Description

Package

The present invention relates to a package, and more particularly to a package having high hygroscopicity and gas adsorbability and high moldability.

Conventionally, a press-through pack (PTP) package has been widely used for packaging pharmaceutical products. The PTP package is a package in a form that is sealed with a lid material that is easy to tear after the packaged material is accommodated in the container, and the lid material is torn by pressing from the container side toward the lid material side. Is taken out. Since such a PTP package is excellent in airtightness, handleability, portability, and productivity and can save resources, it is expected that the future demand will be further increased as a package for pharmaceutical products.

As the material on the container side of the PTP package, it is common to use a single layer of a polypropylene sheet or a polyvinyl chloride sheet, or a laminate composed of a plurality of materials in which a film or the like is laminated on an aluminum foil. Moreover, as the material on the lid member side, an aluminum foil coated with a resin is often used.

In this way, among the packaging bodies in which various materials are used, when a drug that decomposes with moisture is contained or the packaged body is highly hygroscopic, water permeability can be used as the packaging body material. Polyvinylidene chloride, PCTFE (chlorofluoride trifluoride resin), etc., which have a low viscosity, were used, and the moisture resistance was improved by sealing.

However, even if packaging that seals against a hydrolyzable or highly hygroscopic package body, there is moisture permeability from the surface of the pocket (portion that contains the package body) or from the end of the lid. Since the moisture-proof property is insufficient, there is a problem that the protective effect of the packaged body is relatively small.

On the other hand, Patent Document 1 proposes a PTP package having a configuration in which a container using a highly moisture-proof aluminum foil and a lid material are bonded together. In the PTP package of Patent Document 1, the aluminum foil constituting the container is provided with a polyamide-based resin layer that is stretched on one side, and a thermal adhesive layer is provided on the other side. And it can be set as the moisture-proof PTP package by heat-sealing the aluminum foil of the structure similar to the aluminum foil which comprises the cover material containing an aluminum foil, or a container, and a container.

In Patent Document 2, a technique is proposed in which a moisture absorbing layer is provided in a container of a PTP package and a drying function is imparted to the PTP package. Since the PTP package provided with a drying function can cause the drying function to act on the package, it can be stored well even if the package is hydrolyzable or highly hygroscopic. can do.

Japanese Patent No. 3983131 JP 2006-327690 A

In the technique disclosed in Patent Document 1, aluminum having high moisture resistance is used as a material constituting the container, and the lid member is also made of aluminum. And by heat-sealing the container and the lid material, it is possible to provide a PTP packaging body having moisture resistance. However, when the package body is enclosed, the portion in which the package body is enclosed ( There was a problem that the water remaining inside the storage part) could not be removed, and the quality of the solid preparation was impaired. Therefore, a PTP package having a capability of absorbing moisture as well as moisture is desired. Further, depending on the package, there is a property that the decomposition is further promoted by the gas generated at the time of decomposition. Therefore, a PTP package capable of adsorbing not only moisture but also gas has been desired.

On the other hand, in the technique disclosed in Patent Document 2, by providing a moisture absorbing layer, a PTP packaging in which a drying function is provided to the packaged body and the inside (container) in which the packaged body is sealed is provided. It can be a body.

The PTP package (blister package) disclosed in Patent Document 2 creates a film by bonding a moisture-absorbing layer to a moisture-proof barrier layer, and forms a PTP package by using this film. At this time, the film provided with the barrier layer and the moisture absorbing layer is formed with an accommodation portion for accommodating an object to be packaged in a heat-softened state.

As described above, in the technique of performing molding by heating, there is a disadvantage that the moldability may be lowered when the thermal shrinkage rate of each layer is different. Therefore, a technique capable of providing a PTP package having hygroscopicity and good moldability has been desired.

Moreover, in the PTP package, when the rigidity of the accommodating part (pocket) for accommodating the packaged body is insufficient, not only is it difficult to accommodate the packaged object inside, but an external force is applied to the accommodating part. Since the housing portion is easily crushed, the effect of protecting the sealed packaged body is small. Furthermore, when the film which comprises a package does not have moderate rigidity, when forming the accommodating part of a package, a moldability falls. Therefore, there has been a demand for a technique capable of ensuring moisture resistance, having appropriate rigidity, and physically protecting the packaged body.

