Vorschrift

Barnidipine hydrochloride, TC-5E and HCO-40 were dissolved in water-methanol (1:9). Separately, PEG20000 and POLYOX303 were mixed. Using a fluidized-bed granulator, the latter mixture was sprayed with the above solution. The granules thus prepared were dried, and after addition of lubricant, the composition was compression-molded to provide tablets each measuring 9.0 mm in diameter and 300 mg (barnidipine HCl content: 15 mg).
