🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by two complementary mechanisms. Magaldrate neutralises gastric acid chemically, raising gastric pH and reducing the irritant effect of acid on the oesophageal and gastric mucosa. Simethicone acts physically as a surfactant, lowering the surface tension of gas bubbles in the gastrointestinal tract so that smaller bubbles coalesce and are expelled more easily. Together they provide symptomatic relief from acid-related discomfort and gas-related bloating.
Mechanism Steps
💡 How to Take Simag Syrup
Strength: Oral gel containing magaldrate 400 mg and simethicone 50 mg per 5 mL or as per label.
Dosage Information
| Adult Dosage | The usual adult dose is 5 to 10 mL of the oral gel taken between meals and at bedtime, or as directed by your doctor.

Overdose may cause diarrhoea, constipation, abdominal pain, or electrolyte disturbances. In severe cases, especially with kidney impairment, hypermagnesaemia or aluminium toxicity may occur. Treatment is supportive and symptomatic. Seek immediate medical attention if a large amount is ingested. Do not induce vomiting unless advised by a healthcare professional.
⏰ Missed Dose
This medicine is usually taken on an as-needed basis. If you are on a scheduled dose and miss it, take it as soon as you remember. If it is almost time for the next dose, skip the missed dose and continue with your regular schedule. Do not double the dose to make up for a missed one.
Additional Safety Advice
Take this medicine exactly as advised by your doctor or pharmacist. Shake the oral gel well before each use and measure the dose with the supplied spoon or cup. Do not exceed the recommended dose or duration without medical advice. Maintain a gap of at least two hours between this medicine and other oral medicines, because antacids can reduce absorption of many drugs.
