Definitions
- the present invention relates to a method for producing starch granules used as an excipient for orally disintegrating tablets, and an orally disintegrating tablet in which the starch granules are used as an excipient.
- Starch ... It has the meaning as a substance name and the meaning of the aggregate of starch particles.
- ⁇ -starch Starch in a crystalline state that gives an interference ring with natural X-rays (cf. “Chemical Dictionary 1” (Akira 37-7-31), Kyoritsu Shuppan, p428).
- Glue solution A starch aqueous dispersion obtained by heat-dispersing the ⁇ starch in a water dispersion medium until a uniform phase is formed at a temperature equal to or higher than the gelatinization temperature.
- ⁇ starch ( ⁇ -modified starch, ⁇ -type starch): starch in an amorphous state that does not show an interference ring by X-rays. It is obtained by heat treatment at a temperature equal to or higher than the gelatinization temperature in the presence of water (moisture) or treatment with a swelling reagent (Source: same as above).
- the orally disintegrating tablet has an orally disintegrating property that disintegrates immediately in the oral cavity, and at the same time, there is no problem in tablet strength (hereinafter referred to as “hardness”) from the manufacturing process to the packaging process, shipping, and subsequent handling. It is necessary to have Since this orally disintegrating property and hardness are usually contradictory properties, various additives, special production equipment, and the like are required for tableting of orally disintegrating tablets. And the tableting cost of an orally disintegrating tablet is borne by consumers, patients, and the government finances. Accordingly, there is a demand for the emergence of a technique that can easily form an orally disintegrating tablet using an inexpensive raw material.
- Patent Document 1 proposes an orally disintegrating tablet having the following constitution (see claim 1).
- the orally disintegrating tablet having the above-described structure needs to be added with lactose and / or D-mannitol which lowers moldability in order to ensure the disintegration property in the oral cavity when the tablet is formed (the same document, claims 8 and 10). 14, paragraph 0021).
- a water-soluble polymer such as crystalline cellulose (for example, hydroxypropylcellulose) in order to impart hardness (the same document, claim 11, paragraph 0024).
- the orally disintegrating tablet described in Patent Document 1 uses a relatively inexpensive starch.
- auxiliary excipients such as saccharides and crystalline cellulose need to be added in addition to starch. For this reason, it cannot necessarily be said that the raw material cost is low and the tableting cost is low.
- Patent Document 2 describes a method for producing starch particles having the following constitution (claim 3).
- starch particles are not intended for the disintegration property of the tablet in the oral cavity, and as in the case of Patent Document 1, sugars such as lactose and syrup which are auxiliary excipients are added (Patent Document 2).
- Patent Document 2 sugars such as lactose and syrup which are auxiliary excipients are added (Patent Document 2).
- Reference Examples 1 to 4) have the same problems as described above.
- an object (issue) of the present invention is to produce a starch granule that can impart sufficient oral disintegration and hardness to a tablet when used as an excipient in tableting of an orally disintegrating tablet. It is to provide a method.
- each particle of ⁇ starch is brought into contact with the paste liquid and granulated by air fluidized bed, and further gelatinized of ⁇ starch.
- the fluidized bed is dried at a temperature higher than that.
- Tablets obtained by tableting using the starch granules produced as described above as excipients have good oral disintegration properties despite their high hardness (see Table 2). That is, a tablet having sufficient orally disintegrating property and hardness can be obtained without adding an auxiliary excipient.
- the starch granule prepared by the production method of the present invention is a particle bond in which an infinite number of ⁇ -starch particles are partially bonded using ⁇ -starch as a binder in a state in which each particle shape is maintained. Is the body. That is, ⁇ starch as a binder efficiently contributes to binding between ⁇ particles.
- the tablet compressed (molded) with the granule of the present invention has a predetermined hardness until it touches saliva in the oral cavity. And when saliva is touched in the oral cavity, since the ratio of ⁇ starch is small, it quickly dissolves and disintegrates in the oral cavity.
- the degree of compression is high, the fluidity is good (Examples 1 and 2 and Reference Examples 1 and 2 in Table 2).
- the starch granule (particle combination) of the present invention also has good moldability (tabletability) and contributes to the improvement of tablet hardness.
