1. Clinical Overview
A quadruple-action oral suspension for the symptomatic management of hyperacidity, gastroesophageal reflux disease (GERD), and associated dyspepsia. It combines a potent local anesthetic (oxetacaine) for rapid pain relief, two antacids (aluminium hydroxide and magnesium hydroxide) for acid neutralization, and an antiflatulent (simethicone) for gas relief. It is a first-line therapy for immediate relief of acid-peptic symptoms in the Indian outpatient setting.
| Onset | Duration | Bioavailability |
|---|---|---|
| Oxetacaine: 30-60 seconds; Antacids: 1-5 minutes; Simethicone: 1-2 minutes. | Oxetacaine: 1-2 hours; Antacids: 1-3 hours; Simethicone: 2-4 hours. | Oxetacaine: Topical/local, negligible systemic absorption. Aluminium/Magnesium: Minimal systemic absorption (<1% for Al, ~15-30% for Mg). Simethicone: Not absorbed, acts locally in the GI tract. |
2. Mechanism of Action
1. Oxetacaine: A potent surface anesthetic that blocks sodium channels in the neuronal membrane of the esophageal and gastric mucosa, providing rapid relief from pain and burning sensation. 2. Aluminium Hydroxide & Magnesium Hydroxide: Non-systemic antacids that react with and neutralize hydrochloric acid in the gastric lumen, raising the pH. They also adsorb pepsin and bile salts. 3. Simethicone: A physiologically inert antifoaming agent that reduces the surface tension of gas bubbles in the GI tract, causing them to coalesce and be more easily expelled via belching or flatus.
3. Indications & Uses
- Symptomatic relief in gastroesophageal reflux disease (GERD)
- Relief of heartburn, acid indigestion, and sour stomach
- Symptomatic management of gastritis and esophagitis
- Immediate relief of dyspepsia associated with hyperacidity
4. Dosage & Administration
Adult Dosage: 10-20 ml (2-4 teaspoonfuls) orally, 3-4 times a day, 20-60 minutes after meals and at bedtime, or as directed by the physician. Do not exceed 80 ml (16 teaspoonfuls) in 24 hours.
Administration: Shake the bottle well before use. Use the measuring cup/spoon provided. To be taken undiluted or with a small amount of water. Do not take with other liquids like milk. Maintain an upright position for 1-2 minutes after administration. Allow at least 2 hours gap between taking this suspension and other oral medications (especially tetracyclines, fluoroquinolones, iron supplements, levothyroxine, azole antifungals, etc.) to avoid adsorption and reduced absorption.
5. Side Effects
Common side effects may include:
- Chalky taste
- Mild constipation or mild diarrhea (depending on individual sensitivity to Al/Mg ratio)
- White speckling in stools
6. Drug Interactions
| Drug | Effect | Severity |
|---|---|---|
| Tetracyclines (Doxycycline, Tetracycline) | Markedly decreased absorption due to chelation with Al & Mg cations. | Major |
| Fluoroquinolones (Ciprofloxacin, Levofloxacin) | Markedly decreased absorption due to chelation. | Major |
| Iron Supplements (Ferrous sulfate) | Decreased absorption of iron. | Moderate |
| Levothyroxine | Decreased absorption of levothyroxine. | Moderate |
| Azole Antifungals (Ketoconazole, Itraconazole) | Decreased absorption due to increased gastric pH. | Major |
| Digoxin | Altered absorption; monitor digoxin levels. | Moderate |
| Phosphate supplements | Aluminium hydroxide binds phosphate, reducing its efficacy. | Moderate |
| Enteric-coated medications | Premature dissolution in less acidic stomach, causing gastric irritation. | Moderate |
| Sodium Polystyrene Sulfonate | Risk of intestinal necrosis (with aluminium hydroxide). | Major |
| Neuromuscular Blockers (e.g., Succinylcholine) | Magnesium may potentiate effects. | Moderate |
7. Patient Counselling
- DO shake the bottle well before each use.
- DO use the measuring device provided.
- DO take it 20-60 minutes after meals and at bedtime for best results.
- DO maintain a 2-hour gap between this medicine and any other oral medication.
- DO inform your doctor if you are pregnant, planning pregnancy, or breastfeeding.
- DO NOT take it for more than 2 weeks continuously unless advised by your doctor.
- DO NOT take it if you have symptoms of appendicitis (severe abdominal pain with nausea/vomiting).
- DO NOT take it with milk or dairy products.
8. Toxicology & Storage
Overdose: Symptoms are primarily related to magnesium and aluminium toxicity: Severe diarrhea or constipation, lethargy, muscle weakness, hypotension, respiratory depression, ECG changes, confusion, osteomalacia, encephalopathy (in renal impairment).
Storage: Store at room temperature (15-30°C). Protect from light and moisture. Keep the bottle tightly closed. Keep out of reach of children. Do not freeze. Discard any unused suspension 4 weeks after opening the bottle, unless otherwise stated on the packaging.