An object of the present invention is to provide a package having a hygroscopic property and a gas adsorbing property and having good moldability. In addition, another object of the present invention is to provide a package body having a hygroscopic property and a gas adsorbing property and having an appropriate rigidity.

The object is to provide a package containing a solid preparation containing solifenacin succinate or 1-{[(α-isobutanoyloxyethoxy) carbonyl] aminomethyl} -1-cyclohexaneacetic acid according to the package according to the present invention. The package body is provided with a container sheet in which a concave container for containing the solid preparation is formed, and a lid sheet with airtightness for sealing the solid preparation, The container sheet is composed of a packaging film in which an adsorption layer, at least one base layer composed of a resin, an aluminum foil, and a barrier layer are laminated, and the adsorption layer includes the base layer and the base layer. This is solved by being laminated and disposed on the side where the solid preparation is accommodated, and containing at least zeolite.

Thus, since the container sheet constituting the package of the present invention includes the adsorption layer containing zeolite on the side where the solid preparation is accommodated, water in the accommodating portion and other molecules (gas molecules) Can be adsorbed. Furthermore, since the container sheet is provided with a highly moisture-proof aluminum foil, the moisture resistance of the package is dramatically improved by being combined with the adsorption layer.
Moreover, since the packaging body film which comprises the container sheet | seat of the packaging body of this invention is equipped with the base material layer laminated | stacked on an adsorption layer, moderate rigidity is provided. Therefore, at the time of manufacture of the container sheet provided with the accommodating portion, the moldability is good, and the accommodating portion in which the solid preparation is accommodated also has appropriate rigidity. Therefore, the solid preparation contained in the package is sufficiently protected, and when the PTP package is used, the solid preparation can be taken out with an appropriate external force.
In particular, 1-{[(α-isobutanoyloxyethoxy) carbonyl] aminomethyl} -1-cyclohexaneacetic acid is a hydrolyzable substance, and generates acetaldehyde that causes odor by the hydrolysis reaction. Moreover, the solid preparation containing the compound is easily colored by moisture absorption. Accordingly, the package is required to have high moisture absorption and gas adsorption.
The package of the present invention can prevent generation of unpleasant odors and coloring of solid preparations by adsorbing water, acetaldehyde and the like by the adsorption layer. As a result, the preservation state of the solid preparation containing the compound can be favorably maintained.

The base material layer is preferably made of a polyamide resin or a polyvinyl chloride resin.
By using the above material as the base material layer, an appropriate rigidity can be imparted to the packaging film. As a result, when the container sheet constituting the package is formed, it can be easily formed by press working.

At this time, it is preferable that the ratio of the height of the housing portion to the diameter of the housing portion is formed with 0.335 as an upper limit.
In general, it is expected that the pinhole occurrence rate increases as the film is stretched. Therefore, when designing a storage part to be molded by press processing according to the shape or size of a pharmaceutical preparation such as a tablet or capsule to be stored, an appropriate frontage of the storage part is used to ensure the required height. In some cases, the ratio of the height of the accommodating portion to the diameter of the accommodating portion (the height of the accommodating portion / the diameter of the accommodating portion) is regulated to be equal to or less than a target value unique to each film. Moreover, in the case of a deformed tablet, it can design based on the height of the accommodating part with respect to the short diameter of a pocket frontage.
Thus, by making the ratio of the height of the storage portion and the diameter of the storage portion equal to or less than the above numerical value, the occurrence of pinholes can be prevented when the container sheet of the package is formed. Generally, when forming a container sheet by pressing a packaging body film, the larger the ratio of the height of the housing portion to the diameter of the housing portion, the larger the boundary portion between the top surface of the housing portion and the side surface of the housing portion (shoulder R Part) vicinity, a pinhole arises in the aluminum foil in a packaging body film. In particular, when the container sheet is formed by press working that does not heat the packaging film, if the ratio of the height of the container to the diameter of the container is larger than the above value, the probability of occurrence of pinholes in the container increases. However, if the value is less than or equal to the above value, the probability of occurrence of pinholes can be made substantially zero. Therefore, when the packaging body film is pressed, a pinhole is unlikely to be generated in the housing portion, so that the packaging body having excellent moisture resistance can be obtained.

