Description of the invention: [Technical field to which the invention pertains] The present invention relates to a fungicide-containing and polymer-coated core microparticle having a high bioavailability, in particular, one which can be compared after oral administration. Good solubility and faster dissolution rate, combined with small volume of fine particles, which allows for a wider range of body absorption, and a higher bioavailability fungicide and polymer for better absorption. Innovative designer of coated core particles. [Prior Art] According to 'Itoconazole or (+)-cis-4-[4-[4-[-4[[2-(2,4~dichlorobenzyl)-2-) , 2, 4-tris(s)-l-ylmethyl)-1,3-dioxalyl-4-yl]methoxy]phenyl]-1-hexahydropyridinyl]phenyl]-2 , 4-dihydro-2-1(1-mercaptopropyl)-3H-1, 2,4-triazol-3-one is a broad spectrum fungicidal compound for oral, parenteral administration And partial use and disclosed in U.S. Patent No. 4,267,179. However, in the use of the above-mentioned U.S. Patent No. 4267179, it is a substance which is insoluble in water, and therefore cannot be effectively absorbed after being taken up; and the orally corrected itotazole is orally administered. The preparation 'is easily affected by the pH value of food and individual gastric acid, resulting in considerable individual differences. Itoconazole is better dissolved under PH2·〇, so it is less soluble in the human body and less effective in use. That is, the development and release of the "Candus with core of fungicide and polymer coating" announced on December 11, 1998 in China, the core of the core coated with fungicide and polymer. The main body of the 1281867 series comprises: a) a center, a circle or a spherical core: b) a coated film comprising a hydrophilic polymer selected from the group consisting of 1,4-methylcellulose, methacrylic _, (d) Cellulose and polyvidone, and a fungicide selected from itaconium naz〇le and saperconazole; C)-selected from polyethylene glycol Coating a polymer layer characterized by the core diameter 600-700 microns (25-30 mesh); Thus, in order to achieve the medication for the human π __ mold, the can having better solubility, absorption efficiency of the promoter body. ,... ▼ a ~ acupoints of the moon muscles of the core of the core coating of the core of the coating" Although it can reach the (four) of the mouth (four) treatment _ money expected effect 'but in its actual implementation but found that due to If the nucleus is too small (such as 30-35 mesh), it will aggregate into a block during the coating process, so that the core diameter can only be set at a minimum of 25, between the meshes, causing its dissolution efficiency after oral administration into the human body. There are restrictions, and it is impossible to achieve a better solubility, no treatment for the age of money. SUMMARY OF THE INVENTION The present invention has a high bioavailability fungicide and polymer coated core microparticles, which are sprayed onto the microparticle core by a special coating layer and a coating layer.

In addition, the particulate matter may further comprise different additives such as thickeners, lubricants, surfactants, preservatives, mismatches and chelating agents, electrolytes and other active ingredients such as fire suppressants, bactericides, disinfectants Or vitamins. The particulates can be conveniently designed into different pharmaceutical dosage forms. Suitable dosage forms comprise an effective particulate fungicide content as described above. Preferably, the microparticles are filled in a hard animal capsule such that, for example, 50 to 100 mg of the active ingredient is obtained per dosage form. For example, an animal capsule having a size of Ν〇·0 is suitable for designing particulate matter from 19 to 25 percent by weight of itotazole or spaconazole, equal to about 100 mg of active ingredient. According to the invention, the microparticles can be conveniently prepared in the following manner by preparing a drug coating solution by dissolving an appropriate amount of a fungicide and a polymer and an acidic substance in a suitable solvent system. = The solvent system consists of a mixture of methylene chloride and an alcohol, which is characterized by the change in ethanol compared to '丨 ethanol: with, for example, methyl ethyl ketone. The topping should contain 5 - methylene chloride as a solvent for the drug. Since the base cellulose is not completely soluble in the methylene chloride, at least, for example, it is necessary to add a person to a relatively low dichloride. A calcined/alcohol from 80/20 [heavy 蜃α Ί/>lcr to β / _ neck buckles 祀 「 "番旦Ί ratio" to 55/45 [heavy ratio], especially about 60/40固体]. Solid content, such as fungicides and high molecular polymers, 1281867 in the drug coating solution ranging from 4 to 7% [by weight], about 6% 隹. 30-50 mesh core drug coating The treatment can be conveniently operated in a rotary spray granulator equipped with a spray rate. The spray rate should be carefully adjusted. If the spray rate is too slow, some of the drug coating solution will be dried and the product will be lost. The spray rate will be too fast. Over-wet and lumpy, the block is the most serious problem, initially using a lower spray rate, and the coating process is carried out until the particle length is longer and then the spray rate is increased. The atomized air pressure also affects the coating process, low atomic air pressure The force leads to the formation of larger particles and the tendency to condense into agglomerates. The