Description of the Related Art As the aging society progresses rapidly, conventional oral solid pharmaceutical preparations such as tablets, capsules, granules and powders sometimes have difficulty in taking them. In the case of elderly people, taking tablets and capsules depends on their size due to a decrease in swallowing ability, and when granules and powder are left in the oral cavity, discomfort will remain. In addition, since the oral solid preparation requires water at the time of administration, it is often the case that a large amount of water is required due to difficulty in administration. Since the morbidity of chronic diseases increases with the age of the elderly, development of practical preparations suitable for long-term administration and easy to drink and handle has been desired in recent years. For example,
Oral rapidly disintegrating tablets, paste-like preparations and jelly-like preparations are mentioned.In particular, oral disintegrating tablets disintegrate or dissolve quickly in the oral cavity after ingestion. It can be easily taken as appropriate and is suitable for not only elderly people but also children.

段が提案されている。[0003] In general, the disintegration and hardness of a tablet are in an opposite relationship to each other, and the hardness must be reduced in order to increase the disintegration. However, tablet hardness is an important factor in the manufacturing, packaging and distribution processes, as well as in taking out from packaging when taking. A tablet having insufficient hardness cannot maintain its shape in the above-mentioned steps, and furthermore, it is difficult to accurately administer a dose. Therefore, it is desired to develop a technique for producing a rapidly disintegrating oral tablet having appropriate hardness and rapid disintegration, and the following various means have been proposed.

0)). However, this manufacturing method requires a freeze-drying manufacturing facility and requires a long time for manufacturing, so that the manufacturing cost tends to be high. Further, the obtained tablet has such a low hardness that it cannot be extruded from a PTP (Press Through Package) package, which is a general-purpose packaging material. Therefore, a special packaging material for removing the tablet by peeling off the seal on the back surface of the container is required. Tablets are easily broken or cracked during the manufacturing process or when taken out of the packaging material, and the handleability is not satisfactory for elderly people.

いる。On the other hand, as a rapidly disintegrating intraoral tablet produced by compression-molding a wet granulated product, for example, JP-A-5-271
No. 054 describes a tablet produced by tableting a granulated product containing a pharmaceutically active ingredient, a saccharide, and water to such an extent that the particle surface becomes wet. In addition, International Publication WO95 / 2038
No. 0 describes a tablet produced by compression-molding a granule containing a saccharide having low moldability and a saccharide having high moldability. The method for producing these tablets employs a wet granulation step of spraying and drying a physiologically acceptable organic solvent or water. Further, Japanese Patent Application Laid-Open No. 8-291051
JP-A No. 7-1980 describes a manufacturing method that requires a humidification and drying step using a special device as an additional step after compression-molding a granulated substance containing a medicinal ingredient, a water-soluble binder and a water-soluble excipient. Have been. In addition, International Publication WO97 / 4728
No. 7 discloses a method for producing a rapidly disintegrating tablet in the oral cavity, which comprises granulating a mixture containing a medicinal ingredient, a saccharide having an average particle diameter of 30 μm or less, and a disintegrant, followed by granulation. This production method is characterized in that saccharides are pulverized before the granulation step, and the particle diameter of the saccharides to be blended is adjusted to 30 μm or less as described above. In addition, such a wet granulation process is necessary to improve the compressibility of each component at the time of tableting and to increase the tablet hardness, but it involves humidification and drying, and thus has an unstable drug effect against water and heat. The problem remains that the components cannot be adapted.

It is necessary to include some steps in the production process for improving the dissolution property of the compound. Examples of such a step include formation of a complex of a medicinal ingredient and a pharmaceutical additive, miniaturization of medicinal ingredient particles by a solid dispersion or a mixing and pulverization technique, and the like. However, whichever method is used, the manufacturing process becomes more complicated because a new process is added.

