Abstract

PURPOSE:To obtain the titled composition having high dissolution rate of tritoqualine in water, by blending a compound selected from crystalline cellulose, cyclodextrin, light silicic anhydride, etc., with tritoqualine and grinding. CONSTITUTION:The titled composition containing 1pt.wt. tritoqualine shown by formula I and 1-10pts.wt. (preferably 2-9pts.wt.) one or more compounds selected from crystalline cellulose, cyclodextrin, methylated cyclodextrin, light silicic anhydride, synthetic aluminum silicate and magnesium metasilicate. The two components are blended and ground by using a vibration mill and a ball mill preferably until the ground materials are made into amorphous so that elution properties of tritoqualine are excellently improved and long-acting supersaturation phenomena can be exhibited. A dose of tritoqualine is 10-2,000mg per adult daily.
