Direct compression polymer tablet core

The invention claims a at least about 95% weight ratios aliphatic polymer containing tablet nucleus. The invention claims further claims a preparation comprising at least about 95% weight ratios aliphatic polymer containing resin the method of tablet nucleus. Method for preparing to tablet nucleus comprising a pressurizing aliphatic polymer containing a step. The tablet nucleus of the further - comprising a or multiple types of excipients. The preferred embodiment, which the tablet nucleus the method comprises the steps: (1) Hydration or the dry aliphatic polymer containing a horizontal at the moisture for steps; (2) Accounts of the product admixture at least 95% weight ratios of the polymer the aliphatic polymer containing a right and excipients; andAnd (3) multivalent admixture of tablet nucleus. The invention further claims at least about 95% weight ratios aliphatic polymer containing coating nucleus tablet, the coating is water is coated.
