Reduced Shared Care Protocol –remains open to review in light of any new evidence Amber with guidance (Amber-G) = To be initiated and titrated to a stable dose by a specialist prescriber with follow up prescribing by primary care Ivabradine(Procoloran®) Reduced Shared Care Guideline for the use of ivabradine for the symptomatic treatment of chronic stable angina pectoris. This Guideline was originally produced in 2007 By Chris Lawson following consultation with specialists at Barnsley Hospital. The Guideline has been updated by Caron Applebee (Prescribing Support Pharmacist) with input from Gillian Smith (Medicines Information Pharmacist BHNFT) and the Cardiologists (Dr Tahir, Dr Etorki and Dr Yousaf). This guideline has been subject to consultation and endorsement by: The Area Prescribing Committee on 14th November 2012. The LMC on 11th December 2012. Introduction Indication/Licensing information Ivabradine is licensed for the symptomatic treatment of chronic stable angina pectoris in patients with normal sinus rhythm, who have a contra-indication or intolerance to beta-blockers. Pharmacology Ivabradine blocks a specific ion channel, the (If) or funny channel which is found in sino-atrial node cells which results in a reduction in resting heart rate. Dosage and administration Starting dose; 5mg twice daily. After three to four weeks of treatment the dose may be increased to 7.5mg twice daily depending on therapeutic response. If heart rate decreases persistently below 50 beats per minute (bpm) at rest or the patient experiences symptoms related to bradycardia such as dizziness, fatigue or hypotension, the dose must be titrated downward including the possible dose of 2.5 mg twice daily (one half 5 mg tablet twice daily). Treatment must be discontinued if heart rate falls below 50 bpm or symptoms of bradycardia persists (see section 4.4 of the SPC http://emc.medicines.org.uk/). Elderly:Patients over 75yrs should commence on 2.5mg twice daily. Dose reduction or cessation should be considered if the heart rate drops below 50bpm.

To discuss the benefits and side effects of treatment with the patient/carer and the need for long term monitoring if applicable. To perform baseline tests and if appropriate routine tests until the patient is stable. To prescribe until the patient is stabilised on ivabradine (minimum of 4 weeks). To explain shared care to the patient and gain acceptance from them To ask the GP whether they are willing to participate in shared care. To provide the GP with a summary of information relating to the individual patient to support the GP in undertaking shared care (See Shared care request form in Appendix A). To advise the GP of any dosage adjustments required, monitoring required, when to refer back, and when and how to stop treatment (if appropriate). To advise the GP when the patient will next be reviewed by the specialist. To monitor the patient for adverse events and report to the GP and where appropriate Commission on Human Medicines/MHRA (Yellow card scheme). To provide the GP with contact details in case of queries. To review the patient if indicated or requested by the GP. T o inform the GP if patient misses repeated follow up appointments. Baseline Tests Resting heart rate. Routine Tests Resting heart rate. If heart rate decreases persistently below 50 beats per minute (bpm) at rest or the patient experiences symptoms related to bradycardia such as dizziness, fatigue or hypotension, the dose must be titrated downward including the possible dose of 2.5 mg twice daily (one half 5 mg tablet twice daily). Treatment must be discontinued if heart rate falls below 50 bpm or symptoms of bradycardia persists Disease monitoring The patient will be reviewed in Secondary Care within 3 months of discharge from hospital then every 4-6 months until the patient is stable. Responsibilities of other prescribers Acceptance of Responsibility by the Primary Care Clinician It is optional for GPs to participate in taking on responsibility for reduced shared care for the patient. GPs will take on shared care only if they are willing and able. Summary To reply to the request for reduced shared care as soon as possible. To prescribe and adjust the dose as recommended by the specialist. To ensure there are no interactions with any other medications initiated in primary care. To continue monitoring as agreed with secondary care (guideline should include details of monitoring requirements and what to do when each of the defined parameters alters). To refer back to the specialist where appropriate. For example: o Patient or general practitioner is not comfortable to continue with the existing regime due to either change in condition or drug side effects. o Advice in respect of concordance. o Special situations, (e.g. Pregnancy) Discontinue the drug as directed by the specialist if required or immediately should the patient’s condition seriously deteriorate (e.g. severe hypotension, cardiogenic shock, symptomatic bradycardia) To identify adverse events if the patient presents with any signs and liaise with the hospital specialist where necessary. To report adverse events to the specialist and where appropriate the Commission on Human Medicines/MHRA (Yellow card scheme).
