[0027]

The details of the mechanism by which the orally disintegrating composition of the present invention exhibits excellent orally disintegrating properties and appropriate strength as a pharmaceutical preparation are not clear, but are presumed as follows at present.

That is, the orally disintegrating composition of the present invention is obtained by molding a mixture containing an organic acid, a carbonate, a poorly water-soluble solid substance as a network maintainer, and a water-soluble saccharide as a coloring inhibitor at a considerably low molding pressure. Then, carbon dioxide gas and water are generated in the obtained molded body by a chemical reaction, and then the carbon dioxide gas and water are removed to obtain the molded product. Therefore, at the time of molding, the present composition has many voids inside due to a low molding pressure, and the strength should be insufficient as it is.

However, in the early stage of the generation and removal of carbon dioxide and water after molding, the water contained therein is released from all of the organic acids, carbonates, poorly water-soluble solid substances and water-soluble saccharides. Organic acids, carbonates and water-soluble saccharides are dissolved in the released water, and the dissolved organic acids and carbonates react to generate carbon dioxide gas and water. When the cycle is stopped, the composition is dried and solidified, a network of these raw materials is formed, and the composition is hardened, and the appropriate physical strength of the composition is realized. Note that the poorly water-soluble solid substance has a function of suppressing the expansion or contraction of the network when the network is formed, and contributes to maintaining the shape of the present composition.

As used herein, the term “network” refers to a connection between raw materials that gives the composition of the present invention an appropriate physical strength, and specifically, a connection between an organic acid and a carbonate. To a small amount of water generated locally by a chemical reaction,
A part of the raw material containing the organic acid and the carbonate, particularly the surface of the raw material particles is dissolved, and the raw material particles approach each other through the dissolved part, and as a raw material itself and a reaction product in the process of drying these. It refers to the interconnection of the raw materials and their reaction products, which are provided to the composition by curing in the amorphous or crystalline state.

On the other hand, the carbon dioxide gas and water generated with the progress of the above-mentioned phenomenon are scattered outside the present composition, so that an appropriate porosity can be obtained in combination with the above-mentioned low molding pressure (and networking). It is thought to promote rapid disintegration in the oral cavity. In addition, in the composition having voids therein as described above, in order to determine a delicate and good balance between the oral disintegration and tablet strength, the porosity and tablet strength defined in the present invention are used as a determination material. Is considered to be preferred.

[0032]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the orally disintegrating composition of the present invention will be described in detail. As described above, the orally disintegrating composition of the present invention contains an organic acid, a carbonate, a network maintenance agent and a coloring inhibitor, and the orally disintegrating formulation of the present invention contains The orally disintegrating composition is obtained by adding a medicinal ingredient to the orally disintegrating composition, and since both have almost common properties in disintegration and strength, both are described below.

Here, the active ingredient in the orally disintegrating preparation of the present invention is not limited by its shape or active area, and may be, for example, a central nervous system drug, a peripheral nervous system drug, a sensory organ drug. Medicine, allergy medicine, cardiovascular medicine, respiratory medicine, digestive medicine, hormonal medicine, urogenital and anal medicine, vitamin medicine, nutrient tonic altering medicine, blood and body fluid medicine, metabolic medicine, Cell stimulating drugs, tumor drugs, diagnostic drugs, drugs for physical disorders, antibiotics, chemotherapeutics, biological drugs, bioactive peptides, drugs for parasites, etc. One or more of these medicinal components can be used in combination.

The amount of the above-mentioned medicinal component depends on the nature thereof, but is not more than 80% by weight of the solid component, that is, the whole orally disintegrating composition of the present invention. Preferably 0.03 to
It is preferably 50% by weight, more preferably 0.03 to 20% by weight. If the compounding amount of the medicinal component exceeds 80% by weight, a favorable balance between the orally disintegrating property of the final product and the tablet strength cannot be obtained, which is not preferable.

The preparation of the present invention takes the form of a solid preparation, typically a tablet, but can be masked with a bitter mask or the like by a conventionally known method. Such masking can also be applied to the raw powder or granules of the medicinal ingredient and tableted.

