How to use dried aluminium hydroxide gel?
In the pharmaceutical industry, Dried Aluminium Hydroxide Gel is a primary antacid frequently formulated as chewable tablets or oral suspensions. As a pharmacist and manufacturer, I view its administration as a “balancing act”—it requires specific timing and patient behavior to maximize its acid-neutralizing capacity without interfering with other therapeutic regimens.
At your WHO-GMP facility in Mumbai, educating your B2B clients on the correct usage of this SKU is vital for ensuring the therapeutic efficacy of your gastrointestinal portfolio.
Clinical Administration Guidelines
To achieve the best results, the timing of the dose is more important than the dose itself.
-
Optimal Timing: It should be taken between meals (usually 1 to 3 hours after eating) and at bedtime. Taking it after meals extends its neutralizing effect from 30 minutes to nearly 3 hours, as the food in the stomach slows down gastric emptying.
-
Tablet Usage: Chewable tablets must be chewed thoroughly before swallowing. This increases the surface area of the gel, allowing for faster and more complete neutralization of stomach acid.
-
Suspension Usage: If using the liquid form, the bottle must be shaken vigorously to ensure the “gel” is evenly distributed, providing a consistent dose of the active ingredient.
Mechanism: Local Acid Neutralization
Chemical Reaction: The gel reacts with the Hydrochloric Acid (HCl) in the stomach to produce Aluminium Chloride and water. This raises the gastric pH above 3.5, which is sufficient to relieve the “burn” of acidity.
Pepsin Adsorption: Beyond simple neutralization, the gel adsorbs pepsin (the stomach’s protein-digesting enzyme), which helps protect the esophageal and gastric lining from further irritation.
Non-Systemic Action: Because it is poorly absorbed from the gastrointestinal tract, its action is primarily local, making it a safer profile for short-term use compared to systemic alkalizers.
The Pharmacist’s “Technical Warning”
-
The 2-Hour “No-Drug” Window: Because Aluminium Hydroxide gel is highly reactive, it can bind to and prevent the absorption of other critical drugs like Digoxin, Iron salts, Tetracyclines, and Ciprofloxacin. Advise patients to wait at least 2 hours before or after taking other medications.
-
Fluid Intake: Encourage patients to follow the dose with a small amount of water to help the gel reach the stomach, but avoid excessive water, which can dilute the antacid effect.
-
Constipation Management: Since aluminum-only gels are famously constipating, pharmacists often suggest increasing dietary fiber or fluid intake if the patient is not using a combined formula (like Magnesium + Aluminium).
The Manufacturer’s Perspective: Technical & Export
From a production and B2B standpoint at your facility in Mumbai:
-
The “Gel vs. Powder” Distinction: For your marketplace, clarify that “Dried Gel” is specifically processed to maintain high acid-neutralizing capacity (ANC) compared to standard aluminum hydroxide powder. B2B buyers look for high ANC values in the Certificate of Analysis (CoA).
-
Stability for Export: In liquid form, the gel is prone to phase separation in extreme temperatures. For export to Zone IVb tropical regions, ensure your formulation contains the correct stabilizers (like Xanthan gum or Sorbitol) to maintain a smooth consistency.
