The present invention provides a glucose decomposition-suppressed solid preparation for dialysis among powdery or granular preparations for dialysis containing acetate-free solid organic acids as pH adjusting agents. The present invention provides the solid preparation for dialysis containing electrolytes, glucose and pH adjusting agents characterized in that solid organic acids containing reduced amount of microparticles are used, and more specifically, characterized in that solid organic acids whose 20 or less percent of particles are 250 µm or less in diameter, or solid organic acids whose 10 or less percent of particles are 150 µm or less in diameter, are used. Preferably, the solid organic acid contained therein is citric acid.
