Abstract
A pharmaceutical composition suitable for preparing an extemporaneous suspension, that promptly releases active agents or ingredients (drugs) is disclosed. These compositions comprise an active agent in microgranule form. The microgranules containing the active agent are coated with a film coating mixture containing at least one lipid material and an optional hydrophilic additive. The coating envelopes the microgranules but does not impart a controlled release property to the composition, and affords prompt release thereof once ingested.