- Patent Document 2 the corresponding Example 2 in Patent Document 2 is different from the method of the present invention in the fluidized bed system, the spray speed and the total spray amount as follows.
- FIG. It is an electron micrograph (magnification 2000 times) of normal corn starch. It is an electron micrograph (magnification 2000 times) of the surface of the granule of an Example of this application. It is an electron micrograph (500-times multiplication factor) of the whole image of the granule of an Example of this application. It is a graph which shows the relationship between the swelling rate which is the test result implemented in various starch, and an oral disintegration time.
- Oral disintegrating tablets It means a tablet that disintegrates within 40 s, preferably within 30 s, substantially by saliva alone in the oral cavity without ingesting water to take the tablet.
- Oral disintegration is determined by the oral disintegration time.
- the oral disintegration time is a value when the movement of the tongue or the like is made natural when the tablet is included in the oral cavity.
- the oral disintegration time is determined by including the measurement tablet without moisture in the mouth of a healthy adult male and measuring the time until the tablet is completely disintegrated with saliva alone. be able to. At this time, it is not necessary to suppress natural movement of the tongue. (Quoted from Patent Document 1, paragraph 0012).
- glucoamylase 1 g is dissolved in 100 mL of water, and the supernatant is used as the enzyme solution.
- the reaction is terminated by adding 10 mL of 25 mmol / L HCl to 0.5 mL of each reaction solution. Collect 0.5 mL of the supernatant and add 0.5 mL of water and 1.0 mL of Somogyi reagent. The liquid is heated in boiling water for 10 minutes and then cooled. 1 mL of Nelson reagent is added, and after 3 minutes, the total volume is made up to 10 mL with purified water, and the absorbance at a wavelength of 660 nm is measured. The degree of alpha was determined by the following formula.
- ⁇ "Particle size" Range classified by sieving. That is, pile up multiple stages of sieves with different openings so that the large sieve comes to the upper stage side, put the powder to be measured on the uppermost stage sieve, classify by applying vibrations manually or by machine, and open the openings on the sieve The lower limit value and the opening under the sieve are taken as the upper limit value.
- Glue concentration It is% concentration (wt%) with respect to the mass of water of ⁇ starch mass (as water 12.5%) used for paste liquid preparation.
- Tablet hardness It means the hardness of tablets formed by tableting.
- the hardness of the tablet is represented by the force (unit: N) required for crushing the tablet, and the larger the numerical value, the greater the breaking strength of the tablet.
- the hardness was measured using “Portable Checker PC-30” (A load cell type tablet hardness tester manufactured by Okada Seiko Co., Ltd.).
- Compressibility 100 ⁇ (hardened bulk density ⁇ loose bulk density) / hardened bulk density
- Compressibility 100 ⁇ (hardened bulk density ⁇ loose bulk density) / hardened bulk density
- the bulk density was measured with “Powder Tester PTX” (Hosokawa Micron).
- the starch granule production method of the present invention is basically characterized by spraying paste liquid while fluidizing ⁇ starch (raw material starch) using an air fluidized bed, and each particle of the ⁇ starch. Is contacted with the paste liquid, and fluidized bed granulation in which the dispersoid ( ⁇ starch) in the paste liquid is adhered to the particles of the ⁇ starch, and further fluidized bed drying is performed at a temperature higher than that capable of being gelatinized.
- the type of raw starch used for ⁇ starch (raw starch) and paste liquid is not particularly limited, but it is desirable to select from the group consisting of corn starch, wheat starch, potato starch, rice starch, and tapioca starch. . This is because these starches are versatile and easily available.
- the air temperature of the air fluidized bed is usually set in the range of 60 to 90 ° C., preferably 65 to 80 ° C. If the air temperature is too high, it may be accompanied by alteration of ⁇ starch, which is not desirable.
- ⁇ -starch is appropriately selected from an average particle diameter (median diameter) of 1 to 100 ⁇ m, preferably 5 to 50 ⁇ m.
- the preparation method of the paste liquid can be performed by a conventional method. For example, it is prepared by dispersing and stirring about 3% of ⁇ starch (raw starch) in room temperature water (not limited to purified water) and heating to 60 ° C. or higher.
