Discuss problems and limitations of warfarin and heparin therapy‚ and show how these might be overcome by the new generation of direct oral anticoagulants. Anticoagulant drugs are used to prevent thrombosis in patients at long-term risk‚ in non-thrombotic patients when a high risk situation occurs and to treat established thromboembolism. The main anticoagulant drugs currently in use in the UK are warfarin‚ heparin and various analogues of heparin. These drugs are effective in the treatment and

Heparin: this is given as a daily injection under the skin‚ for an average of 3-5 days‚ and has a rapid effect. Warfarin: this is given in tablet form and is the long term treatment. Warfarin takes a few days to have its full effect‚ so this is why Heparin injections are also given at first. The duration of the Warfarin treatment will depend on the location of your thrombosis. The dose of Warfarin will vary from patient to patient. Regular blood samples will be required daily at first‚ and then throughout

recommendations when preparing and eating foods. Account for all foods and beverages consumed‚ and assess how they fit eaten pattern. Select eaten pattern that meets nutrient needs at an appropriate calorie level. Anticoagulation medication such as Warfarin act to reduce the overall production of blood clotting factors. Anticoagulants do not dissolve blood clots‚ but they prevent clots from getting bigger. Anticoagulants benefits are: They protect patients from heart attack and stroke. Ensure blood

Fibrillation and Oral Anticoagulation Scenario You are the nurse working in an anticoagulation clinic. K.N. is a patient who has a longstanding irregularly irregular heartbeat (atrial fi brillation‚ or A-fi b) for which he takes the oral anticoagulant warfarin (Coumadin). Recently‚ K.N. had his mitral heart valve replaced with a mechanical valve. You know that there are different PT/INR (prothrombin time/International Normalized Ratio) goal recommendations based on the indication for anticoagulation. (NOTE:

will receive anticoagulation. This is accomplished by several different medications: 1) heparin‚ 2) warfarin and 3) low-molecular-weight heparins. These medications are generally continued for 3-6 months. Patients that have had multiple thromboembolic episodes or are at high risk of further episodes (for example‚ multiple deficiencies) may be considered for long-term oral anticoagulation (warfarin). Because studies have demonstrated an increased risk of recurrent venous thromboembolic disease in
