Promising Results Published
The outcomes, published this month in The Lancet, showed that clients taking amitriptyline were practically twice as most likely to report a total improvement in signs as those taking a placebo.
Now the trial team is recommending that GPs support their patients with IBS to utilize amitriptyline to manage their symptoms– and has actually made the dose modification document readily available for clinicians and patients.
Expert Insights
Co-chief Investigator Alexander Ford, Professor of Gastroenterology in the University of Leedss School of Medicine, stated: “Amitriptyline is a reliable treatment for IBS and is safe and well endured. This brand-new rigorously conducted research suggests that family doctors should support patients in medical care to attempt low-dose amitriptyline if their IBS symptoms havent improved with advised first-line treatments.”
About IBS and Amitriptyline
IBS, which affects around 1 in 20 people worldwide, triggers abdominal discomfort and changes to bowel motions. The long-lasting condition, which has no recognized cure, fluctuates in seriousness in time. It can have a considerable effect on lifestyle and capability to work and mingle. Many treatments just have a modest impact and individuals typically have continuous frustrating symptoms.
Amitriptyline comes from a group of medications called tricyclics. Originally used at high doses to deal with depression, today these are hardly ever used for this condition because newer treatments have been established.
Previous small trials of low-dose tricyclic antidepressants for IBS recommended a possible benefit in patients seen in medical facility clinics, who typically have more difficult-to-treat symptoms, but this brand-new research study is the first randomised regulated trial of low-dose amitriptyline versus a placebo tablet for IBS in main care. It is likewise the biggest trial of amitriptyline for IBS undertaken worldwide.
Supporting Evidence and Recommendations
GPs currently prescribe low-dose amitriptyline to deal with persistent nerve and pain in the back, and to help avoid migraine attacks. Great guidelines presently specify that GPs could consider utilizing a low dosage tricyclic, like amitriptyline, for IBS however, until now, the evidence for a benefit has doubted.
Based on the results of the trial, which showed a clear advantage of amitriptyline, GPs can use low-dose amitriptyline to individuals with IBS as part of shared decision making if symptoms do not enhance with first-line treatments.
Co-chief Investigator Hazel Everitt, Professor of Primary Care Research at the Primary Care Research Centre, University of Southampton, said: “Prior to ATLANTIS, GPs have not typically recommended amitriptyline for IBS as the research study proof was unpredictable, but our new research study provides excellent proof of advantage.
” GPs currently recommend low-dose amitriptyline for other conditions, such as chronic pain and poor sleep, and when we spoke with GPs as part of this research study, they were prepared to prescribe it for IBS if the research study proof supported this. Participants were also keen to have another option to attempt to help their IBS signs and the majority of were happy to self-adjust their dosage depending upon symptoms and side impacts.”.
Findings and participants.
The ATLANTIS trial was moneyed by the NIHR Heath Technology Assessment program. Some 463 people with IBS took part from three areas throughout the UK– West Yorkshire, Wessex, and West of England. They were hired from 55 basic practices.
Participants were put at random into two groups– those receiving amitriptyline and those receiving a placebo. Individuals managed the number of tablets of the trial medication they took, receiving support by means of the client dose modification file that was established with client agents particularly for this trial. This allowed individuals to increase or decrease the number of tablets based upon their IBS symptoms and any side effects experienced.
Individuals taking amitriptyline reported a larger improvement in their sign scores after six months compared with those taking a placebo. Those taking amitriptyline were almost twice as most likely as those taking a placebo to report a general improvement in IBS signs, with amitriptyline performing much better across a wide variety of IBS symptom steps.
Researchers monitored participants anxiety or depression scores and discovered that they were not altered– recommending that the beneficial effects of the medication were via the gut, not since of any result as an antidepressant.
No security concerns were recognized and adverse effects in people on amitriptyline were mostly mild, such as a dry mouth in the early morning.
Professional Opinions and Further Information.
Matthew Ridd, GP and Professor of Primary Health Care at the Centre for Academic Primary Care, University of Bristol, said: “Pragmatic trials like this are constantly challenging to do in main care and the group strove to conquer the additional challenges of the Covid-19 pandemic. Its great that weve found that amitriptyline is a safe and effective alternative for clients with IBS to try.”.
Amanda Farrin, Professor of Clinical Trials and Evaluation of Complex Interventions, who leads the Complex Intervention Division of the Leeds Clinical Trials Research Unit, said: “The individuals in the ATLANTIS trial had moderate to serious symptoms and a typical period of IBS of 10 years. The truth that amitriptyline had such a big impact over a placebo is substantial because it can assist enhance the lifestyle of clients with this condition.”.
Conclusion.
Professor Andrew Farmer, Director NIHRs Health Technology Assessment (HTA) Programme, stated: “The outcomes of this research study are extremely motivating. It shows that a drug currently widely offered to deal with a variety of other conditions seems efficient and safe for individuals with IBS. The findings the research study group has shared around the change of does can be enormously helpful to GPs in guiding them when dealing with clients.
” IBS impacts a substantial number of individuals in the UK and can have an incapacitating impact on their daily lives. This is another outstanding example of how premium research study can lead to favorable changes in health and social care practice and treatments for the benefit of patients and health care specialists.”.

IBS ratings were determined using the IBS-SSS scale. Amitriptyline participants scored a 99-point improvement compared with a 69-point improvement amongst placebo participants.

Research from the ATLANTIS trial presented at UEG Week 2023 shows that the typical drug amitriptyline can substantially minimize irritable bowel syndrome (IBS) symptoms, offering a brand-new treatment opportunity for clients.
A widely offered and inexpensive prescription drug can enhance signs of irritable bowel syndrome in clients seen in GP surgeries, brand-new research study has actually discovered. The study was recently presented at UEG Week 2023, a conference by the European Society of Gastrointestinal Endoscopy.
The ATLANTIS Trial
Amitriptyline, which is commonly utilized at low doses for a variety of health issues, has actually been discovered to enhance irritable bowel syndrome (IBS) symptoms too, according to the results of the ATLANTIS trial.
Led by scientists at the Universities of Leeds, Southampton, and Bristol and funded by the National Institute for Health and Care Research (NIHR), the study was carried out in main care. GPs prescribed the drug and patients managed their own dosage based upon the severity of their signs, using an adjustment document created for the trial. Most individuals with IBS are seen and managed in medical care by their GP, which indicates that the results of this trial are most likely to be applicable to numerous individuals with the condition.
GPs prescribed the drug and patients managed their own dosage based on the seriousness of their signs, utilizing a change document designed for the trial. Many individuals with IBS are seen and managed in primary care by their GP, which indicates that the outcomes of this trial are likely to be appropriate to many people with the condition.
The majority of treatments only have a modest effect and people frequently have continuous troublesome signs.
Participants were put at random into two groups– those receiving amitriptyline and those getting a placebo. Individuals controlled how numerous tablets of the trial medication they took, getting support by means of the client dose change document that was established with client representatives specifically for this trial.
