Definitions
- the present invention relates to a solid preparation containing a poorly water-soluble drug, and more particularly to a solid preparation containing pisacodyl.
- Pisacodyl acts directly on the large intestinal mucosa, promotes intestinal peristalsis and promotes defecation, and is mainly used in oral administration. It is known that its properties are extremely insoluble in water.
- pisacodyl has a problem in that the action of pisacodyl is repeated by enterohepatic circulation when absorbed at a site up to the upper part of the small intestine. Therefore, it is preferable that pisacodyl also exerts a small intestinal force on the large intestine.
- Dioctylsodium sulfosuccinate is known as a laxative. Its effect is to act directly on hard stools in the intestine to allow water to penetrate and to soften and swell the stool, thereby facilitating excretion.
- Patent Document 1 a technique for improving the stability of a preparation in which pisacodyl and dioctylsodium sulfosuccinate are simultaneously blended has been reported.
- Patent Document 1 JP-A-57-99521
- Patent Document 2 JP-A-10-203983
- Patent Literature 3 Tokiohei 11—506432
- Patent Document 4 Japanese Translation of International Patent Application No. 11-506433
- pisacodyl and dioctylsodium sulfosuccinate are simultaneously formulated, and an enteric coating agent that releases nuclei containing them from the lower small intestine through the large intestine.
- an enteric coating agent that releases nuclei containing them from the lower small intestine through the large intestine.
- the core is an object to which an enteric coating is to be applied, and in addition to granules and plain tablets obtained by granulating powder containing dioctylsodium sulfosuccinate and pisacodyl, powders, gels, etc. Also contained.
- the enteric coating agent includes capsules that dissolve in the intestine, in addition to granules, films for uncoated tablets and the like. When capsules are used, core granules are packed into enteric capsules to make capsules.
- an enteric coating agent that releases a drug to the lower intestine and lower intestine of the large intestine is defined as the first solution in the Japanese Pharmacopoeia disintegration test method insoluble for 2 hours and the second solution in the second solution.
- the disintegration time exceeds 60 minutes.
- the enteric coating used in the present invention has a lower small intestinal force and a drug in the large intestine. Any release agent can be used, and the object of the present invention can be achieved by applying a multilayer coating containing an enteric polymer such as cellulose acetate phthalate as described in Patent Documents 2 to 4, for example. .
- the amount of pisacodyl is preferably 0.75 to 45 mg, more preferably 5 to 15 mg per dose, from the viewpoint of the purging effect.
- the dosage form is a tablet, 0.75 to 15 mg per tablet is preferred, and 3 to 8 mg is more preferred.
- the compounding amount of dioctylsodium sulfosuccinate has a synergistic effect with pisacodyl, and the point strength of the preparation containing pisacodyl is preferably 3 to 360 mg per dose, and 8 to 30 mg is preferable. More preferred.
- the dosage form is a tablet, 3 to 120 mg per tablet is preferred, and 5 to 30 mg is more preferred.
- the coating amount when the enteric coating agent is directly coated on the core is preferably 110 to 30% by mass based on the mass of the core.
- the core used in the present invention is produced as follows.
- Dioctylsodium sulfosuccinate is dissolved in a solvent such as water or ethanol to form a solution.
- the solution is sprayed or added all at once, and a powder obtained by mixing an excipient, such as light caustic anhydride, is granulated to obtain a powder.
- the solid preparation of the present invention can be obtained by coating the obtained nucleus from the lower small intestine to the large intestine by a known method with an enteric coating agent that releases a drug.
- water-soluble polymer examples include hydroxypropylcellulose, polybutylpyrrolidone, and hydroxypropylmethylcellulose.
- the blending amount of the water-soluble polymer is preferably about 10% by mass of the whole core particles.
- the light acid anhydride is 0 parts per part by weight of dioctylsodium sulfosuccinate. 5-1. Mixing of 5 parts by mass is preferred Mixing of 0.6-1.3 parts by mass is more preferred.
- the lower part of the small intestine which is the drug release site of the present preparation, is a part corresponding to the entrance to the large intestine, and the amount of digestive juice in the digestive tract is small.
- the fluid volume in the human digestive tract generally decreases as the gastrointestinal tract moves from the small intestine to the large intestine. Therefore, when releasing a drug from the lower intestine to the large intestine, the solubility of the drug itself often affects the efficacy.
- Dioctylsodium sulfosuccinate to be incorporated in this preparation is also a surfactant, and its solubility can be improved by blending with a drug. In particular, it is very effective for dissolving poorly soluble drugs such as pisacodyl in a site with a small amount of gastrointestinal fluid.
- pisacodyl and dioctylsodium sulfosuccinate exhibit a synergistic effect by simultaneously releasing a drug from the lower small intestine to the large intestinal site.
- concentration of each component at the target site can be reduced by coating with a general coating, which is a coating that releases the drug in the lower intestine and large intestine even if the two components are orally administered simultaneously.
- the synergistic effect cannot be expected because it is sufficient.
- the solid preparation of the present invention was excellent in solubility at the site of action of pisacodyl, and synergistically improved the purging effect.
- FIG. 1 is a view showing the results of a flow-through cell elution test of DSS and pisacodyl.