い。Hereinafter, the present invention will be described in detail. In the orally rapidly disintegrating tablet of the present invention, "appropriate hardness" is 3 kg or more, preferably 5 kg or more in a usual hardness test specifically described later, and is caused by attrition of the tablet in a normal production process and a distribution process. It means hardness with little weight loss and almost no cracks. Further, the tablet hardness of 3 kg or more of the present invention can be applied not only to PTP packaging but also to a bottle container in which a tablet is sealed in a glass or plastic container. It is believed that it can withstand contact between the container walls sufficiently. The term "rapidly disintegrates" refers to the fact that, when orally administered to a healthy adult, the patient does not take water and receives one minute 3
The disintegration means that the whole tablet disintegrates and disperses within 0 seconds, preferably within 1 minute, more preferably within 40 seconds. It should be noted that the present tablet can be applied to a person who has a dry or low saliva in the oral cavity by using water enough to wet the oral cavity. Furthermore, the present tablet can be taken with water as it is, similarly to a normal tablet.

いことなどの特徴を有している。In the present invention, the saccharide used as the main excipient means monosaccharides and disaccharides which can be used in the technical field of pharmaceutical preparations, and their sugar alcohols. Specific examples thereof include mannitol, erythritol, xylitol, lactose and glucose, as well as maltose, sorbitol, trehalose, sucrose and fructose. These can be used alone or in combination of two or more. The former is preferably mannitol, erythritol, xylitol, lactose, etc., and in particular, mannitol has good sweetness and coolness, low hygroscopicity, moderate hardness and quick disintegration, and thus palatability. , Stability and manufacturability. When a saccharide having low moldability such as mannitol is used in the orally rapidly disintegrating tablets disclosed in the above publications, for example, a saccharide having low moldability is added to a saccharide having high moldability to granulate (International Published WO95 / 203
No. 80) or a tablet obtained by pulverizing the entire amount of saccharides having low moldability contained in a tablet and then adding a disintegrant to granulate (see WO 97/47287). A technique for improving the compression moldability is described. However, the present invention has such features that even a sugar having low formability can be contained in a tablet in an uncrushed state at about 80% by weight, and a wet granulation step involving humidification and drying is not required. ing.

ものと考えられる。In general, in order to increase tablet hardness, for example, polyvinylpyrrolidone, hydroxypropylmethylcellulose, methylcellulose, polyvinyl alcohol and the like are used as a water-soluble binder. Does not show any disintegration.
In the present invention, without using such a water-soluble binder, in order to add an appropriate amount of a co-ground product of a saccharide and a disintegrant, a suitable hardness by a simple direct compression method that does not require a granulation step. Tablets that have and rapidly disintegrate in the mouth can be formed. Without being bound by theory, according to the tablets of the present invention, the particles or powder of the saccharide and disintegrant finely divided by a particular pulverizing method may be unmilled saccharide particles considerably larger than these particles. Etc., the contact area between each particle or powder significantly increases,
For this reason, it is considered that although a mixture of these particles is merely subjected to compression molding, it has a certain hardness, but on the other hand, it does not substantially use a binder such as a water-soluble polymer, so that it exhibits rapid disintegration.

Co-ground means that the saccharide and the disintegrant are ground together as a mixture. Therefore, as will be described in detail later, in a co-ground product according to the present invention from a mixture obtained by separately grinding a saccharide and a disintegrant, one is expected to act as the other grinding aid, so Is thought to be further promoted.

When the tablet is compressed at 0 kg, a tablet having a hardness of 3 kg or more and disintegrating in the oral cavity within 1 minute and 30 seconds can be obtained. In addition to using co-milling as described above, the disintegrant is
In general, the compound has an effect of promoting the bonding between particles to some extent, and depending on the compounding amount, may contribute to increasing the tablet hardness while maintaining the quick disintegration property of the tablet. However, when a part of the saccharide having low formability such as mannitol is not used in the form of a co-ground product, it is necessary to include a large amount of the above-mentioned disintegrant in order to maintain an appropriate hardness in the compression-formed product. However, the tablets produced in this manner are likely to cause discomfort due to the residual disintegrant in the oral cavity when ingested, and cannot provide a rapidly disintegrating oral tablet without water. Incidentally, instead of using the co-ground material of mannitol and disintegrant, each plain crushed material of mannitol and disintegrant may be mixed and then added to the unground material of mannitol or the unground material of mannitol and disintegrant. ,
It was extremely difficult to obtain a compression-molded product having an appropriate hardness.

