ammonium

 [ah-mo´ne-um]
a hypothetical radical, NH4, forming salts analogous to those of the alkaline metals.
ammonium carbonate a mixture of ammonium compounds used as a liquefying expectorant in the treatment of chronic bronchitis and similar lung disorders. It is sometimes used as a reflex stimulant in “smelling salts” because of the strong ammonia odor it gives off.
ammonium chloride colorless or white crystals, with a cool, salty taste, used as an expectorant because it liquefies bronchial secretions. In the body it is changed to urea and hydrochloric acid, and thus is useful in acidifying the urine and increasing the rate of urine flow. Excessive dosage may produce acidosis.
ammonium lactate lactic acid neutralized with ammonium hydroxide, applied topically in the treatment of ichthyosis vulgaris and xerosis.
