Drug preparations

TECHNICAL FIELD

[0001] The present invention relates to a drug preparation, more particularly, to a drug preparation that has antitussive and expectorant effects and can be advantageously used as an antitussive expectorant or the like.

BACKGROUND ART

[0002] Conventionally, an antitussive component and expectorant component are added to many drug preparations for colds, since diseases such as the common cold cause coughs and sputum. Many antitussive expectorants that mainly aim to suppress coughs and remove sputum are also commercially available.

[0003] However, the commercially available drug preparations for colds are not sufficiently effective in suppressing coughs and removing sputum, since the amount of the antitussive and expectorant components is limited. Neither are the commercially available antitussive expectorants sufficiently effective, particularly in the antitussive effect.

[0004] Therefore, development of drug preparations having an improved antitussive effect has been desired.

DISCLOSURE OF THE INVENTION

[0005] In order to obtain drug preparations having improved antitussive and expectorant effects, the present inventors have studied the efficacy of various antitussives and their combinations with other medicinal components and have found that if fudosteine, which is useful as an expectorant but does not exhibit an antitussive effect by itself, is combined with an antitussive, the antitussive can exhibit a markedly enhanced antitussive effect. This finding has led to the completion of the present invention.

[0006] Specifically, the present invention provides drug preparations containing fudosteine and an antitussive.

[0034] The drug preparation of the present invention is prepared by appropriately combining the above-described components with a pharmaceutically acceptable additive into a solid, semisolid, or liquid preparation to be orally administered such as a tablet preparation, granule preparation, fine granule preparation, powder preparation, hard capsule preparation, soft capsule preparation, pellet preparation, troche preparation, drop preparation, suspension preparation, emulsion preparation, liquid preparation for internal use, syrup preparation, dry syrup preparation, inhalant preparation, or oral mucoadhesive preparation, according to a conventional method. The medicinal components may be made into microparticles such as microcapsules, nanocapsules, microspheres, or nanospheres prior to preparing the above-mentioned preparation.

[0035] There are no specific limitations to the method for preparing the drug preparation of the present invention. Various methods can be employed. For example, when it is necessary to prepare a granulated powder for preparing a tablet preparation, granule preparation, fine granule preparation, powder preparation, capsule preparation, pellet preparation, dry syrup preparation, or the like, conventional granulation is employed. Examples of the granulation include wet granulation using a solution or dispersion liquid containing water or an organic solvent such as spray granulation, agitating granulation, fluidized bed granulation, rolling granulation, or rolling fluidized bed granulation and dry granulation using a powdery binder such as compression granulation.

[0036] A powder or granulated powder containing the medicinal components can be mixed and packed into a plurality of packages to prepare a granule preparation, fine granule preparation, or powder preparation. A powder preparation, granulated powder, small tablet preparation, or the like is capsuled using a capsuling machine to prepare a capsule preparation. A powder of the medicinal components, powder preparation, fine granule preparation, granule preparation, or pellet preparation is mixed with an additive and the mixture is compression molded to prepare a tablet preparation.

[0037] A tablet preparation, granule preparation, or the like is coated with a coating agent using pan coating, fluidized bed coating, roll coating, or a combination of these, to prepare a coated preparation such as sugar-coated tablets, film-coated tablets, or coated granules. The coating agent may be applied by spray coating wherein the agent is dissolved and/or dispersed in water or an organic solvent or dry coating wherein the agent is directly sprayed and heat, pressure, or the like is applied. The amount of the coating agent can be appropriately selected according to the dosage form or the like. The amount is usually about 0.1-100 weight % for a tablet preparation, about 0.1-200 weight % for a pellet or granule preparation, or about 0.1-300 weight % for a fine granule preparation.

[0038] Usually, a liquid preparation for internal use such as a syrup preparation, elixir preparation, limonade preparation, extract preparation, or drink preparation, as well as a hard capsule preparation, soft capsule preparation, or the like in which a liquid or semisolid substance is capsuled, can be produced by a method wherein the medicinal components are mixed with, dissolved in, or dispersed in a part of a solvent such as purified water, followed by adjusting the liquid amount by adding the remaining part of the solvent to the mixture. The pH may be appropriately adjusted using an acid or alkali. The preparation containing a fat-soluble component may be solubilized, emulsified, or suspended using an additive such as a surfactant, solubilizer, emulsifier, or suspending agent. As required, the mixture may be heated, cooled, replaced with nitrogen, filtered, or sterilized during the adjustment.

