MATERIA MEDICA AND THERAPEUTICS. 1^9 



Dose. — Horse, l / 2 to I oz. ; dogs, 2 to 20 grs. Good drug 

 in rheumatism of dogs. 



ammonii bromidum. — Occurs in colorless, prismatic crys- 

 tals, soluble in iy 2 of water, and in 30 of alcohol. It resembles 

 the potassium salt in action, except that it exerts less influence on 

 the heart and muscular system, and is somewhat more stimulat- 

 ing. It irritates the stomach. 



Dose the same as Bromide of Lithium. 



calcii bromidum — Calcium Bromide. Same dose as the 

 bromide of soda and potash. 



strontii bromidum — Strontium Bromide, dose about % 

 that of potassium bromide. 



zinci bromidum — Zinc Bromide, is a violent irritant in 

 large doses ; used in epileptic conditions. Dose, dogs, grs. J4 to 2. 

 to 2. 



acidum hydrobromicum dieutum. — Contains 10 per cent 

 absolute hydrobromic acid ; used as a substitute for the bromides. 



Dose. — Dogs, 5 ms. to 2 drs., well diluted. 



For Cerebral engorgement in dogs : 



5 Ac. hydrobrom dil., 3 vj. — 3 J- 



. Fl. Ex., ergot, 3 j. 



Syr. aurantii cortex, qs. ad.,3 iv. 

 M. Sig. — One drachm 4 or 5 times daily in water. 



Antagonists and Incompatibles. — Acids, acidulous and metal- 

 lic salts are incompatible with bromides of ammon. and potash, 

 and nitrous ether with the former ; physiological actions are an- 

 tagonized by cold, digitalis, belladonna, ergot and other agents 

 which energize the vaso-motor nervous system. 



Synergists. — Opium, chloral and other remedies of this 

 group, promote the actions of the bromides on the brain, and 

 aconite, veratrum viride, gelsemium, etc., increase the depressing 

 effects of them on the circulatory system. 



Physiological Actions. — They are pre-eminently depressants 

 of the cerebral and spinal functions, also alterative, antispasmodic, 

 hypnotic, and anaphrodisiac. The bromide of potash like all 

 other potassium salts is especially a cardiac and muscular par- 

 alyzant, they are very diffusible and slowly eliminated ; long con- 

 tinued doses produce gastric catarrh ; they reduce the number of 

 respirations and the heart's action and force ; lessen activity of
