PURPOSE:To produce the titled composition having high physical stability, by uniformly dispersing aluminum hydroxide gel and a specific cellulose derivative in water at specific ratios. CONSTITUTION:The objective aluminum hydroxide gel composition can be produced by uniformly dispersing 0.5-8.0wt% aluminum hydroxide gel (in terms of aluminum oxide) and 0.3-8.0wt% cellulose derivative having hydroxyalkoxy group (e.g. hydroxypropyl methyl cellulose) as a stabilizer in water. The aluminum hydroxide gel is e.g. an aqueous suspension or its dried powder produced by dissolving a proper amount of an aluminum salt such as aluminum sulfate in purified water, dripping excess sodium carbonate or other carbonate solution thereto to form a precipitate, vigorously shaking the product to obtain a mixture and dialyzing the mixture. The composition can be used as a drug for external or internal use and may contain other drug-active component.
