Pharmacology

Indication:	For relief of heartburn and acid indigestion.
Pharmacology:	Gastric-peptic disease occurs as a result of an imbalance between protective factors, such as mucus, bicarbonate, and prostaglandin secretion, and aggressive factors, such as hydrochloric acid, pepsin, and Helicobacter pylori (H. pylori). Antacids work by restoring acid-base balance, attenuating the pepsin activity and increasing bicarbonate and pr... show more » Gastric-peptic disease occurs as a result of an imbalance between protective factors, such as mucus, bicarbonate, and prostaglandin secretion, and aggressive factors, such as hydrochloric acid, pepsin, and Helicobacter pylori (H. pylori).

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.

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. show less «
Absorption:	Approximately 17-30% of the aluminum chloride formed is absorbed.
Biotransformation:	Not metabolized.
Route of elimination:	Absorbed aluminum chloride is rapidly eliminated by the kidneys in patients with normal renal function.

Interactions

Drug interaction:

Cholecalciferol

Vitamin D analogs such as cholecalciferol may increase the serum concentration of aluminum hydroxide. Specifically, the absorption of aluminum may be increased, leading to increased serum aluminum concentrations. Avoid chronic and/or excessive use of aluminum and aluminum-containing products in patients who are also taking vitamin D analogs. Any patients consuming such a combination should be monitored closely for aluminum status and signs/symptoms of aluminum-related toxicities.

Calcipotriol

Vitamin D Analogs may increase the serum concentration of Aluminum Hydroxide. Specifically, the absorption of aluminum may be increased, leading to increased serum aluminum concentrations. Avoid chronic and/or excessive use of aluminum and aluminum-containing products in patients who are also taking vitamin D analogs. Any patients consuming such a combination should be monitored closely for aluminum status and signs/symptoms of aluminum-related toxicities.
