3. Pharmaceutical Form
Chewable tablet.
4. Clinical Particulars
4.1 Therapeutic Indications
For relief from indigestion, dyspepsia, heartburn, acidity and flatulence.
4.2 Posology And Method Of Administration
Adults, elderly and children over 12 years:
Take one or two tablets as required. Suck slowly or chew as preferred.
Children below 12 years:
Not recommended.
4.3 Contraindications
Hypophosphataemia, and avoid in patients with heart or renal failure.
4.4 Special Warnings And Precautions For Use
The label will contain the following statements:
1. If symptoms persist, consult your doctor.
2. Keep all medicines out of the reach of children.
3. Not to be taken during the first three months of pregnancy.
4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction
Antacids are known to reduce the absorption of certain medicines including tetracyclines and iron salts.
4.6 Pregnancy And Lactation
No clinical data on exposed pregnancies are available.
Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal/foetal development, parturition or postnatal development (see section 5.3).
Caution should be exercised when prescribing to pregnant women.
4.7 Effects On Ability To Drive And Use Machines
None stated.
4.8 Undesirable Effects
Calcium salts can have a constipating effect and magnesium salts can have a laxative effect. The mixture of antacids is intended to avoid the lower gastrointestinal effects seen with single antacid preparations. No side effects associated with sodium bicarbonate except when taken in excess. Rebound hyperacidity may occur with prolonged dosage.
4.9 Overdose
Hypermagnesaemia – intravenous administration of calcium salts.
Hypernatraemia – give plenty of salt free liquids.
Hypercalcaemia – remove source of calcium.
5. Pharmacological Properties
5.1 Pharmacodynamic Properties
Sodium bicarbonate, calcium carbonate and magnesium carbonate are antacids. They act by neutralising the hydrochloric acid produced by the stomach and thus reducing gastric and duodenal irritation.
Sodium Bicarbonate
Sodium bicarbonate is a rapid onset, short acting antacid which neutralises acid secretions in the gastrointestinal tract by reacting with hydrochloric acid to produce sodium chloride. During neutralisation carbon dioxide is released, facilitating erucation which provides a sense of relief.
Calcium Carbonate
Calcium carbonate is an antacid with a more prolonged effect than sodium bicarbonate. It rapidly reacts with gastric acid to produce calcium chloride.
Magnesium Carbonate
Magnesium carbonate reacts with gastric acid to form soluble magnesium chloride and carbon dioxide. Because of its crystalline structure it reacts less rapidly than sodium bicarbonate giving it a slower onset of action, and providing longer lasting relief.
5.2 Pharmacokinetic Properties
Sodium Bicarbonate
Administration of sodium bicarbonate by mouth causes neutralisation of gastric acid with the production of carbon dioxide. Bicarbonate not involved in that reaction is absorbed and in the absence of a deficit of bicarbonate in the plasma, bicarbonate ions are excreted in the urine that is rendered alkaline with an accompanying diuresis.
Calcium Carbonate
Calcium carbonate is converted to calcium chloride by gastric acid. Some of the calcium is absorbed from the intestines but about 85% is reconverted to insoluble calcium salts, such as the carbonate and is excreted in the faeces.
Magnesium Carbonate
Magnesium carbonate reacts with gastric acid to form soluble magnesium chloride and carbon dioxide in the stomach. Some magnesium is absorbed but is usually excreted rapidly in the urine.
5.3 Preclinical Safety Data
The active ingredients in Bisodol Tablets have a well-established safety record.
