Description
Aluminum hydroxide is an inorganic salt used as an antacid. It is a basic compound that acts by neutralizing hydrochloric acid in gastric secretions. Subsequent increases in pH may inhibit the action of pepsin. An increase in bicarbonate ions and prostaglandins may also confer cytoprotective effects.
Indication
For relief of heartburn and acid indigestion.
Mechanism of Action
Aluminum hydroxide is a basic inorganic salt that acts by neutralizing hydrochloric acid in gastric secretions. Aluminum hydroxide is slowly solubilized in the stomach and reacts with hydrochloric acid to form aluminum chloride and water. It also inhibits the action of pepsin by increasing the pH and via adsorption. Cytoprotective effects may occur through increases in bicarbonate ion (HCO3-) and prostaglandins.
Pharmacokinetics
- Absorption
- Approximately 17-30% of the aluminum chloride formed is absorbed.
- Distribution
- Metabolism
- Not metabolized.
- Elimination

Description
Magnesium trisilicate is an inorganic compound that is used as an antacid in the treatment of peptic ulcers.
Indication
For the treatment of peptic ulcers. Relieving indigestion and heartburn.
Mechanism of Action
The gelatinous silicon dioxide, formed by the reaction of magnesium trisilicate with gastric contents is said to protect ulcerated mucosal surfaces and favor healing.
Pharmacokinetics
- Absorption
- The hydrated silicon dioxide formed in the stomach and passes into the intestinal track where, silica can be partly absorbed.
- Distribution
- The hydrated silicon dioxide formed in the stomach and passes into the intestinal track.
- Metabolism
- Elimination
Clearance
Maximum magnesium clearance is directly proportional to creatinine clearance.
Toxicity
Adequate doses of magnesium trisilicate may cause diarrhea due to the action of soluble magnesium salts in the enteric tract. Approx 5% of the magnesium is absorbed.

Description
Simethicone is an orally administered antifoaming agent. It is mainly used to reduce gas from the gastrointestinal tract (GIT) in patients complaining from recurrent flatulence. Simethicone is a mixture of polydimethylsiloxane and hydrated silica gel. It exerts its action locally in the GIT, it is not absorbed into the blood stream. The main side effects of simethicone are GIT related including: mild diarrhea, nausea and vomiting.
Indication
1. To relieve pain and discomfort caused by excess gas in the intestine and stomach in cases such as flatulence and post operative gaseous distention. 2. It could be used also prior to an endoscopy to eliminate foam, gas and air from the gastrointestinal tract to reduce gas shadow which will result in better visualization.
Mechanism of Action
Decreases the surface tension of gas bubbles thereby disperses and prevents gas pockets in the GI system.
Pharmacokinetics
- Absorption
- Not absorbed following oral administration.
- Distribution
- Simethicone is pharmacologically inert and is not absorbed from the gastrointestinal tract.
- Metabolism
- The drug is not absorbed and it is excreted in the feces unchanged.
- Elimination
Clearance
Excreted unchanged in feces.
Toxicity
LD50 (oral, rat): 4070 mg/Kg.
