Description

Granules and their manufacturing method, and tablets

[0001] The present invention relates to granules suitably used for manufacturing pharmaceutical and food tablets, a method for manufacturing the same, and tablets using the granules.

[0002] There are two main methods for manufacturing tablets for pharmaceuticals and food products: one in which the raw materials are mixed and then compressed directly, and another in which the raw materials are granulated beforehand and then compressed. The method of pre-granulating the raw materials before compression has the advantage of producing tablets with uniform content, excellent fluidity during compression, and consistent performance. There are various granulation methods, including fluidized bed granulation, spray drying granulation, and dry granulation. Among these, spray drying granulation is advantageous in terms of productivity.

[0003] Furthermore, while the raw materials for tablets include not only the desired food ingredients and active ingredients, but also additives such as excipients, disintegrants, and lubricants, using a raw material that combines these additives into a single component can improve workability and increase the efficiency of tablet manufacturing.

[0004] To date, granules comprising sugars consisting of sugars and / or sugar alcohols, a disintegrant, and a hydrophilic lubricant have been proposed, which, when formed into tablets, satisfy predetermined physical properties of hardness, disintegration time, and in-oral disintegration time (see, for example, Patent Document 1).