Furthermore, it is preferable that the lid sheet is provided with an aluminum foil.
When the lid sheet is provided with an aluminum foil, the moisture resistance between the solid formulation container formed on the container sheet and the lid sheet can be improved. As a result, water and gas molecules in the storage portion are adsorbed by the adsorption layer provided in the storage portion formed in the container sheet, so that moisture resistance is improved.
In addition, when the lid sheet is made of aluminum foil, it is preferable that the PTP package is easily broken by an external force applied from the container sheet side, and as a result, the solid preparation in the container can be easily taken out.

The effective pore diameter of the zeolite is preferably 3 mm or more.
Since zeolite has a high adsorption rate, it can adsorb moisture quickly. Molecular sieve, which is an example of zeolite, is a porous granular material used to separate materials according to the difference in molecular size, and has a structure with uniform pores. It acts as a kind of sieve by adsorbing molecules. In the present invention, when a molecular sieve is used, the adsorption port diameter is preferably 0.3 nm to 1 nm. In general, molecular sieves having pore sizes of 0.3 nm, 0.4 nm, 0.5 nm, and 1 nm are referred to as molecular sieve 3A, molecular sieve 4A, molecular sieve 5A, and molecular sieve 13X, respectively. In the present embodiment, molecular sieve 3A or molecular sieve 4A is used as a suitable desiccant. The average particle diameter of the molecular sieve is, for example, about 10 μm.
In general, the substance adsorbed by the zeolite depends on the effective pore size of the zeolite.
If the effective pore size of the zeolite is less than 4 mm, water can be adsorbed but relatively large molecules such as carbon dioxide and acetaldehyde cannot be adsorbed sufficiently. On the other hand, when the effective pore diameter of the zeolite is 4 mm or more, relatively large molecules such as water, carbon dioxide, acetaldehyde, hydrogen sulfide, ethane, and ethanol can be adsorbed.
Therefore, when only water affects the storage state of the solid preparation, the solid preparation can be stored in a good state when the effective pore diameter of the zeolite is 3 mm or more. Furthermore, if the effective pore size of the zeolite is 4 mm or more, substances that emit odors such as hydrogen sulfide and substances that may affect the storage state of solid preparations such as ethanol are also adsorbed by the adsorption layer, which is good. The solid preparation can be stored in a safe storage state.

According to the packaging body of the present invention, the adsorption layer is provided in the packaging body film constituting the container sheet, and the base layer and the aluminum foil are further provided thereon. Therefore, the package is not only highly moisture-proof due to the aluminum foil, but also the moisture absorption is improved by adsorbing water and gas molecules in the container of the solid preparation by the adsorption layer, and appropriate rigidity is imparted by the base material layer. Is done.
As a result of imparting appropriate rigidity, the package of the present invention can be easily processed by pressing without heating, and the moldability is dramatically improved. And the yield improves with the improvement of a moldability. Furthermore, as a result of imparting appropriate rigidity, the package of the present invention can improve the storage state of the solid preparation.
In addition, by setting the ratio of the height of the storage portion to the diameter of the storage portion that stores the solid preparation to be a predetermined height or less, it is possible to prevent the occurrence of pinholes particularly in the vicinity of the storage portion.
Furthermore, moisture resistance is further improved by providing the lid sheet with an aluminum foil.
Furthermore, by setting the effective pore diameter of the zeolite contained in the adsorption layer to a predetermined value or more, not only water but also other gas molecules can be adsorbed. And the solid preparation can be stored in a good storage state.

In addition, you may arrange | position a skin layer on both surfaces of the adsorption layer 1. FIG. The material for the skin layer is not particularly limited as long as it (1) prevents the zeolite-containing layer from being exposed on the surface and directly contacts the preparation, or (2) improves the laminating property. Examples of the material for the skin layer include LDPE (low density polyethylene), LLDPE (linear low density polyethylene), PP (polypropylene), chlorinated polypropylene, saturated polyester, EAA (ethylene-acrylic acid copolymer), and EMAA.

