Magnesium trisilicate is an inorganic compound that is used as an antacid in the treatment of peptic ulcers.

Magnesium trisilicate works by increasing the pH of gastric juice via a neutralisation reaction. It also precipitates colloidal silica, which can coat gastrointestinal mucosa conferring further protection.

Sodium bicarbonate is a systemic alkalinizing agent. It increases plasma bicarbonate, buffers excess hydrogen ion concentration, and raises blood pH, thereby reversing the clinical manifestations of acidosis. It can also be used to replenish electrolyte imbalance as a treatment adjunct for severe diarrhea where the loss of bicarbonate can be significant.

Intravenous sodium bicarbonate therapy increases plasma bicarbonate, buffers excess hydrogen ion concentration, raises blood pH and reverses the clinical manifestations of acidosis.

How Sofamag works

The gelatinous silicon dioxide, formed by the reaction of magnesium trisilicate with gastric contents is said to protect ulcerated mucosal surfaces and favor healing.

Sodium bicarbonate is a systemic alkalizer, which increases plasma bicarbonate, buffers excess hydrogen ion concentration, and raises blood pH, thereby reversing the clinical manifestations of acidosis. It is also a urinary alkalizer, increasing the excretion of free bicarbonate ions in the urine, thus effectively raising the urinary pH. By maintaining an alkaline urine, the actual dissolution of uric acid stones may be accomplished. Sodium bicarbonate acts as an antacid and reacts chemically to neutralize or buffer existing quantities of stomach acid but has no direct effect on its output. This action results in increased pH value of stomach contents, thus providing relief of hyperacidity symptoms. [PharmGKB]

Dosage

Sofamag dosage

Oral: The usual dose is 300 mg to 2 grams, 1 to 4 times daily.

Intravenous (Severe metabolic acidosis):

  • Adult: By slow inj of a hypertonic solution of up to 8.4% (1000 mmol/L), or by continuous infusion of a weaker solution, usually 1.26% (150 mmol/L). For correction of acidosis during advanced cardiac life support procedures, 50 ml of an 8.4% solution may be given.
  • Elderly: Dosage adjustments may be required.

Side Effects

This medication is generally well tolerated. However, high doses may cause headache, nausea or irritability. If any of these effects continue or become bothersome, inform your doctor. Notify your doctor if you develop: muscle weakness, slow reflexes, confusion, swelling of the feet or ankles, black tar-like stools, coffee-ground vomit. If you notice other effects not listed above, contact your doctor or pharmacist.

Toxicity

Adequate doses of magnesium trisilicate may cause diarrhea due to the action of soluble magnesium salts in the enteric tract. Approx 5% of the magnesium is absorbed.

Precaution

Pre-existing heart disease, kidney disease, liver disease, high blood pressure, any allergies.

Interaction

This medication has the potential to interact with many medications. Should not take any other medication within 1 to 2 hours of taking an antacid. Potentially hazardous interactions with Corticosteroids and Corticotropin, Alkalis, Calcium, Diuretics and Potassium.

Volume of Distribution

The hydrated silicon dioxide formed in the stomach and passes into the intestinal track.

Elimination Route

The hydrated silicon dioxide formed in the stomach and passes into the intestinal track where, silica can be partly absorbed.

Half Life

16-20 hours

Clearance

Maximum magnesium clearance is directly proportional to creatinine clearance.

Elimination Route

Excreted in the urine.

Pregnancy & Breastfeeding use

Category C: Either studies in animals have revealed adverse effects on the foetus (teratogenic or embryocidal or other) and there are no controlled studies in women or studies in women and animals are not available. Drugs should be given only if the potential benefit justifies the potential risk to the foetus.

Contraindication

This drug is contraindicated in hypoventilatory states, chloride depletion owing to continuous gastric fluid loss, metabolic and/or respiratory alkalosis, hypocalcemia and diuretics known to produce hypochloremic alkalosis.

Acute Overdose

If alkalosis results, the bicarbonate should be stopped and the patient managed according to the degree of alkalosis present. 0.9% sodium chloride injection intravenous may be given; potassium chloride also may be indicated if there is hypokalemia. Severe alkalosis may be accompanied by hyperirritability or tetany and these symptoms may be controlled by calcium gluconate. An acidifying agent such as ammonium chloride may also be indication in severe alkalosis.

Storage Condition

Store in a cool & dry place protected from light. Keep out of reach of children.
