Abstract
The present invention concerns a novel pharmaceutical preparation having a biphasic release pattern. The preparation comprises a tablet core containing a drug. The tablet is coated with a coating essentially consisting of a film-forming water-insoluble polymer having fine water soluble particles randomly distributed therein. The fine particles include a drug active substance, which is the same as the drug in the core. The drug active substance in the particles may also be different from the one in the tablet core.
