4.4 Special warnings and precautions for use

Because of the sodium content, frequent use by patients on a low sodium diet should be avoided. This includes patients with hypertension and cardiac or renal dysfunction. Magnesium salts may cause central nervous depression in patients with renal dysfunction.

Because of the sucrose content, diabetics should use with caution. Patients with rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase insufficiency should not take this medicine.

If a laxative is required every day, if there is persistent abdominal pain, or if symptoms persist consult your doctor. Prolonged continuous use is not recommended.

4.5 Interaction with other medicinal products and other forms of interaction

Magnesium sulphate, in common with other magnesium salts, may interfere with the absorption of tetracycline and alkalinisation of the urine may modify excretion of drugs for which the excretion is pH sensitive.

5. PHARMACOLOGICAL PROPERTIES

Go to top of the page
5.1 Pharmacodynamic properties

Sodium bicarbonate exerts an immediate antacid effect in the stomach by neutralising acid secretion with the liberation of carbon dioxide.

Citric acid and sodium bicarbonate in solution have a buffering capacity which alleviates discomfort caused by excess acidity in the stomach.

Magnesium sulphate is not readily absorbed from the intestine and acts as a saline purgative. Magnesium ions in the gut have also been shown to cause secretion of cholecystokinin which favours intraluminal accumulation of water and electrolytes.


Go to top of the page
5.2 Pharmacokinetic properties

The product has a local gastrointestinal action and so detailed pharmacokinetic data are not available. It has been shown that less than 10% of ionic magnesium is absorbed when the product was given to healthy subjects. The magnesium that is absorbed is excreted by the kidney.

After absorption, the bicarbonate is retained by the kidney to meet any deficit of bicarbonate in the plasma.

Citric acid is absorbed by the gastrointestinal tract and is oxidised in the body to carbon dioxide and water.
