These changes include contraindications to concomitant use with certain medicines and maximum dose recommendations when simvastatin is taken with a number of other medicines, as these interactions may increase plasma concentrations of simvastatin which is associated with an increased risk of myopathy and / or rhabdomyolysis. Key changes Simvastatin is now contraindicated with ciclosporin, danazol and gemfibrozil The maximum recommended dose for simvastatin in conjunction with amiodarone, amlodipine, diltiazem or verapamil is now 20mg/day Recommendations Patients currently prescribed simvastatin 40mg and amiodarone, amlodipine, diltiazem or verapamil Secondary Prevention Switch to atorvastatin 10mg daily, increasing to atorvastatin 20mg daily if required to achieve target lipid levels Atorvastatin has also been reported to interact with amiodarone, amlodipine, diltiazem and verapamil to increase the atorvastatin level but to a lesser extent than simvastatin. Primary Prevention Switch to pravastatin 40mg daily Pravastatin does not interact with amiodarone, amlodipine, diltiazem or verapamil. Prescribers are asked NOT to switch patients from simvastatin to rosuvastatin unless there is no clinically acceptable alternative due to cost implications (atorvastatin 20mg £2.18, pravastatin 40mg £2.37, simvastatin 20mg £0.73, atorvastatin 10mg £1.55, rosuvastatin 10mg £18.03 for 28 days treatment). Prescribers are NOT advised to switch to an alternative calcium channel blocker as this is clinically less desirable especially where patients are well controlled on their current calcium channel blocker. Patients currently prescribed simvastatin and ciclosporin, danazol or gemfibrozil Stop the simvastatin and switch to an alternative statin. Recommended alternative statins are: • With ciclosporin: EITHER Atorvastatin at a maximum dose of 10mg (higher atorvastatin doses are contraindicated with ciclosporin); OR pravastatin 20mg daily increasing to 40mg daily if required with careful monitoring • With danazol: EITHER Atorvastatin initiated at 10mg daily, increasing as required to control lipids, with careful monitoring; OR pravastatin up to 40mg daily. Danazol is known to interact with artovastatin but to a lesser extent than simvastatin • With gemfibrozil: All statins interact with gemfibrozil. The combined use of gemfibrozil with a statin should generally be avoided. Review all patients prescribed gemfibrozil and any statin. If the benefit of this combination is still considered to outweigh the risk use EITHER Atorvastatin initiated at 10mg daily, increasing as required to control lipids, with careful monitoring; OR pravastatin up to 40mg daily The full recommendations are located on the NHS Eastern and Coastal Kent website: http://www.easternandcoastalkent.nhs.uk/home/independent-contractors/medicines-management/drugformulary-and-prescribing-policies/cardiovascular-system/ BENZODIAZEPINE USE AND RISK OF DEMENTIA The BMJ has reported a prospective, population based study which evaluated the association between the use of benzodiazepines and incident dementia (PAQUID study, France). The study participants were 1063 men and women (mean age 78.2 years) who were free of dementia and did not start taking benzodiazepines until at least the third year of follow-up. The main outcome measure was incident dementia, confirmed by a neurologist. During a 15 year follow-up, 253 incident cases of dementia were confirmed. New use of benzodiazepines was associated with an increased risk of dementia (multivariable adjusted hazard ratio 1.60, 95% confidence interval 1.08 to 2.38). Sensitivity analysis considering the existence of depressive symptoms showed a similar association (hazard ratio 1.62, 1.08 to 2.43). A secondary analysis pooled cohorts of participants who started benzodiazepines during follow-up and evaluated the association with incident dementia. The pooled hazard ratio across the five cohorts of new benzodiazepine users was 1.46 (1.10 to 1.94). Results of a complementary nested case-control study showed that ever use of benzodiazepines was associated with an approximately 50% increase in the risk of dementia (adjusted odds ratio 1.55, 1.24 to 1.95) compared with never users. The results were similar in past users (odds ratio 1.56, 1.23 to 1.98) and recent users (1.48, 0.83 to 2.63) but reached significance only for past users. The authors concluded “In this prospective population based study, new use of benzodiazepines was associated with increased risk of dementia. The result was robust in pooled analyses across cohorts of new users of benzodiazepines throughout the study and in a complementary case-control study. Considering the extent to which benzodiazepines are prescribed and the number of potential adverse effects of this drug class in the general population, indiscriminate widespread use should be cautioned against.” http://www.bmj.com/content/345/bmj.e6231 UPPER GASTROINTESTINAL BLEEDING – RE-PRESCRIBING OF ASSOCIATED DRUGS A study has found that, in the year after being discharged from hospital following a drug-related upper gastrointestinal bleed, between 25% (for NSAIDs) and 82% (for SSRIs) of people