aluminum acetate  a salt prepared by the reaction of aluminum hydroxide and acetic acid; used in solution as an astringent.

basic aluminum carbonate  see under gel.

aluminum chloride  a topical astringent and anhidrotic.

aluminum chlorohydrate  the hydrate of aluminum chloride hydroxide, astringent and anhidrotic; used as an antiperspirant and as an anhidrotic in the treatment of hyperhidrosis.

aluminum hydroxide  Al(OH)3, used as an antacid, and as an adjuvant in adsorbed vaccines and toxoids; see also under gel.

aluminum oxide  Al2O3, occurring naturally as various minerals such as corundum; used in the production of abrasives, refractories, ceramics, catalysts, to strengthen dental ceramics, and in chromatography.

aluminum phosphate  an aluminum salt used as an adjuvant in adsorbed vaccines and toxoids, with calcium sulfate and sodium silicate in dental cements, and as an antacid.

aluminum subacetate  a basic acetate ester derivative used topically as an astringent.

aluminum sulfate  an astringent, used topically as a local antiperspirant; also used in the preparation of aluminum subacetate topical solution.

aluminum (Al) [ah-loo´mĭ-num]

a chemical element, atomic number 13, atomic weight 26.982. (See Appendix 6.) It occurs naturally in many foods in low concentrations and is also present in many pharmaceuticals and drinking water. High levels in the body can be toxic; see aluminum poisoning.

aluminum acetate solution Burow's solution.

basic aluminum carbonate gel an aluminum hydroxide–aluminum carbonate gel, used as an antacid, for treatment of hyperphosphatemia in renal insufficiency, and to prevent phosphate urinary calculi.

aluminum chloride a topical astringent solution and antiperspirant.

aluminum chlorohydrate an antiperspirant; called also aluminum hydroxychloride.

aluminum hydroxide the hydroxide of aluminum, used as an antacid and phosphate binder; the official preparation is aluminum hydroxide gel.

aluminum hydroxide gel a preparation of aluminum hydroxide in suspension or dried form, used as an antacid in the treatment of peptic ulcer and gastric hyperacidity and as a phosphate binder in treatment of phosphate nephrolithiasis.

aluminum hydroxychloride aluminum chlorohydrate.

aluminum oxide Al₂O₃, occurring naturally as various minerals; used in the production of abrasives, refractories, ceramics, catalysts, to strengthen dental ceramics, and in chromatography.

aluminum phosphate gel a water suspension of aluminum phosphate and some flavoring agents; used as a gastric antacid, astringent, and soothing agent.

aluminum poisoning the toxic effects of high levels of aluminum or its compounds in the body. In the gastrointestinal tract aluminum inhibits absorption of electrolytes; inhalation of aluminum fumes may cause pulmonary fibrosis; and aluminum in the bloodstream may lead to serious neurological symptoms, such as in dialysis encephalopathy.

aluminum silicate the silicate salt of aluminum, found in nature in several different hydrated forms that have pharmaceutical or dental uses; see attapulgite, fuller's earth, and kaolin.

aluminum subacetate a compound used as an astringent, diluted with water.

aluminum sulfate a compound used as an astringent solution and antiperspirant.
