GLYCYRRHIZIN HIGH-CONCENTRATION PREPARATION

摘要

[PROBLEMS] To provide a glycyrrhizin/aminoacetic acid/cysteine combination drug containing an active ingredient in high concentration and excelling in stability and safety. [MEANS FOR SOLVING PROBLEMS] Stability at compounding of active ingredient in high concentration has been improved by avoiding the addition of sulfite salts having been used as a stabilizer in existing products. As glycyrrhizin high-concentration preparations, there is provided a drug composition comprising 8 to 16 mg/mL of glycyrrhizin, 3 to 6 mg/mL of cysteine and 80 to 160 mg/mL of aminoacetic acid wherein no sulfite salts are added as an additive.
