2.8.2 Oral anticoagulants

           AMBER        Warfarin tablets 1mg, 3mg, 5mg
           AMBER        Acenocoumarol (nicoumalone) tablets 1mg (Sinthrome®)
         Novel oral anticoagulants (NOACs)      
           These drugs are relatively new to the market and the potential long‐term side effects are not yet fully known. Concerns also
           include that the optimal method of emergency reversal of the anticoagulant effects for all these agents is currently unclear
           in those patients who present with major bleeding. There are also concerns, highlighted by the MHRA regarding dabigatran
           use in renal insufficiency as exposure is substantially increased in these patients. The benefits of dabigatran and rivaroxaban
           over warfarin decline as INR control on warfarin increases. In patients where warfarin is well controlled (time in therapeutic
           range [TTR] >65%), the use of dabigatran or rivaroxaban may be less favourable.  On this basis, the use of these drugs should
           be implemented carefully and targeted to those patients that are likely to gain the most benefit from them  i.e. patients
           poorly controlled on warfarin or those eligible for, but choose not to be anti coagulated with warfarin. 
           An alert card is available in ELHE to clearly inform patients and healthcare professionals of key safety information regarding 
           the use of novel oral anticoagulants. All patients should be issued with this card.

          Deep vein thrombosis (DVT) and pulmonary embolism (PE) , and extended prevention of current DVT and PE in adults
          after initial treatment. 
          Rivaroxaban 10mg is recommended for treatment of Deep Venous thrombosis and Pulmonary Embolism, and extended
          prevention of recurrent DVT and PE in adults.
          When extended prevention of recurrent DVT and PE is indicated (following completion of at least 6 months therapy for DVT
          or PE), the recommended dose is 10 mg once daily. In patients in whom the risk of recurrent DVT or PE is considered high,                 such as those with complicated comorbidities, or who have developed recurrent DVT or PE on extended prevention with
          rivaroxaban 10 mg once daily, a dose of rivaroxaban 20 mg once daily should be considered. The duration of therapy and
          dose selection should be individualised after careful assessment of the treatment benefit against the risk of bleeding.

          Clinicians should consult the summary of product characteristics for further advice. Both products are likely to be used  
          initially for patients requiring extended prophylaxis following discharge, or in patients with needle phobia. All supplies will be
          prescribed and dispensed by the hospital, and GPs should not be asked to pick up or continue prescribing for these agents.
          Neither agent requires any anti-coagulant monitoring.
