First claim

Opening claim text (preview).

The invention claimed is: 1. A liquid composition comprising a compound of formula (1) or a salt thereof: a water-soluble additive, and water, wherein the water-soluble additive is at least one selected from the group consisting of polyoxyethylene hydroxy fatty acid ester, poloxamer, polyoxyethylene castor oil, polyoxyethylene hardened castor oil, hydroxypropyl-β-cyclodextrin, methyl-β-cyclodextrin, hydroxypropyl-α-cyclodextrin, sulfobutyl ether-β-cyclodextrin, cysteine, sodium sulfite and sodium azide, wherein, after storage at 40° C. for 2 weeks, a residual rate of the compound of formula (1) or a salt thereof in the composition is 90% or more by mass, wherein the content of the compound of formula (1) or a salt thereof in the composition is 0.01 to 1 w/v %, and wherein a mass ratio of the compound of formula (1) or a salt thereof to the water-soluble additive [compound of formula (1) or salt thereof:water-soluble additive] is 1:0.02 to 1:1,300. 2. The composition according to claim 1 , wherein the pH is 4 to 10. 3. The composition according to claim 1 , wherein the composition is an aqueous solution, and the aqueous solution does not contain a precipitate after storage at 40° C. for 2 weeks. 4. A product comprising the composition according to claim 1 filled in a vial or a syringe. 5. The composition according to claim 1 , wherein a decomposition product from the compound of formula (1) or a salt thereof is at least one selected from compounds of formulas (2) to (4): wherein R is an optionally substituted amino group or an optionally substituted alkoxy group. 6. A method for inhibiting decomposition of the compound of formula (1) or a salt thereof according to claim 1 , the method comprising making a water-soluble additive and the compound of formula (1) or a salt thereof coexist in a liquid composition containing water, wherein the water-soluble additive is at least one selected from the group consisting of polyoxyethylene hydroxy fatty acid ester, poloxamer, polyoxyethylene castor oil, polyoxyethylene hardened castor oil, hydroxypropyl-β-cyclodextrin, methyl-β-cyclodextrin, hydroxypropyl-α-cyclodextrin, sulfobutyl ether-β-cyclodextrin, cysteine, sodium sulfite and sodium azide, wherein the content of the compound of formula (1) or a salt thereof in the composition is 0.01 to 1 w/v %, and wherein a mass ratio of the compound of formula (1) or a salt thereof to the water-soluble additive [compound of formula (1) or salt thereof:water-soluble additive] is 1:0.02 to 1:1,300. 7. A method for stabilizing a liquid composition, the method comprising making coexist a water-soluble additive, the compound of formula (1) or a salt thereof according to claim 1 and water in the liquid composition, wherein the water-soluble additive is at least one selected from the group consisting of polyoxyethylene hydroxy fatty acid ester, poloxamer, polyoxyethylene castor oil, polyoxyethylene hardened castor oil, hydroxypropyl-β-cyclodextrin, methyl-β-cyclodextrin, hydroxypropyl-α-cyclodextrin, sulfobutyl ether-β-cyclodextrin, cysteine, sodium sulfite and sodium azide, wherein the content of the compound of formula (1) or a salt thereof in the composition is 0.01 to 1 w/v %, and wherein a mass ratio of the compound of formula (1) or a salt thereof to the water-soluble additive [compound of formula (1) or salt thereof:water-soluble additive] is 1:0.02 to 1:1,300.