Further, the zeolite constituting the adsorption layer 1 contains a molecular sieve, and the molecular sieve preferably has an effective pore diameter of about 3 to 10 mm. The molecular sieve selects the effective pore diameter according to the size of the object to be adsorbed. In particular, when the effective pore size is 4 mm or more, not only water but also gas molecules such as carbon dioxide, acetaldehyde, hydrogen sulfide, ethane, and ethanol can be adsorbed. In addition, when the solid preparation 8 is decomposed, a substance that causes odors such as acetaldehyde and hydrogen sulfide is also preferred because it is adsorbed by the adsorption layer 1.

In addition, artificial zeolite is obtained by forming a substance similar in nature to natural zeolite from various substances by an industrial method. Therefore, the adsorptivity and ion exchange properties are improved. Therefore, the zeolite material constituting the adsorption layer 1 may be appropriately selected according to the substance to be adsorbed.

The base material layer 2 is a layer made of a resin bonded to the adsorption layer 1 and mainly imparts appropriate rigidity and moldability to the packaging body film F1. As a material of the base material layer 2, at least one selected from polyvinyl chloride, polypropylene, polyvinylidene chloride, polyamide such as nylon (registered trademark), and the like, or a combination thereof can be used. Among these, polyamides such as nylon (registered trademark) and PVC (polyvinyl chloride) are preferable, and PVC (polyvinyl chloride) having an appropriate elongation property is particularly preferable. When polyvinyl chloride is selected, the moldability and rigidity of the packaging body film F1 can be kept good, and the occurrence of pinholes can be prevented when molding the packaging body P to be described later by pressing. .
The thickness of the base material layer 2 is preferably 15 to 25 μm in order to ensure the rigidity of the packaging body film F1 and to maintain good moldability.

The aluminum foil 3 may be a pure aluminum foil or an aluminum alloy foil. Further, a pure aluminum foil coated with a resin such as PP (polypropylene) may be used.
In addition, the thickness of the aluminum foil 3 is preferably 30 to 60 μm in order to maintain good moldability, maintain moisture resistance and light-shielding properties of the container, and provide appropriate rigidity and moldability.

The barrier layer 4 is formed from a film-like material that can be sealed. Examples of the material constituting the barrier layer 4 include HDPE (high density polyethylene), MDPE (medium density polyethylene), LDPE (low density polyethylene), polyvinylidene chloride, polychlorotrifluoroethylene, PP (polypropylene), polyethylene terephthalate, And at least one selected from polyamide such as nylon (registered trademark), etc., or a combination thereof. Among these, it is preferable to select polyamide such as nylon (registered trademark) because the moldability is improved. The barrier layer 4 is preferably 5 to 30 μm in order to maintain sufficient hermeticity and appropriate moldability.

Further, an adhesive layer (not shown) may be provided between the adsorption layer 1, the base material layer 2, the aluminum foil 3, and the barrier layer 4, respectively. Examples of the adhesive layer (not shown) include urethane-based adhesive, HDPE (high density polyethylene), MDPE (medium density polyethylene), LDPE (low density polyethylene), polypropylene, chlorinated polypropylene, saturated polyester, EAA (ethylene- Acrylic acid copolymer), EMAA (ethylene-methacrylic acid copolymer), EEA (ethylene-ethyl acrylate copolymer), EMAC (ethylene-methyl acrylate copolymer), ionomer, carboxylic acid-modified polyethylene, carboxylic acid-modified At least one selected from polypropylene, carboxylic acid-modified EVA, PVC (polyvinyl chloride), polystyrene and the like, or a combination thereof can be used. The thickness of the adhesive layer (not shown) is preferably about 10 μm.

Moreover, each layer of the said adsorption layer 1, the base material layer 2, the aluminum foil 3, and the barrier layer 4 can be bonded together by a well-known method, and methods, such as extrusion lamination, dry lamination, wet lamination, thermal lamination, sand lamination, etc. Can be pasted together.

