In short
This article discusses clinical trials investigating the use of Aluminium Oxide, Hydrated, a component of antacid medications, in strategies to reduce or discontinue proton pump inhibitor (PPI) use in patients with heartburn, reflux, or dyspepsia. The trials aim to determine the most effective approach for stopping chronic PPI therapy in primary care patients, comparing on-demand use, alginate therapy, and gradual dose reduction.

What is Aluminium Oxide, Hydrated?
Aluminium oxide, hydrated is an active ingredient commonly found in antacid medications. It is often combined with other substances, such as magnesium hydroxide, to create more effective antacid formulations. These combinations are designed to neutralize stomach acid and provide relief from various digestive symptoms.
Aluminium oxide is also known by its synonym, alumina. This substance, along with its combinations, belongs to a class of medications called antacids, which are used to treat various digestive issues.
Medical Uses
Aluminium oxide, hydrated, in combination with other substances, is primarily used to treat the following conditions:
- Heartburn: A burning sensation in the chest often caused by stomach acid flowing back into the esophagus.
- Acid reflux: A condition where stomach contents flow back into the esophagus, causing discomfort and potential damage.
- Dyspepsia: Also known as indigestion, this is a general term for digestive discomfort, including symptoms like bloating, nausea, and upper abdominal pain.
- Functional dyspepsia: A specific type of dyspepsia where symptoms persist but no obvious cause can be found through standard diagnostic tests.
These medications work by neutralizing excess stomach acid, which can help alleviate symptoms and provide relief to patients suffering from these digestive issues.
Available Formulations
Aluminium oxide, hydrated is available in various formulations, often combined with other active ingredients. Some common products include:
- Maalox Antacid® 200 mg/400 mg chewable tablets: Contains aluminium oxide, hydrated and magnesium hydroxide.
- Maalox Antacid® Lemon 230 mg/400 mg per 4.3 ml oral suspension: Contains aluminium oxide (hydrated and non-hydrated forms) and magnesium hydroxide.
- Maalox Antacid® Sugar-free Lemon 200 mg/400 mg chewable tablets: Contains aluminium oxide, hydrated and magnesium hydroxide.
These different formulations allow patients to choose the most suitable option based on their preferences and needs.
Dosage and Administration
The dosage of aluminium oxide, hydrated products can vary depending on the specific formulation and the patient's needs. However, based on the information provided in the clinical trial data, some general guidelines can be inferred:
- The maximum daily dose is typically 8 units (tablets or doses of oral suspension).
- The maximum total dose over a treatment period is usually 248 units.
- The maximum treatment period is generally around 31 days.
It's important to note that these are general guidelines, and patients should always follow the specific instructions provided by their healthcare provider or the product label.
Deprescribing Strategies
For patients who have been using antacids or related medications like proton pump inhibitors (PPIs) for an extended period, healthcare providers may consider deprescribing strategies. These strategies aim to reduce or discontinue the use of these medications when they are no longer necessary. Some approaches being studied include:
- On-demand PPI use: This involves using the lowest effective dose of PPI only when symptoms occur, followed by stopping when symptoms are controlled.
- Alginate treatment: This strategy replaces PPIs with alginate formulations (like Gaviscon®) for a month before discontinuing all medication.
- Gradual dose reduction: This method involves slowly decreasing the frequency of PPI intake over a month before stopping completely.
These strategies are being evaluated to determine the most effective way to help patients reduce their reliance on long-term antacid or PPI use when appropriate.
Precautions and Considerations
While aluminium oxide, hydrated and related antacid products are generally considered safe, there are some important considerations:
- These medications are typically intended for short-term use. Long-term use should be discussed with a healthcare provider.
- Patients with certain conditions, such as severe esophagitis, peptic ulcers, or Barrett's esophagus, may require different treatment approaches.
- These medications may interact with other drugs, so it's important to inform your healthcare provider about all medications you're taking.
- Pregnant or breastfeeding women should consult their healthcare provider before using these medications.
Always consult with a healthcare professional for personalized advice on using aluminium oxide, hydrated products or any other antacid medications.
