  • West Essex CCG Anticholinergic Side-Effects and Prescribing Guidance
    Anticholinergic side-effects and prescribing guidance . Anticholinergic (antimuscarinic) medications: associated with increased risks of impaired cognition and falls in patients over the age of 65 years. Recent research also points to a link to mortality increasing with the number and potency of anticholinergic agents prescribed. Anticholinergic Syndrome: is a state of confusion with characteristic features related to dysfunction of the autonomic parasympathetic (cholinergic) nervous system. Symptoms classified into systemic and CNS manifestations: o Systemic (peripheral) symptoms: Blurred vision, photophobia, non-reactive mydriasis, loss of accommodation response, flushed and dry skin, dry mouth, tachycardia, hypertension and fever. Gastrointestinal and urinary motility are frequently reduced o CNS symptoms: Delirium, agitation, disorientation, and visual hallucinations. Ataxia, choreoathetosis, myoclonus and seizures may also occur without peripheral symptoms. Medication Issues: several commonly prescribed medications that may not be thought of as anticholinergic have significant anticholinergic effects, which when taken with known anticholinergic medication can increase the risk of adverse effects. Many medication groups e.g. antihistamines, tricyclic antidepressants, drugs for asthma and COPD, cold preparations, hyoscine have varying degrees of anticholinergic activity and have the potential to cause Anticholinergic Syndrome . Clinicians should be aware of the risk for chronic anticholinergic toxicity and the fact that not all the symptoms may manifest in patients and if they do suffer some symptoms they could be wrongly attributed to another diagnosis Evidence . A study of patients over 65 found that 20% of participants who scored four or more had died by the end of the two year study period compared with 7% of patients with a score of zero.

    3rd Edition, 2018 If using any content from this document, please acknowledge the Scottish Government Polypharmacy Model of Care Group, 2018. When referencing this document, please use the following format: Scottish Government Polypharmacy Model of Care Group. Polypharmacy Guidance, Realistic Prescribing 3rd Edition, 2018. Scottish Government Cover images courtesy of jk1991 at FreeDigitalPhotos.net Infographics courtesy of SIMPATHY consortium Key words and search terms: polypharmacy, appropriate polypharmacy, inappropriate polypharmacy, deprescribing, 7-Steps, Drug Efficacy (NNT), Anticholinergic Burden, Cumulative Toxicity, Polypharmacy Indicators, Case Finding Indicators, Outcomes Indicators 2 3 Foreword The care of patients with multi-morbidities (multiple medical conditions) is the greatest challenge now faced by the health service, as it can create overly complex health care for some of the most vulnerable in society. The vast majority of medical research, guidelines and contractual agreements have focussed on single targets for single disease states, whereas in reality most patients have multi-morbidities, requiring multiple treatments.1 The resulting polypharmacy (use of multiple medicines) can be appropriate or inappropriate and the key healthcare aim for the individual patient is to ensure the safe and effective use of their multiple medicines. Despite research into this area being in relative infancy there exists a requirement to produce guidance for both patients and healthcare providers, based on the best evidence to date. Polypharmacy becomes inappropriate when the medication risks begin to outweigh benefits for an individual patient. The aim of addressing this is to identify those patients at greatest risk of harm and to agree a medication regimen that is tailored to their changing needs and expectations.

  • Myasthenia Gravis Or Lambert-Eaton Myasthenia Syndrome – Medicines That May Affect Patients
    CLINICAL GUIDELINE Myasthenia Gravis or Lambert-Eaton Myasthenia Syndrome – Medicines that may affect patients A guideline is intended to assist healthcare professionals in the choice of disease-specific treatments. Clinical judgement should be exercised on the applicability of any guideline, influenced by individual patient characteristics. Clinicians should be mindful of the potential for harmful polypharmacy and increased susceptibility to adverse drug reactions in patients with multiple morbidities or frailty. If, after discussion with the patient or carer, there are good reasons for not following a guideline, it is good practice to record these and communicate them to others involved in the care of the patient. Version Number: 1 Does this version include n/a changes to clinical advice: Date Approved: 11th July 2018 Date of Next Review: 30th July 2021 Lead Author: Lesley Murray Approval Group: Medicines Utilisation Subcommittee of ADTC Important Note: The Intranet version of this document is the only version that is maintained. Any printed copies should therefore be viewed as ‘Uncontrolled’ and as such, may not necessarily contain the latest updates and amendments. Information for healthcare professionals Medicines that may affect patients with Myasthenia Gravis or Lambert-Eaton Myasthenic Syndrome There are certain medicines that have been reported to worsen or induce myasthenia gravis (MG), often by increasing muscular weakness, and should be used with caution in patients with this condition. The list of medicines in table 1 has been compiled to assist prescribers in the decision making process when prescribing medicines for patients with myasthenia gravis. The medicines in this list have been classed according to those which should be: ▲ ▲Absolutely contraindicated ▲ Avoided Used with caution Probably safe with patient monitoring.
