A major object of the present invention is to provide an effective means for promoting polyamine synthesis in an organism (in particular, in humans).


The present invention provides a medicament having a wider treatment spectrum, causing a fewer side effects and superior in tolerability and safety, as compared to known typical antipsychotic agents and atypical antipsychotic agents. The present invention related to a medicament containing (I) a compound which is 7-[4-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)butoxy]-1H-quinolin-2-one or a salt thereof, and (II) at least one drug selected from the group consisting of a mood stabilizer, a serotonin reuptake inhibitor, a norepinephrine reuptake inhibitor, a serotonin and norepinephrine reuptake inhibitor, a noradrenergic and specific serotonergic antidepressant, an antianxiety drug, a tricyclic antidepressant, a tetracyclic antidepressant, an antipsychotic drug and an anti-ADHD drug, in combination.


A suspension and a cake composition are provided in which agglomeration of the active ingredient that is caused when silicone oil and/or silicone oil derivative is contained therein can be suppressed without a special treatment, such as sonication. The suspension contains, in a dispersion medium, an active ingredient of a specific mean primary particle size, and silicone oil and/or silicone oil derivative. The cake composition contains an active ingredient of a specific mean particle size, and silicone oil and/or silicone oil derivative.


[Object] An object of the present invention is to provide an oral solid preparation that can be produced in a simpler manner than conventional methods, that exhibits high bioavailability and high dissolubility even in persons having low stomach acid, and that can also ensure dissolubility after being allowed to stand for a certain period of time. Another object is to provide a simple method for producing the oral solid preparation. [Means for Achieving the Object] The present invention relates to an oral solid preparation comprising, as an active ingredient, a finely milled powder obtained by milling a highly hygroscopic aripiprazole anhydrous crystal, and a pharmaceutically acceptable carrier, the finely milled powder having a mean particle size of 10 m or less; and a method for producing an oral solid preparation comprising the steps of (1) milling a highly hygroscopic aripiprazole anhydrous crystal into a finely milled powder having a mean particle size of 10 m or less, and (2) mixing the obtained finely milled powder with a pharmaceutically acceptable carrier.