As described above, the packaging body film F1 composed of the adsorption layer 1, the base material layer 2, the aluminum foil 3, and the barrier layer 4 only needs to have appropriate rigidity to form the packaging body P described later. Accordingly, the total thickness of each layer, that is, the thickness of the packaging body film F1 is preferably about 120 to 200 μm.

(Structure of package P)
As shown in FIG. 2, the packaging body P according to an embodiment of the present invention is formed by a container sheet 6 formed by the packaging film F1 and a lid sheet 7 having airtightness. The solid preparation 8 is packaged inside the container 5. 2 exaggerates the thickness of the container sheet 6 for the sake of explanation.

The container sheet 6 is formed of a package film F1 in which an adsorption layer 1, at least one base layer 2, an aluminum foil 3, and a barrier layer 4 are laminated. And the container sheet | seat 6 is formed with the one or more concave accommodating parts 5 which accommodate the solid formulation 8 using the packaging body film F1.

The container sheet 6 has a configuration in which the adsorption layer 1 is disposed on the surface on the side where the solid preparation 8 is accommodated, as shown in FIG. With this configuration, water contained in the container 5 and the solid preparation 8 or a gas generated when the medicine contained in the solid preparation 8 reacts with water is absorbed by the adsorption layer 1. Therefore, the solid preparation 8 accommodated in the accommodating part 5 can be preserve | saved in a suitable preservation | save state, without a component deteriorating.

The container sheet 6 having the above-described configuration has one or more accommodating portions 5 formed on the packaging film F1 by a technique such as press molding. In addition, the shape of the accommodating part 5 is suitably designed depending on the shape of the solid preparation 8 accommodated inside. Although the method of press molding is not particularly limited, a known method such as stretch forming or deep drawing is used.

The lid material sheet 7 is in close contact with the surface of the container sheet 6 on which the adsorption layer 1 is provided, and seals the inside of the storage unit 5 in which the solid preparation 8 is stored.
If the adhesion between the container sheet 6 and the lid sheet 7 is low, a heat-sealable resin layer (not shown) may be provided on the surface of the adsorption layer 1 facing the lid sheet 7. good. As a material for the heat-sealable resin layer, a material equivalent to the adhesive layer (not shown) can be used.

The lid material sheet 7 is formed from a film-like material that can be sealed and has a property of preventing the inflow and outflow of gas such as water vapor. Examples of the material constituting the lid sheet 7 include aluminum, high density polyethylene, medium density polyethylene, low density polyethylene, polyvinylidene chloride, polychlorotrifluoroethylene, and polyamide such as polypropylene and nylon (registered trademark). At least one selected, or a combination thereof can be used. Among these, aluminum is preferable because moisture resistance and light shielding properties of the container are improved. When aluminum is used, it is preferable that an adhesive be applied to the surface facing the container sheet 6. As the adhesive used at this time, ethylene-vinyl acetate copolymer, polyvinylidene chloride, vinyl chloride-vinyl acetate copolymer, chlorinated polypropylene, and the like can be used. Aluminum may be either pure aluminum or an aluminum alloy.

(Test Example 1: Stiffness test of container sheet 6)
When evaluating the strength of the container 5 of the container sheet 6 when the base material layer 2 is PA or PVC (hardness to crush against external force), all had sufficient strength as a package, Compared with the case of using PA (Example 1), it was shown that the case of using PVC (Example 2) has higher strength of the accommodating portion 5 and is less likely to be crushed. The results are shown in Table 1 below.

From the above results, it was shown that when PVC is used as the base material layer 2, the strength of the housing portion 5 is improved about twice as compared with the case where PA is used. The structure of the packaging body film F1 which comprises the container sheet 6 of Example 1 and Example 2 is shown below.

