PREPARATION FOR SUSTAINED RELEASE OF DICLOFENAC SODIUM

摘要

PROBLEM TO BE SOLVED: To obtain a preparation of diclofenac sodium, easily produced, and excellent in sustained release of diclofenac sodium and in its preservation stability. ;SOLUTION: This preparation for sustained release of diclofenac sodium is obtained by coating a core granule containing diclofenac sodium and phosphoric acid or its salt as the acidic component with a film for sustained release, which is made of a mixture of a hydroxypropylmethyl cellulose acetate and aminoalkyl methacrylate-based copolymer in a weight ratio of (3:7) to (8:2).;COPYRIGHT: (C)1999,JPO
