recently in 2018) in consultation with the Medicines Evaluation Board CBG-MEB, concerning the direct oral anticoagulants (DOACs) dabigatran Pradaxa®, registered in the Netherlands in 2008 [1], rivaroxaban Xarelto®, registered in 2008 [2], apixaban Eliquis®, registered in 2011 [3] and edoxaban (Lixiana®), registered in 2015 [4-9]. The current overview provides a new yearly update of the reports received by Lareb for these DOACs. Furthermore, reports received by Lareb for the antidote idarucizumab are described in this overview. Idarucizumab is a specific antidote for dabigatran and was registered in the Netherlands in 2015 [10]. For this overview, data from the national ADR database were used. These data include reports with serious outcome from the Lareb Intensive Monitoring System (LIM). The DOACs have been monitored with the LIM methodology since September 2012. Prescription data The number of patients using DOACs in the Netherlands according to the GIP database is shown in table 1 [11]. These data are based on extramurally provided medication included in the Dutch health insurance package. Because the antidote idarucizumab is administered in the hospital and not reimbursed directly via the healthcare insurance, these data are not available for this drug. The number of reports received by the Netherlands Pharmacovigilance Centre Lareb per year since 2013 for each DOAC, is also shown in table 1. Furthermore, table 1 shows the calculated number of these reports per 1.000 users according to the GIP database. As noted before, the data from the GIP database represent reimbursed medicines and these may differ from actually prescribed medicines.

  • Heparin-Induced Thrombocytopenia (Hit)
    HEPARIN‐INDUCED THROMBOCYTOPENIA (HIT) OBJECTIVE: To assist clinicians with the diagnosis and initial management of heparin‐induced thrombocytopenia (HIT) and suspected HIT. BACKGROUND: HIT is a transient, immune‐mediated adverse drug reaction in patients recently exposed to heparin that generally produces thrombocytopenia and often results in venous and/or arterial thrombosis. HIT occurs in up to 5% of patients receiving unfractionated heparin (UFH) and in <1% who receive low molecular weight heparin (LMWH). HIT is characterised by immunoglobulin G (IgG) antibodies that recognize an antigen complex of platelet factor 4 (PF4) bound to heparin. These antibodies trigger a highly prothrombotic state by causing intravascular platelet aggregation, intense platelet, monocyte and endothelial cell activation and excessive thrombin generation. CLINICAL FEATURES: HIT typically presents with a fall in platelet count with or without venous and/or arterial thrombosis. Thrombocytopenia: A platelet count fall >30% beginning 5‐10 days after heparin exposure, in the absence of other causes of thrombocytopenia, should be considered to be HIT, unless proven otherwise. A more rapid onset of platelet count fall (often within 24 hours of heparin exposure) can occur when there is a history of heparin exposure within the preceding 3 months. Bleeding is very infrequent. Thrombosis: HIT is associated with a high risk (30‐50%) of new venous or arterial thromboembolism. Thrombosis may be the presenting clinical manifestation of HIT or can occur during or shortly after the thrombocytopenia. Other clinical manifestations of HIT: Less frequent manifestations include heparin‐induced skin lesions, adrenal hemorrhagic infarction, transient global amnesia, and acute systemic reactions (e.g. chills, dyspnea, cardiac or respiratory arrest following IV heparin bolus).

It is similarly effective to the other DOAC options but costs considerably less Clinical experts in Tayside are supporting the use of edoxaban All newly diagnosed NV-AF patients will be started on edoxaban as 1st choice for those unsuitable for warfarin Existing patients already on a DOAC for NV-AF are to be reviewed and considered for switch to edoxaban This will help to ensure that the money available to spend on medicines is being used appropriately Is edoxaban as good as the other DOACs? Yes, the evidence is that it is as effective as warfarin and the other DOACs. It is licensed for this indication and has been recommended by the Scottish Medicines Consortium Other Scottish Health Boards are also considering the use of edoxaban A recent Health Improvement Scotland (HIS) summary (http://www.healthcareimprovementscotland.org/our_work/cardiovascular_dis ease/programme_resources/doac_review_report.aspx) is consistent with this Tayside switch recommendation Lead clinicians from cardiology, stroke, vascular medicine, relevant MCN’s and haematology are all supportive of this Tayside guidance on the basis of current evidence Will we need to do a further switch if the price of other DOACs falls?

  • DOACS COMPARISON and Faqs
    NOACS/DOACS*: PRACTICAL ISSUES AND FREQUENTLY-ASKED QUESTIONS OBJECTIVES: • To summarize characteristics of the direct oral anticoagulants (DOACs) currently available in Canada. • To address common practical issues related to DOAC use. • To address frequently asked questions regarding DOACs. BACKGROUND: The DOACs, which consist of apixaban, dabigatran, edoxaban, and rivaroxaban are used for the prevention and treatment of venous thromboembolism (VTE) and for stroke prevention in atrial fibrillation (AF). Practical advantages of DOACs over warfarin include fixed once- or twice-daily oral dosing without the need for coagulation test monitoring, relatively fewer known drug interactions and no known food interactions. Like warfarin, DOACs increase the risk for bleeding and should be administered under close clinical monitoring. Practical issues regarding the everyday use of DOACs will be addressed in this guide. PRACTICAL AND LIFESTYLE ISSUES: Can DOACs be taken with meals? Rivaroxaban should be taken with meals to enhance absorption; the tablet can be crushed and taken with soft foods such as applesauce. Apixaban, dabigatran, edoxaban can be taken with or without meals. However, taking dabigatran with meals can reduce dyspepsia. Dabigatran capsules should not be opened, broken or chewed before swallowing. Are there any foods or beverages that need to be avoided with DOACs? Unlike with warfarin, there are no known food interactions with DOACs, so there are no food restrictions when taking these medications. In addition, there is no evidence that drinking grapefruit juice affects the effectiveness or safety of DOACs. In general, it is acceptable for patients taking a DOAC to drink alcoholic beverages in moderation (e.g. a glass of wine with a meal) as it is for patients on warfarin.

Thus, a comprehensive wastewater treatment plant and surface water monitoring campaign was conducted at two urban catchments in Germany in 2018 and 2019 to investigate potential emission sources of ARs into the aquatic environment. Over several months, the occurrence and fate of all eight ARs authorized in the European Union as well as two pharmaceutical anticoagulants was monitored in a variety of aqueous, solid, and biological environmental matrices during and after widespread sewer baiting with AR-containing bait. As a result, sewer baiting in combined sewer systems, besides outdoor rodent control at the surface, was identified as a substantial contributor of these biocidal active ingredients in the aquatic environment. In conjunction with heavy or prolonged precipitation during bait application in combined sewer systems, a direct link between sewer baiting and AR residues in wastewater treatment plant influent, effluent, and the liver of freshwater fish was established.