(Test Example 2: Formability test of container sheet 6)
In general, on the condition that the diameter (pocket diameter) of the accommodating portion 5 is constant, the height of the accommodating portion 5 is related to a pinhole generated in a portion of the packaging film F1 where the accommodating portion 5 is formed, As the ratio of the height of the housing part 5 to the pocket diameter (the ratio of the height of the housing part 5 / the ratio of the pocket diameter) increases, the probability of pinholes increases and the ratio of the height of the housing part 5 to the pocket diameter decreases. The probability of pinhole occurrence decreases. About the packaging body film F1 (container sheet 6) of Example 3, the probability of occurrence of pinholes was evaluated by visually confirming light transmission. The results are shown in Table 2. In addition, the structure of the packaging body film F1 of Example 3 is mentioned later.

Table 2 shows a case in which a plurality of accommodating portions 5 are formed at different heights, and the light transmittance in each accommodating portion 5 is visually confirmed. The pockets where light transmission was confirmed were counted as having pinholes, and the pinhole generation rate relative to the whole was shown. The pocket diameter of the mold used for molding is 15 mm.

Measured pinhole occurrence rate of each accommodating part 5 was found to be 0% when the height of the accommodating part 5 was 5.032 mm or less. Therefore, from the above test results, when the diameter of the accommodating part 5 is 15 mm, it is preferable that the height of the accommodating part 5 is 5.032 mm or less because no pinhole is observed. The “height” of the container 5 is the distance from the flat surface of the barrier layer 4 of the container sheet 6 (that is, the surface where the container 5 is not formed) to the uppermost surface (top surface) of the pocket ( It refers to H) in FIG. Further, the “diameter (pocket diameter) of the accommodating portion 5” refers to the inner diameter of the opening of the accommodating portion 5 (that is, L in FIG. 2). At this time, the opening part of the accommodating part 5 does not necessarily need to be a perfect circle. For example, when the opening of the housing part 5 is rectangular or elliptical, the “diameter of the housing part 5 (pocket diameter)” refers to the inner diameter in the longitudinal direction.

Therefore, it was shown that the packaging body film F1 including one or more kinds of the base material layers 2 is suitable without generating cracks and pinholes when the packaging body P is formed. Moreover, when the diameter of the accommodating part 5 was 15 mm, when the height of the accommodating part 5 shall be 5.032 mm or less, it was shown that there is no generation | occurrence | production of a pinhole and it is suitable.
When the package P that does not include the base material layer 2 was molded, cracks occurred in the vicinity of the top surface of the housing 5.
Depending on the shape and size of the solid preparation to be accommodated, it is possible to increase the diameter of the accommodating part 5 so that the height of the accommodating part 5 is 5.0 mm or more. In this case, it is preferable that the ratio of the height of the housing part 5 to the diameter of the housing part 5 is formed with an upper limit of 0.335 based on the test result.
In addition, the height of the accommodating part 5 will not be specifically limited if it selects suitably by the shape or magnitude | size of pharmaceutical formulations, such as a tablet or a capsule. Specifically, for example, (i) when the tablet is a deformed tablet having a major axis of 15.1 mm × minor axis of 8.0 mm × height of 5.7 mm, the size of the frontage (the opening of the storage unit 5) is the major axis of 24.0 mm × short (Ii) If the tablet has a circular shape with a diameter of 9.6 mm and a height of 5.1 mm, the front portion is 22.0 mm in diameter and 6.3 mm in height (H / L = 0.263). Examples thereof include a housing portion (H / L = 0.281) having a diameter of 19.6 mm and a height of 5.5 mm.

((Example 1))
The solid body 8 obtained in the above formulation example is sealed by adhering and sealing the container sheet 6 formed by the packaging film F1 having the following configuration and the lid sheet 7 made of aluminum. Obtained. In addition, since the structure of the packaging body film F1 which comprises the sheet | seat 6 for containers of Example 1 is the same as that of Example 1 mentioned above, the description is abbreviate | omitted.

