Abstract

The invention provides a granular product useful as a pharmaceutical carrier which can be used for the preparation of pharmaceutical compositions that are capable of rapid suspension in water or aqueous media including saliva. The compositions may be used by addition to a glass of water with stirring or taken directly in the mouth. The granular product may be prepared by a process which comprises subjecting a mixture of a thickening agent and a disintegrating agent to wet granulation with an aqueous medium as wetting agent or dry granulation and preparing the pharmaceutical composition from the granular product and the pharmaceutically active ingredient. A water-soluble inert excipient, which may be a sugar, may be mixed with the granular product prior to mixing with the pharmaceutically active ingredient.
