Tabellae — Tablets. 



Tablets are small disc-shaped bodies containing medicinal 

 agents. With the exception of Toxitabellae Hydrargyri Chloridi 

 Corrodvi they are unofficial but nevertheless largely employed. 

 There are several varieties ; tablet triturates, compressed tablets, 

 coated tablets, hypodermic tablets and dispensing tablets. 



Tablet triturates are prepared by triturating the medicament 

 with finely powdered sugar of milk if powerful agents are used, or 

 if the substance requires no dilution, triturating it to a very fine 

 powder, moistening the powder with sufficient alcohol or other vola- 

 tile substance to make a paste. The moistened powder is then 

 pressed into molds consisting of a plate perforated with holes and 

 then pressing out the tablets by fitting this perforated plate over 

 another plate upon which are stituated pegs that accurately fit the 

 perforations. The liquid is evaporated very quickly, after which 

 the tablets retain their shape and are ready for use. They possess 

 advantages over any other method of administering solids in 

 human and small animal animal practice as they are more conven- 

 iently administered than powders and are more soluble than pills, 

 compressed tablets or capsules. Well made triturates disintegrate 

 almost immediately on being placed in water. 



Hypodermic tablets are made by the same process. The selec- 

 tion of the diluent is an important question because rapid solu- 

 bility is desired. Dried neutral sodium sulphate has been largely 

 employed and frequently they contain in addition some substance 

 which produces chemical change when added to water and causes a 

 rapid disintegration of the mass.
