Definitions
- the present invention relates to a pretreatment method such as a tableting step or a granulating step in the production of a pharmaceutical preparation using a drug substance having irregular powder physical properties (particle diameter, particle shape, density, etc.).
- a dry direct compression method of tableting a mixture of an active substance and an excipient without preparing granules dry direct compression method
- dry granulation method dry roller compactor method, roll granulator method
- wet granulation method wet granulation method
- the drug substance and the excipient powder are continuously supplied quantitatively into the manufacturing process, and the mixing, binder addition, granulation, drying, sizing, and tableting are performed in the same continuous production system.
- Continuous granulation systems capable of producing solid pharmaceutical preparations of high quality have been developed. For example, an additive is blended with the drug substance and supplied to a continuous granulation system via a quantitative feeder, and then a binder solution is added.
- a process analysis system PAT system
- a method is recommended that facilitates scale-up of granulated products of the same quality by monitoring and controlling the situation.
- the powder physical properties (particle size, shape, particle density, etc.) of the drug substance particles to be processed fluctuate depending on the season (summer and winter) and lots even among the same drug manufacturers, as well as between different drug substance manufacturers. It is well known. Then, if the powder physical properties of the drug substance particles fluctuate, the product quality in the post-process fluctuates, and it becomes difficult to manufacture a product having the same quality. However, a pretreatment method such as homogenization of drug substance particles for eliminating variation caused by seasonal variation or the like has not been known.
- the particle size of drug substances and additives before about 1970 was relatively large, and there were many drug substances with high solubility and irregular particle sizes, and there was no problem in solubility and dissolution rate. Furthermore, the air conditioning equipment in the working environment of pharmaceutical manufacturing at that time was undeveloped and the humidity was high (probable), so there was almost no adverse effect such as secondary aggregation of the drug substance and additives, and the force acting on those particles was gravity. (Mass) was dominant. On the other hand, recent drug substances have become hardly soluble, and drug substance manufacturers have used pin mills, hammer mills, jet mills, etc. to finely convert drug substances to improve solubility etc. In many cases, the drug substance is supplied (commercially available) with pulverized and irregular powder properties.
- the drug substance As the drug substance is finely pulverized, electrostatic charging, intermolecular force (Van der Waals force), surface energy, and the like act strongly. In addition, even when a drug substance with extremely high solubility is formulated with an insoluble additive, the drug substance with high solubility selectively binds to the binder mist by spray addition of a binder solution. There is a case where the particles are aggregated to form a gel (pulverized powder) on the surface and dissolution is delayed. In particular, a drug substance having a low content and a unique color tone may cause a problem in uniformity such as color spots and spots when formulated.
- Powder physical properties (particle size distribution, particle shape / density, etc.) in drug substance synthesis also differ depending on the installation environment of facilities at each drug substance maker. It is well known that the same equipment of the same manufacturer is affected by seasonal fluctuations (temperature and humidity in summer and winter) and the environment in which the equipment is installed. For example, plants for the synthesis and crystallization processes of drug substances have been installed. In many cases, the environment is not an environment where air conditioning is complete and temperature control is carefully performed, as in the manufacturing process of pharmaceuticals, but an environment close to outdoors. In particular, the temperature control in the cooling step at the end of the synthesis of the drug substance is almost complete, and there are still few cases of production in an environment with complete air conditioning equipment.
- the cooling rate in the cooling process varies greatly depending on the size of the equipment and the environment of the equipment.
- the powder properties particle size, particle size distribution, particle shape, particle density, chargeability, intermolecular force
- Etc. are inevitable to fluctuate.
- the synthesized drug substance contains large-sized crystals generated in the crystallization step in the manufacturing process, lumps due to secondary aggregation, etc., and contains many large particles of 500 ⁇ m or more.
- the particle size is not uniform.
- drug substance manufacturers supply the drug substance by pulverizing it using a jet mill, pin mill, hammer mill or the like (commercially available).
- Pharmaceutical (pharmaceutical) manufacturers that produce fine granules, granules, capsules, tablets, and the like are suffering because of easy aggregation.
- the obtained fine granules, granules, capsules can be obtained.
- the physical properties (particle size, shape, density, etc.) of the preparations and tablets fluctuate, and it has been difficult to produce a final product having the same quality at all times.
- Drug substance fine particles having a particle size of 50 to 60 ⁇ m or less have extremely strong electrostatic charge and exist as secondary aggregated particles.
- Large and irregular particles having a particle size of 500 ⁇ m or more look like single particles, but are actually particles in which needle-like crystals, flake-like crystals, and the like are accumulated and stacked (Photo 1 (FIG. 1) and Photo 1). 2 (see FIG. 2: enlarged photograph in the center of photograph 1). If these are pulverized with a strong impact force, they become fine particles having a size of 50 to 60 ⁇ m or less, so that secondary aggregated particles are generated.
- ibuprofen has a melting point of 74 ° C. to 77 ° C.
- a strong impact force such as a pin mill or a hammer mill
- it is stuck to the pulverizing pin or the inner wall due to heat generation.
- continuous operation becomes difficult.
- acetaminophen drug substance is supplied (commercially available) with particles pulverized by a strong impact force such as a pin mill or a hammer mill, so that there are many secondary aggregated particles and many needle-like particles. As a result, the liquidity is reduced.
