Herein disclosed is a lyophilized pharmaceutical preparation obtained by lyophilizing an aqueous composition having property of reversible thermosetting gelation and comprising an effective amount of a drug, 0.2 to 2.1 (W/V)% of methylcellulose (the content of methoxyl group is within the range of 26 to 33%), 1.2 to 2.3 (w/v)% of citric acid and 0.5 to 13 (W/V)% of polyethylene glycol. The lyophilized pharmaceutical preparation makes it possible to stably store drugs unstable to water till they are put into practical use and, upon therapeutic use, an aqueous composition having property of reversible thermosetting gelation which can undergo gelation when locally applied can easily and immediately be reconstituted from the preparation by addition of a proper amount of a solvent for reconstitution.

摘要:
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.
