dilute acids, decomposes slowly in the intestines, so that it has the 

 antiseptic action of urotropin and the astringent action of tannin. 

 Dose same as for nrotropin. 



* Tannoform. This is a similar compound of tannin and 

 formaldehyde. It resembles the action of the preceding drug but 

 is more irritant. According to Frohner it is the most efficient desic- 

 cant antiseptic for new or old wounds. Used alone or with starch.

* CHINOSOL 



Oxyquinolin Sulphate — JSTormal Oxyquinilin Sulphate 



Chinosol is a yellow crystalline powder, of saffron-like odor and 

 burning taste, is readily soluble in water, slightly soluble in alcohol, 

 insoluble in ether. 



Action and Uses. Chinosol is said to be nontoxic. It is 

 somewhat more powerful as an antiseptic than corrosive sublimate or 

 phenol, having been found to exert an antiseptic action in 1 — 10,000 

 solutions. On the other hand it is a weaker germicide or disinfectant 

 than phenol or corrosive sublimate. It does not form compounds 

 with the tissues or injure mucous membranes or tissues, but is in- 

 compatible with alkalies and salts of mercury and iron. It is claimed 

 not to cause harmful irritation in any strength, to possess analgesic 

 properties and to be a deodorant. It is used particularly as an anti- 

 septic for mucous membranes starting with solutions as weak as 

 1 : 1000 or 2000 and increasing gradually to 1 : 500 if the patient 

 will tolerate it. The usual strength recommended is 1 : 1000. Much 

 stronger solutions may be employed as a wound dressing. Hobday 

 says that it is somewhat toxic for the cat either from administration 

 per OS or from applications to the skin, but that it is not rapidly ab- 

 sorbed from the intact skin of the dog.
