What is strychnine? Describe the actions and the uses of strychnine. 

 State the hypodermic dose of strychnine for (a) the horse, 

 (b) the dog. 



Strychnine is an alkaloid obtained from nux vomica. 



It is a nerve tonic, gastric tonic, stimulates respiration, secre- 

 tion, and digestion; it increases peristalsis, stimulates both, the 

 motor and inhibitory apparatus of the heart, and raises arterial 

 tension by stimulating the vasomotor centres, thus contracting the 

 arterioles; full doses relax the arterioles and thus reduce blood- 

 pressure. 



Used in paralysis, depression of the nervous system, atonic dys- 

 pepsia, heaves, diarrhcea due to relaxation of the bowels from lack 

 of tone, in small doses; convalescence from debilitating diseases, 

 collapse, heart-weakness, chloroform, syncope, narcotic poisoning,
