The present invention describes the use of croscarmellose sodium to coat bitter-tasting active agents in a manner that will mask the bitter taste of these materials, taste masked pharmaceutical compositions in which the particles of pharmaceutically active agent are coated with croscarmellose sodium, taste masked pharmaceutical tablets made therefrom, in which the rapid disintegration of tablets that is imparted by croscarmellose sodium is preserved, and to a method for preparing such coated particles by preparing them in a fluidized bed coating process.

Croscarmellose taste masking

The present invention provides a method for preparing a spray-dried compressible granular formulation for preparing pharmaceutical tablets in which hydrolyzed cellulose is used as a granulation aid, the resulting granulations, and pharmaceutical tablets compressed from such granules. In these formulations there is employed from 1 to 97% by weight pharmaceutical active, from about 3 to 99% by weight hydrolyzed cellulose, based on the dry weight of the granulation, and optionally conventional granulation and/or tableting additives such as surfactants, disintegrants and antiadherents/flow aids.
