PROBLEM TO BE SOLVED: To further suppress browning of 5-aminosalicylic acid or a salt thereof, or 5-aminosalicylic acid or a salt thereof even in the presence of an oxygen scavenger, and can maintain the properties of the preparation at the time of production for a long time. -It aims at providing the preservation | save system containing the amino salicylic-acid solid formulation, and its preservation | save method. The present invention relates to a 5-aminosalicylic acid solid preparation containing 5-aminosalicylic acid or a salt thereof, or 5-aminosalicylic acid or a salt thereof, using an oxygen scavenger that exhibits a deoxygenating function in a low-humidity environment. Is stored in a predetermined space by an airtight container or hermetic packaging. [Selection] Figure 1 |
