Definitions
- the present invention relates to a method for producing a preparation produced using acetaminophen having a predetermined particle size distribution described below (hereinafter sometimes referred to as “the present acetaminophen”).
- compositions are manufactured through various preparation processes, and the most suitable manufacturing method is selected in consideration of various factors so that the functions of each preparation can be performed well. It is necessary to consider conditions.
- the preparation method for tablets is dry direct compression, dry granulation (dry roller compactor, roll granulator, etc.), wet granulation (spray granulation, stirring granulation, Extrusion granulation method, fluidized bed granulation method, etc.).
- the dry roller compactor method of the dry granulation method is a method in which an additive is added to a drug and compressed into a flake shape, then crushed and sized, classified, and the fine powder is recompressed and compressed into tablets. .
- the amount of powder scattering is large at the time of pulverization and sizing, the yield is poor, and the tablet hardness tends to be low because there is a step of compression once (Japanese Patent Publication No. 2010-506540).
- the agitation granulation method is a method in which a drug and an additive are charged in a granulation container and mixed by rotation of a stirring blade, and a binder solution is dropped or sprayed thereon to obtain an appropriate wet state. It is a method of granulating.
- the dispersion of the binder solution tends to be heterogeneous, resulting in a partially hard granulated product, slightly more powder that remains ungranulated, and a slight difficulty in content uniformity. For this reason, since it is necessary to wet crush and size and dry, the number of processes increases, and tablet hardness tends to decrease.
- the dry direct tableting method (also referred to as dry direct compression method) is the simplest method in which a drug and an additive are mixed in powder form and tableted.
- the dry direct compression method includes a method in which the additive is liquefied in advance and dried for direct compression with a spray drier, etc., and the resulting powder is mixed with a drug powder and compressed into tablets.
- a wet method is used for the treatment, and the number of steps is large.
- the dry direct compression method does not produce granules, so it has the advantages of having the fewest number of formulation steps, reducing the production cost, and increasing the production speed, but mixing compared to dry granulation methods and wet granulation methods to produce granules Due to the low fluidity of the powder, there are disadvantages such as a large variation in mass and a problem in compression moldability. Therefore, the dry direct hitting method was widely used in Europe and the United States when the particle size of drugs and additives before the 1970s was relatively large and there were few problems of secondary aggregation. However, in recent years, since drugs in recent years have become increasingly insoluble, they are pulverized by pin mills, jet mills, etc., and secondary agglomeration is likely to occur, and there is a problem in content uniformity. No longer adopted.
- the fluidized bed granulation method of the wet granulation method is generally used most widely (Japanese Patent Laid-Open No. 2013-216610, Japanese Patent Publication No. 2015-63521).
- a drug and an additive are usually charged into a fluidized bed granulator and fluidized, and a binder solution or a binder solution in which a drug is dissolved or suspended is sprayed.
- This method is excellent in content uniformity, has a high yield, and a granulated material suitable for tableting can be obtained.
- air classification may result in impaired content uniformity, and skill in the operation technique is required. It is done.
- Acetaminophen is an antipyretic analgesic that has been widely used since ancient times, and is a highly safe drug that is administered not only to adults but also to children.
- acetaminophen is used as an acetaminophen for adults with a total daily dose of 4000 mg, and a dose of 300 to 1000 mg at a dosage interval of 4 to 4 times. It is supposed to be administered orally after 6 hours.
- acetaminophen tablets include 500 mg tablets, 300 mg tablets and 200 mg tablets according to the amount of active ingredient.
- the tablet Since the content of the drug itself is such a high dose, the tablet is relatively large, and since sustained-release tablets with long-lasting effects are not sold, it is necessary to take several times a day. Due to the current situation, doctors and patients in the medical field have a smaller tablet size for better quality of life and compliance, more preferably twice a day in the morning and evening. There is a demand for development of tablets. Moreover, since acetaminophen has a peculiar bitter taste, formulation-like devices such as masking for suppressing the bitter taste are also required.
- acetaminophen has a very low drug price (500 mg tablet: 9.80 yen / tablet, 300 mg tablet: 8.50 yen / tablet, 200 mg tablet: 7.60 yen / tablet), and thus the production cost Therefore, the selection of the raw materials and the manufacturing method, the contrivance, etc. are considered as the issues to be studied.
- the price of the additive to be added is often equivalent to several times that of acetaminophen, and reducing or reducing the additive is important for the problem of reducing the production cost.
- the fluidized bed granulation method is the most widely used method for producing pharmaceutical preparations.
- it is necessary to add a relatively large amount of additives to improve fluidity and moldability. It is difficult to reduce the size of the tablet.
- the fluidized bed granulation method is a method in which granules are once prepared by wet granulation, and tableting is performed by adding a lubricant or the like, so that the number of steps is increased and the production cost is also increased.
- the dry direct compression method directly compresses the mixed powder, which reduces the number of steps and leads to a reduction in manufacturing costs, but compared to the dry granulation method and wet granulation method that produce granules. Since the fluidity of the mixed powder is poor, there is a problem in mass variation and compression moldability.
