Issue 13, March 2015 Wirral Drug & Therapeutics Committee UPDATE……………………………………………………………………………………………………………………..1 Current Issues............................................................................................................................................................................. 1 Topic of the month ..................................................................................................................................................................... 2 Drug Tariff .................................................................................................................................................................................. 4 Safety ......................................................................................................................................................................................... 7 Wirral Drug & Therapeutics Committee UPDATE Alogliptin tablets (Vipidia®▼) Alogliptin has been approved by the Drug & Therapeutics Committee (D&T) (January 2015) as the first line gliptin to use for type 2 diabetic patients requiring gliptin therapy as per the Type 2 Diabetes Guidelines. http://mm.wirral.nhs.uk/guidelines/ Once the black triangle status of alogliptin has been removed, a switch to alogliptin will be considered for patients on other gliptins. NOAC RAG Status Clarification Following a review of the RAG status of NOACs at January D&T the following indications have these agreed RAG statuses (within their NICE TAGs): Indication RAG status For treatment of DVT and/or PE AMBER For prevention of recurrent DVT and/or PE Anticoagulation in AF GREEN VTE prophylaxis post hip and knee surgery RED Current Issues Supply of LMWH on discharge for VTE prophylaxis in orthopaedic patients Joint Wirral Anticoagulant Guidelines currently state that up to 2 weeks’ supply of LMWH will be made by the hospital at discharge for VTE prophylaxis in orthopaedic patients, and then this should be continued by the patient’s GP. However, this has never been carried out in practice for orthopaedic patients that have undergone a fracture and are in a cast, who may or may not have needed surgery, and WUTH have continued to supply up to 4 weeks of enoxaparin on discharge. 1 From the beginning of March, WUTH will now be supplying 2 weeks of enoxaparin for these orthopaedic patients, in line with the Joint Guidelines and the remainder of the course should be prescribed by the GP. Further guidance on the prescribing and monitoring of LMWH can be found in the links below. Joint Wirral Anticoagulant Guidelines http://mm.wirral.nhs.uk/document_uploads/guidelines/LMWHprescribingandadministrationclinicalguidelinev1a141 013.pdf Venothromboembolism prophylaxis: Trauma and Orthopaedics Guidelines http://mm.wirral.nhs.uk/document_uploads/guidelines/VTEprophylaxisTraumaandorthopaedicsv2.pdf The new naming system for NICE guidelines - say hello to NG NICE has started to use a new way of numbering guidelines following the decision to use a single set of methods and processes to develop all NICE guidelines. This applies to clinical, public health, social care, safe staffing and medicines practice guidelines. In January 2015, NICE published the first clinical guideline with the new numbering system, NG1 GORD in children and young people. Please note that other guidance products, i.e. technology appraisals, interventional procedures, medical technologies and diagnostics guidance, as well as quality standards and advice products, will be unaffected by this change. Topic of the month UNLICENSED MEDICATION – ‘SPECIALS’ Wirral CCG spent £268,082.77 on special-order medicines in the period April to November 20141. Special-order products, also known as ‘Specials’, are unlicensed, premium-priced medicines. Reviewing and preventing inappropriate use of unlicensed medicines is a regular piece of work for the Medicines Management Team. The cost of unlicensed medicines can vary widely depending on where it is sourced by the Community Pharmacy. The introduction of the Specials Tariff in Part VIIIB of the Drug Tariff has helped to reduce this variance in cost for some products, but care needs to be taken when choosing between formulations, as shown in the table below: Specials in Part VIIIB Cost2 for Comments 150ml Lorazepam oral solution 500mcg/5ml Lorazepam oral suspension 500mcg/5ml Zopiclone oral suspension 3.75mg/5ml Zopiclone oral solution 3.75mg/5ml £47.54 £98.17 £116.31 £40.01 Prescribing as solution is more cost effective, although tablets can be crushed and mixed with water or will disperse in water in 1-5 minutes. Prescribing as solution is more cost effective. Another option would be to consider changing to zolpidem tablets which can be crushed and mixed with water. 