CERATA — CERATES 



These are preparations of medicinal substances with fats and 

 waxes of such a consistency as to be soft enough to spread upon muslin 

 or other material and not soft enough to liquefy when applied to the 

 skin. They are called Cerates because they contain wax or cera. 

 They may be prepared by fusion or incorporation but all the official 

 ones are directed to be made by the former method. Three are 

 official : 



Ceratum Cerate. Used only as a base 



Ceratum Eesina? Eesin or Eosin Cerate

SUPPOSITORIA — SUPPOSITORIES 



Suppositories are solid bodies of various shapes and weights, 

 adapted for the introduction into various orifices of the body, and 

 melting or softening at body temperature. The vehicles usually 

 employed are oil of theobroma, glycerinated gelatin and sodium 

 stearate. The ideal suppository consists of a medicine blended with 

 some inert base which will not liquefy at ordinary temperatures but 

 will melt at the body temperature. They may be prepared by three 

 processes, rolling, molding and compression. The first method con- 

 sists of making a mass, rolling it into a cylinder, cutting the cylin- 

 der and shaping with the hands. In case of those made by molds, 

 the mass is liquefied and poured into thoroughly chilled molds. By 

 compression the medical substance is mixed with finely grated oil 

 of theobroma and compressed with a lever. 



There is one official suppository — Suppositoria Glycerini, be- 

 sides which the Phannacopceia contains general formulas for those 

 made with oil of theobroma and glycerinated gelatin.
