Definitions
- the present invention relates to an aqueous suspension for producing a sucrose polysulfate aluminum (sucralfate) preparation and a method for producing the same.
- Sucralfate is a drug substance used as a therapeutic agent for gastritis, stomach and duodenal ulcer.
- the present invention has an effect of adsorbing and inactivating hepsin secreted in the stomach, thereby improving tissue repair ability and promoting a biological defense effect leading to healing of ulcer and inflammation.
- Sucralfate is precipitated by reacting sucrose polysulfate with alminium chloride as described in JP-B-44-11673 and JP-B-44-16037.
- the wet powder was dispersed and then dried by heating (spray drying), and the obtained dried product was used as a bulk material.
- the reason for this is that the use of a dried product is advantageous in the case of producing a solid preparation.
- Sucralfate is insoluble in water, and its particles are, as far as possible when applied to a living body, as much as possible when considering its ability to adsorb to tannin. It is important to reduce the size and increase the surface area.
- the conventional aqueous sclarfate suspension was prepared by mechanically pulverizing a dry powder obtained by heating and drying a wet powder of sclarulfate, pulverizing the dried powder into water again, and mixing.
- the production method comprising the steps of drying, pulverizing, and suspending the wet powder in water is inferior in operability and costly.
- the fineness of the dried powder by pulverization has a large variation in particle size.
- the finely powdered skull sulfate is easily dissipated at the time of encapsulation and opening in containers, and during the operation of drug product manufacturing. It has drawbacks such as the possibility of contamination, and was not an industrially superior production method.
- sucralf-wet wet powder was separated by centrifugation, and then dried.Therefore, it was difficult to employ an industrial continuous integrated production method. It was difficult to improve the efficiency of production.
- the sulphur plate of the present invention can be prepared, for example, by the method described in JP-B-44-1673 and JP-B-44-16037, namely, by adding aluminum ion (aluminum ion) to the salt of sucrose polysulfate. (Aluminum hydrochloride, aluminum polychloride, etc.).
- the obtained sucralfate is washed with water, suspended in water or an aqueous medium, and subjected to a pulverizing step. At this time, the amount of water or the aqueous medium is appropriately added or removed so that a desired concentration of a skullfate suspension stock solution can be set after pulverization. On the other hand, after the washing operation, Then, a crushing process can be performed after separating the wet powder of scleral unit by centrifugation or the like, resuspending it in water or an aqueous medium. The amount of water or aqueous medium used is added so as to obtain the desired concentration of the sucralfate suspension stock solution.
- the aqueous suspension stock solution for producing sucralfate preparations is a skullafuratu solution obtained by reacting aluminum sucrose polysulfate sodium salt with aluminum ion. Then, the wet powder is washed with water, and the separated wet powder is pulverized without drying. Since unreacted raw materials and the like remain in the aluminum chloride reaction solution at the time of the production of skeletal powder, and a large amount of chlorine ions produced as a result of the reaction are contained, they are removed. Therefore, it is necessary to perform a washing operation.
- the reaction liquid is removed by repeated operations of standing sedimentation, supernatant exchange, stirring, and standing sedimentation, and further centrifuged to obtain a sucralfuit wet powder. After dispersing in a medium, it is pulverized to obtain an aqueous suspension of sclaral foot.
- the centrifugal separation operation is omitted, and the skull flakes dispersed in water are directly crushed.
- the purpose of the present invention is to obtain a desired aqueous suspension of sclaral stump.
- a highly basic aluminum chloride raw material for example, a highly basic aluminum chloride
- the centrifugal separation operation can be omitted, so that the suspension stock solution production process is simplified and suitable for mass production. Not only can it reduce the amount of waste generated by the sucralfate manufacturing process.
- a desired concentration can be set depending on the amount of water or an aqueous medium present at the time of pulverization.
- the concentration of sucralfate is 1 to
- the average particle diameter of the fine particles is preferably set to 50 Af or less.
- sucralfate concentration of this average particle size is set to 1.1 to: 1.5 g /, it is difficult to separate into two layers, an aqueous layer and a slurry layer. Thus, a stable suspension can be obtained.
- the pulverizer used for pulverizing sucralfate there is no particular limitation on the pulverizer used for pulverizing sucralfate as long as it can obtain a particle size of 50 A or less.
- the time required for atomization depends on the capacity of the model used, but it takes 3 to 30 minutes at room temperature or under water cooling (10 to 25 ° C), preferably 5 to 20 minutes. It is preferable to repeat the refining operation until the desired particle size is obtained.
- suitable preservatives for suppressing the growth of microorganisms such as molds, for example, benzoic acid, p-oxybenzoic esters, and chlorobutanol are added to water.
- a preservative can be transported to the drug product manufacturing site or stored in a container as a stock solution for a long period of time without deteriorating the inherent properties of sucralfate. Can be saved. Instead of or together with the addition of the preservative, it is added to the sucralf suspension. An operation of heat sterilization may be added.
- a sterilization operation after preparing the stock solution, for a long period of storage, or before transferring to a preparation site, for example, at 95 to 100 for about 10 to 30 minutes.
- the aqueous suspension of sucralfate obtained according to the present invention may be used as it is or diluted depending on its concentration, for production of a suspension of sucralfate and for production of aqueous softeners and cataplasms. It can be used as a stock solution.

