[0018] The method for producing bosutinib tablets of the present invention comprises the following steps: (Step A) Preparing a composition comprising bosutinib, an excipient, and a disintegrant. (Step B) A step of preparing a granulated product by wet granulation of a wet composition prepared by adding a granulation liquid to the composition prepared by Step A. The solvent in the granulation liquid is added in an amount of 30 to 40 parts by mass per 100 parts by mass of the wet composition. (Step C) A step of compressing and molding the granulated product from Step B to prepare pharmaceutical tablets. Optionally, (Step D) the pharmaceutical tablet obtained in Step C is subjected to a coating treatment to prepare a film-coated tablet. Each step will be described below.
[0019] (Step A) is a step of preparing a composition containing the active ingredient bosutinib (hydrate), an excipient, and a disintegrant, in which each component is added in a predetermined amount to prepare a uniform mixture. The mixing may be performed using a stirring granulator, a fluidized bed granulator, a V-type mixer, or the like. Here, a binder, a colorant, a fluidizing agent, a stabilizer, a preservative, or a flavoring agent may be added. The mixing may be performed as long as it is visually confirmed that each component is a uniform mixed composition.
[0020] (Step B) is a step of preparing a granulated product by adding a granulation liquid to the composition of step A to prepare a wet composition, and wet granulating the composition. The granulation liquid may be a solution containing a solubilizer and / or a binder. The granulation liquid may be a volatile solvent, such as water, methanol, ethanol, or acetone. An aqueous solvent containing water is preferred, and the granulation liquid is preferably an aqueous solution containing a binder and / or a solubilizer. In this step, the amount of the solvent in the granulation liquid is 30 parts by mass or more and 40 parts by mass or less relative to 100 parts by mass of the wet composition obtained by adding the granulation liquid to the composition in step A. If the amount of the solvent added in the granulation liquid is less than 30 parts by mass, the active ingredient dissolution of the tablet prepared will be low. On the other hand, if the amount of the solvent added in the granulation liquid is more than 40 parts by mass, granulation with an appropriate particle distribution will not be achieved, and the operability of the subsequent formulation process will be reduced. The amount of the solvent in the granulation liquid is preferably 30 parts by mass or more and 38 parts by mass or less relative to 100 parts by mass of the wet composition.
[0021] The granules are prepared by wet granulation, in which a granulation liquid is added to a mixture of formulation ingredients and mechanical granulation is performed. Granulation causes each ingredient, such as bosutinib, excipients, binders, and disintegrants, to adhere to each other, producing granules with a certain particle size distribution. Examples of the granulation procedure include rolling granulation, fluidized bed granulation, stirring granulation, extrusion granulation, etc. In the present invention, the stirring granulation method is preferred. After the wet granulation operation, the prepared granules are dried. Drying is performed at 40 to 80°C, and the drying is terminated when the mass loss of the granules is 1 to 10%. The mass loss of the granules is preferably 1 to 4%. The drying operation can be performed using a permeation dryer, a fluidized bed dryer, or the like.
[0022] After the granulation operation, it is preferable to carry out a sieving operation to adjust the particle size of the obtained granulated product. The sieving operation is preferably a method of passing through a screen. In the present invention, it is preferable to carry out sieving by passing through a 1 to 5 mm screen. The granules used in the present invention preferably have a 30 mesh sieve passing rate of 25% or less and a 200 mesh sieve passing rate of 20% or less, and more preferably have a 30 mesh sieve passing rate of 20% or less and a 200 mesh sieve passing rate of 15% or less.
[0023] (Step C) is a step of compressing and molding the granulated product from step B to prepare a pharmaceutical tablet. It is preferable to add a lubricant to the granulated product as a post-added component. Also, an excipient or a disintegrant may be added as a post-added component. Alternatively, any component such as a colorant, a flow agent, a stabilizer, a preservative, or a flavoring agent may be added. The granulated product, the lubricant, and any post-added components are mixed, and the mixture is molded into a tablet shape by tableting or the like to prepare a pharmaceutical tablet.
[0024] (Step D) is a step of preparing a film-coated tablet by applying a coating treatment to the pharmaceutical tablet obtained by step C. The film-coated tablet can be prepared by dissolving or suspending a coating agent and an optional plasticizer, light-shielding agent, colorant, etc. in an aqueous solvent to prepare an aqueous solution of the coating agent, attaching it to the tablet surface by spraying, etc., and drying the tablet surface by blowing hot air to remove the solvent. The solvent may be removed under reduced pressure to volatilize the aqueous solvent and dry the tablet. The aqueous solvent is a solvent containing water, and may be water alone or a mixed solvent of water and a water-miscible organic solvent. Examples of the water-miscible organic solvent include ethanol and acetone.
[0025] The present invention is a method for producing a pharmaceutical tablet that ensures proper dissolution of bosutinib. After oral ingestion, bosutinib is a drug in which the active ingredient is dissolved and absorbed, and a predetermined amount is delivered to the diseased site to exert its medicinal effect. In a dissolution test using a pH 5.0 solution, bosutinib desirably has a dissolution rate of 55 to 85% in 15 minutes, and more preferably a dissolution rate of 65 to 75%. The bosutinib tablet produced by the production method of the present invention exhibits proper dissolution, and can be a pharmaceutical preparation that ensures the desired medicinal effect.

[0032] [Test Example 1] Dissolution test at pH 5.0, paddle method, 50 rpm The dissolution rates of the tablets of Examples 1 to 3 and Comparative Examples 1 and 2, and a commercially available bosutinib tablet (Bosulif (registered trademark) tablet 100 mg) as a control formulation were evaluated by the Japanese Pharmacopoeia Dissolution Test Method 2 (paddle method) using a McIlvaine buffer solution of pH 5.0. The test method used a dissolution tester (NTR-6600A, Toyama Sangyo Co., Ltd.) and an ultraviolet-visible spectrophotometer (UV-1900, Shimadzu Corporation, measurement wavelength 267 nm) to evaluate the dissolution rate at 15 minutes with a test liquid volume of 900 mL, a test liquid temperature of 37±0.5°C, and a paddle rotation speed of 50 rpm. The results are shown in Table 1.
[0033] TIFF2025075898000001.tif15151
[0034] From the results of Test Example 1, the dissolution rates in 15 minutes were 65-75% in Examples 1 to 3, which were equivalent to the performance of existing bosutinib tablets. In contrast, the tablets in Comparative Examples 1 and 2 had physical properties that did not achieve the appropriate dissolution property of bosutinib.
