Abstract
A hard capsule for pharmaceutical drugs comprises a water-soluble cellulose derivative as a capsule base, a gelatinizing agent and an auxiliary for gelation. The hard capsule is prepared by preparing an aqueous solution of a capsule base containing a water-soluble cellulose derivative, a gelatinizing agent and an auxiliary for gelation, immersing a capsule molding pin in the aqueous solution of the capsule base, subsequently drawing out the molding pin from the aqueous solution of the capsule base, subjecting the aqueous solution of the capsule base attached to the outer surface of the molding pin to gelate at room temperature, and forming a capsule film on the outer surface of the molding pin.