- ⁇ starch raw starch
- room temperature water not limited to purified water
- the starch concentration of the paste is 1 to 6%, preferably 1 to 3.5%, more preferably 2.5 to 3.5%. If the starch concentration is too high, spraying becomes difficult, and if the starch concentration is too low, the time for obtaining granules of a predetermined particle size becomes longer and the drying time becomes longer and the productivity is lowered.
- the spraying speed of the paste is such that when the paste concentration is 1 to 6%, the paste is 0.2 to 5 parts / minute, preferably 0.5 to 3 parts / minute with respect to 100 parts of the ⁇ starch.
- the amount is such that And the granulation of powder gradually decreases by granulation.
- the total amount of paste sprayed is 30 to 70 parts, preferably 50 to 65 parts per 100 parts of ⁇ starch, although it varies depending on the spraying and fluidizing conditions when the same concentration of the paste liquid is 1 to 6%. .
- the paste liquid is solidified due to a decrease in temperature, there is a concern about troubles in the solution supply path and spray state. For this reason, the paste liquid is usually maintained at an appropriate temperature within the range of 60 ° C. or higher, desirably 60 to 90 ° C., more desirably 75 to 85 ° C.
- the drying temperature air temperature of the fluidized bed
- the drying temperature is equal to or higher than the gelatinization temperature of ⁇ -starch, and specifically varies depending on the type of ⁇ -starch (raw starch), but is usually 80 to 110 ° C., preferably 90 to Set to 110 ° C.
- the drying temperature is set to 10 to 20 ° C. higher than the air temperature of the air fluidized bed in order to promote the gelatinization of the granules and increase the drying efficiency.
- the moisture (dry basis) of the granular starch after drying is about 6 to 12%, preferably about 8 to 11% (see Table 2).
- the granular starch of Example 1 produced in this way has a degree of compression of 20-30%. Usually, the degree of compression of 20 to 30% is generally poor in fluidity (the lower the degree of compression, the better the fluidity). However, as shown in Table 2, the repose angle is as small as about 5 ° as compared with the pregelatinized corn starch of Comparative Example 2 having the same degree of compression, and the fluidity is sufficiently secured. Since the starch granule produced by the stirring granulation method of Comparative Example 1 also has a small angle of repose, it is generally possible to improve fluidity by granulation. However, as shown in Comparative Example 1, the granules granulated by the agitation granulation method clearly show different properties when made into tablets, and it is difficult to obtain an orally disintegrating tablet with appropriate hardness.
- the oral disintegration property and hardness are substantially reduced even if one or both of other orally disintegrating agents and hardness-imparting agents are not contained. A good balance can be achieved.
- the pregelatinization degree of the starch granule is appropriately set in the range of 1 to 15%, desirably 3 to 12%, depending on the required characteristics.
- the degree of alpha conversion is high, the ratio of alpha starch as a binder is high, so that tablets with high hardness are easily obtained, but the disintegration property in the oral cavity decreases.
- the degree of pregelatinization is low, the ratio of alpha starch as a binder is low, so that the disintegration property in the oral cavity is improved, but it becomes difficult to obtain a tablet with high hardness.
- the degree of pregelatinization is increased.
- a device having a structure as shown in FIG. 2 can be suitably used as a fluidized bed granulation / drying apparatus which is an air fluidized bed.
- a stationary dispersion plate (directional screen) 11 is provided, and fluidized air is fed from below to generate a swirling air flow to form a fluidized bed of input particles.
- the fluidized bed container 13 includes a spray nozzle 15 that faces the dispersion plate 11 and is connected to the paste liquid pipe 14, and further includes a bag filter 17 on the upper side thereof. Note that the product (starch granules) after drying can be recovered in the recovery tank 21 by air swirling flow by switching the switching valve 19.
- a fluidized bed granulating / drying apparatus for example, “WSG series”: trade name of Powrec Co., Ltd.
- WSG series trade name of Powrec Co., Ltd.
- the starch granules thus produced can be used as raw materials for tablets as they are, excluding foreign substances.