The present composition contains, as essential components, an organic acid, a carbonate, a network maintaining agent and a coloring inhibitor, which will be described in detail below. The mixing ratio of these components is, by weight, a mixture of an organic acid and a carbonate. : Network maintainer: anti-coloring agent = 100: 2
5.0 to 625.0: 25.0 to 937.5. If the ratio is out of this range, the effects intended by the present invention may not be obtained, which is not preferable. Further, in the present composition, the mixing ratio between the organic acid and the carbonate is preferably set to an organic acid: carbonate = 1: 1 to 9: 1 by weight. Outside of this range, the effects intended by the present invention may not be obtained, which is not preferable.

First, preferred examples of the organic acid include L-tartaric acid, citric anhydride, lactic acid, dl-malic acid, fumaric acid, L-ascorbic acid and the like. -Tartaric acid and dl-malic acid and the like are particularly preferred. In the present invention, these organic acids can be used alone or in combination of two or more.
Such an organic acid performs a function of forming a network in addition to a function of generating water by reacting with a carbonate in the decarboxylation gas and dehydration step in the production of the present composition.

The content of the organic acid in the orally disintegrating composition of the present invention is sufficient as long as the obtained composition can achieve the intended orally disintegrating properties and tablet strength. It is 4.0 to 60.1% by weight, preferably 15.0 to 40.0% by weight. When the content of the organic acid is less than 4.0% by weight or more than 60.1% by weight, a good balance between the orally disintegrating property and the tablet strength in the final product cannot be obtained, which is not preferable.

Preferred examples of the carbonate include sodium bicarbonate, potassium bicarbonate and sodium carbonate. The water generated in the above-mentioned networking of the raw materials and the reaction with the organic acid may be used. From the viewpoint of rapid dissolution, a carbonate easily soluble in water can be particularly preferably used.

These carbonates may be used alone or in combination of two or more. The content of the carbonate in the present composition is not limited as long as the desired properties can be realized as described above. However, it is usually 0.8 to 33.4% by weight, preferably 2.5 to 15.0% by weight. When the content of the carbonate is less than 0.8% by weight or more than 33.4% by weight, a good balance between the orally disintegrating property and the tablet strength in the final product cannot be obtained, which is not preferable.

Next, corn starch, potato starch, sodium carboxymethyl starch, crystalline cellulose, low-substituted hydroxypropylcellulose or croscarmellose sodium are used as network maintainers.
And a poorly water-soluble solid substance according to any mixture thereof. This network maintaining agent has a function of suppressing deformation of the present composition (solid) due to expansion and contraction caused by expansion and shrinkage caused by the above-described decarbonation gas and dehydration step, and reduction of voids.
In addition, when this network maintenance agent is not added, the obtained orally disintegrating composition or the like shrinks and becomes too hard in a heating step described later, and dissolution in the mouth becomes poor.

The amount of the network maintainer is usually 16.0 to 50.0% by weight, preferably 25.0 to 5% by weight.
0.0% by weight. The amount of the network maintainer is 1
If the content is less than 6.0% by weight, the tablet shrinks and becomes too hard in the heating step described later, so that the dissolution in the mouth becomes poor, and 50.0% by weight
If it exceeds, sufficient tablet strength cannot be obtained, which is not preferable.

On the other hand, water-soluble saccharides related to erythritol, xylitol, mannitol, lactose and any mixture thereof are used as the coloring inhibitor. As lactose, isomerized lactose, reduced lactose, and the like are used. In addition, if this coloring inhibitor is not added, the obtained orally disintegrating composition and preparation will have a poor taste at the time of ingestion, and the tablet will be discolored in the manufacturing process.

The content of the coloring inhibitor is usually 16.
It is 0 to 75.0% by weight, preferably 16.0 to 60.0% by weight. If the content of the coloring inhibitor is less than 16.0% by weight, the tablet will be discolored in the production process, and if it exceeds 75.0% by weight, sufficient tablet strength cannot be obtained, which is not preferable.

