- Review medications as possible cause

4

Urgent specialist referral, is indicated for patients of any age with dyspepsia when presenting with certain alarm symptoms. list some of these alarm symptoms

A

Urgent referral for endoscopic investigation:

1) Chronic GI bleed
2) Progressive, unintentional weight loss
3) Progressive difficulty swallowing
4) Persistent vomiting
5) Iron deficient anaemia
6) Epigastric mass
7) Suspicious barium meal

A

1) Age >55
2) L significant and unintentional weight loss
3) Anemia
4) Recurrent vomiting/difficulty swallowing
5) Malaena - dark sticky faeces containing partly digested blood

6
Q

what Medicines can be used to treat dyspepsia?

A

1) Antacids (contain aluminium or magnesium)
- Best given when symptoms occur or are expected: With meals/bedtime
2) Magnesium = laxative
3) Aluminium = constipating
4) Alginates
- Increases the viscosity of the stomach contents taken in combination with antacids
- Protects against acid-reflux - Raft

7
Q

what effect do antacids have on EC tablets?

A

Antacids damage enteric coatings designed to prevent dissolution in the stomach

8
Q

discuss what you should consider when recommending a particular formulation for the treatment of dyspepsia to a consumer.

A

1) Patient choice
2) Practicality- do they want tablets or a liquid?
3) Taste!
4) Effectiveness- double action?

9
Q

A

1) Smoking
2) Alcohol
3) Coffee
4) Chocolate
5) Fatty foods

7) Raise head of bed
8) Don’t eat too late

11
Q

what is GORD?

  • who is normally affected?
  • what is the treatment?
A

1) gastro-oesophageal reflux disease refers to endoscopically determined oesophagitis or endoscopy-negative reflux disease.
2) GORD is a common digestive condition.
3) Adults aged 40 years or over are mainly affected
4) Offer patients who have GORD a full-dose PPI for 1 or 2 months.
5) If symptoms recur – low dose PPI

12
Q

Discuss the causes of GORD and outline the known risk factors

A

1) Most common is the failure of the lower oesophageal sphincter (LOS)
2) This acts like a valve, opening to let food fall into the stomach, then closing to prevent acid leaking out of the stomach back into the oesophagus.
3) In GORD, this sphincter doesn’t close properly, allowing acid to leak up out of the stomach.
4) Known risk factors for GORD include:
- being overweight or obese
- being pregnant
- eating a high-fat diet

13
Q

outline the role of a pharmacist in the treatment of GORD

A

1) advice regarding lifestyle factors that may affect reflux:
- Smaller meals, eat earlier in the evening
- Weight management
- Smoking cessation
- If practical, advise the person to try raising the head of their bed
- Stress management
2) Review the person’s medication and, if possible, avoid drugs that may cause or exacerbate symptoms.

14
Q

list the drugs that reduce lower oesophageal sphincter pressure

A

1) Theophylline
2) nitrates
3) calcium-channel blockers
4) beta-blockers
5) alpha-blockers
6) benzodiazepines
7) tricyclic antidepressants
8) anticholinergics

15
Q

how do PPI’s work and why should you use them with caution?

- what is the dosage and treatment period?

A

1) Inhibit gastric secretion by blocking hydrogen-potassium adenosine triphosphatase enzyme system
2) Caution: can mask signs of gastric cancer – ALARM
3) Prescribed at lowest effective dose and for shortest period of time

16
Q

what are the side effects of PPI’s?

A

1) GI disturbances,
2) Rarely: hyponatraemia and hypomagnesaemia (usually >1 year)
3) By reducing gastric acidity = increased risk of GI infections for example Clostridium difficile.
4) Increased risk of fractures, particularly in elderly

17
Q

list 3 PPI’s and state their doses

A

1) Esomeprazole: 40mg OD 4 weeks (max 8 weeks) then 20mg OD
2) Lansoprazole: 30mg OD 4 weeks (max 8 weeks) then 15-30mg OD
