Abstract: Compositions are provided for the preparation of stable sodium aspirin tablets. The compositions comprise dry, crystalline sodium aspirin, an anhydrous binder that is unreactive to sodium aspirin and a hydrogenated animal or vegetable oil lubricant but lack the traditional tablet disintegrant. Tablets produced from these compositions can be stored for prolonged periods of time yet disintegrate in water at a rate comparable to that of ordinary aspirin.
