aluminum carbonate, basic

a·lu·mi·num car·bon·ate, ba·sic

an aluminum hydroxide-carbonate complex consisting of white lumps, insoluble in water; aqueous suspensions bind phosphorus in the intestine and lower serum inorganic phosphorus resulting in an increase in reabsorption of phosphorus by renal tubules and reduction of urinary excretion of phosphorus; it reduces formation of phosphatic urinary calculi and gastric acidity.