ていることが理解できるであろう。Next, the production method of the present invention will be described in detail. In the production method of the present invention, first, the disintegrant is added to a part of the saccharide as the main excipient, and then the mixture is pulverized to prepare a co-ground product of a mixture of the saccharide and the disintegrant. At that time, if necessary, a medicinal ingredient and other additives may be simultaneously added to prepare a co-ground product. Particularly, in the case of a poorly water-soluble medicinal ingredient, it is possible to make the medicinal ingredient particles finer by adding the mixture to the co-grinding step, and to dissolve the poorly water-soluble medicinal ingredient without changing or adding a manufacturing process. Can be easily improved. This means that, for example, when a poorly water-soluble medicinal ingredient is co-ground with a low molecular weight water-soluble excipient such as a saccharide, the physicochemical properties of the medicinal ingredient, for example, without changing the crystal form, can easily be one to several. μm,
In some cases, it can be understood from the fact that it is known that the particle size can be reduced to 1 μm or less (powder and industrial, 2
4 , 53-59 (1992)). It is also known that when a poorly water-soluble medicinal ingredient is co-ground with the above-mentioned disintegrant crospovidone, the dissolution property of the medicinal ingredient is improved (Kollidon R , Kollidon R , 2nd edition, BASF, pp. 171). -173 (199

な粉砕機の使用は避ける方がよい。The above-mentioned pulverizing step of the mixture is a dry pulverization method which does not use water, which has been conventionally used, and a pulverizer which can be preferably used is a pulverizing type such as a mortar, a ball mill, a rod mill, a vibrating ball mill, and the like. Vibrating rod mill and the like. Specifically, for example, the saccharide and the disintegrant are charged into the vibrating rod mill such that the weight ratio of the saccharide and the disintegrant is 3: 1 to 19: 1 in the co-ground product, and it differs depending on the model used, the charged amount, the amount ratio, and the like. 5 minutes or more, preferably 5 to 2
Mill for 0 minutes. The same applies to the case where necessary amounts of a medicinal ingredient and other additives are added and pulverized at the same time. However, when adding a poorly water-soluble medicinal ingredient, it is necessary to set the charge amount and the pulverization time so that the desired elution of the medicinal ingredient from the tablet is achieved. The production temperature is generally room temperature (2
0-30 ° C.), and there is no particular need to adjust,
With respect to humidity, it is preferable in terms of manufacturing that the relative humidity be 60% or less in consideration of moisture absorption such as types in the pulverization process. In addition, collision-type pulverizers, for example, a hammer mill, a jet mill, etc., generally cannot be sufficiently pulverized, and often only tablets having a moderate hardness are obtained.
It is better to avoid using such a crusher for the purpose of improving the dissolution of poorly water-soluble medicinal components.

At that time, if necessary, a medicinal ingredient and other additives can be added simultaneously to prepare a tableting powder. In this mixing step, a plastic bag, a V-type mixer, or the like used for ordinary physical mixing is used, but is not limited to these means. However, the number of times or the time of mixing may be determined by the amount of the lubricant compounded as necessary to maintain the uniformity of the medicinal component in the powder for tableting and prevent tableting trouble during compression molding (for example, sticking). Set the effects and so on. In addition, when the fluidity of the tableting powder is low, the saccharide as the main excipient used in the mixing step is used as long as it does not adversely affect the hardness and disintegration of the tablet obtained in the tableting step.