- acetaminophen is a powder with extremely strong secondary cohesion due to intermolecular force (van der Waals force), electrostatic charging, etc., extremely poor fluidity, and complicated particle shape.
- van der Waals force intermolecular force
- electrostatic charging etc.
- extremely poor fluidity and complicated particle shape.
- the dry direct hitting method to formulate fen.
- acetaminophen crystals produced in the crystallization process in API production are difficult to control the hardness and particle size of crystals due to the size of the equipment used and the outside air conditions that change depending on the season.
- the generated crystals need to be pulverized and made uniform.
- acetaminophen of various hardness and particle size is uniformly pulverized with a pin mill or hammer mill
- acetaminophen with a small particle size may be excessively pulverized. Since the surface area is large, the chargeability is enhanced, and the fluidity is further deteriorated, the adhesion to the inner surface of the apparatus is also increased, which is a major factor that the workability is deteriorated.
- the particle shape and particle size distribution also fluctuate, and the secondary agglomeration situation also fluctuates, so the dissolution rate of the final product (tablet) may also fluctuate.
- the present inventors examined the use of the acetaminophen drug substance in order to enable the formulation by the dry direct compression method by improving the fluidity of acetaminophen.
- tablets obtained by compressing the crushed and sized powder by blending the additive with the acetaminophen drug substance, and powders blended with the acetaminophen drug substance with a dispersant or solubilizer We conducted extensive research on premixed drug substances that were crushed and sized.
- acetaminophen is usually acetaminophen which does not undergo a pulverization step described later, in the present invention, “unground” acetaminophen, acetaminophen “unground product” or simply “unground” However, it is not limited to those that have not been subjected to a pulverization step.

- Patent Document 1 is described as a direct compression method, in the examples, as a pretreatment, wet cake-like microcrystalline cellulose and water are mixed, and the solid content is about 15%. After forming a slurry, colloidal silicon dioxide is mixed and spray-dried to form aggregates in which microcrystalline cellulose and silicon dioxide are closely associated with each other, and then acetaminophen and other additives are mixed. And then tableting.
- the production method of Patent Document 1 is a direct hitting method in which the additive is preliminarily liquefied as a pretreatment and is dried for direct hitting with a spray dryer or the like.
- the production method of the present application is the simplest direct compression method that does not require such pretreatment, and mixes and compresses the drug and additive in powder form.
- Patent Document 2 discloses that when a drug and an additive are mixed as a pre-process in the preparation by direct tableting, the drug content in the preparation of a drug having an average particle size of 40 ⁇ m or less is particularly high. A method of mixing a drug and a flow modifier when the content is as low as 20% by weight or less is described.
- Patent Document 3 discloses that a medicinal component-containing surface-modified powder obtained by mixing a medicinal component and a surface-modified base material to improve the surface is excellent in fluidity, and is a tablet produced by dry direct compression.
- the present invention relates to a preparation containing a high content of acetaminophen, particularly a miniaturized tablet (ordinary tablet, slow-release tablet) obtained by a dry direct compression method having excellent dissolution properties, hardness, and drug content uniformity. It is an object of the present invention to provide a method for producing a premixed drug substance consisting of acetaminophen, a dispersing agent, and optionally a solubilizing agent with improved fluidity and increased manufacturability. . In particular, the present invention improves the chargeability and fluidity of acetaminophen, and does not require pretreatment by a wet method. It is an object of the present invention to provide a method for producing a tablet by a dry direct hitting method.
- acetaminophen As a result of intensive research to solve the above problems, the present inventors have used unmilled acetaminophen as a drug substance when formulating acetaminophen. It has been found that the flowability and chargeability of acetaminophen can be improved by blending additives such as dispersants and crushing and sizing without using a large amount of various additives. As a result, it has become possible to formulate acetaminophen by the simplest dry direct hitting method, which has been conventionally difficult to produce acetaminophen formulations.
- a pulverizing and sizing machine is used.
- a pulverizing and sizing machine By selectively pulverizing and sizing crystals and agglomerates with a large particle size and uniformly dispersing and adhering additives such as a dispersant on the surface of acetaminophen particles, It has been found that low flowability is improved, and preparations such as miniaturized tablets and sustained release tablets with excellent dissolution and moldability and bitterness masking can be produced.
- the moldability may be poor and the hardness may be insufficient, but the unmilled acetaminophen and the additive are blended.
- a tablet having excellent hardness can be obtained by adding a small amount of water by spraying or the like and adjusting the water content of the powder before blending the water-soluble additive. .
- a dispersant and, if desired, a solubilizer may be blended into unground acetaminophen, and pulverized and sized using a pulverizing and sizing machine. It has been found that by dispersing and adhering solubilizers, the chargeability and fluidity of acetaminophen are improved, and it can be produced as a premix drug substance with excellent manufacturability.
