<p>A process is provided for efficiently producing sustained-release tablets having superior sustained-release properties capable of inhibiting the initial elution of a drug and allowing the drug to be completely eluted after a prescribed amount of time has elapsed. A process for producing sustained-release tablets comprising: dry granulating a mixture composed of a hydroxyalkyl cellulose (A) having a viscosity of 1 to 50 mPa · s in a 2% by mass aqueous solution at 20°C, a Hydroxyalkyl cellulose (B) having a viscosity of 100 mPa · s or more in a 2% by mass aqueous solution at 20°C, an active ingredient and an additive, and forming the resulting granules into tablets.</p> |