((Comparative Example 1))
The solid preparation 8 obtained in the above preparation example is sealed by adhering the container sheet 6 formed by the packaging film F1 having the following configuration without the adsorption layer 1 and the lid sheet 7 made of aluminum. Thus, a package P was obtained.
[Configuration of packaging film]
Adsorption layer 1: None Base material layer 2: PVC (polyvinyl chloride) (thickness: 60 μm)
Aluminum foil 3: Pure aluminum foil (thickness: 45 μm)
Barrier layer 4: Stretched polyamide resin (thickness: 25 μm)

((Comparative Example 2))
The solid body 8 obtained in the above formulation example is sealed by adhering and sealing the container sheet 6 formed by the packaging film F1 having the following configuration and the lid sheet 7 made of aluminum. Obtained.
[Configuration of packaging film]
Adsorption layer 1: low density polyethylene containing calcium oxide (calcium oxide amount relative to polyethylene: 30 wt%) (thickness: 40 μm)
Base material layer 2: EAA (ethylene-acrylic acid copolymer) (thickness: 10 μm)
Aluminum foil 3: Pure aluminum foil (thickness: 45 μm)
Barrier layer 4: Stretched polyamide resin (thickness: 25 μm)

In the above Example 1, Comparative Example 1 and Comparative Example 2, in order to examine the stabilizing effect of the active ingredient contained in the package P with respect to the solid preparation 8, a relative appearance comparison was performed by color difference measurement. 3 to 6 are graphs showing the color difference measurement results at each temperature. In addition, ΔE in the graph represents the solid preparation 8 immediately after production and the solid preparation 8 after storage at a predetermined temperature (FIG. 3: 50 ° C., FIG. 4: 40 ° C., FIG. 5: 30 ° C., FIG. 6: 25 ° C.). The color difference ΔE is measured with a color difference meter.

In the present specification, “coloring” means that a color other than white is exhibited in appearance.
The following tests were performed using the package P of the solid preparation 8 obtained in Example 1 and Comparative Examples 1 and 2 as a sample.

The solid preparation 8 stored in a cold place after production at a predetermined temperature was used as a control sample, and the samples of Example 1 and Comparative Examples 1 and 2 were 50 ° C., 40 ° C., 30 ° C., and 25 ° C., respectively (relative humidity). 75%) was used as a sample after storage. The solid preparation 8 packaged in each package P was taken out, and the appearance was evaluated by measuring the color difference ΔE between the control sample and the sample after storage with a color difference meter (CM-3500d, manufactured by Konica Minolta).

FIG. 3 shows that when stored at 50 ° C., Example 1 has a lower degree of coloring of solid preparation 8 than Comparative Examples 1 and 2. Compared to Comparative Example 1 that does not include the adsorption layer 1, the color difference ΔE of Example 1 is about one third after 3 days, and the packaging P of Example 1 colored the solid preparation 8. Is greatly suppressed. Furthermore, it was shown that Example 1 can suppress coloring of the solid preparation 8 rather than the package P of Comparative Example 2 containing calcium oxide in the adsorption layer 1.

In FIG. 4, Example 1 showed that the degree of coloring of the solid preparation 8 was smaller than that of Comparative Examples 1 and 2 even when stored at 40 ° C. When the adsorption layer 1 is not provided as in Comparative Example 1, ΔE showed a high value of about 32 after one month, but Comparative Example 2 containing calcium oxide in the adsorption layer 1 and Example 1 Was about 1.
Further, after 3 months of extending the storage period, ΔE of Example 1 was about 12, but ΔE of Comparative Example 2 was about 22, and the difference in ΔE was remarkable after long-term storage. It was. Therefore, it was shown by this color difference measurement that the package P of the present invention effectively suppresses coloring.

FIG. 5 shows that Example 1 and Comparative Example 1 are slightly different when stored at 30 ° C., but ΔE is smaller in Example 1. In Example 1, when the storage temperature is 30 ° C., ΔE is always less than 1 throughout the storage period of 6 months, the degree of coloring is extremely small, and it is confirmed that it is suitable for storage of the solid preparation 8 It was done.

In FIG. 6, when stored at 25 ° C., after 6 months, Example 1 shows that ΔE is held at a small value as compared with Comparative Example 2 in which calcium oxide is contained in the adsorption layer 1. ing. Even in the case of 25 ° C., it was confirmed that the degree of coloring remained small when 6 months passed.

