    • PROBLEM TO BE SOLVED: To provide an aqueous solution preparation comprising an antibody and having a pH of 6.00-7.00, particularly an aqueous solution preparation keeping the antibody stable even after long-term preservation.
      SOLUTION: The aqueous solution preparation comprises a buffering agent, a surfactant, an antioxidant, an isotonic agent and an antibody and has a pH of 6.00-7.00. The surfactant is preferably a polysorbate, more preferably polysorbate 80. The antioxidant is preferably methionine. The isotonic agent is preferably sugar or sorbitol. The concentration of the buffering agent is preferably 10-20 mM. The surfactant is preferably polysorbate 80 in a concentration of 0.5-1.0 mg/mL. The concentration of methionine as the antioxidant is preferably 10-15 mM.
