Sounds almost like antacid. Magnesium aluminum hydroxide should have less bounce back effect. 

Maalox = magnesium and aluminum hydroxides.

no such thing as the hydroxide. adding Na+ to Al hydroxide gives only oxide mentioned. did you mean hydride?! that is a different story and not something you'd want to take as an antacid. this is much like LAH but with THF or dimethyl Cellosolve as solvent as it has low et2o sol. find out which you have by tossing a chunk in a distant pail of H20.