redeemed a prescription for the drug that was associated with that bleed. Proton pump inhibitors were generally, but by no means always, co-prescribed. Prescribers are advised to follow NICE guidance on the prevention of re-bleeding in patients on NSAIDs, aspirin or clopidogrel and also take note of advice in the BNF on the risks of gastrointestinal bleeds with SSRIS and other drugs. http://www.ncbi.nlm.nih.gov/pubmed/22313346 PERTUSSIS (WHOOPING COUGH) VACCINATION FOR PREGNANT WOMEN Following a sharp rise in cases of whooping cough with nine babies having died from the disease up to the end of August the Chief Medical Officer has announced a programme of vaccination for expectant mothers in weeks 28 to 38 of their pregnancy. The Joint Committee on Vaccination and Immunisation (JCVI) has agreed that women in week 28 of their pregnancy up to week 38 should be vaccinated with the whooping cough (pertussis) vaccine, as this is the only way to protect their babies from birth from infection until they can be vaccinated at two months of age. News item: http://www.dh.gov.uk/health/2012/09/whooping-cough/ Further information: http://www.dh.gov.uk/health/2012/09/whooping-cough-information/ Resources: http://www.dh.gov.uk/health/2012/09/whooping-cough-resources/ DEPARTMENT OF HEALTH WARNS OF MISUSE OF METHADONE IN CHILDREN The Department of Health has received notification that some parents / carers have illicitly given part of their prescribed methadone to their child(ren), to help treat an illness and / or to help aid their sleep, sometimes with tragic consequences. The Department highlights to clinicians that when advising patients about the risks of methadone to children, such as fatal overdose, and the importance of safe use and storage, to consider reinforcing the message that even a small amount of methadone could have fatal consequences if consumed by a child. http://www.dh.gov.uk/health/2012/09/the-week-issue-265-14-20-september-2012/ http://www.nta.nhs.uk/uploads/clinical_guidelines_2007.pdf EUROPEAN ANTIBIOTIC AWARENESS DAY European Antibiotic Awareness Day (EAAD), which takes place on 18 November 2012, raises public and professional awareness of the need for responsible prescribing to slow down the development of antibiotic resistance and is part of a national programme to combat antimicrobial resistance. Antibiotic resistance is driven by the over-use of antibiotics and inappropriate prescribing of antibiotics. The number of infections due to antibiotic-resistant bacteria is growing and there is a lack of new antibiotics. Activities will be launched from Friday 16th November. Materials have been produced centrally to prevent duplication of effort and ensure consistency of message. The Department of Health is providing a range of educational materials to help implement local campaigns and initiatives. These can be downloaded from the DoH website at http://www.dh.gov.uk/health/tag/eaad/ and a limited number of hardcopy posters and leaflets are available. http://www.dh.gov.uk/health/2012/10/eaad-resources/ HPA TRAVEL ADVICE FOR HAJJ PILGRIMS Around 25,000 people are expected to travel from the UK to Saudi Arabia for this year's Hajj, which is taking place from 24-29 October. A large population from around the world confined to one area has historically increased the risk of infectious disease outbreaks, in particular meningitis and respiratory infections. The Health Protection Agency (HPA) and the National Travel Health Network and Centre (NaTHNaC) want to remind people to seek health advice before making the journey to ensure a healthy trip. http://www.hpa.org.uk/NewsCentre/NationalPressReleases/2012PressReleases/121003TraveladviceforHajj pilgrims/ PRODUCT UPDATES Tamiflu Suspension - Change in Product Strength Roche Products Limited has advised on new concentration and dosing instructions of Tamiflu® oral suspension (oseltamivir phosphate). The main points are: Concentration of TAMIFLU® for Oral Suspension will be changed from 12 mg/ml to 6 mg/ml The dispenser will be changed from milligrams (mgs) to millilitres (mLs) The EU SPCs will be changed to include amended dosing tables to include a column for the volume in millilitres based on the new 6 mg/ml formulation. Prescriptions for Tamiflu® oral suspension should state the dose in millilitres and the new 6mg/ml concentration should be used. Patients and parents / guardians of children should be carefully advised that the carton packaging, dosing dispenser and packaging leaflet of the new oral suspension are different from what they may have used in the past. Tamiflu is indicated for treatment of influenza in patients one year of age and older who present with symptoms typical of influenza, when influenza virus is circulating in the community within two days of first onset of symptoms. It is also indicated for post-exposure prevention in individuals one year of age or older following contact with a clinically diagnosed influenza case when influenza virus is circulating in the community. During a pandemic influenza outbreak Tamiflu is also indicated for the treatment and postexposure prevention of influenza in infants below 12 months of age.