2 .Where the medicine is not listed in Part VIIIB of the Drug Tariff, the price depends on where the Dispenser sources the product, and the Prescriber usually has no influence on this, as shown below: Cost3 Comments Midodrine 5mg tablets £36.90/100 tablets from Dispenser A £58.49/100 tablets from Dispenser B This is a RED drug so should not be issued in Primary Care Phytomenadione 10mg tablets £110.52/30 tablets from Dispenser A £64.34/30 tablets from Dispenser B £459 for 250g This is an AMBER drug but price depends on the supplier Unlicensed specials not in Part VIIIB 50% diprosone ointment 0.05% with 50% diprobase ointment Patients should be reviewed to see if the ointment is still clinically indicated and if a licensed alternative could be prescribed as an alternative. As with any medicine, prescribers take full responsibility for their prescribing decision including any risks associated with the use of unlicensed medicines. Another important consideration for prescribers is that specials have not been assessed by the Medicine and Healthcare products Regulatory Agency (MHRA) for safety, quality and efficacy in the same way as licensed medicines. Therefore, they have no Summary of Product Characteristics (SPC) outlining the dose, contraindications, storage and side-effect profile. The MHRA recommends that an unlicensed medicinal product should not be supplied where an equivalent licensed medicinal product can meet the “special needs” of the patient.4 Advice to Prescribers Prescribers should establish a ‘special clinical need’ before initiating or continuing a prescription for a ’special’. A medication review prior to considering a ‘special’ may help to identify medicines which are no longer needed or unsuitable for continuation. If there is still a clinical need for the medicine, the following options could be considered instead of unlicensed ‘specials’: Another licensed product in the same therapeutic class may be available in a suitable formulation for the patient. A different formulation of a licensed medicine may be available such as dispersible tablets, suppositories or patches. Using a UK licensed medicine outside the terms of its licence, e.g. outside defined indications, doses, routes of administration. This is referred to as ‘off-label’ use, e.g. crushing tablets or opening capsules (where the formulation allows). The NEWT Guidelines is a good source for advice. Although the MHRA does not recommend ’off label’ use of products, if the UK licensed product can meet the clinical need, even ‘off-label’, it should be used instead of an unlicensed product. It should be understood that the prescriber’s responsibility and potential liability are increased when prescribing ‘off-label’.4 If the UK licensed product cannot meet the special need, then another (imported) medicinal product should be considered, which is licensed in the country of origin.4 3 If there is no licensed alternative that meets the patient’s clinical need, then an unlicensed UK manufactured ‘special’ can be considered.4 Where an unlicensed ‘special’ is prescribed then prescribers are advised to follow relevant professional guidance, taking full responsibility for the decision. The patient (or those with authority to give consent on their behalf) should provide informed consent, which should be documented in the patient notes. The need for a ‘special’ should be reviewed regularly, as well as the need for the drug itself. References: 1. ePACT. Medicines Management Financial Management Report. November 2014. 2.

NHSBSA Prescription Services has identified an increase in FP34P/D Appendix forms and FP10 forms claiming payment for Fluenz Tetra®▼ nasal spray suspension Influenza vaccine, NeisVac-C® vaccine and Boostrix IPV® injection where practices have later verified these have been centrally procured via a vaccine ordering facility, such as ImmForm. Practices must not submit payment claims for vaccines or injections obtained in this way to the NHSBSA. An FP34P/D appendix or FP10 form should only be submitted for payment to cover the ‘dispensing’ of the vaccine for personal administration where the vaccine has been purchased by the practice. Practices who have incorrectly submitted centrally procured vaccines to NHSBSA Prescription Services should contact [email protected] for a payment adjustment.

