Abstract: Disclosed are a method for producing an aripiprazole suspension, wherein the aripiprazole has a mean particle size of 1 to 10 ?m, the method comprising the steps of: (a) combining bulk aripiprazole and a vehicle to form a primary suspension; (b) subjecting the primary suspension to first pulverization using e.g., a high shear pulverizing machine, a dispersion machine that applies shear force to a material to be processed, a colloid mill, an ultrasonic dispersion machine, or a high-pressure jet type emulsifying dispersion machine to form a secondary suspension; and (c) subjecting the secondary suspension to second pulverization using e.g., a high-pressure jet type emulsifying dispersion machine to form a sterile final suspension; and a method for producing a freeze-dried formulation from the aripiprazole suspension.

Abstract: An object of the present invention is to provide a freeze-dried aripiprazole powder formulation that exhibits good dispersibility and is easily dispersed into a homogenous suspension when reconstituted with water.

Abstract: The present invention provides a medical device containing a cake composition comprising aripiprazole as an active ingredient and capable of suppressing agglomeration of aripiprazole in a suspension obtained by resuspending a freeze-dried substance; and a cake composition comprising aripiprazole as an active ingredient. The present invention relates to a medical device containing, in a storage container whose inner wall is treated with silicone, a freeze-dried cake composition comprising separately prepared aripiprazole as an active ingredient, wherein there is a space between the inner wall and the cake composition; and a cake composition comprising aripiprazole as an active ingredient and having a strength of 5 to 100 N.

Abstract: A dual chamber prefillable syringe (100) includes: a cylinder (10) which has a bypass portion (11); a hub luer-lock (20); a front stopper (30); a middle stopper (40) which seals a preparation (S) together with the front stopper (30); an end stopper (50) which seals a solvent (L) together with the middle stopper (40); a finger grip (60); and a plunger rod (70) which is connected to the end stopper from the rear end side. A female screw portion (64) which is screwed around the axis line is formed on an inner circumferential surface of the finger grip (60), and a male screw portion (73) which is able to be screwed to the female screw portion is formed on an outer circumferential surface of the plunger rod (70).
