4.1

CLINICAL PARTICULARS
Therapeutic indications For the symptomatic relief of indigestion, heartburn, hyperacidity, flatulence, upset stomach, dyspepsia, biliousness, over indulgence in food and drink, indigestion during pregnancy, acid indigestion, nervous indigestion.

4.2

Posology and method of administration Tablets to be taken orally, sucked or chewed. Adults and children over 12 years: Two tablets to be sucked or chewed as a single dose, preferably to be taken one hour after meals and before going to bed but also in between in case of heartburn or gastric pain. A maximum daily dose of 8 g calcium carbonate, corresponding to 16 tablets, a day must not be exceeded.

Children:

Not recommended for children under 12 years.

As with all antacids, if symptoms persist despite 14 days of continuous therapy, diagnostic measures are strongly recommended in order to rule out a more serious disease.

4.3.

Contraindications
Rennie should not be administered to patients with: Hypersensitivity to any of the ingredients of the product Hypercalcaemia and/or conditions resulting in hypercalcaemia Nephrolithiasis due to calculi containing calcium deposits Severe renal insufficiency Hypophosphataemia

4.4

Special warnings and precautions for use Prolonged use should be avoided. The stated dose should not be exceeded. If, after 14 days of treatment, symptoms persist or only partly disappear, the patient should consult a doctor. Caution should be exercised in patients with mild to moderate impairment of renal function (See section 4.3 contraindication in severe renal insufficiency). If Rennie is used in such patients, plasma calcium and phosphate levels should be regularly monitored. Long term use at high doses can result in undesirable effects such as hypercalcaemia and milk-alkali syndrome, especially in patients with renal insufficiency. Rennie should not be used in patients with hypercalciuria (see also section 4.3). Prolonged use increases the risk of formation of renal calculi. This product should not be taken with large amounts of milk or dairy products. Patients with rare hereditary problems of fructose intolerance, glucosegalactose malabsorption or sucrase-isomaltase insufficiency should not take this medicine. Ponceau 4R (E124) may cause allergic reactions. Interaction with other medicinal products and other forms of interaction Changes in gastric acidity, such as that caused by the ingestion of antacids, can affect the rate and degree to which some concurrently administered medicines are absorbed.





4.5



It has been shown that antacids which contain calcium may form complexes with certain substances e.g., antibiotics (such as tetracyclines and quinolones), and cardiac glycosides (e.g. digoxin), levothyroxine, and eltrombopag, resulting in decreased absorption. This should be borne in mind when concomitant administration is considered. Calcium salts can impede the absorption of phosphates, fluorides and iron-containing products. Thiazide diuretics reduce the urinary excretion of calcium. Due to an increased risk of hypercalcaemia, serum calcium should be regularly monitored during concomitant use of thiazide diuretics.



Therefore it is preferable to take the antacid separately from other drugs, allowing at least 4 hours before or after taking eltrombopag and a 1-2 hour interval for all other drugs.

4.6.

Fertility, pregnancy and lactation
No increased risk of congenital defects has been observed after the use of this product during pregnancy and it can be used during pregnancy and lactation if taken as instructed but prolonged intake of high dosages should be avoided. Pregnant women should limit the use of these products to the maximum recommended daily doses (see Section 4.2). During pregnancy and lactation, it has to be taken into account that the tablets provide a substantial amount of calcium in addition to dietary calcium intake. For this reason, pregnant women should strictly limit their use of tablets to the maximum recommended daily dose and avoid concomitant, excessive intake of milk and dairy products. This warning is to prevent calcium overload which might result in milkalkali syndrome.

4.7

Effects on ability to drive and use machines No effects on ability to drive and use machines have been observed.

4.8.

Undesirable effects
The listed adverse drug reactions are based on spontaneous reports, thus an organisation according to CIOMS III categories of frequency is not possible. Immune System Disorders: Hypersensitivity reactions have very rarely been reported. Clinical symptoms may include rash, urticaria, angioedema and anaphylaxis. Metabolism and Nutrition Disorders:

Especially in patients with impaired renal function, prolonged use of high doses can result in hypercalcaemia and alkalosis which may give rise to gastric symptoms and muscular weakness (see below). Gastrointestinal Disorders: Nausea, vomiting, stomach discomfort and diarrhoea may occur. Musculoskeletal and Connective Tissue Disorders: Muscular weakness may occur. Undesirable effects occurring in the context of milk-alkali syndrome (see 4.9): Gastrointestinal Disorders: Ageusia may occur in the context of milk-alkali syndrome. General Disorders and Administration Site Conditions: Calcinosis and asthenia may occur in the context of milk-alkali syndrome. Nervous System Disorders: Headache may occur in the context of milk-alkali syndrome. Renal and Urinary Disorders: Azotemia may occur in the context of milk-alkali syndrome.

4.9

Overdose
Especially in patients with impaired renal function, prolonged use of high doses of calcium carbonate can result in renal insufficiency, hypercalcaemia and alkalosis which may give rise to gastrointestinal symptoms (nausea, vomiting, constipation) and muscular weakness. In these cases, the intake of the product should be stopped and adequate fluid intake encouraged. In severe cases of overdosage (e.g. milk-alkali syndrome), a health care professional must be consulted because other measures of rehydration (e.g. infusions) might be necessary.

PHARMACOLOGICAL PROPERTIES
Pharmacodynamic properties

Pharmacotherapeutic Classification: Antacids ATC codes: Calcium carbonate: A02AC01 Calcium carbonate reacts with excess acid in the gastric juice to produce soluble chloride. CaCO3 +2HCl CaCl2 + H2O + CO2

Calcium carbonate has a rapid and powerful neutralising action.

In healthy volunteers, a significant increase in the pH of stomach contents above baseline pH was achieved between 1 and 6 minutes after dosing.

5.2

Pharmacokinetic properties A small amount of calcium may be absorbed, but in healthy subjects is usually rapidly excreted by the kidney. The soluble chloride produced by the reaction of calcium with gastric acid reacts, in turn, with intestinal, biliary and pancreatic secretions to form insoluble salts, which are excreted in the faeces.

5.3.
