ABSTRACT:
A sustained-release multi-granule tablet is obtained by compressing sustained-release granules, which contains a basis, and a formulation adjuvant. Each of the granules has been coated in advance with a layer of the formulation adjuvant and/or a layer of a mixture of the formulation adjuvant and the basis. The tablet releases an active substance at a suitable velocity into the digestion tract, resulting in that the inbalance in the absorption of the drug in each patient and among individual patients is minimized to achieve maximum bioavailability.
