NAME OF THE MEDICINAL PRODUCT
Gaviscon Peppermint Flavour Tablets.
QUALITATIVE AND QUANTITATIVE COMPOSITION
Each tablet contains sodium alginate 250 mg, sodium hydrogen carbonate 133.5 mg and calcium carbonate 80 mg. Excipients: Aspartame (E951) 3.75 mg per tablet. For excipients, see Section 6.1.
Chewable tablet. An off-white to cream, slightly mottled tablet.
Therapeutic indications Treatment of symptoms of gastro-oesophageal reflux such as acid regurgitation, heartburn and indigestion (related to reflux), for example, following meals or during pregnancy or in patients with symptoms related to reflux oesophagitis.
Posology and method of administration For oral use, after being thoroughly chewed. Adults and children 12 years and over: Two to four tablets after meals and at bedtime. Elderly: No dose modifications necessary for this age group.
Contraindications This medicinal product is contraindicated in patients with known or suspected hypersensitivity to the active substances or to any of the excipients. Special warnings and precautions for use The sodium content of a four-tablet dose is 246 mg (10.6 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. Each four-tablet dose contains 320 mg (3.2 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 medicinal product should not be given to patients with phenylketonuria. 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.
Interaction with other medicinal products and other forms of interaction Due to the presence of calcium carbonate which acts as an antacid, a timeinterval of 2 hours should be considered between Gaviscon intake and the administration of other medicinal products, especially H2-antihistaminics, tetracyclines, digoxine, fluoroquinolone, iron salt, ketoconazole, neuroleptics, thyroxine, penicilamine, beta-blockers (atenolol, metoprolol, propanolol), glucocorticoid, chloroquine and diphosphonates. Pregnancy and lactation Open controlled studies in 281 pregnant women did not demonstrate any significant adverse effects of Gaviscon on the course of pregnancy or on the health of the foetus/new-born child. Based on this and previous experience the medicinal product may be used during pregnancy and lactation. Nevertheless,
taking into account the presence of calcium carbonate (see Section 5.3) it is recommended to limit the treatment duration as much as possible. 4.7 Effects on ability to drive and use machines Not relevant. Undesirable effects Very rarely (=1/10,000) patients may develop allergic manifestations such as urticaria or bronchospasm, anaphylactic and anaphylactoid reactions. Overdose In the event of overdose symptomatic treatment should be given. The patient may notice abdominal distension.
Pharmacotherapeutic group: Other drugs for peptic ulcer and gastrooesophageal reflux disease (GORD) ATC code: A02BX. On ingestion the medicinal product reacts rapidly with gastric acid to form a raft of alginic acid gel having a near neutral pH and which floats on the stomach contents, quickly and effectively impeding gastro-oesophageal reflux, for up to 4 hours. In severe cases the raft itself may be refluxed into the oesophagus, in preference to the stomach contents, and exert a demulcent effect.
Pharmacokinetic properties The mechanism of action of the medicinal product is physical and does not depend on absorption into the systemic circulation.
Preclinical safety data There is limited evidence in some reports in animals of delay in calcification of foetal skeleton/bone abnormalities relating to calcium carbonate.
