Q

Let’s talk about 💩…

What is constipation?

A

Passing of dry, hard stools less frequently than a person’s normal bowel habit.

2
Q

What is typical of a ‘normal’ bowel habit?

A

2-3 times/day to 1-2 times/week

3
Q

When would you consider referring someone who presented with constipation?

A

1) dark red/black stools - especially if associated with other symptoms such as weight loss –> indicative of something more sinister like bowel Cancer
2) bright red blood seen on passing stools or when wiping –> ?haemorrhoids
3) > 14 days with no identifiable cause
4) pain when trying to pass stools
5) constipation in addition to following symptoms lethargy, weight gain, mood swings, coarse hair or dry skin –> ? Hypothyroidism
6) drug induced –> opioids, Hyoscine, SSRIs, TCAs, verapamil, propranolol, aluminium containing antacids, iron, chlorphenamine, bendroflumethiazide
7) continuous use of laxatives –> loss of bowel muscle activity –> induces constipation

4
Q

What lifestyle advice would you give to a patient presenting with constipation?

A

Increase fruit and veg intake
Increase wholemeal food intake I.e wholemeal cereals
Increase fluids
Increase regular exercise

5
Q

What is the recommended amount of exercise?

A

150 minutes of moderate aerobic exercise/ week

E.g cycling, brisk walking

Activities which get your heart rate up

+

2 days of strength exercises e.g weights to help maintain strong bones and muscle function

6
Q

What is the treatment protocol for constipation?

A

1st line: lifestyle advice

2nd line: osmotic or bulk forming laxatives

3rd line: stimulant laxatives

7
Q

How do osmotic laxatives exert their therapeutic effect and name some examples which can be purchased from the pharmacy?

A

MOA: increase osmotic pressure in the large bowel by drawing water into the bowel or helping to retain the fluid that is already there.

E.g
lactulose
Macrogols - movicol or laxido

8
Q

What are the main S/E of osmotic laxatives?

A

S/E particularly with lactulose (20% of people experience the following):

Flatulence
Abdominal cramps

9
Q

How do bulk forming laxatives exert their therapeutic effect and name some examples which can be purchased from the pharmacy?

A

MOA: human body does not naturally possess the enzymes to break down active ingredients of bulk forming laxatives –> e.g ispaghula, methylcellulose. This allows the laxative to pass straight through and increase the mass in the large bowel to help stimulate peristalsis. The hydrated material also allows bacteria naturally found in the gut to colonise and help soften stools.

E.g
fybogel - ispaghula
Celevac - methylcellulose

10
Q

How do stimulant laxatives exert their therapeutic effect and name some examples which can be purchased from the pharmacy?

A

MOA: directly stimulates the mucosa of large bowel and rectum; promoting peristalsis and accumulation of water and electrolytes into the intestinal mucosa

E.g
Senokot- Senna
Dulcolax - Bisacodyl

11
Q

What is important to counsel a patient on when they are taking bulk forming laxatives?

A

Drink plenty of fluids to avoid oesophageal and intestinal obstruction

12
Q

How long do the following laxatives take to exert a therapeutic effect?

Osmotic
Bulk forming
Stimulant

A

Osmotic -> 2-3 days
Bulk forming -> 24hrs to 3days
Stimulant -> 6-12hours

13
Q

Ages for use of laxatives in Children.

Methylcellulose > 7yo

Stimulant:
Senna > 2yo
Bisacodyl > 4yo

14
Q

What is diarrhoea?

A

Increased bowel movements of watery or abnormally soft stools.

Usually accompanied by abdominal cramps, nausea and vomiting and lethargy may also occur.

15

E.g diarolyte sachets

1 sachet in 200mL of water
Contains sodium, glucose, potassium, chloride, citrate

Keep well hydrated

2nd line: loperamide 2mg tablets
Opioid receptor analogue/ anti-propulsive

E.g Imodium

17
Q

What is the MOA of loperamide?

A

Opioid receptor analogue. Also known as anti-propulsive.

Binds to opioid receptors in the gut and reduces peristalsis, increases gut transit time and enhancing resorption of water and electrolytes.
Loperamide also increase tone of anal sphincter which helps reduce faecal incontinence and urgency.

18
Q

What counselling points would you give to patients presenting with diarrhoea?

A

1) hand hygiene- always wash hands with soap and dry well with a clean towel
2) avoid drinking fizzy drinks, milk (as temporary lactose intolerance occurs due to damage to intestinal lining cells), fruit as these may all prolong diarrhoea
3) reconstitute powders with boiled and cooled water (recommended)
4) avoid sharing water or drinking untreated water if abroad
5) avoid shellfish and fish unless fresh and from freshwater
6) eat fresh foods, no uncooked meat

19

E.g simple linctus, honey and lemon

24
Q

A

Constipating

36
Q

How do aluminium/ magnesium based antacids exert their therapeutic effect?

A

Patients should be counselled to take medicines at least 2 to 3 hours apart

38
Q

Why is aluminium based antacids not recommended in renal impairment?

A

Due to aluminium based compounds being insoluble in water and mainly excreted in urine, accumulation may occur in the kidneys in patients with renal impairment.

Possibility of aluminium toxicity.

39
Q

How do alginates exert their therapeutic effect?

A

Form a raft which sits on the surface of the stomach contents and prevents reflux.

Some alginate based products contains bicarbonate causes the release of carbon dioxide in the stomach which allows the raft to float more easily on top of the stomach contents.

40
Q

How does ranitidine/famotidine exert their therapeutic effect to reduce the symptoms of heartburn/indigestion?

A

Both are H2 receptor antagonists. Prevents the release of histamine which consequently reduces the effect of H+/K+ ATPase pump - reducing gastric acid secretion

A

Max. 14 days supply

42
Q

How do proton pump inhibitors exert their therapeutic effect?

A

1-3 days

44
Q
