An object of the present invention is to provide a liquid medicinal preparation which does not generate precipitates and is suitable for mass production. According to the present invention, provided is a liquid medicinal preparation that contains 1-(2-deoxy-2-fluoro-4-thio-&#x3b2;-D-arabinofuranosyl)cytosine or a salt thereof, a polyhydric alcohol having a molecular weight of 100 or less, and water. The polyhydric alcohol is preferably glycerin, propylene glycol, or butanediol.

Liquid medicinal preparation

Provided is a pharmaceutical composition which contains fulvestrant in an amount of equal to or greater than 8% by mass with respect to the entire mass of the pharmaceutical composition, an aqueous solvent satisfying (1) to (4), and a pharmaceutically acceptable nonaqueous carrier satisfying (A) and (B). (1) Ethanol is contained in an amount of equal to or greater than 8% by mass with respect to the entire mass of the pharmaceutical composition. (2) At least one kind of polyhydric alcohol selected from propylene glycol or 1,3-butylene glycol is contained in an amount of equal to or greater than 3% by mass with respect to the entire mass of the pharmaceutical composition. (3) A content of benzyl alcohol is less than 5% by mass with respect to the entire mass of the pharmaceutical composition. (4) A content of the aqueous solvent is 15% to 50% by mass with respect to the entire mass of the pharmaceutical composition. (A) A content of benzyl benzoate is less than 1% by mass with respect to the entire mass of the pharmaceutical composition. (B) A content of the nonaqueous carrier is 40% to 75% by mass with respect to the entire mass of the pharmaceutical composition.

Pharmaceutical composition

Provided is a pharmaceutical composition which contains fulvestrant in an amount of 4.5% by mass to 10.0% by mass with respect to the entire mass of the pharmaceutical composition, at least one kind of polyhydric alcohol selected from propylene glycol or 1,3-butylene glycol in an amount of 8% by mass to 23% by mass with respect to the entire mass of the pharmaceutical composition, benzyl alcohol in an amount of 5% by mass to 24% by mass with respect to the entire mass of the pharmaceutical composition, benzyl benzoate in an amount of 8% by mass to 19% by mass with respect to the entire mass of the pharmaceutical composition, and castor oil, and in which a content of ethanol is less than 1% by mass with respect to the entire mass of the pharmaceutical composition, and a content of benzoic acid is less than 1% by mass with respect to the entire mass of the pharmaceutical composition.
