Abstract

PROBLEM TO BE SOLVED: To provide a tablet that is excellent in acetaminophen bitterness-masking effect while taking as well as high elution property of the drug in the stomach, and to provide a method of producing the tablet containing acetaminophen for suppressing preparation free from sticking onto its machine when tableting.SOLUTION: The tablet contains: (A) coated particles containing acetaminophen; and (B) granulated particles having particle size of 150 to 600 μm containing sugar alcohol and starch.

Description

  The present invention relates to a tablet containing acetaminophen.

  Acetaminophen is an excellent drug as an antipyretic analgesic, but has a bitter taste and needs to be masked in order to improve the dosage. As a masking method for unpleasant taste, a method of adding a sweetener or a corrigent, a matrix method of dispersing a drug in a carrier by spray-drying a liquid in which a gastric or water-insoluble polymer is suspended or dissolved, A coating method in which a nucleus containing a drug is coated with a film containing a gastric polymer or a water-insoluble polymer is mainly known.

  However, even if the coated particles are coated (masked) with acetaminophen, if they are tableted to prepare a tablet, the coating film may be destroyed and bitterness may be felt when taken, achieving the desired masking effect. The result will be poorly taken. In particular, orally disintegrating tablets and chewable tablets disintegrate in the oral cavity after ingestion, and thus can be taken without water, but the above bitter taste is very easily felt. In view of the above, there has been a demand for a tablet that can suppress the bitter taste of acetaminophen during taking even if the tablet is prepared by tableting.

Hereinafter, the present invention will be described in detail.
The tablet of the present invention comprises (A) acetaminophen-containing coated particles and (B) granulated particles having a particle diameter of 150 to 600 μm containing sugar alcohol and starch.

(A) Acetaminophen-containing coated particles (A) The acetaminophen-containing coated particles are not particularly problematic as long as they are coated with acetaminophen, but are preferably coated with a water-insoluble coating agent. Note that “water-insoluble” indicates that the amount dissolved in 10,000 mL of water is 1 g or less than 1 mL. The coating agent that forms the coating film contains a water-insoluble coating component, and can further contain a plasticizer and an antacid.

  The average particle diameter of the acetaminophen particles serving as the nucleus is preferably in the range of 50 to 600 μm, and more preferably in the range of 100 to 400 μm. If the average particle size is less than 50 μm, the particles are fine, so that the aggregation of particles easily occurs, and the granulation tends to proceed, the coating becomes non-uniform, and the bitterness masking property may be inferior, whereas if it exceeds 600 μm Although there is no problem with the bitterness masking property, there is a possibility that the roughness becomes strong and the dosing property is deteriorated.

  In the present invention, the average particle size means a sieve of 1000 μm, 850 μm, 500 μm, 355 μm, 250 μm, 150 μm, 75 μm, 45 μm, 20 μm with an inner diameter of 75 mm and a sample amount of 10 g. The particle diameter is 50% of the cumulative mass when the test is performed based on the second method and measured. For those having an average particle diameter of 100 μm or less by the above measurement method, the average particle diameter of 50% of the cumulative mass when measured using a laser-type scattering diffraction particle size distribution analyzer (manufactured by BECKMAN COULTER) The particle size was taken.

  Examples of water-insoluble coating components include ethyl cellulose, aminoalkyl methacrylate copolymer E, aminoalkyl methacrylate copolymer RS, carboxymethyl ethyl cellulose, carboxyvinyl polymer, cellulose acetate phthalate, shellac, purified shellac, methacrylic acid copolymer LD, methacrylic acid copolymer L, Listed products such as methacrylic acid copolymer S, Japanese pharmacopoeia such as acrylate / methyl methacrylate copolymer emulsion, Japanese pharmacopoeia, food additives and the like can be used. These can be used individually by 1 type or in combination of 2 or more types. Of these, ethyl cellulose is preferred from the viewpoint of usability and odor. The amount of the water-insoluble coating component is not particularly limited, but is preferably in the range of 30 to 60% by mass in the coating agent.