- the present invention provides a pretreatment method for preparing a drug substance having powder properties, particularly, irregular particle sizes.
- the pretreatment method according to the present invention (hereinafter, sometimes referred to as “the pretreatment method”) is required to have better fluidity and homogeneity of powder than those obtained by other production methods.
- a pretreatment method such as a tableting step or a granulation step in the production of pharmaceutical preparations, which can be a powder having high applicability to a dry direct compression method or a production method using a continuous granulation system. Make it an issue.
- this pretreatment method is a sizing method, it is not always performed before the tableting step or the granulating step.
- APIs with high pharmacological activity, poor solubility and high cohesiveness are finely pulverized using a jet mill, pin mill, hammer mill or the like to improve the solubility.
- fine particles having a particle size of 50 to 60 ⁇ m or less may be excessively pulverized when pulverized by a pin mill, a hammer mill, or the like.
- electrostatic charging, intermolecular force (Van der Waals force), surface energy, and the like is strong. Acts and secondary aggregates to form a drug substance with extremely poor fluidity.
- the secondary agglomerated drug substance particles and the like tend to be non-uniformly dispersed in the binder solution, as a result, the secondary agglomerated partly reduces the elution rate and small lumps are present. In some cases, it became a granulated material, and the uniformity of the content became somewhat difficult. Further, the pulverization step may cause a decrease in yield and an increase in cost due to adhesion to the wall surface of the apparatus. In addition, there is a problem that some drugs become unstable due to mechanically strong force such as pulverization or pressure, impact, heat generation and the like during compression molding and tableting.
- the present inventors have improved the fluidity of the drug, and by controlling the particle size by the action of selectively crushing only large particles without overcrushing, the solubility and homogeneity are improved, and the productivity is improved. It has been studied as an object of the present invention to provide a pretreatment method in the production of a pharmaceutical preparation for enhancing the pharmaceutical preparation.
- the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, when formulating a drug, powder physical properties (particle size, shape, particle density, etc.) are not only between different drug substance manufacturers, Even for the same drug substance manufacturer, if the drug substance fluctuates depending on the season (summer and winter) or lots, additives such as dispersants are blended, and the mixture is crushed and sized once or multiple times. It has been found that it is important to disperse and adhere an additive such as a dispersant on the surface of the drug particles, and to obtain a powder having a specific particle size distribution.
- An additive such as a dispersant added to the drug substance only needs to be able to improve fluidity and suppress secondary aggregation, and it is not always necessary to form a continuous layer.
- a dispersing agent is added to a drug substance containing 1% by weight or more of particles of 500 ⁇ m or more and 10% by weight or more of particles of 60 ⁇ m or less based on 100% by weight of the drug substance.

- the mixture is crushed and sized to disperse and adhere an additive containing at least a dispersant to the surface of the drug substance particles.
- a powder containing 50% by volume or less of particles of 200 ⁇ m or more and 70% by volume or less of particles of 50 ⁇ m or less was prepared.
- fluidity, solubility, and homogeneity are improved without using a large amount of various additives, and the fluctuation range of powder physical properties (particle size, particle size distribution, particle shape, density, etc.) is improved.
- the dispersant and, if desired, the solubilizing agent and the other additives are blended with the drug substance, using a crushing and sizing machine, crystals or aggregates having a large particle size of the drug substance are used.
- the lumps are selectively crushed and sized, and the dispersant and other additives are dispersed and adhered to the surface of the drug substance particles, thereby improving the cohesion and low fluidity of the drug, improving dissolution and moldability. It has been found that preparations such as miniaturized tablets and sustained-release tablets that are excellent in taste and bitterness masking can be produced.
- Pulverization, crushing, sizing, and dispersion are described as follows.
- 1) Pulverization is a unit operation to apply a strong impact to large particles using a hammer mill, pin mill, jet mill, or the like to adjust the particles to a small size.
- Sizing / dispersion is a process in which the drug substance particles, in which aggregated particles and crystals (needle, columnar, flake, etc.) are accumulated and laminated, are slightly disintegrated to disintegrate, disperse, and regulate the size. It is a unit operation that is partially overlapped with the operation similar to the pulverization and is easily confused, but is clearly divided in the field of powder engineering.
- the present invention relates to, for example, the following (1) to (13), but is not limited thereto.

Since the scale-up is easy and the manufacturing process can be simplified, the production cost can be reduced. Further, according to the pretreatment method, it is not necessary to use a large amount of various kinds of additives in order to improve fluidity and solubility, so that it is possible to produce a tablet that is smaller than before. it can.
- the powder prepared by this pretreatment method even in the case of a drug substance where tableting failure is likely to occur due to direct contact with the metal surface of a die or punch of a tableting machine, the surface of the drug substance particles has a dispersing agent. Since it is coated with additive particles such as an insoluble additive, a surfactant (solubiliser), and a water-soluble polymer, it also has a secondary effect such as reduction in occurrence of tableting trouble. Furthermore, when the powder prepared by this pretreatment method is subjected to a dry direct compression method, the water content is adjusted to a value suitable for tableting (the total amount of the powder is 100% by weight, depending on the physical properties and the mixing ratio of the drug substance and the additives). On the other hand, by adding approximately 0.5 to 3.0% by weight of water), secondary aggregation can be reduced and high tablet hardness can be ensured.
