Abstract
Abstract Aqueous solutions containing potassium chloride, useful for the treatment of hypokalaemia, are obtained by dissolving in water or an aqueous medium compositions comprising a mixture of a solid, water-soluble hydrochloride of a physiologically innocuous nitrogen-containing organic compound e.g. betaine hydrochloride, which dissociates an addition to water to yield an acid solution containing hydrochloric acid and the organic base, and at least one of potassium bicarbonate and potassium carbonate.
