Abstract
Abstract Aqueous solutions of alkali metal salts of salicylamide are orally administered with significantly improved analgesic, antiinflammatory, antipyretic and sedative results, as compared with solid oral dosage forms of both salicylamide and the alkali or alkaline earth metal salts of salicylamide. The solutions are formed by dissolving in water an effervescent composition comprised of a unit dosage amount of an alkali metal salt of salicylamide.
