Description

The present invention relates to a pharmaceutical composition containing ibuprofen.

Ibuprofen is a type of nonsteroidal anti-inflammatory drug (NSAID) classified as a propionic acid derivative, which inhibits cyclooxygenase (COX) to suppress the production of prostaglandins and exerts an antipyretic and analgesic effect. Ibuprofen is widely distributed not only as an ethical drug, but also as an active ingredient in general medicines such as cold remedies.

In addition to ibuprofen, other drugs known to be used as active ingredients in general cold medicines include the cough suppressant dextromethorphan and the expectorant guaifenesin.
Patent Document 1 discloses a water-suspendable pharmaceutical composition containing a granular composition useful as a pharmaceutical carrier that can be used to prepare a pharmaceutical composition having the ability to be rapidly suspended in an aqueous medium, and lists ibuprofen, dextromethorphan, guaifenesin, etc. as examples of the pharmaceutical active substances contained therein.

Patent Document 2 discloses a method for producing a microemulsion concentrate for oral administration of poorly soluble cold medicines, and lists ibuprofen, dextromethorphan, guaifenesin, etc. as examples of poorly soluble cold medicines.

Patent Document 3 discloses a combination preparation containing a first comprehensive cold medicine containing an antihistamine and a second comprehensive cold medicine containing another antihistamine with a different rate of hypnotic effect, as a preparation aimed at improving the usefulness of a comprehensive cold medicine from the viewpoint of QOL by effectively utilizing the hypnotic effect of an antihistamine such as diphenhydramine and highlighting the effect of caffeine. Patent Document 4 discloses a combination preparation containing a first comprehensive cold medicine containing an antihistamine in a first dose and a second comprehensive cold medicine containing the antihistamine in a second dose different from the first dose, as a preparation aimed at the same purpose. These documents disclose that the preparation may further contain ibuprofen, dextromethorphan, guaifenesin, etc.

All of the above documents indicate that multiple active ingredients may be blended in a pharmaceutical product such as a general cold remedy, but there is no mention or suggestion whatsoever about the problem that the simultaneous blending of (a) ibuprofen, (b) dextromethorphan or a salt thereof, and (c) guaifenesin may cause wetting and/or dissolution due to an interaction between these drugs, resulting in a loss of appearance quality.
An object of the present invention is to provide a pharmaceutical composition which inhibits wetting and/or dissolution due to interactions when the above three components (a) to (c) are simultaneously blended, thereby inhibiting deterioration of appearance quality.

As a result of intensive research, the present inventors have found that the above problems can be solved by adding tranexamic acid or a salt thereof in addition to the above three components (a) to (c), and have thus completed the present invention.
That is, the present invention includes the following aspects.
[1] A pharmaceutical composition comprising ibuprofen, dextromethorphan or a salt thereof, guaifenesin, and tranexamic acid or a salt thereof.
[2] The pharmaceutical composition according to [1], wherein the dextromethorphan or a salt thereof is dextromethorphan hydrobromide hydrate.
[3] The pharmaceutical composition according to [1] or [2], wherein the tranexamic acid or a salt thereof is tranexamic acid.
[4] The pharmaceutical composition according to any one of [1] to [3], which is used for treating colds.
[5] The pharmaceutical composition according to any one of [1] to [4], wherein the pharmaceutical composition is in the form of a tablet, a capsule, a granule, a powder or a pill.

The present invention also provides a method for suppressing deterioration of the appearance of a pharmaceutical composition containing (a) ibuprofen, (b) dextromethorphan or a salt thereof, and (c) guaifenesin, characterized in that the method comprises blending tranexamic acid or a salt thereof. Each requirement in this method (each component, its amount used, its proportion used, etc.) is as described for the pharmaceutical composition of the present invention.

The present invention will be described in more detail below with reference to examples, but the present invention is not limited to these.

(Examples 1-2 and Comparative Examples 1-2)
The main ingredients shown in Table 1 were weighed out in predetermined amounts, granulated in a mortar using a small amount of purified water, and then dried to obtain granules.

(Test Example)
The granules obtained above (Examples 1 and 2 and Comparative Examples 1 and 2) were placed in a glass bottle, sealed, and stored for one week at 60° C. The properties of the granules after storage were compared with those immediately after the start of storage and evaluated.

As shown in Table 2, it was confirmed that the granulated state was maintained in the tranexamic acid-containing group even after storage at 60° C. for 1 week (Examples 1 and 2). On the other hand, in the tranexamic acid-free group, wetting and melting of the granulated state were observed, making it difficult to maintain the granulated state (Comparative Examples 1 and 2).
From the above, it was revealed that tranexamic acid or a salt thereof has the effect of suppressing the interaction between ibuprofen, dextromethorphan or a salt thereof, and guaifenesin.

(Production Examples 1 to 5)
The components were mixed according to the recipe and compounding ratio shown in Section A of Table 3 below, and compressed to obtain plain tablets. The obtained plain tablets were coated according to the recipe shown in Section B to obtain a coating agent.

According to the present invention, it is possible to provide a pharmaceutical composition in which the wetting and/or dissolution caused by the interaction between (a) ibuprofen, (b) dextromethorphan or a salt thereof, and (c) guaifenesin is suppressed by tranexamic acid or a salt thereof, thereby suppressing deterioration of the appearance quality.