The orally disintegrating composition of the present invention has a suitable orally disintegrating property as described above, and a porosity suitable as an index thereof is 30 to 60%. The porosity of the orally disintegrating preparation of the present invention is in accordance with this. Here, the porosity is obtained by measuring the tablet volume and the total pore volume by a mercury intrusion method, and using the measured values, the following formula (1) porosity (%) = (total pore volume / tablet volume) ) × 100 (1). This porosity is 3
If it is less than 0%, it takes time to disintegrate in the oral cavity, and if it exceeds 60%, sufficient strength may not be obtained, which is not preferable.

As described above, the compositions and preparations of the present invention have excellent disintegration properties in the oral cavity and high physical strength (tablet strength). As described above, it is an advantage of the present invention to combine good disintegration in the oral cavity and appropriate strength in a formulation. For example, the tablet strength is usually 1 to 10 kp,
Preferably, it is about 1.5 to 7 kp. The dissolution in the mouth (the time required for the tablet to completely disintegrate with the saliva in the mouth of a healthy adult male) is usually within 1.5 minutes, preferably within 1 minute. Further, the disintegration time (measured by the disintegration test method described in the Japanese Pharmacopoeia 13th Edition) is usually within 1 minute, preferably within 30 seconds.

The essential components of the composition are the above-mentioned organic acids, carbonates, network maintainers and color inhibitors, but are generally used in the production of tablets as long as they do not adversely affect the disintegration and other properties described above. It is also possible to include additives of the type used. Such additives include, for example, binders, lubricants, sweeteners, flavors, coloring agents and the like.

Examples of the binder include hydroxypropylcellulose, hydroxypropylmethylcellulose, polyvinylpyrrolidone and methylcellulose.

As the lubricant, for example, magnesium stearate, calcium stearate, stearic acid,
Examples include sucrose fatty acid esters, talc, polyethylene glycol and the like.

As sweeteners, erythritol, xylitol, mannitol, lactose, saccharin sodium,
Glycyrrhizin dipotassium, aspartame, stevia, thaumatin and the like can be mentioned. Examples of the flavor include lemon, lemon lime, orange, and menthol. As a coloring agent, for example, food yellow 5
No. 5, food red No. 5, food lake color, iron sesquioxide, yellow iron sesquioxide and the like.

The above-mentioned additives can be used alone or in combination of two or more. Further, these additives can be added at any stage of the production process. That is, these additives can be added in an appropriate amount at any time during the mixing of the organic acid, the carbonate, the network maintaining agent, and the coloring inhibitor, at the time of granulation or immediately before molding.

Next, a method for producing the orally disintegrating composition of the present invention will be described. As described above, in the present manufacturing method,
First, an organic acid, a carbonate, a network maintenance agent and a coloring inhibitor are mixed, and the molding mixture is mixed at 1 to 130 kg / c.
molding in a molding pressure of m ^2. Then, the obtained substantially dry molded body is heated at 40 to 120 ° C. to release carbon dioxide gas and moisture from the molded body and form a network of the above four components. An orally disintegrating composition in the form of a tablet having strength and disintegration properties can be obtained.

Here, the compounding amounts of the above four essential components are, as described above, 4.0 to 60.1% by weight of an organic acid and 0.1% of a carbonate.
8-33.4% by weight, network maintainer 16.0-5
0.0% by weight, and 16.0 to 75.0% by weight of a coloring inhibitor.

The method of mixing is not particularly limited, and the mixing can be performed as it is or after granulating the raw material such as the organic acid. In the present invention, the obtained molding mixture is substantially used. It is necessary that the molded body obtained in the next step be substantially dried. Here, the “substantially dry state” means that the moisture content measured by the Karl Fischer method is 5 w / w% or less. If the molding mixture is not in a substantially dry state, sticking is likely to occur at the time of tableting, and it may not be possible to continuously and quantitatively supply the raw material powder for molding.