  The plasticizer is presumed to have a function of imparting appropriate spreadability to the solution containing the coating agent and facilitating film formation. Examples of the plasticizer include those described in official documents such as standards for pharmaceutical additives such as triacetin and triethyl citrate (Pharmaceutical Daily Inc.). These can be used individually by 1 type or in combination of 2 or more types. Among these, triacetin and triethyl citrate are preferable in view of film formability, and triacetin is more preferable in terms of taste. Although the quantity of a plasticizer is not specifically limited, The range of 5-15 mass% in a coating agent is preferable.

  It is preferable to add an antacid to the coating film from the viewpoint of controlling solubility. As antacids, synthetic hydrotalcite, magnesium hydroxide, dry aluminum hydroxide gel, aluminum hydroxide gel, magnesium alumina hydroxide, aluminum hydroxide / sodium bicarbonate coprecipitation product, aluminum hydroxide / magnesium carbonate mixed Examples thereof include dry gels, aluminum hydroxide / magnesium carbonate / calcium carbonate coprecipitation products, and the like. These can be used individually by 1 type or in combination of 2 or more types. Of these, synthetic hydrotalcite and magnesium hydroxide are preferable, and synthetic hydrotalcite is more preferable. Although the quantity of an antacid is not specifically limited, 10-80 mass% is preferable in a coating agent, More preferably, it is 30-60 mass%. If the amount of the antacid in the coating agent is too small, the dissolution property in the stomach and the rapid release property may be lowered, and if it is too much, the film forming property may be lowered.

  The amount of the coating agent is not particularly limited, but the mass ratio of coating agent / acetaminophen is preferably in the range of 0.05 to 0.35, and more preferably in the range of 0.15 to 0.25. When the above value is too small, the coating film becomes thin, and when it is too large, the coating film becomes thick. However, when the value is within the above range, a balance between the bitter taste masking effect and the securing of immediate release can be achieved.

  (A) The average particle diameter of the acetaminophen-containing coated particles is preferably 50 to 600 μm, and more preferably 100 to 400 μm.

  (A) Although the compounding quantity of particle | grains is not specifically limited, 20-70 mass% in a tablet is preferable. The amount of acetaminophen is preferably 100 to 300 mg / tablet.

  (A) Although the manufacturing method of particle | grains is not specifically limited, The core acetaminophen particle | grain can be obtained by coating with the coating component containing a coating component and the plasticizer and an antacid agent as needed. The coating with the coating agent is generally wet coating, but is not limited thereto. In the case of wet coating, for example, a dispersion liquid in which a coating agent is dispersed in an arbitrary dispersion medium (hereinafter, also referred to as a coating agent dispersion liquid) is sprayed on acetaminophen particles serving as a nucleus. Preferred examples of the dispersion medium for the coating film composition include hydrophilic solvents such as water and ethanol.

  The method for spraying the coating agent dispersion is not particularly limited, but it is preferable to use a coating apparatus having a fluidized bed because the coating agent can be uniformly attached to the surface of the core acetaminophen particles. Thereby, it is possible to perform an excellent coating that is uniform and has less unevenness in elution. Moreover, the strength of the coating film to be formed is high, and the possibility of breaking by tableting or chewing is reduced.

  An apparatus as shown below can be used for coating fine particles. There are multiplex capable of stirring rolling fluidized bed coating, CF granulator capable of centrifugal rolling bed coating, flow coater capable of fluidized bed coating, GPCG, and Spirer flow. In particular, in an apparatus capable of the Wurster method (for example, a GPCG Wurster specification machine), efficient fine particle coating is possible. The Wurster method is a system in which a spray liquid is sprayed onto the core particle powder from the bottom of the fluidized bed toward the top.

(B) Granulated particles having a particle diameter of 150 to 600 μm containing sugar alcohol and starch (B) By blending the particles, (A) destruction of the acetaminophen-containing coated particles during tableting can be suppressed. In the case of sugar alcohol alone, disintegration in the mouth decreases, and in the case of starch alone, a high tableting pressure is required to maintain hardness, and (A) the acetaminophen-containing coated particles are easily destroyed, resulting in a bitter taste masking effect. Is inferior.