- FIG. 2 is a view showing the results of a flow-through cell elution test of pisacodyl.
- FIG. 3 is a graph showing the cathartic effect of simultaneous administration of DSS and pisacodyl, with the vertical axis representing the cathartic expression rate and the horizontal axis representing the sample.
- This formulation was produced according to the formulation shown in Table 1.
- the production method was such that lactose, hydroxypropylcellulose, low-substituted hydroxypropylcellulose, and light silica anhydride were mixed with active ingredient pisacodyl to give a mixture.
- the active ingredient dioctylsodium sulfosuccinate in ethanol The mixture was dissolved in a mixed solution of water and purified water, and this was sprayed into the mixture as a granulation solution to granulate.
- a methacrylic acid copolymer (a mixture of S and L), magnesium stearate, and castor oil are dispersed and dissolved in ethanol and acetone to prepare a coating solution, and the coating solution is added to the core particles in an amount of 8 mg per tablet.
- the coating was applied to obtain a solid preparation of the present invention.
- a core particle produced in the same manner as in Example 1 was not subjected to a coating, and Comparative Example 1 was used.
- Example 1 The dissolution test of the preparations shown in Example 1 and Comparative Example 1 was performed.
- the eluting dioctylsodium sulfosuccinate was quantified by HPLC according to the dissolution test method 3 (flow-through cell method) of the Japanese Pharmacopoeia.
- This test reproduces the behavior of the drug product in the human gastrointestinal tract by changing the liquid properties of the test solution supplied into the cell over time, and is suitable for evaluating the dissolution of the site-directed drug product. ing.
- Test liquid properties Table 2 shows the elution time.
- FIG. 1 shows an elution curve of dioctylsodium sulfosuccinate.
- Example 1 started drug release in a high pH region assuming the lower small intestine, whereas the preparation containing only core particles shown in Comparative Example 1 In this case, it can be seen that the drug release was started at pH 1.2 assuming the stomach.
- This product differs from general enteric products in that drug release is initiated in the lower part of the gastrointestinal tract, which enhances its effect as a laxative. To demonstrate this, the disintegration and dissolution properties of this formulation and a general enteric formulation (commercially available) containing pisacodyl were compared.
- the disintegration time of the preparation of Example 1 was adjusted by the disintegration test method and the shaking method of the Japanese Pharmacopoeia.
- the shaking method is as follows: Place approximately 10 mL of the test solution and one tablet in a 50 mL volumetric flask, shake with a shaker for approximately 100 strokes Z for 3 cm in amplitude, and the time when the tablet disintegrates was recorded.
- the disintegration time was tested using test solution of JP 1 solution (pH 1.2), JP 2 solution (pH 6.8), and pH 8.3.
- a commercially available product was used and evaluated by a shaking method.
- Table 3 shows the disintegration time of each test solution.
- Example 1 The drug release characteristics of Example 1 and a commercially available product were examined using pisacodyl as an index by the flow-through cell method. The results are shown in FIG.
- pisacodil did not dissolve in the pH range corresponding to the upper part of the stomach and the small intestine, and dissolution started in the high pH range corresponding to the lower part of the small intestine. Puru.
- the preparation of the present invention disintegrates in a region having a higher pH, that is, in the lower small intestine, and releases the drug, as compared with a normal enteric preparation. That helped.
- Pisacodyl was dispersed in purified water, and the solution shaken under constant conditions for 5 hours was centrifuged at 3000 min-5 min. Thereafter, the supernatant was collected and the amount of pisacodyl dissolved was quantified by HPLC.
- pisacodyl was dispersed in a solution obtained by adding dioctylsodium sulfosuccinate to a concentration of 0.07%, 0.14%, and 0.35%, and the solution obtained by shaking for 5 hours was added. Centrifugation was performed at 3000 mm for 1 and 5 min. Then, the supernatant was collected and the pisacodyl solution was analyzed by HPLC. The amount of solution was quantified. Table 4 shows the results.
- the rat was laparotomized under ether anesthesia, and the test substance was injected into the ileum 20 cm from the ileocecal portion using a syringe at a rate of 1 mL per 1 kg of body weight of the rat. After laparotomy, he recovered from anesthesia and observed the expression of phlegm until 24 hours later.
- test substance was orally administered to rats at a rate of 5 mL / kg of body weight, and the expression of phlegm was observed until 24 hours later.
- FIG. 3 shows the results.
- no cathartic effect was observed with DSS alone (3.2 mg / kg) in any of the administration routes.
- DSS 3.2 mg / kg
- FIG. 3 shows the results.
- no cathartic effect was observed with DSS alone (3.2 mg / kg) in any of the administration routes.
- synergistic enhancement of the cathartic effect was observed by using pisacodyl in combination with DSS.
- the combination effect of DSS did not show any enhancement effect on the cathartic effect of pisacodyl.
- the formulation of the present invention releases pisacodyl and DSS at high concentrations in the lower intestine and also in the large intestine, and therefore has a synergistic purgative effect as compared to the effects of the drugs alone. It was suggested to improve.
- a sparingly soluble drug such as pisacodyl can be effectively reached at a site where a drug effect is exhibited at a high concentration, and the effect can be synergistically enhanced.
