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.

Prompt-release oral pharmaceutical compositions for extemporaneous suspensions

Disclosed is a controlled release pharmaceutical dosage form, including: (a) microgranules of a pharmaceutical and an excipient; (b) a plurality of polymeric lipidic and wax-like coatings applied to the microgranules, the coated microgranules having dimensions which allow suspension of the coated microgranules in a liquid administration vehicle; and (c) a liquid administration vehicle for the coated microgranules, the vehicle including an effective amount of the pharmaceutical in a form immediately available upon ingestion. A process for the preparation of the controlled release therapeutic system is also described.

Controlled release therapeutic system for liquid pharmaceutical

The object of the invention is a process for the preparation of microgranules to be used in controlled-release liquid pharmaceutical compositions. Operating with high-shear mixer-granulators within clearly established crucial parameter ranges, this process results in microgranules having a particle size distribution, a density, a surface and a shape which make them particularly suitable for coating and then suspension in fluids.
