GASTROINTESTINAL SYSTEM MANAGEMENT OF DYSPEPSIA MANAGEMENT Dyspepsia refers to a spectrum of usually intermittent upper gastrointestinal symptoms, including epigastric pain and heartburn. For the majority of patients the consequence of dyspepsia is symptoms affecting their quality of life. The impact of this being on the quality of life is a personal experience, a reoccurring problem or a chronic complaint for which the available treatments may be wholly or partially effective to relieve symptoms. Lifestyle changes can help to avoid triggering dyspepsia. Lifestyle advice includes healthy eating, weight reduction and smoking cessation. URGENT REFERRAL Patients who present with alarm symptoms as indicated below should be referred to secondary care: dyspepsia with gastrointestinal bleeding difficulty in swallowing (dysphagia) progressive unintentional weight loss abdominal swelling persistent vomiting persistent weight loss and vomiting or iron deficiency anaemia in the absence of dyspepsia unexplained worsening dyspepsia and Barrett s oesophagus, or peptic ulcer surgery over 20 years ago. Urgent endoscopy for patients aged 55 and over with unexplained and persistent recent-onset dyspepsia alone All patients should have their medication reviewed to check if they are prescribed any medications that may cause dyspepsia such as calcium channel blockers, nitrates, theophyllines, bisphosphonates, corticosteroids and NSAID s. It is also vital that any over-the-counter medicines are reviewed. 1

Specific Indication orodispersible tablets (Zoton FasTab ) This should be reserved for patients with swallowing difficulties or who may require a proton pump inhibitor via nasogastric (NG) or percutaneous endoscopic gastrostomy (PEG) tube. orodispersible tablets (Zoton FasTab ) 30mg daily for 28 days then reduce H. Pylori Eradication First Line for 1 week treatment only Prescribing is reserved for specific indications as detailed above.

Emphasise compliance with treatment, possible success rate of 85%. If patient needs another course of treatment a different regime should be prescribed. Refer to latest BNF section 1.3 for recommended regimes. Patients who are allergic to penicillin may receive tetracycline 500mg twice daily instead of amoxicillin 1mg twice daily. 3
NSAID associated Ulcers and dyspepsia Ulcer Treatment Comments Duodenal Ulcer Gastric Ulcer Continue with full dose of PPI for 4 weeks Continue with full dose of PPI for up to 8 weeks - repeat endoscopy. In both cases: Preferably stop NSAID s / Aspirin If not possible to stop NSAIDs / Aspirin and: 1. H-Pylori positive then confirm with breath test and unless patient high risk should not treat with concurrent PPI and NSAID / aspirin 2. H-Pylori negative then concurrent PPI and NSAID / aspirin. Possible association between concomitant use of PPIs with Clopidogrel reducing the effectiveness of clopidogrel. OR Consider reviewing the clinical need for clopidogrel NSAID associated Ulcers and dyspepsia 20mg daily for 4-8 weeks Can be used prophylatically in patients with a history of NSAID dyspeptic symptoms, associated ulcers or gastroduodenal lesions. 15-30mg daily for 4-8 weeks (or until gastric ulcers healed) Can be used prophylatically in patients with a history of NSAID dyspeptic symptoms, associated ulcers or gastroduodenal lesions at 15-30mg daily. Patients prescribed low dose Aspirin 75mg daily and who are at risk of NSAID associated ulcers should be prescribed a proton pump inhibitor concomitantly instead of replacing aspirin with clopidogrel. Check if H-Pylori positive or negative. Patients requiring a parenteral proton pump inhibitor may be prescribed intravenous omeprazole. 4
Non-ulcer Dyspepsia Domperidone 10mg tablets 10-20mg to be taken three times a day 30 minutes before meals and at night for up to 12 weeks Advise patient of possible side-effects See latest BNF or SPC.
