AMMONIUM CHLORIDE 141 



by acid in the stomach, but its ultimate fate is unknown. It 

 stimulates gastric secretion, vascularity and motion, and 

 also excites intestinal peristalsis. It is, therefore, a stom- 

 achic and carminative. It is also an antacid, and, in large 

 doses, an emetic to dogs. The action of ammonium carbo- 

 nate is almost identical with that of ammonia water in 

 stimulating the heart and respiration, but it has more power 

 in augmenting the bronchial secretions. 



Summary. — Cardiac and respiratory stimulant, expecto- 

 rant, stomachic and emetic. 



Administration. — Ammonium carbonate is given in ball, 

 or in solution in cold water, .to avoid irritating fumes ; also, 

 with syrup or gruel. It is often prescribed with other 

 stimulants and antispasmodics, as alcohol, capsicum, cam- 

 phor and asafoetida. 



Uses. — The indications for the administration of ammo- 

 nium carbonate are much the same as those for ammonia 

 preparations. It is a more useful expectorant, however, and 

 it and the aromatic spirit are more serviceable in the treat- 

 ment of flatulence. For the latter condition in horses with 

 colic a ball containing ammonium carbonate 3 ii-, and cap- 

 sicum 3 i., with sufficient linseed meal and molasses to make 

 the proper bulk and consistency, is often efficient. We may 

 use ammonium carbonate alone in the case of acute or 

 chronic bronchitis, or it may be combined with other stim- 

 ulants, or expectorants, as a-mmonium chloride.
