  As dosage forms of oral solid preparations, tablets, capsules, granules, powders and the like are generally known. However, few of these dosage forms are easy to handle and easy to take. For example, tablets and capsules have a problem that it becomes difficult to swallow as the shape thereof becomes larger, and granules and powders have a problem that they are peeled off at the time of taking and a problem that they enter between teeth. Further, all of these dosage forms require water at the time of taking, and there is a problem that it is difficult to take while sleeping in an emergency or a serious patient.

  Chewable tablets are known as dosage forms that can be taken without water, but those currently offered are poorly disintegratable and difficult for elderly people and children with low chewing ability to take. There is a problem that.

  Accordingly, there is a demand for the development of an orally rapidly disintegrating tablet that can be easily taken without water and can be taken easily at any time and anywhere.

As a technique for producing such an intraoral rapidly disintegrating tablet, after filling an active ingredient and a saccharide suspended in an agar aqueous solution into a mold (resin film sheet for PTP packaging), it is solidified into a jelly shape, Furthermore, when a method of drying under reduced pressure or ventilation (Patent Document 1), or when a tablet material in a dry state containing a drug, a water-soluble binder, and a water-soluble excipient is transferred to the next manufacturing process as a tablet form A method (Patent Document 2) is known in which a molded tablet is humidified at a minimum pressure required to maintain its form to a hardness that can be maintained, and then the molded tablet is humidified and further dried. Yes.
However, these methods have a problem that a special manufacturing facility is required and the manufacturing process is complicated accordingly.

  Therefore, the development of solid preparations that can be manufactured with a simple manufacturing process using general manufacturing facilities for solid pharmaceutical preparations, exhibit excellent disintegration properties in the oral cavity, and have no practical problems. Is desired.
