4 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. 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
Adults and children 12 years and over: 5–10 ml after meals and at bedtime
Children under 12 years: Should be given only on medical advice
Elderly: No dose modification is required for this age group.
Hepatic Impairment: No dose modification necessary.
Renal Insufficiency: Caution if highly restricted salt diet is necessary (see section 4.4).
4.3 Contrindications
This medicinal product is contraindicated in patients with known or suspected hypersensitivity to any of the ingredients, or any of the excipients listed in section 6.1, including methyl parahydroxybenzoate (E218) and propyl parahydroxybenzoate (E216) (see section 4.4).
4.4 Special warnings and precautions for use
If symptoms do not improve after 7 days, the clinical situation should be reviewed.
This medicinal product contains 106 mg (5.0 mmol) sodium per 10 ml dose, equivalent to 5.3% of the WHO recommended maximum daily intake for sodium.
The maximum daily dose of this product is equivalent to 21% of the WHO recommended maximum daily intake for sodium.
This product is considered high in sodium. This should be particularly taken into account for those on a low salt diet (e.g. in some cases of congestive heart failure and renal impairment).
Potassium: This medicine contains 78 mg (2.0 mmol) potassium per 10 ml dose. To be taken into consideration by patients with reduced kidney function or patients on a controlled potassium diet.
Each 10 ml 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.
Contains methyl parahydroxybenzoate (E218) and propyl parahydroxybenzoate (E216): May cause allergic reactions (possibly delayed).
4.5 Interaction with other medicinal products and other forms of interaction
A time-interval of 2 hours should be considered between Gaviscon intake and the administration of other medicinal products, especially tetracyclines, fluoroquinolones, iron salts, thyroid hormones, chloroquine, bisphosphonates, and estramustine.
4.6 Fertility, pregnancy and lactationPregnancy:
Clinical studies in more than 500 pregnant women as well as a large amount of data from post-marketing experience indicate no malformative nor foeto/neonatal toxicity of the active substances. Gaviscon can be used during pregnancy, if clinically needed.
No known effect on breast fed infants. Gaviscon can be used during breast feeding.
No known effect on human fertility.
4.7 Effects on ability to drive and use machines

5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic classification: A02E A01 Anti-regurgitant
On ingestion the suspension 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 it structure, further protecting the oesophagus from these gastric components.
5.2 Pharmacokinetic properties
The mode of action of Gaviscon Advance Aniseed Suspension is physical and does not depend on absorption into the systemic circulation.
5.3 Preclinical safety data
5.3 Preclinical safety dataNo preclinical findings of relevance to the prescriber have been reported.
