SUPPOSITORIA. 



Suppositories are conical, cylindrical, or spheroidal preparations made by com- 

 bining medicinal substances with some other substance, like glycerinated gelatin or 

 cacao butter, that melts but slowly at body temperatures. They are used to favor pro- 

 longed application of medicines to the walls of the various body cavities. 



Make the official Suppositoria Glycerini as follows : Dissolve 0.05 Gm. monohy- 

 drated sodium carbonate in 0.5 mil water ; add 2.7 mil glycerin and 0.2 Gm. stearic 

 acid; cover, and heat the mixture over a water bath until all the COo has been driven 

 off and the liquid is clear (15 minutes or more). Then pour the material into a suit- 

 able mold (a small conical graduate will do) ; cool in flowing water, and, when it is 

 firm, remove from the mold and examine.