The only thing changing is the name and the box; the tablets will be exactly the same as will the pack sizes and price. Some Mesren is expected to be available until at least March next year. The manufacturer, Tillotts Pharma UK, have produced a number of tools to support prescribers, pharmacist and patients with the changeover process. These are expected to be available shortly. Dovobet (Calcipotriol / Betamethasone Dipropionate) Products From 1st November 2012, Dovobet Ointment 60g will be discontinued. Dovobet Ointment 120g, Dovobet Gel 60g and Dovobet Gel 120g will continue to be available. Slo-drinks A number of care homes have contacted practices after receiving information from the manufacturer of Slodrinks. Slo-drinks are not currently recommended by the Speech and Language Team (SLT) team. Please be reminded that thickeners should be initiated only by the speech and language team. Care homes should not be asking prescribers to initiate thickeners. Prescribers are advised not to accept requests to prescribe thickeners from care homes. Thickeners may not be appropriate for all patients. These patients will require an assessment by SLT to determine appropriate treatment on an individual patient basis. If there is a problem with a patient’s current thickener the SLT team should be contacted to discuss alternatives. The embedded Thickener Reference Sheet contains brief details of thickening agents used by Kent Community Health Trust.

MHRA DRUG SAFETY UPDATE Drug Safety Update September 2012; Volume 6, Issue 2 Paracetamol overdose: new guidance on treatment with intravenous acetylcysteine. New simplified guidance on treating paracetamol overdose with intravenous acetylcysteine is now in place. This includes an updated treatment nomogram. Oseltamivir (Tamiflu): changed concentration and dosing dispenser of oral suspension from October 2012. The strength of oseltamivir (Tamiflu) oral suspension will be 6 mg/mL. A new dosing dispenser, calibrated in mL, will be introduced at the same time. (Please see article above for further information.) Dipeptidylpeptidase-4 inhibitors (‘gliptins’): risk of acute pancreatitis. There have been reports of acute pancreatitis associated with drugs in the dipeptidylpeptidase-4 (DPP-4) inhibitor class of antidiabetic agents (‘gliptins’). Patients should be informed of the characteristic symptoms of acute pancreatitis – persistent, severe abdominal pain (sometimes radiating to the back) – and encouraged to tell their healthcare provider if they have such symptoms. If pancreatitis is suspected, the DPP-4 inhibitor and other potentially suspect medicinal products should be discontinued. Panitumumab (Vectibix): risk of necrotising fasciitis. Severe skin reactions with panitumumab use are known to be very common and may be followed by life-threatening and fatal infectious complications including sepsis and cellulitis. In addition, five cases of necrotising fasciitis, three of which were fatal, have now been reported in patients treated with panitumumab in combination with chemotherapy. Levofloxacin: some indications restricted. Levofloxacin (a fluoroquinolone antibiotic) may only be considered in the treatment of acute bacterial sinusitis, acute exacerbation of chronic bronchitis, community acquired pneumonia or complicated skin and soft tissue infections when other medicines cannot be prescribed, or have been ineffective. http://www.mhra.gov.uk/Safetyinformation/DrugSafetyUpdate/index.htm NICE PUBLICATIONS Technology Appraisals: TA 264 Alteplase for treating acute ischaemic stroke (review of technology appraisal guidance 122).
