Action of Ammonium Chloride

Locally applied, ammonium chloride increases the secretion of mucous membranes, and to a slight extent it does the same after absorption. It is a feeble cholagogue, diaphoretic, diuretic, and a general stimulant, but of less power than the carbonate.

Therapeutics of Ammonium Chloride

It is a very favorite remedy for local application, by means of inhalation of the vapor, to increase the secretion of mucus from the pharynx, Eustachian tubes, larynx, trachea and bronchi in cases of chronic pharyngitis, otitis media, laryngitis, and bronchitis. Many forms of apparatus for its inhalation are in the market. In most of them it is generated by the action of hydrochloric acid on ammonia. It is occasionally given by the mouth, either as a cholagogue, gastric stimulant, diaphoretic, or diuretic, but it is too feeble to be recommended, and it is very unpleasant; the taste may to some extent be concealed by liquorice. It is useful in chronic bronchitis with much expectoration and is then best given as a troche or compressed tablet with chocolate. Some authorities consider it to be, in large doses, a specific for neuralgia.
