摘要:
Disclosed are a clear aqueous solution of diclofenac sodium dissolved in a mixed solvent of a fatty acid dialkylolamide and water; an anti-inflammatory analgesic composition excellent in percutaneous absorption, which comprises the clear aqueous solution and a higher unsaturated aliphatic alcohol contained in the solution; and a self-adhesive cataplasm comprising a cataplasm base and the clear aqueous solution, polybutene and gelatin added in the base. The clear aqueous solution of diclofenac sodium contains, in particular, diclofenac sodium, a fatty acid alkylolamide and water at a ratio falling within a hexagonal region formed by linking the points A, B, C, D, E and F in the figure.
