Abstract

PURPOSE:To obtain a tablet having excellent disintegration property and solubility and high absorbabliy through digestive tracts, by directly compression molding powder containing fureloxasin and a proper additive. CONSTITUTION:The objective tablet can be produced by the direct compression molding of powder containing (A) 60wt.% of fureloxasin [6,8-difluoro-1-(2- fluoroethyl)-1,4-dihydro-7-(4-methyl-1-p-iperazinyl)-4-oxo-3-quinoline carboxylic acid], (B) 10-40wt.% of lactose or crystalline cellulose (excipient), (C) 0.2-15wt.% of hydroxypropyl cellulose having low substitution degree, starch or partially gelatinized starch (disintegrant), (D) 0.2-5wt.% of magnesium stearate or hydrated silicic acid (lubricant) and, as necessary, (E) 0-4wt.% of a binder (e.g. hydroxypropyl cellulose) using a conventional tablet machine. In the case of applying a film coating to the tablet, 3-10wt.% of hydroxypropyl methylcellulose or 0.1-0.5wt.% of titanium oxide is used as the coating material.

[Prior Art and its Problems] When manufacturing tablets of pharmaceutical preparations, a wet granulation method has been used for a long time. This wet granulation method involves a complex process of mixing, hydration, kneading, granulation, drying, sizing, and tableting. However, during this process, unstable pharmaceutical ingredients must be exposed to harsh conditions such as wetting with water and other solvents and drying of solvents by heating, which can lead to changes in quality such as discoloration and decomposition during the tabletting process. There is a problem that is difficult to avoid.

Instead of this wet granulation method, there is a method that does not require heating, kneading, or drying, and involves directly compressing pharmaceutical powder to obtain tablets, which is called the direct compression method. The direct compression method has the advantage of being easy to manufacture because the pharmaceutical powder can be directly molded into tablets, but the applicability of this method largely depends on the compression moldability of the main pharmaceutical ingredient. It is not something that can be enacted by law. For example, the powder of fleroxacin, which is the object of the present invention, cannot be molded as it is by applying molding pressure.

[Means and effects for solving the problem] In order to solve the above-mentioned problem, the present inventor has intensively researched various additives for direct injection to be added to fleroxacin. As a result, we found a powder composition for fleroxacin that was easy to apply directly,
This made it possible to manufacture fleroxacin tablets based on this powder.

For example, lactose is used as an excipient, but it is difficult to obtain tablets with good moldability using ordinary excipients. For this reason, lactose for direct injection with good fluidity (for example, trade name: Tabletose, manufactured by Taiyo Kagaku Sangyo Co., Ltd.) is used. As another excipient, crystalline cellulose (for example, trade name: Avicel, manufactured by Asahi Kasei Industries, Ltd.) is used. The amount added is 5 to 40 of the tablet weight.
% by weight. If the amount added is less than 5%, tablets with good moldability cannot be obtained, and if it is more than 40%, moldability is improved, but the tablets have the disadvantage of becoming larger.

%ol, manufactured by Asahi Kasei Industries, Ltd.), but these disintegrants accelerate the decomposition of fleroxacin and cannot be used in the present invention. Therefore, in the present invention, as disintegrants, for example, low-substituted hydroxypropyl cellulose (for example, trade name, L-NPC1 manufactured by Shin-Etsu Chemical Co., Ltd.), corn starch, potato starch, partially pregelatinized starch (for example, trade name, pcs) are used.
(manufactured by Asahi Kasei Kogyo Co., Ltd.) has the drawback of not only reducing the moldability but also increasing the size of the tablet.

As a binder, hydroxypropyl cellulose (for example, HPC-L, manufactured by Nippon Soda Co., Ltd.) or the like can be mixed as necessary, for example, in an amount of 0 to 4% by weight of the tablet weight.

It is preferable to express it in weight%. If it is less than 0.2%, no lubricating effect will be exhibited, and if it is more than 5%, the binding properties of the tablet will decrease, resulting in the disadvantage that tablets with good moldability cannot be obtained.