- the particles having an excessively small or excessively large particle diameter are classified and removed as appropriate in order to stably obtain required oral disintegration properties and hardness. That is, it is conceivable that when the particle size is small, the proportion of ⁇ starch is too small, and when the particle size is large, the proportion of ⁇ starch tends to be too large, which affects the disintegration in the oral cavity.
- the starch granules granulated in this way are mixed with medicinal ingredients and tableted.
- the tableting method is not particularly limited, and compression molding (briqueting roll, tableting), extrusion molding (screw, rotating porous die) and the like can be suitably used. Since the ratio of the medicinal component to the starch granule is small, it is considered that the medicinal component does not have a great influence on the evaluation of the tablet containing only the starch granule, and the tablet containing only the starch granule is evaluated.
- the starch granules granulated by the method of the present invention can be disintegrated in the oral cavity even by a direct compression method without adding additives such as other oral disintegration imparting agents and hardness imparting agents. And having sufficient hardness (breaking strength) can be obtained.
- the tablet to be molded according to the present invention has an oral disintegration time of 40 s or less, 30 s or less, and a hardness of 55 N or more, further 70 N or more.
- the fluidized bed granulating / drying apparatus used in the above-described configuration shown in FIG. 2 was an air fluidized bed granulating apparatus having specifications of an input capacity: 12 L, a fluid dispersion plate diameter d: 230 mm, and a nozzle height h: 600 mm. .
- the paste was prepared as follows and kept warm at 60 ° C. or higher.
- corn starch an in-house product (hereinafter simply referred to as “corn starch”) having the characteristics described in the column of Comparative Example 1 in Table 2 was used.
- the paste solution was stirred until the corn starch ( ⁇ -starch) was added to purified water at room temperature, heated to 90 ° C., and visually transparent (a uniform phase was formed).
- the above 3% paste solution was added at 83 g / min for the first 4 minutes (0 to 4 min), 83 g / min for the next 5 minutes (5 to 9 min), and 75 g / min for the next 31 minutes (10 to 40 min). Spraying was performed at each spray rate of min, and fluidized bed granulation (aggregation) was performed.
- the main conditions are shown in Table 1.
- the water content of the obtained starch granules was 7.0% (see Table 2).
- the numerical values in the lower brackets in Table 1 are for 100 parts of the raw material (the same applies to Example 2 and Comparative Example 1).
- Example 2 In Example 1, the “WSG-30” (capacity: 100 L) was used in place of the swirling fluidized bed granulator / dryer, and the amount of treatment was scaled up (5 times).
- Corn starch (25 kg) was put into a fluidized bed container, and 85 ° C. air was blown in from the bottom of the dispersion plate at an air volume of 10 m 3 / min to form and maintain a fluidized bed of the charged starch for 50 minutes.
- a 3% paste liquid was sprayed while adjusting the spray rate within a range of 300 to 500 g / min to perform fluidized bed granulation (aggregation).
- the main conditions are shown in Table 1.
- the water content of the obtained starch granules was 8.4% (see Table 2).
- Example 1 In Example 1, the stirring granulation apparatus shown in FIG. 3 was used, and stirring granulation was performed by dropping 3% of the paste-like starch dispersion at the indicated charging speed under the conditions shown in Table 1. . The granulated product is subjected to vibration fluidized bed drying under the condition of 90 ° C. ⁇ 30 min using a vibration fluidized dryer (“VUA-20” manufactured by Chuo Kako Co., Ltd.) to obtain the granular starch of Comparative Example 1. It was.

- starch granules of Example 1 and Comparative Example 1 above starch granules (100 to 180 ⁇ m) that do not pass through 100 ⁇ m but pass through 180 ⁇ m are sieved and collected to obtain tablet materials.
- Example 1 has a higher ⁇ degree and a slight but low angle of repose and good fluidity. It can be seen that the angle of repose is 10 ° or more lower than that of corn starch. That is, in the present invention, as shown in Examples 1 and 2, it was confirmed that an angle of repose (injection method) of 30 to 40 ° was obtained in a compression range of 20 to 30%.
- Example 1 although the degree of compression is higher than that of the pregelatinized starch, it can be seen that the angle of repose is clearly lower than that of the pregelatinized starch and the fluidity is excellent.
