Q

What is Peptic Ulcer Disease (PUD)?
What are the Causes? (3)
How can you confirm this disease?

A

Ulcers may be present in stomach or duodenum

Causes:
* Helicobacter pylori infection
* Medication, mainly NSAIDs (others can cause them)
* Zollinger-Ellison syndrome (rare condition causing high acid secretion)

  • Can only confirm ulcers with endoscopy
  • H. pylori infection managed with eradication therapy (2 antibiotics and a PPI)
  • Therefore wouldn’t be managed OTC
  • However, patients frequently present asking for symptomatic relief

Q

What is Alginate?
Example?

A

Alginate: Form a ‘raft’ on top of stomach contents, creating a physical barrier to prevent reflux
* Example: sodium alginate

Gaviscon Advance®

18
Q

Dyspepsia – H2 receptor antagonists

A

Ranitidine and famotidine available OTC
*Longer duration of action and longer onset of action than antacids
*Block H2 receptors in stomach to prevent acid production
*For the short-term symptomatic relief of dyspepsia
*Also to prevent symptoms arising if associated with food or drink
consumption when they cause sleep disturbances

19
Q

Dyspepsia – proton pump inhibitors

A

*PPIs block proton pumps in stomach wall to prevent gastric acid
production
*Takes 1-4 days to work fully, so may need to cover with antacids until
it kicks in
*Esomeprazole:
*Common s/e: GI disturbances, headache, abdo pain
*Can increase risk of GI infections such as Campylobacter

20
Q

When to refer a patient with symptoms of Dyspepsia:
Red flags?

A

*Beware of patients frequently attending for dyspepsia remedies

*Dyspepsia hasn’t responded to treatment
*Features including bleeding, dysphagia, recurrent vomiting or
unintentional weight loss

21
Q

Nausea and vomiting

Start treatment with bulk-forming laxative
If stools remain hard, add on or switch to an osmotic laxative

Adjust doses according to symptoms and response
Advise that laxatives should be stopped once the stool becomes soft and passes easily.
