  • Patent number: 5631023
    Abstract: The present invention discloses an improved technique for preparing a rapidly dispersing pharmaceutic tablet of a granular therapeutic agent which has both relatively low solubility and relatively large particle size. Xanthan gum is added to a liquid admixture of solvent, carrier components, and the granular therapeutic agent. The xanthan gum not only facilitates suspension of the granular therapeutic agent in the liquid admixture, but, more surprisingly, does so without adversely effecting the dispersion qualities and texture of the tablet in the patient's mouth upon administration.