  Examples of the sugar alcohol include mannitol, erythritol, xylitol, and the like, which can be used alone or in combination of two or more. Of these, mannitol is preferred.

  The blending mass ratio of the sugar alcohol: starch in the component (B) is preferably 98: 2 to 50:50, more preferably 96: 4 to 75:25, from the balance of bitterness masking effect, disintegration in the mouth, and ingestion. 95: 5 to 85:15 are more preferable. When the ratio of starch is high, the bitterness masking effect may be insufficient.

  (B) Although the compounding quantity of particle | grains is not specifically limited, 30-80 mass% in a tablet is preferable, 40-75 mass% is more preferable, 50-70 mass% is further more preferable. (B) When the compounding quantity of particle | grains is less than 30 mass%, cushioning property is insufficient and sufficient bitterness masking property may not be obtained. Moreover, from the point of sufficient masking effect, 50 mg or more is preferable with respect to 100 mg of acetaminophen, and 200 mg or more is more preferable. Although an upper limit is not specifically limited, It is 600 mg or less.

  (B) The particle size of the particles is 150 to 600 μm, preferably 150 to 425 μm, more preferably 150 to 355 μm, and still more preferably 150 to 250 μm. The thing of the particle size of this range can be obtained by sieving. (B) If the particle size is less than 150 μm, adhesion to the equipment occurs during tableting, while if it exceeds 600 μm, the bitterness masking effect becomes insufficient.

  (B) Although the manufacturing method of particle | grains is not specifically limited, For example, the wet granulation method etc. can be selected. Specifically, after mixing sugar alcohol, starch, and optional components as required, an aqueous solution containing a binder such as polyvinyl alcohol, hydroxypropylcellulose, hydroxypropylmethylcellulose, etc. is sprayed in a fluidized bed granulator. However, it can be obtained by wet granulation. Examples of the fluidized bed granulator include a GPCG series, WSG / WST / WH series from POWREC Co., Ltd., a flow coater, a spiral flow, etc. from Freund Sangyo Co., Ltd. Although it does not specifically limit as a drying method after granulation, For example, in the case of a fluidized granulation method, it can dry, blowing 40-100 degreeC warm air in a fluidized tank. The obtained granulated particles are appropriately sieved to obtain a desired particle size.

  In addition, as for content of the sugar alcohol and starch in (B) particle | grains, 90-98 mass% is preferable in (B) particle | grains. Moreover, 0.01-10 mass% is preferable for content of the binder in the said aqueous solution.

  The tablet of the present invention may further contain (C) a fragrance and / or a sweetener. By blending the component (C), the masking effect is improved. The component (C) can be blended in the particles (A) and (B), but is preferably blended separately from the particles (A) and (B).

  Although it does not specifically limit as a fragrance | flavor, Peach, grapefruit, apple, etc. are mentioned, It can use individually by 1 type or in combination of 2 or more types. Of these, peach is preferred. 0.5-2 mg is preferable with respect to 100 mg of acetaminophen, and 1.0-1.2 mg is more preferable.

  Examples of the sweetener include aspartame, sucralose, acesulfame potassium, saccharin, saccharin sodium, trehalose, thaumatin and the like, and these can be used alone or in combination of two or more. Of these, sucralose is preferable. The sweetener is preferably 1.0 to 5.0 mg and more preferably 2.0 to 3.0 mg with respect to 100 mg of acetaminophen.

  In the tablet of the present invention, in addition to the above components, other tablet components such as an excipient, a disintegrant imparting disintegration, and a lubricant may be used singly or in combination, as long as the effects of the present invention are not impaired. An appropriate amount can be blended by appropriately combining species or more.