Therefore, from the result of the above color difference measurement, by using the package P including the adsorption layer 1 containing zeolite on the side where the solid formulation 8 is accommodated, like the package P of the present invention, the solid formulation 8 It became clear that coloring was effectively prevented.

In the color difference measurement, the packaging body P of Example 1 (the thickness of the adsorption layer 1 is 50 μm) was evaluated, but the packaging body P of Example 2 described above (however, the thickness of the adsorption layer 1 was set to 130 μm). When the color difference measurement of the layer structure other than the adsorption layer 1 is the same as that of the above-described Example 2, the both showed substantially the same color difference ΔE.

The above results are not limited to the configuration of preventing intrusion of water or the like from the outside as in Comparative Example 1, but are effective by absorbing the water contained in the housing portion 5 at the time of packaging by the adsorption layer 1. It shows that the ingredients can be stabilized.

Furthermore, from the above results, in the configuration of the package P, when the adsorption layer 1 containing zeolite is not provided, it is difficult to stabilize the active ingredient sufficiently depending on the storage temperature. 6, it was found that the active ingredient can be stabilized and the progress of hydrolysis can be effectively suppressed by constituting the adsorption layer 1 containing zeolite in the surface on the side containing the solid preparation 8. .
This result is presumed to be due to the fact that zeolite has an ability to adsorb not only water but also other gas molecules (aldehyde, CO _2, etc.) as compared with calcium oxide that adsorbs only water.

(Test Example 4: Dissolution rate of orally disintegrating tablets)
Using the package P of Example 1 and Comparative Examples 1 and 2, the effect of the package P of the present invention on the orally disintegrating tablet containing a water-soluble drug component was evaluated.

After obtaining particles in which crystalline cellulose (grains) was coated with solifenacin succinate, mannitol (excipient) was added to the particles, and an aqueous maltose (binder) solution was sprayed to coat and granulate. After mixing magnesium stearate (lubricant) into the granulated product, tablets were produced using a rotary tableting machine. Next, the tablets were humidified and dried using a humidifying dryer to obtain 150 mg of orally disintegrating tablets per tablet.

Orally disintegrating tablets are packaged by the package P of Example 1 and Comparative Examples 1 and 2 for 3 months (Example 1-1, Comparative Example 1-1, Comparative Example 2-1) and 6 months, respectively. (Example 1-2, Comparative Example 1-2) Stored (storage conditions: 40 ° C., relative humidity 75%, dark place).
FIG. 7 shows the degree of dissolution of the orally disintegrating tablet after a predetermined storage period (measured after 0, 30, 45 minutes). The dissolution test was carried out at 900 rpm with a paddle method using 900 mL of pH 6.8 phosphate buffer.

As a result, in the sample with a storage period of 3 months, a significant difference was observed in the dissolution after 30 minutes. The dissolution rate was 99% in Example 1-1, 81% in Comparative Example 1-1, and 98% in Comparative Example 2-1, and the orally disintegrating tablet packaged in the package P of Example 1 was adsorbed. As with the package P of Comparative Example 2-1, in which layer 1 contains calcium oxide, it was shown that high elution was maintained.

Moreover, a large difference was observed in the elution degree after 30 minutes even in the sample with a storage period of 6 months. In Example 1-2, the dissolution rate was 92%, and in Comparative Example 1-2, 82%. It was shown that the orally disintegrating tablet packaged in the package P of Example 1 retains high dissolution properties. It was.

Orally disintegrating tablets are tablets that disintegrate in the oral cavity with saliva or a small amount of water, and are required to dissolve (disintegrate) rapidly in the oral cavity. In general, when the orally disintegrating tablet is not preferably stored, the dissolution is delayed and it is difficult to dissolve (disintegrate) in a short time. On the other hand, it was shown by the said evaluation that the dissolution delay of an orally disintegrating tablet was suppressed by the package P of this invention, and it has high dissolution property in a short time. This result is presumed that the adsorption layer 1 provided in the package P of the present invention effectively adsorbs water and the like, and thus contributes to the stabilization of the orally disintegrating tablet of the adsorption layer 1.