The raw material can be granulated before or after mixing the raw materials, and the raw materials can be mixed in their entirety, individually or in any combination. It is preferable that this mixture can be smoothly supplied to a tablet molding machine in a subsequent molding step. Further, as the granulation method, it can be performed either dry or wet, but when wet granulation is performed, from the viewpoint of the above-mentioned reasons and the productivity during compression molding,
Before molding, it is necessary to remove water until it reaches a substantially dry state.

A single-shot tablet machine or a rotary tablet machine is generally used for molding the molding mixture. However, the present invention is not limited thereto, and a tablet machine with special specifications can be used. Molding pressure for tableting is usually 1 to 130k
g / cm ² , preferably 10 to 100 kg / cm
² , more preferably 20 to 80 kg / cm ² . If the molding pressure is less than 1 kg / cm ² , the molded product is easily damaged in the subsequent manufacturing process, and if it exceeds 130 kg / cm ² ,
The disintegration of the final product in the oral cavity is poor, which is not preferable.

When the orally disintegrating preparation of the present invention is prepared by adding a medicinal ingredient to the composition, the medicinal ingredient may be added before the above-mentioned molding. The amount of the above-mentioned organic acid and / or carbonate can be appropriately changed depending on the acidity / basicity of the target medicinal ingredient.

The molded body obtained as described above is in a substantially dry state, and then heated to release carbon dioxide and water from the molded body, and at the same time, the networking is performed. Is done. In addition, in the conventional method for manufacturing an orally disintegrating tablet, as described in JP-A-5-27054 and JP-A-8-291051, water is added to a molding mixture or a molded body itself. It is practiced that the molded body is wetted and then dried to obtain a tablet. However, in the present invention, such a water addition step is unnecessary, and the production cost is reduced by omitting one step. be able to.

Further, the above-mentioned heating to networking step is derived from the knowledge of the present inventors and shows the remarkableness of the present invention, and is unparalleled in other formulation techniques. Yes, it offers the opposite motivation.

That is, in the case of an effervescent tablet containing an organic acid and a carbonate, such heating has conventionally been regarded as a matter which must be strictly avoided since such effervescent tablet is deteriorated. In the case of effervescent tablets having a two-layer structure, by adopting such a layer structure, the area in which the carbonate and the organic acid are in direct contact with each other is reduced as much as possible to prevent the storage stability from deteriorating. ing. Furthermore, when a carbonate is coexisted with an organic acid and placed in a packaging container, a reaction occurs due to a small amount of moisture, so that the internal pressure of the packaging container increases due to the generation of carbon dioxide gas, and the container may swell, possibly causing damage. is there. It is known that when such a situation occurs, the commercial value is lost and the consumer's credibility is lost.

To avoid such a situation, Japanese Patent Application Laid-Open No.
No. 13714 discloses a method in which a double salt of a carbonate and a borate is prepared in advance, and an organic acid is added thereto. JP-A-58-105910 discloses a method in which polyethylene glycol (hereinafter abbreviated as "PEG") and another foaming component are blended and then heated and melted to embed the foaming component in the PEG. Have been. Further, JP-A-61-176519 discloses a method in which an organic acid which does not release water of crystallization at 50 ° C. or less and PEG are heated and melt-mixed, then cooled and powdered, and sodium bicarbonate and sodium carbonate are added thereto. It has been disclosed. These techniques are all proposed to prevent the composition from becoming unstable due to the coexistence of the carbonate and the organic acid, and are techniques devised so that the carbonate and the organic acid do not react.

On the other hand, in the present invention, in the manufacturing process, the organic acid and the carbonate are positively brought into contact with each other and heated to cause a part of them to react, whereby the strength of the obtained tablet is improved. And In addition, the storage stability of the present composition is improved by performing the heating to networking steps.

