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.本發明提供一種抑制葡萄糖分解作用之透析用固態製劑,其介於透析用粉狀或粒狀製劑間,且含有無乙酸鹽的固態有機酸作為pH調整劑。本發明提供一種含有電解質、葡萄糖和pH調整劑之透析用固態製劑,其特徵在於使用含有減低量之微粒的固態有機酸,更特別地,其特徵在於使用其20%或更少的粒子之直徑為250微米或更小之固態有機酸,或其10%或更少的粒子之直徑為150微米或更小之固態有機酸。較佳地,此固態有機酸中含有檸檬酸。