  As the excipient, a commonly used excipient can be used. For example, crystalline cellulose, ethyl cellulose, cellulose such as low-substituted hydroxypropyl cellulose and derivatives thereof, starch and derivatives thereof such as corn starch, potato starch, hydroxypropyl starch, sugars such as lactose and mannitol, sugar alcohols, and the like. The content of the excipient may be in the range of 0 to 20% by mass, preferably 0 to 10% by mass with respect to the tablet. Regarding the excipient content, too much cellulose and its derivatives will lead to a decrease in disintegration in the mouth, too much starch and its derivatives will lead to a reduction in bitterness, and too much sugar and sugar alcohol will cause disintegration in the mouth. This leads to a decrease in property and adhesion.

  Although a disintegrating agent does not need to be contained in a tablet, disintegrating from the inside of a tablet can be obtained by mix | blending a disintegrating agent, and the disintegrating property of the whole tablet can be improved. Examples of the disintegrant include crospovidone (polyvinylpyrrolidone), carmellose calcium, croscarmellose sodium, low-substituted hydroxypropyl cellulose, carboxymethyl cellulose, carboxymethyl starch sodium, croscarmellose sodium, hydroxypropyl starch, and the like. . Of these, crospovidone is preferred. However, in the present invention, when the disintegrating agent is used to improve the disintegration property in the mouth, if the blending amount is increased, there is a possibility that a decrease in hardness or deterioration of appearance may occur due to storage. In addition, since disintegration is obtained by the present invention, the content of the disintegrant is preferably 5% by mass or less, more preferably 3% by mass or less, more preferably 3% by mass or less in the tablet in order to prevent a decrease in hardness and appearance deterioration due to the above storage. It is also possible to have a composition that does not contain an agent.

  As the lubricant, a commonly used lubricant can be used. For example, magnesium stearate, sucrose fatty acid ester, sodium stearyl fumarate, polyethylene glycol, talc, stearic acid and the like can be mentioned. The content of the lubricant is preferably 0.1 to 1% by mass relative to the tablet.

  In addition, the orally disintegrating tablet of the present invention includes stabilizers such as sodium edetate and benzoic acid, pigments such as titanium oxide, iron sesquioxide, and food yellow No. 5, malic acid, tartaric acid, citric acid, succinic acid, An acidulant such as fumaric acid can also be blended.

  The tablet of the present invention is prepared by, for example, mixing (A) acetaminophen-containing coated particles and (B) granulated particles having a particle diameter of 150 to 600 μm containing sugar alcohol and starch, and tableting the mixture. Can be obtained at The molding pressure (tablet pressure) at the time of tableting is appropriately selected so as to achieve the target tablet hardness, preferably 0.1 to 1.2 t, and more preferably 0.1 to 1.0 t. The tablet hardness varies depending on the tablet size, but is preferably about 3 kgf (tablet hardness measuring instrument (manufactured by Yamato Scientific Co., Ltd.)) or more. According to the present invention, a good masking effect can be obtained by using granulated particles having a specific particle diameter containing sugar alcohol and starch. Furthermore, by adjusting the ratio of starch, the tableting pressure required to obtain a suitable hardness can be kept low (1.0 t or less), and as a result, a better masking effect can be obtained.

  The mass of the tablet is preferably 20 to 2000 mg / tablet although it depends on the diameter and shape of the tablet. Among these, in the case of a tablet having a diameter of 11.0 mm, 200 to 700 mg / tablet is preferable from the viewpoint of disintegration and tablet moldability. The shape of the tablet is not particularly limited, but may be a round shape, a caplet shape, a donut shape, an oblong shape or the like, a laminated tablet, a dry-coated tablet, etc. A secant line may be attached. In addition, the packaging of the orally disintegrating tablet is not particularly limited, but PTP (Press Through Package) may be packaged to prevent moisture.

  The tablet of the present invention is preferably an orally disintegrating tablet because it is excellent in masking effect and also excellent in disintegration. An orally disintegrating tablet refers to a tablet that is composed only of saliva in the oral cavity, disintegrates the tablet in the oral cavity by shearing or chewing with the tongue and upper jaw, and swallows the saliva dispersion of disintegrated particles.
