A volatile and pungent ammoniacal salt, produced by submitting a mixture of sulphate or chloride of ammonium and carbonate of calcium to sublimation. It consists of a mixture of acid carbonate of ammonium (NH4HCO3), and carbamate of ammonium (NH4NH2CO2).
Characters. - In translucent crystalline masses, with a strong ammoniacal odour, and alkaline reaction.
Solubility. - Soluble in cold water, more sparingly in spirit. Reactions. - It volatilises entirely when heated, and is readily dissolved by acids with effervescence.
20 grains of Carbonate of Ammonium neutralise
Preparations in which Carbonate of Ammonium is used.
Spiritus Ammoniae Aromaticus.
Uses. - Carbonate of ammonium may be used as an inhalation, and may be given internally, for similar purposes to liquor aminoniae.
It is an emetic, and may be employed in cases of bronchitis, where the bronchial tubes are choked with mucus, and the patient's circulation is weak. In smaller doses it stimulates the secretion of gastric juice, and may be used in atonic dyspepsia, flatulence, and colic to relieve sinking and depression, and as a substitute for alcoholic stimulants. When employed for this latter purpose, five to ten grains may be given along with ten minims of tincture of capsicum in an ounce of bitter infusion, to be taken whenever the feeling of sinking comes on, or the craving for alcoholic stimulants is experienced.
From its power of stimulating the respiratory centre, it is employed as a stimulating expectorant in chronic bronchitis, in the broncho-pneumonia of children, and in asthma depending on cardiac disease. It is also given in measles, and has been recommended as almost a specific in scarlet fever, in doses of three to five grains, every one, two, or three hours, according to the severity of the case, no acid drinks or fruits being allowed to the patient at the time.
Carbonate of ammonium has been supposed to have the power of preventing iodism, when given along with iodide of potassium.