- sucrose sodium sulfate sodium salt 10 g was dissolved in 100 kg of water, and a solution of 6 g of aluminum dihydroxycyclolide in water was added to the solution under stirring. When gradually added, a white precipitate gradually precipitated. Next, 1N caustic soda was added to adjust the pH to 4.5 to 5.0, the mixture was stirred at room temperature for about 30 minutes, and the white precipitate was collected by filtration. This was washed several times with water to remove unreacted sucrose polysulfate, and 17.2 g of a wet powder was obtained. The aluminum content was 14.2% and the sulfur content was 8.61%.
- the mixture was wet-pulverized for 10 minutes using a tabletop colloid mill (manufactured by Nippon Seiki Seisaku-sho) to obtain an aqueous suspension of sucralfate (ULW-M) 40ffl £.
- the concentration of the stock solution was 1.2 gZfflg for sucralfate.
- a laser diffraction type particle size distribution analyzer manufactured by Nikkiso Co., Ltd.
- an unmilled aqueous suspension (ULW) was prepared by simply stirring the same raw materials as in this example without performing wet milling.
- Table 2 shows the particle size distribution measurement results
- Table 3 shows the sedimentation rate over time.
- sucralfate preparations After adding 797 g of water to 383 g of the sucralfate wet powder and dispersing it, wet milling with a tabletop colloid mill (Milmix: manufactured by Nippon Seiki Seisakusho) to obtain an aqueous suspension stock solution for the manufacture of sucralfate preparations. About 1 liter was obtained. Samples were taken at 5 minute intervals after pulverization, and the average particle size, the cumulative 50% particle size, and the proportion of particles smaller than the particle size were examined using a laser diffraction type particle size distribution analyzer (manufactured by Nikkiso). Table 6 shows the results.
- Example 7 Aqueous suspension of sucralfate dried powder obtained in Reference Example 2 (conventional product, hereinafter ULD-M) and aqueous suspension of sucralfate wet powder obtained in Example 6 (The present invention product, hereinafter ULW-M) was examined for sedimentation.
- the slurries of the two suspensions had similar densities of approximately 1.2 g / ⁇ , suggesting that there is a critical slurry concentration at which the aqueous layer does not separate.
- the critical slurry concentration depends on the particle size of the sclart, and it can be said that the water layer does not separate even at a low concentration as the particle size decreases. From the results in Table 7, it was obtained by the present invention. If the aqueous suspension is set to a particle size of 50 Af or less and the sucralflate concentration is set to 1.2 gZ or more, it is difficult to separate into two layers, an aqueous layer and a slurry layer. It can produce a uniform suspension of natural sucralfate.
- UJDW-M is slightly more stable to heptasulfate during the drying process of sucralfate wet powder, so IJLW-M is more stable.
- the suspension obtained by the present invention was changed to a viscous substance (a quasi-state) with a smaller amount of hydrochloric acid than the conventional ULDM.
- the mixture was incubated at 37 ° C. for 30 minutes, and immediately after the reaction was completed, immediately adjusted to 200 ffl £ with CLB, and filtered to obtain a sample solution.
- the BSA standard solution was diluted to 0.1, 0.2, 0.4, 0.6, 0.8, and 1.0 mg / ffig to prepare a standard solution.
- the standard solution and the sample solution 0.1 ⁇ were collected, and the protein assay reagent 5 was added.
- the absorbance at a wavelength of 595 nm is measured, and the amount of unreacted BSA in the sample is determined from the calibration curve of the standard solution.
- the horizontal axis indicates the weight ratio of sucrose octa sulfate (SOS) to BSA, and the vertical axis indicates the specific adsorbed protein amount.
- SOS sucrose octa sulfate
- the mixture was centrifuged (3000 rpm, 5 minutes), and the supernatant was recovered.
- Rats were fed 48 hours after eating, the laparotomy was performed under ether anesthesia, the pylorus was ligated, and a sucralfunit suspension preparation was orally administered at a dose of 1 Zk.Water was removed for 18 hours during the ligation procedure. Rats were sacrificed and stomachs were removed to evaluate their anti-ulcer effect. The evaluation was performed with a score of 0-5 according to the method of Adami et al. (Ethanol acute gastric mucosal lesion model)
- the rats were fasted for 24 hours before the administration of sucralfate, and were orally administered at a dose of l Zkg to a rat that had been deprived of water for 18 hours.
- the evaluation was expressed as the sum of the major axis of the gastric mucosa damaged area.
- Test Example £ Characteristics of formulated sample
- plUt4.91 specific gravity was 1.16, showed a viscosity of 291.7 cps, and showed good dispersibility and tackiness.
- sucralfate aqueous suspension preparation pH: 4.21, specific gravity 1.06, viscosity 53.4 cps. Good dispersibility.
- the aqueous suspension of the scaffold obtained directly from the wet powder according to the present invention showed comparable values in both physical properties and pharmacological activity as compared with those from the conventional dry powder. Therefore, it is possible to obtain an aqueous suspension of sucralfate which is equivalent in both physical properties and pharmacological activity while solving the problems of the conventional production method. That is, according to the present invention, a stock solution can be obtained in a short process and at low cost without using a process of poor operability such as heat drying and pulverized water suspension in the production process. Furthermore, in the case of wet powder, there is no fine powder generated by the grinding of dry powder, and there is no contamination of the manufacturing environment (such as health aspects of the manufacturer). It is easy to make continuous and is an industrially superior production method. Also, there is no dissipation of the fine powder during transportation or use, and the accompanying environmental pollution due to the formulation process can be suppressed.
