464 GERMICIDES — DISINFECTANTS 



POTASSn PERMANGANAS — POTASSIUM 

 PERMANGANATE 



Potassium permanganate occurs as slender dark prisms, odorless 

 and of a sweetish astringent taste, soluble in 15 parts of water, 

 decomposed by alcohol. 



Incompatibles. It is incompatible with almost everything. 

 It forms explosives with oxidizable substances, especially organic 

 matter as alcohol or glycerin. 



Doses. H. 3 ss — ^j ; 2. — 4. In pill or drench after meals, 

 D. gr. ss— j ; 0.03—0.065. 



Action. If used in pure form or in concentration it is a mild 

 irritant and caustic. If administered in excessive doses it causes 

 all the symptoms of corrosive poisoning. It gives up oxygen in the 

 presence of organic matter and consequently is a germicide and 

 deodorant. Its usefulness, however, is somewhat lessened by its 

 rapid deoxidation which leaves it inert. 



Uses. 1. As a Deodorant and Antiseptic. In such conditions 

 as stomatitis, fetid ulcers, metritis, etc. in 1 to 2 per cent, solution. 



2. Antiseptic for the Hands. Use a saturated solution and re- 

 move the stain with hydrogen peroxide or oxalic acid. 



3. Poisoning hy Morphine or Other Alkaloids. Potassium 

 permanganate is the chemical antidote for the alkaloids and is gener- 

 ally used in dilute solutions to wash out the stomach. There are 

 no other indications for tlie internal use of the drug. 



* Acetozone. (Acetyl — • Benzoyl — Peroxide) occurs as a 

 white crystalline powder soluble in 1000 parts of water, in 20 parts 

 of oil, slightly soluble in alcohol, fairly so in ether and chloro- 

 form, but slowly decomposing in all of these solvents with the ex- 

 ception of petroleum oil. It also decomposes on contact with or- 

 ganic matter and alkalies. It is marketed only in a 50 per cent, 

 mixture with an inert powder. It evolves hydrogen dioxide in the 

 presence of water. It is usually employed in a solution of 20 to 30 

 grains to a quart of water, and this may be given in doses of 2 to 5 

 ounces every few hours to a dog as an intestinal or gastric anti- 

 septic. It may be useful in treating purulent conjunctivitis or 

 keratitis in strengths of 5 grains to the pint of water, or may be 

 employed as a dusting powder, 10 per cent, with boric acid, talcum, 

 zinc oxide, etc. 



SODII PERBORAS — SODIUM PERBORATE 



This occurs as a white, granular salt, odorless, having a saline 

 taste, soluble in water, and evolves hydrogen peroxide in aqueous 

 solutions. It should contain at least 9 per cent, of available oxygen. 



* Unofficial.
