The present invention has an object to provide an antibacterial aqueous pharmaceutical composition and an aqueous pharmaceutical composition which have a sufficiently low gelation temperature even when new quinolone antibacterial agents such as ofloxacin as the active ingredient and can be retained at the administration site for a long time by virtue of rapid viscosity increase after administration in spite of their being liquid at administration and thereby attain high availability of pharmaceutical agent.
The present invention relates to an antibacterial aqueous pharmaceutical composition
which comprises: 2.8 to 4 w/v % of methylcellulose, the 2 w/v % aqueous solution of which has a viscosity of 12 mPa.s or below at 20° C.; 1.5 to 2.3 w/v % of citric acid; 2 to 4 w/v % of polyethylene glycol; and 0.1 to 0.5 w/v % of ofloxacin.
本发明的目的是提供一种抗菌
水性药物组合物和一种
水性药物组合物,即使以新的喹诺
酮类抗菌剂(如
氧氟沙星)作为有效成分,其凝胶化温度也足够低,并且尽管在给药时是液体,但由于给药后粘度迅速增加,可以在给药部位保留很长时间,从而获得高的药剂利用率。
本发明涉及一种抗菌
水性药物组合物,它包括
其中包括:2.8 至 4 w/v % 的
甲基纤维素,其 2 w/v % 的
水溶液在 20°C 时的粘度为 12 mPa.s 或以下;1.5 至 2.3 w/v % 的
柠檬酸;2 至 4 w/v % 的聚
乙二醇;以及 0.1 至 0.5 w/v % 的
氧氟沙星。
