A preparation which contains acetaminophen at a high content, in particular, a miniaturized tablet (conventional tablets, sustained-release tablets, etc.) which have excellent dissolution properties, preferable hardness and high drug content uniformity and a manufacturing method thereof. Acetaminophen has a preset particle size and is used for manufacturing a preparation, the flowability of acetaminophen can be improved so that secondary agglomeration can be suppressed, manufacturing efficiency can be elevated and the cost for manufacturing is also reduced. Thus, an acetaminophen preparation having improved administrability, for example, a reduced size and a manufacturing method thereof are highly useful.

Acetaminophen preparation, and method for producing same

A method for manufacturing a preparation which contains acetaminophen at a high content, in particular, a miniaturized tablet (conventional tablets, sustained-release tablets, etc.) which have excellent elution properties, preferable hardness and high drug content uniformity, and a premix drug substance of acetaminophen which has improved manufacturability. According to the method in which acetaminophen having a preset particle size is used for manufacturing a preparation, the flowability of acetaminophen can be improved so that secondary agglomeration can be suppressed and manufacturing efficiency can be elevated. Thus, this method is highly useful for manufacturing an acetaminophen preparation having improved administrability, for example, a reduced size.
