What is dried Aluminium hydroxide gel and magnesium hydroxide tablets used for?
In the pharmaceutical industry, the combination of Dried Aluminium Hydroxide Gel and Magnesium Hydroxide (often referred to as Magaldrate-like combinations or Co-magaldrox) is a high-performance antacid and anti-flatulent therapy. As a pharmacist, I view this specific pairing as the “gold standard” for rapid acid neutralization because it utilizes two of the most potent non-systemic alkalizing agents available.
Primary Clinical Uses
-
Acute Heartburn & Acid Indigestion: Provides near-instant relief from pyrosis (heartburn) by rapidly raising the gastric pH.
-
Peptic & Duodenal Ulcers: Used as a mainstay adjunctive therapy to neutralize stomach acid, allowing the ulcerated mucosa time to heal.
-
Gastroesophageal Reflux Disease (GERD): Specifically effective in reducing the “acid burn” felt in the esophagus during reflux episodes.
-
Hyperphosphataemia: In chronic renal failure, the Aluminum component serves as a phosphate binder to help manage electrolyte balance.
Mechanism of Action
This combination is a classic example of pharmacological synergy:
Magnesium Hydroxide: Acts rapidly to neutralize gastric acid. Its high solubility in stomach acid ensures an immediate onset of action.
Dried Aluminium Hydroxide Gel: Provides a slower, sustained neutralizing effect, extending the duration of relief.
The “Laxative-Constipation” Balance: Aluminum hydroxide alone tends to cause constipation, while Magnesium hydroxide has a laxative effect. By combining them, we achieve a neutral effect on bowel motility, significantly improving patient tolerance for long-term use.
The Manufacturer’s Perspective: Formulation & Export
From a manufacturing standpoint, achieving a high-quality antacid tablet involves balancing chemical reactivity with palatability:
-
Acid Neutralizing Capacity (ANC): As a WHO-GMP manufacturer, we ensure each batch undergoes rigorous ANC testing to guarantee that the milliequivalent of acid neutralized meets BP/USP specifications.
-
Dispersibility: For chewable versions, the tablet must break down quickly into a fine, non-gritty suspension in the mouth to maximize the surface area for acid interaction.
-
Flavoring Technology: Aluminum and Magnesium can have a chalky or metallic aftertaste. We utilize advanced taste-masking agents and cooling mint flavors to ensure the product is palatable for OTC (Over-the-Counter) consumers.
-
Global Export Opportunity: These tablets are high-volume essentials for B2B marketplaces and hospital tenders. Our Mumbai-based facility provides Alu-Alu or PVC/PVDC packaging to ensure stability in the high-humidity environments of export markets.