Safety Medicines Optimisation: Identifying medicines associated with serious medication errors. A recent article ‘Identifying high-risk medication: a systematic literature review’, published in the European Journal of Clinical Pharmacology http://www.ncbi.nlm.nih.gov/pubmed/24671697 identified those drugs reported to most commonly cause serious adverse reactions because of medication errors.

Although this death remains under investigation, it appears the powder formed a solid mass which caused fatal airway obstruction. Whilst it is important that products remain accessible, all relevant staff need to be aware of potential risks to patient safety. Appropriate storage and administration of thickening powder needs to be embedded within the wider context of protocols, bedside documentation and training programmes, and access to expert advice is required to safely manage all aspects of the care of individuals with dysphagia. Individualised risk assessment and care planning is required to ensure that vulnerable people are identified and protected. For further information please go to: http://www.england.nhs.uk/2015/02/06/psa-fluidfood-thickening-powder/ Unintentional overdose more likely with long-acting opioids Results from a US cohort study published in the JAMA Internal Medicine suggest that long-acting opioids carry a higher risk of unintentional overdose than short-acting formulations. Patients starting long-acting opioids to manage chronic pain were more than twice as likely to overdose compared to starting treatment with short-acting opioids with the highest risk being within the first two weeks of initiating treatment. The study suggests that clinicians weighing the benefits and risks of initiating different opioid regimens should consider not only the daily dose prescribed but also the duration of opioid action. Common antibiotic taken with a diuretic linked to sudden death in older patients Spironolactone, a diuretic used in heart failure, has been linked to sudden death when taken with co-trimoxazole, a recent Canadian study has found. It is well documented that spironolactone cause hyperkalaemia but so can trimethoprim. A retrospective study in 2011 demonstrated the risk of hospital admission resulting from hyperkalaemia in elderly patients taking spironolactone alongside trimethoprim–sulfamethoxazole (co-trimoxazole). This study used the administrative health records, spanning 18 years, of more than 200,000 patients prescribed spironolactone. The 2011 study did not establish whether the drug interaction was associated with an increased risk of death but more recent analysis of the same data found that of the 11,968 patients who died of sudden death while receiving potassium-elevating spironolactone, 328 died within 14 days of exposure to certain antibiotics: co-trimoxazole, amoxicillin, ciprofloxacin, norfloxacin or nitrofurantoin. Most of the patients receiving spironolactone treatment who died suddenly were 85 years of age or older. The risk of sudden death was twice as likely with co-trimoxazole compared to those taking amoxicillin. Hyperkalaemia is a common adverse effect of spironolactone and so the additive adverse effects should be expected from any drug known to cause hyperkalaemia. 8 Hydroxyzine – new measures to minimise cardiac risks The EMA’s Pharmacovigilance Risk Assessment Committee (PRAC) has confirmed that hydroxyzine is associated with a ‘small but definite’ risk of prolonged QT and torsade de pointes. PRAC has stated that hydroxyzine-containing medicines can still be used but new recommendations should be followed to minimise risk. These recommendations include: Use the medicine at the lowest effective dose for as short a time as possible Use is not recommended in the elderly The maximum daily dose should be no more than 100 mg in adults (50 mg in the elderly if use cannot be avoided), and 2 mg per kg body weight where used in children up to 40 kg in weight Use must be avoided in patients who already have risk factors for heart rhythm disturbances or are taking other medicines that increase the risk of QT prolongation Care is also needed in patients taking medicines that slow the heart rate or decrease the level of potassium in the blood, as these also increase the risk of problems with heart rhythm. PRAC confirmed the known possibility of QT interval prolongation and torsade de pointes with hydroxyzine, and noted that such events were most likely to occur in patients who had risk factors. The risk can therefore be decreased by restricting hydroxyzine use in those most at risk of heart rhythm problems and reducing exposure to the medicine. The PRAC recommendations will now be considered and a final position will be prepared; guidance for patients and healthcare professionals will then follow.
