CLINICAL PARTICULARS

4.1

Therapeutic indications
Treatment of symptoms resulting from the reflux of acid, bile and pepsin into the
oesophagus such as acid regurgitation, heartburn, indigestion (occurring due to the
reflux of stomach contents), for instance, after gastric surgery, as a result of hiatus
hernia, during pregnancy, accompanying reflux oesophagitis, including symptoms of
laryngopharyngeal reflux such as hoarseness and other voice disorders, sore throats

and cough. It can also be used to treat the symptoms of gastro-oesophageal reflux
during concomitant treatment with or following withdrawal of acid suppressing
therapy.

4.2

Posology and method of administration
For oral administration, after being thoroughly chewed.
Adults and children 12 years and over: One to two tablets after meals
and at bedtime.
Children under 12 years: Should be given only on medical advice.
Elderly: No dose modifications necessary for this age group.

4.3

Contraindications
This medicinal product is contraindicated in patients with known or suspected
hypersensitivity to the active substances or to any of the excipients.

4.4

Special warnings and precautions for use
The sodium content of a two-tablet dose is 103 mg (4.5 mmol) and a
potassium content of 78 mg (2.0 mmol). This should be taken into account
when a highly restricted salt diet is recommended, e.g. in some cases of
congestive cardiac failure and renal impairment or when taking drugs which
can increase plasma potassium levels.
Each two-tablet dose contains 200 mg (2.0 mmol) of calcium carbonate. Care
needs to be taken in treating patients with hypercalcaemia, nephrocalcinosis
and recurrent calcium containing renal calculi.
Due to its aspartame content this product should not be given to patients with
phenylketonuria.
May cause central nervous system depression in the presence of renal
insufficiency and should not be used in patients with renal failure.
There is a possibility of reduced efficacy in patients with very low levels of
gastric acid.
If symptoms do not improve after seven days, the clinical situation should be
reviewed.

Treatment of children younger than 12 years of age is not generally
recommended, except on medical advice.

4.5

Interaction with other medicinal products and other forms of interaction
None known.

4.6

Pregnancy and lactation
An open controlled study in 146 pregnant women did not demonstrate any
significant adverse effects of Gaviscon Advance on the course of pregnancy or
on the health of the foetus/new-born child.
Based on this and previous experience, Gaviscon Advance Tablets may be
used during pregnancy and lactation. Nevertheless, taking into account the
presence of calcium carbonate it is recommended to limit the treatment
duration as much as possible.

4.7

Effects on ability to drive and use machines
None.

4.8

Undesirable effects
Very rarely (<1/10,000) patients may develop allergic manifestations such as
urticaria or bronchospasm, anaphylactic or anaphylactoid reactions.

4.9

Overdose
In the event of overdosage symptomatic treatment should be given. The patient
may notice abdominal distension.

PHARMACOLOGICAL PROPERTIES

5.1

Pharmacodynamic properties
Pharmacotherapeutic classification: A02BX 13. Other drugs for peptic ulcer and
gastro-oesophageal reflux disease.
On ingestion the tablet reacts with gastric acid to rapidly form a raft of alginic
acid gel having a near-neutral pH which floats on the stomach contents effectively
impeding gastro-oesophageal reflux for up to 4 hours, and protecting the oesophagus
from acid, pepsin and bile. In severe cases the raft itself may be refluxed into the
oesophagus in preference to the stomach contents and exert a demulcent effect. In
addition in vitro evidence has shown that the raft has a secondary action and is able to
entrap bile and pepsin within its structure, further protecting the oesophagus from
these gastric components.

5.2

Pharmacokinetic properties
The mode of action of Gaviscon Advance Tablets is physical and does not
depend on absorption into the systemic circulation.

5.3

Preclinical safety data
No pre-clinical findings of any relevance to the prescriber have been reported.
