Pharmaceutical composition

2-10. (canceled)

A pharmaceutical composition, comprising a compound represented by the following formula (1) and a component (A):

• the component (A):
• at least one type of compound selected from the group consisting of a nonionic surfactant, a hydroxyalkylated cyclodextrin, a C1 to C3 mono-alcohol, a C2 to C3 di-alcohol, a C3 to C6 tri-alcohol, a polyalkylene glycol, a γ-lactone, polyvinylpyrrolidone, a chlorogenic acid, and an alkyl sulfate ester, and salts thereof:
• wherein a is 0.01 or more and 0.7 or less, a+b is 1, n is an integer of 25 or more and 25,000 or less, respective constituent disaccharide units may be arranged in a random or block form, and R is each independently a carboxy group or a carboxylate salt group in the respective constituent disaccharide unit.

An aqueous composition, comprising a compound represented by the following formula (1) and a component that suppresses the accumulation and/or generation of a diclofenac component,

• wherein a relative amount of diclofenac lactam after storage in a thermostat bath at 60° C. for 1 week is 0.9 or less, provided that the relative amount is a value when an aqueous composition (control composition) which is the same except that the component that suppresses the accumulation and/or generation of a diclofenac component is not contained is stored under the same conditions and the amount of diclofenac lactam accumulated in the control composition is assumed to be 1:
• wherein a is 0.01 or more and 0.7 or less, a+b is 1, n is an integer of 25 or more and 25,000 or less, respective constituent disaccharide units may be arranged in a random or block form, and R is each independently a carboxy group or a carboxylate salt group in the respective constituent disaccharide unit.
