Definitions
- the present invention relates to a pH-independent sustained-release preparation that continuously releases a drug from a hide-mouthed gel layer.
- Sustained-release preparations are highly useful preparations that can reduce the number of administrations and maintain drug efficacy by controlling the drug concentration in blood.
- drugs that need to be taken 3 times a day such as ibuprofen (disappearance half-life 2 hours) and phenol-propanolamine (disappearance half-life 4 hours), were changed to twice a day. Is possible.
- the effective concentration of theophylline and the like and the blood concentration of a drug with a narrow range of side effects can be controlled to a predetermined concentration, thereby making it possible to reduce side effects and maintain the efficacy.
- Patent Document 1 discloses a hide-mouthed gel matrix formulation in which a core composed of a drug and a water-soluble polymer substance is coated with the same kind of water-soluble polymer substance.
- Patent Document 2 discloses a compression-molded product of a drug, a hide-mouth gel base, and an enteric coating base.
- the Ido Mouth Gel Base is a water-soluble polymer with the ability to form a hyde mouth gel, such as carboxybule polymer, hydroxyethylenosenorerose, hydroxypropinoremethinoresenorerose, Hydroxypropinoresenorelose, methinoresenorelose, canoleboxoxymethinoresenolose, sodium carboxymethylcellulose, polyethylene oxide, pullulan, sodium alginate and the like are known.
- Patent Document 1 Japanese Patent Laid-Open No. 63-215620
- Patent Document 2 Japanese Patent Laid-Open No. 62-120315
- Patent Document 3 Japanese Patent Laid-Open No. 10-273440
- an object of the present invention is to provide a pH-independent sustained-release preparation of Compound A or a salt thereof.
- a sustained-release matrix preparation containing Compound A or a salt thereof contains a hydrated gel base such as a carboxyvinyl polymer.
- a solubilizing agent for the compound By adding an organic acid such as citrate, tartaric acid, malic acid, fumaric acid, malonic acid, succinic acid or maleic acid as a solubilizing agent for the compound, the pharmaceutical ability of a pharmaceutically active substance containing compound A or a salt thereof elution was found to be able to P H-independent controlled.
- the present invention is based on the above-described novel findings and comprises the following features.
- the viscosity of a 0.2% by weight aqueous solution of carboxybule polymer (20rpm, 25 ° C) is 4000 4.
- organic acid is one or two or more acids selected from the group power of citrate, tartaric acid, malic acid, fumaric acid, malonic acid, succinic acid and maleic acid.
- the sustained-release preparation of the present invention elutes a drug exhibiting pH-dependent solubility without depending on pH.
- the dissolution rate of the drug does not change due to the liquidity of the digestive juice in the digestive tract, and the variation in the blood drug concentration within and between individuals is minimized. can do.
- a Hyde mouth gel matrix layer it is possible to extend the maximum blood concentration time without reducing the absorbability. Has an excellent effect.
- FIG. 1 shows the dissolution test results of the hydrochloride salt of Compound A of Comparative Example 1. ⁇ JP 1st liquid (pHl.
- FIG. 2 shows the dissolution test results of the conventional preparation of Comparative Example 2. ⁇ Japan Pharmacopoeia 1st liquid (pHl. 2); Yokkaichi Pharmacopoeia 2nd liquid (pH6.8) +0. L% Tween 80
- FIG. 3 shows the dissolution test results of the sustained-release preparation of Comparative Example 3 (formulated with kenic acid of Example 1).
- O JP 1st liquid pHl. 2
- Yuriko JP 2nd liquid pH 6.8 +0.
- FIG. 4 shows the dissolution test results of the sustained-release preparation of the present invention described in Example 1. ⁇ Japan Pharmacopoeia 1st liquid (pHl. 2); Hatcho JP 2nd liquid (pH6.8) +0. L% Tween 80
- FIG. 5 shows drug plasma concentrations when the preparation of the present invention of Example 1 or the conventional preparation of Comparative Example 2 is orally administered.

- Figure 1 shows the results of a dissolution test of Compound A hydrochloride alone.
- Compound A hydrochloride showed a large difference in dissolution rate between the first solution of JP disintegration test and the second solution containing 0.1% Tween 80.
- JP disintegration test 2nd liquid +0. L% Tween 80, 6
- the elution rate did not reach 20%, indicating that it is hardly soluble around the intestinal pH. Therefore, the results in Fig. 1 show that the elution of Compound A hydrochloride is greatly influenced by the liquid composition and liquidity of the elution environment.
- test conditions are as follows.
- Test solution Japanese Pharmacy Disintegration Test Method 1st liquid (pHl. 2) 900mL, 2nd liquid 900mL (pH6.8) + 0. l% Tween 80
- Fig. 2 shows the results of the dissolution test of the conventional preparation.
- the conventional preparation a large difference was observed in the dissolution rate between the first solution of JP disintegration test and the second solution containing 0.1% Tween 80. Further, it was confirmed that the initial dissolution was remarkably fast in any of the test solutions. Therefore, the results in Fig. 2 show that the dissolution of the normal preparation is greatly influenced by the liquid composition and liquidity of the dissolution environment, and moreover it is an immediate dissolution type.
- Comparative Example 3 For the purpose of clarifying the role of citrate contained in the present invention, the following formulation was prepared. This formulation corresponds to a formulation not blended with citrate of Example 1.
- the hydrochloride of compound A and crystalline cellulose were mixed and granulated by high-speed stirring granulation. Blow constant temperature drying was performed at 60 ° C. for 16 to 18 hours, and sieving was performed with 30 mesh. The sieved product was further mixed with carboxybule polymer and magnesium stearate, and tableted. The tablet mass was adjusted to 150 mg (equivalent to 6 mg hydrochloride of Compound A). This tablet was subjected to the dissolution test for the hydrochloride salt of Compound A in the same manner as described above, and the results shown in FIG. 3 were obtained.
- the sustained-release preparation (tablet) of the present invention was prepared as follows.
- Canoleboxyvininole polymer 15 Og Crystalline cellulose 113. Og
- the hydrochloride salt of Compound A, crystalline cellulose and citrate were mixed and granulated by high-speed stirring granulation. Blow constant temperature drying was performed at 60 ° C for 16-18 hours, and sieving was performed with 30 mesh. Carboxybule polymer and magnesium stearate were further added to the sieved product, mixed and tableted. The tablet mass was adjusted to 150 mg (equivalent to 6 mg of Compound A hydrochloride). This tablet was subjected to the dissolution test for the hydrochloride of Compound A in the same manner as described above, and the results shown in FIG. 4 were obtained.
- the elution rate of the hydrochloride of Compound A is not different between JP 1st and 2nd liquids, it is not affected by the environmental composition and liquidity of the elution test, and immediate elution is suppressed. This shows that zero-order release has been achieved stably for up to 6 hours.
- the sustained-release preparation of the present invention elutes a drug exhibiting pH-dependent solubility without depending on pH.
- drug elution is less susceptible to elution properties and composition, and when administered orally to a patient, the elution rate of the drug does not change depending on the nature of the digestive fluid in the gastrointestinal tract.
- by forming a Hyde mouth gel matrix layer the maximum blood concentration time can be extended without lowering the absorbability.
