  • MIRADON FPO Brand of Anisindione Tablets
    R 1 2 3 4 5 3 4 F-16099775 1898 ® MIRADON FPO brand of anisindione Tablets DESCRIPTION MIRADON Tablets contain a syn- thetic anticoagulant, anisindione, an indanedione derivative. Each tablet contains 50 mg anisin- dione. They also contain: corn starch, FD&C Red No. 3, gelatin, lactose, and hydrogenated cotton- seed oil. ACTIONS Like phenindione, to which it is re- lated chemically, anisindione exercises its thera- peutic action by reducing the prothrombin activity of the blood. INDICATIONS Anisindione is indicated for the prophylaxis and treatment of venous thrombosis and its extension, the treatment of atrial fibrilla- tion with embolization, the prophylaxis and treat- ment of pulmonary embolism, and as an adjunct in the treatment of coronary occlusion. CONTRAINDICATIONS All contraindications to oral anticoagulant therapy are relative rather than absolute. Contraindications should be evaluated for each patient, giving consideration to the need for and the benefits to be achieved by anticoagu- lant therapy, the potential dangers of hemor- rhage, the expected duration of therapy, and the quality of patient monitoring and compliance. Hemorrhagic Tendencies or Blood Dyscrasias: In general, oral anticoagulants are contraindi- cated in patients who are bleeding or who have hemorrhagic blood dyscrasias or hemorrhagic tendencies (eg, hemophilia, polycythemia vera, purpura, leukemia) or a history of bleeding dia- thesis. They are contraindicated in patients with recent cerebral hemorrhage, active ulceration of the gastrointestinal tract, including ulcerative colitis, or open ulcerative, traumatic, or surgical wounds. Oral anticoagulants may be contraindi- cated in patients with recent or contemplated brain, eye, or spinal cord surgery or prostatec- tomy, and in those undergoing regional or lumbar block anesthesia or continuous tube drainage of the small intestine.

  • Oral Anticoagulants (VKA and DOAC) Guidelines for Prescribing, Monitoring and Management
    Clinical Guidance Oral Anticoagulants (VKA and DOAC) Guidelines for prescribing, monitoring and management Anticoagulants are one of the classes of medicines which frequently cause harm and admission to hospital. Managing the risk associated with anticoagulants was the subject of The National Patient Safety Agency Patient Safety Alert number 18 March 2007. High risks identified with prescribing anticoagulation include: • Failure to initiate oral anticoagulant therapy where indicated • Poor documentation of reason and treatment plan at commencement of therapy • Incorrect prescribing of oral anticoagulant doses (especially loading doses) The formulary has 5 different anticoagulants to choose from. For the majority of patients, the choice of anticoagulant is guided by indication, clinician and patient choice after appropriate discussion of risks and benefits of the different options. Anticoagulation is not advisable if the risk of harm is likely to outweigh the benefits of treatment. Consideration should be given to the safety of initiating oral anticoagulants in patients with: • cognitive impairment • risk of falls/ with a history of falls, • history of bleeding, • excess alcohol intake • liver disease • impaired visual acuity The HASBLED score can be used to give an indication of the overall risk of bleeding. This scoring system has been validated in patients with atrial fibrillation (it is not validated in the VTE setting). Clinical characteristic Points awarded H Hypertension 1 A Abnormal renal and liver function (1 point each) 1 or 2 S Stroke 1 B Bleeding 1 L Labile INRs 1 E Elderly (age >65 years) 1 D Drugs or alcohol (1 point each) 1 or 2 Maximum 9 points A score of 3 or more indicates increased one year bleed risk on anticoagulation sufficient to justify caution or more regular review.

  • Warfarin, Acenocoumarol, Phenindione
    797FM.3.1 ORAL ANTICOAGULANTS – WARFARIN, ACENOCOUMAROL AND PHENINDIONE, WHEN DOSES ARE ADJUSTED BY THE ANTICOAGULATION CLINIC AND PRESCRIBED BY THE GENERAL PRACTITIONER Shared Care Protocol This protocol provides prescribing and monitoring guidance for oral anticoagulant therapy with warfarin, acenocoumarol or phenindione. It should be read in conjunction with the shared care responsibilities, the Summary of Product Characteristics (SPC) available on www.medicines.org.uk/emc and the BNF. BACKGROUND FOR USE This agreement outlines the ways in which the responsibilities for prescribing of oral anticoagulation with warfarin, acenocoumarol or phenindione are shared where the anticoagulation monitoring service recommends doses and the general practitioner (GP) prescribes them. Sharing of care assumes communication between the anticoagulant monitoring service, GP and patient. The intention to share care should be explained to the patient by both the patient’s GP and the healthcare professional initiating treatment. It is important that patients are consulted about treatment and are in agreement with it. Patients treated with oral anticoagulants are under regular follow-up, which provides an opportunity to discuss drug therapy. It is the responsibility of both the anticoagulation monitoring service and the GP to maintain competencies relevant to their roles. The anticoagulation monitoring service is responsible for ongoing audit of the quality assurance components of the service. The doctor who prescribes the medication legally assumes clinical responsibility for the drug and the consequences of its use. SUPPORTING INFORMATION The vitamin K antagonist (VKA) oral anticoagulant of choice is warfarin. A small number of patients are intolerant of warfarin and many of these are able to switch to direct oral anticoagulant (DOAC) drugs.

Note: Warfarin is by far the most commonly used oral anticoagulant. However, the use of direct oral anticoagulants (eg, rivaroxaban) is gradually increasing. These directly act on clotting factors and do not require routine monitoring of INR value.
