Description

本発明は、酸化チタンを含有する合成樹脂製容器または紫外線遮断性フィルムで密着包装した容器に、キノロン系抗菌化合物またはその塩を含有する水性液剤を保存することにより、水性液剤中の該キノロン系抗菌化合物の含有率の低下を抑制したキノロン系抗菌化合物含有製品に関する。   The present invention relates to a quinolone compound in an aqueous solution by storing an aqueous solution containing a quinolone antibacterial compound or a salt thereof in a container made of a synthetic resin containing titanium oxide or a container closely packed with an ultraviolet blocking film. The present invention relates to a quinolone antibacterial compound-containing product that suppresses a decrease in the content of the antibacterial compound.

キノロン系抗菌化合物は、強い抗菌力を示し、安全性にも優れている。例えば、(−)−(S)−9−フルオロ−2,3−ジヒドロ−3−メチル−10−(4−メチル−1−ピペラジニル)−7−オキソ−7H−ピリド[1,2,3−de]−1,4−ベンゾキサジン−6−カルボン酸(レボフロキサシン)や9−ジヒドロ−3−メチル−10−(4−メチル−1−ピペラジニル)−7−オフルオロ−2,3−キソ−7H−ピリド[1,2,3−de]−1,4−ベンゾキサジン−6−カルボン酸(オフロキサシン)などのキノロン系抗菌化合物は、点眼剤などの医薬品に汎用されている。   Quinolone antibacterial compounds exhibit strong antibacterial activity and are excellent in safety. For example, (−)-(S) -9-fluoro-2,3-dihydro-3-methyl-10- (4-methyl-1-piperazinyl) -7-oxo-7H-pyrido [1,2,3- de] -1,4-benzoxazine-6-carboxylic acid (levofloxacin) and 9-dihydro-3-methyl-10- (4-methyl-1-piperazinyl) -7-ofluoro-2,3-xo-7H-pyrido Quinolone antibacterial compounds such as [1,2,3-de] -1,4-benzoxazine-6-carboxylic acid (ofloxacin) are widely used in pharmaceuticals such as eye drops.

一方、点眼容器に関しては、外部より内容物を透視できることが要望されるので、容器の光透過性を維持すると共に、容器中の薬物を長期に渡って安定に保存できることが望ましい。   On the other hand, regarding an eye drop container, since it is desired that the contents can be seen through from the outside, it is desirable to maintain the light transmittance of the container and to stably store the drug in the container for a long period of time.

しかし、上記キノロン系抗菌化合物を含有する水性液剤を光透過性の容器に保存すると、光に晒される環境下では経時的にキノロン系抗菌化合物の含有率が低下することが知られている。   However, it is known that when the aqueous liquid preparation containing the quinolone antibacterial compound is stored in a light-transmitting container, the content of the quinolone antibacterial compound decreases with time in an environment exposed to light.

特許文献1は、紫外線透過を防止する合成樹脂組成物に係る発明を記載し、合成樹脂に平均粒子径が30〜40nmの微粒子チタンを配合すれば、紫外線の透過性を抑制できることが述べられ、また、特許文献2は、紫外線吸収性樹脂組成物に係る発明を記載し、合成樹脂に特定の重量配合比の超微粒子金属酸化物およびベンゾトリアゾール系有機化合物を配合すれば、紫外線透過を抑制できることが述べられている。   Patent Document 1 describes an invention relating to a synthetic resin composition that prevents ultraviolet light transmission, and it is stated that if fine titanium particles having an average particle diameter of 30 to 40 nm are blended with a synthetic resin, ultraviolet light transmission can be suppressed, Patent Document 2 describes an invention relating to an ultraviolet-absorbing resin composition, and if an ultrafine metal oxide and a benzotriazole-based organic compound having a specific weight blending ratio are blended with a synthetic resin, ultraviolet transmission can be suppressed. Is stated.

これらの先行文献はいずれも紫外線の透過性を抑制する技術を記載したものであるが、キノロン系抗菌化合物を含有する水性液剤を容器に保存する上で、キノロン系抗菌化合物の含有率の低下を抑制することを示唆するような記載は全くない。

Each of these prior documents describes a technique for suppressing ultraviolet light transmittance, but when storing an aqueous liquid preparation containing a quinolone antibacterial compound in a container, the content of the quinolone antibacterial compound is reduced. There is no description that suggests suppression.
JP 50-158630 A JP 2004-182984 A

上記したようにキノロン系抗菌化合物を含有する水性液剤を保存する容器に関しては、容器の光透過性を維持したままで、光に晒される環境下でもキノロン系抗菌化合物の含有率の低下を抑制することは重要な課題である。   As described above, with respect to a container for storing an aqueous liquid preparation containing a quinolone antibacterial compound, the decrease in the content of the quinolone antibacterial compound is suppressed even in an environment exposed to light while maintaining the light transmittance of the container. That is an important issue.

そこで、本発明者らは、可視光を透過し、かつ、水性液剤中のキノロン系抗菌化合物の含有率の低下を抑制できる容器について鋭意研究を行ったところ、酸化チタンを含有する合成樹脂製容器または紫外線遮断性フィルムで密着包装した容器に、キノロン系抗菌化合物またはその塩を含有する水性液剤を保存すれば、120万lux・hrという強力な光の照射下でも水性液剤中の該キノロン系抗菌化合物の含有率の低下を顕著に抑制できることを見出し、本発明に至った。   Therefore, the present inventors conducted extensive research on a container that transmits visible light and can suppress a decrease in the content of the quinolone antibacterial compound in the aqueous liquid. As a result, a synthetic resin container containing titanium oxide is obtained. Alternatively, if an aqueous solution containing a quinolone antibacterial compound or a salt thereof is stored in a container that is tightly packaged with an ultraviolet blocking film, the quinolone antibacterial in the aqueous solution even under irradiation of strong light of 1.2 million lux · hr The inventors have found that the decrease in the content of the compound can be remarkably suppressed, and have reached the present invention.