Although the details of this reason are not always clear at present, the carbon dioxide gas and water content of the organic acid particles and the carbonate particles adjacent or close to each other in the molded product by the predetermined heating-networking process of the present invention. In the process of forcibly performing the formation reaction, these are neutralized to form a network and harden, while the organic acid particles and the carbonate particles that did not participate in the carbon dioxide and water generation reaction are affected by such a reaction. It is isolated by the network to suppress direct contact and reaction with each other, thereby improving the storage stability of the tablet. In addition, in the tablet, the organic acid and carbonate in an amount required for rapid disintegration at the time of oral administration and a suitable mouthfeel remain in a well-balanced manner, so that the effects intended by the present invention are obtained. It is assumed that

The inventors of the present invention have confirmed that carbon dioxide gas and water are generated from the molded product by the chemical reaction between the organic acid and the carbonate in the above heating step.
It has been proved by an experiment using a fully automatic thermal desorption spectroscopy device (see FIGS. 1 and 2). That is, from the molded body having the same formulation as that of Example 2 described later, generation of carbon dioxide and water was detected when the temperature reached around 120 ° C. in about 10 minutes from the start of heating. In contrast, erythritol was replaced with mannitol in the formulation of Comparative Example 5 described later, that is, this formulation did not contain an organic acid, but generation of carbon dioxide and water due to a chemical reaction was not detected.

The carbon dioxide gas and water generated as the heating-to-networking process proceeds are scattered out of the present composition, so that the carbon dioxide gas and water can be combined with the above-mentioned low molding pressure (and networking) to give an appropriate amount. It is thought to promote porosity and achieve rapid disintegration in the oral cavity.However, organic acids and carbonates involved in the generation of carbon dioxide and water are not only rapidly formed in the oral cavity but also in the network. It is involved in the melting of the mouth and the appropriate mouthfeel, and not all of them are scattered. Therefore, in this respect, the idea of the present invention is completely different from the technology described in Japanese Patent No. 2640570 in which the volatile components such as ammonium bicarbonate are simply volatilized to realize a porous tablet.

The heating of the molded body can be performed using, for example, a microwave dryer or a ventilation dryer. The heating temperature is such that the obtained composition or preparation (particularly, tablet) has the above-mentioned porosity, tablet strength, etc., and the strength required in the manufacturing process, the packaging process, the distribution process, and the handling of the patient is excellent. Any temperature may be used as long as it can exhibit oral disintegration. Specifically, the heating temperature is 40 to 120 ° C, preferably 60 to 120 ° C. The upper limit of the heating temperature is preferably equal to or lower than the melting point of the added additive or medicinal component, but as long as the strength required for handling is obtained and the property of rapidly disintegrating in the oral cavity is obtained. However, the present invention is not limited to this.

Since the tablet according to the orally disintegrating composition of the present invention obtained as described above is supposed to be orally administered as it is, its weight and size naturally have an appropriate range. Typically, about 100-1000 mg,
Those having a range of about 6 to 12 mmφ × 2 to 6 mm (thickness) are preferable. If the weight and size deviate from the above range,
The physical volume ratio occupied in the oral cavity is high, making it difficult to take, which is not preferable.

[Table 32]

The following can be understood from Tables 31 and 32. From Comparative Examples 9 to 12, it is not possible to obtain tablets having desired tablet strength and dissolution time in the mouth only with water-soluble saccharides or wet-granulated water-soluble saccharides. It is clear that salts and network maintainers are needed. Furthermore, from Comparative Examples 4 and 5, even when either the organic acid or the carbonate was not present,
The desired tablet strength was not obtained, which demonstrates that the neutralization reaction between the organic acid and the carbonate is responsible for the increase in tablet strength.

When no network maintaining agent is added as in Comparative Example 7, the tablet shrinks in the heating step, and the porosity decreases. As a result, although the tablet strength increases, the desired dissolution in the mouth cannot be obtained. On the other hand, in Comparative Example 6 in which the anti-coloring agent was removed, although the desired tablet strength and dissolution in the mouth were obtained, the taste at the time of ingestion was poor, and it was not preferable as an orally disintegrating tablet. Furthermore, coloring (discoloration) in the heating process
There is also a disadvantage of doing so. From the above, in the present invention, network formation, that is, increase in physical strength, is achieved between an organic acid, a carbonate, and a network maintainer. In this regard, a water-soluble saccharide is an essential component, and Many peripheral patents that obtain tablet strength by blending and the present invention have different technical ideas.