[0039] The drug preparation of the present invention may be appropriately provided with properties such as stability, sustained releasability, durability, or capability of rapid disintegration or rapid dissolution of the medicinal components, improved solubility, taste masking properties, and capability of imparting improved feeling during the dosing, using an additive or the like. A conventional method can be used for providing these properties. Examples of the method include various methods such as a method of adding the medicinal components to separate granules, a method of preparing multilayer granules from the components, a method of preparing multilayer tablets or core tablets from the components, a method of preparing separate granules from the components and tableting them, a method of preparing microcapsules from the components, a method of preparing a coated preparation such as sugar-coated tablets, film-coated tablets, or coated granules from the components, a method of preparing an effervescent preparation from the components, a method of preparing a chewable preparation from the components, a method of preparing an orally disintegrating preparation from the components, a method of preparing a matrix preparation from the components, a method of pulverizing the components all together, a method of preparing a solid solution from the components, a method of adding a sweetener or cooling agent to the components, a method of adding an antioxidant or stabilizer to the components, and a method of adjusting the composition to have a specific pH, viscosity, osmotic pressure, or salt concentration. These methods may be used in combination.

[0055] In the drug preparation of the present invention obtained as above, fudosteine acts on an antitussive to enhance that effect. Therefore, the preparation is markedly useful as a drug preparation with an excellent antitussive effect, particularly as a drug preparation for colds or an antitussive expectorant.

EXAMPLES

[0056] The present invention will be described in more detail with reference to Examples and Test Examples which should not be construed as limiting the present invention.

Test Example 1

[0057] Antitussive Effect Test:

[0058] The synergetic effect of using fudosteine and an antitussive compound in combination was examined according to the following method. The results are shown in Table 1.

[0059] (Method)

[0060] Five male Hartley guinea pigs for one group, each having a weight of 300-400 g, were used as test animals. According to the method of Miyata et al. (Arch. Int. Pharmacodyn. Ther., vol. 304, p. 277, 1990), the guinea pigs were exposed to SO2 gas using an exposure apparatus for two hours a day in eight consecutive days to cause respiratory tract inflammation. The samples of which the components and dose are shown in Table 1 were orally administered before exposure to SO2 gas once a day in eight consecutive days since the start date of exposure. The guinea pigs were confined in a chamber without being anesthetized. On the date following the last SO2 exposure date, capsaicin (10−6 mol/l) was sprayed over the chamber for two minutes using a ultrasonic nebulizer (TUR-3200, Nihon Kohden Corporation) to cause cough in the guinea pigs. The reaction was observed for two minutes during spraying and 13 minutes following the spraying (15 minutes in total). The frequency of cough during this period was counted.

[0062] These results show that fudosteine did not exhibit an antitussive effect when administered alone. In contrast, dextromethorphan exhibited an antitussive effect when administered alone. Its antitussive effect was enhanced by administration in combination with fudosteine. The dose response was also observed. The synergetic effect on the antitussive effects of using the two medicinal components in combination was exhibited. As is clear from these results, the antitussive effect of the antitussive was enhanced by using fudosteine in combination.

Example 1

[0063] Tablet Preparation:

[0064] Fudosteine (1,200 g), dextromethorphan hydrobromide (60 g), corn starch (38 g), talc (1 g), and magnesium stearate (1 g) were made into a powder for tableting by a conventional method. The powder was tableted using a rotary tableting machine to prepare a tablet preparation in which each tablet had a diameter of 8.5 mm and a weight of 250 mg.

Example 2

[0065] Liquid Preparation:

[0066] Fudosteine (8 g), dextromethorphan hydrobromide (400 mg), erythritol (20 g), caramel (100 mg), sodium benzoate (70 mg), and flavor (100 mg) were dissolved in purified water. An appropriate amount of phosphoric acid was added to the mixture to adjust the pH, followed by adding purified water to the mixture to make the total amount 100 ml, to prepare a liquid preparation.

Example 3

[0067] Tablet Preparation:

[0068] Fudosteine (120 g), dihydrocodeine phosphate (3 g), dl-methylephedrine hydrochloride (5 g), chlorpheniramine maleate (0.8 g), anhydrous caffeine (9 g), potato starch (159.8 g), talc (1.2 g), and magnesium stearate (1.2 g) were made into a powder for tableting by a conventional method. The powder was tableted using a rotary tableting machine to prepare a tablet preparation in which each tablet had a diameter of 8.5 mm and a weight of 250 mg.

Example 4

[0069] Granule Preparation:

[0070] Fudosteine (120 g), dihydrocodeine phosphate (3 g), lyzozyme hydrochloride (3.3 g), chlorpheniramine maleate (7.5 g), corn starch (89.7 g), and trehalose (83.25 g) were made into a granule preparation by a conventional method.

Example 5

[0071] Liquid Preparation:

[0072] Fudosteine (12.8 g), codein phosphate (0.2 g), dl-methylephedrine hydrochloride (0.3 g), lyzozyme hydrochloride (0.24 g, titer), chlorpheniramine maleate (48 mg), anhydrous caffeine (0.24 g), senega powder extract (60 g), erythritol (60 g), and flavor (0.4 g) were dissolved in purified water. An appropriate amount of phosphoric acid was added to the mixture to adjust the pH, followed by adding purified water to the mixture to make the total amount 240 ml, to prepare a liquid preparation.