high atomic air pressure can be imagined to the danger of the drug solution being dried out. However, this effect is not a question of fins. Therefore, the atomized air pressure is almost They are all set to the maximum value. The volume of fluid air can be controlled by operating the exhaust valve of the instrument, and it is designed in such a way as to get the best particle circulation. If the volume of air is too low, it will cause beads. Insufficient flow; too high air Zhao will block 2% of the particulate matter due to the reverse flow generated by the instrument. In this process, the optimal condition can be opened by opening the exhaust valve to a maximum of + 50% ' The opening is gradually increased to about 60% of the maximum value as the coating process proceeds. The coating process uses an inlet air temperature ranging from 40 ° C to about 50 Å and the rotating disk speed is about 6 Torr, which is well rpm. Operation. The temperature may accelerate the reaction process, but the disadvantage is that the solvent evaporates too much and the coating liquid cannot be evenly distributed on the surface of the particulate matter. The guide 10 1281867 (four) pole coating * forms too many holes, when large When the coated particles are coated, the solubility of the drug may be significantly reduced to no reach, 'obviously, the optimal reaction process temperature will advance and the essence of the core and fungicides will be batched. The volume, solvent and spray rate are related. The parameter setting of the optimum coating result will be == in the following examples. The coating treatment under these conditions found that the non-filament compound was applied to have a money-transfer type. The drug-coated core of the spray granulating bed granulator, the anti-condensation solution can be prepared by dissolving the appropriate antimony-containing anti-coagulation polymer in a suitable solvent system, such as dichloromethane and alcohols. The mixture is preferably ethanol, and the ethanol can be changed with, for example, butyl hydrazine, and the ratio of the chloroformamide/alcohol used is similar to that of the thin coating treatment, so the range can be from about 80 to 20 [weight ratio 〕 to 55/45 [weight ratio], especially 0/40 [heavy weight ratio] 'in the anti-condensation jet solution anti-coagulation polymer content 'range to 4 to m weight ratio], preferably about 6%, this Anti-condensation spray solution is good for stirring in anti-condensation treatment The parameter settings for the last step of the operation must be described in detail in the examples below for the drug application process. A further drying step may be required after application of the anti-condensation polymer layer. After the injection has been completed, the instrument with operating parameters can easily remove excess residual solvent for about 5 to 15 minutes. Both the over-coated and anti-condensation processes are preferably operated under an inert gas such as nitrogen, and the coating device should be placed on the ground, and a suitable solvent recovery system for a sufficient concentration system should be provided for the 1281867 package. The drug-coated and blocked coated microparticles can be filled in a hard gelatin capsule [Νο.0] using a standard automatic glue filler, and an appropriate covering and deionizing device can effectively prevent electrostatic charge generation. The capsule filling speed may affect the weight distribution and needs to be controlled. Good results are obtained when operating the instrument to 75% to 85% of maximum speed and in many cases at full speed. Using the aforementioned processing parameters, a convenient, reproducible production process can be obtained to prepare a coating comprising a 30-50 mesh core, a zero fungicide, a high molecular polymer and a thin seal. A particulate material covering the polymer layer. Pharmacokinetic studies have shown that the particulates are characterized by good solubility and bioavailability. Example: a) Itoconazole coating solution was added to a suitable container by adding dichloromethane [337.5 kg] and ethanol [180 kg], stirring was continued with a stirrer, and poloxamer 407 (22. 5 kg) was added. And citric acid [3kg] disturbed _ solution, then add itoxazole (30kg) and hydroxypropyl methylcellulose [3kg], confirm the dissolution and then add [20·lkg] talcum powder, finally Division 1 OOinesh division network standby. b) Anti-coagulation coating solution Take a suitable container, add dichloromethane [15kg] and ethanol [15kg] with stirring in a stirrer, add [2·lkg] hydroxypropyl methylcellulose and [300g] propylene glycol to dissolve. Then add 12 1281867 [4.5kg] talcum powder, and finally sieve the 100mesh sieve for use. c) Drug-loading engineering A rotary spray granulation device equipped with a rotary disk of diameter lm is used to rotate 30-50 mesh (300-500 micrometers) of sugar core (70·5kg) into a flowing state. In the granular equipment, the inlet air temperature is set to 40°C-50°C, and the inlet air volume is 30-35 cubic meters per minute. The exhaust air volume is 38 cubic meters per minute. The rotary disk speed is 60-80 revolutions per minute. The pressure of 3. 5-4. 5 kg / cm ^ 2 spray volume from 400g per minute slowly increased to 800g per minute, when the drug is completed, dried at 50 ° C -55 ° C dry air for 20 minutes. d) After the outer coating layer is dried, the inlet air temperature is set to 50-55 °C, the inlet air volume and the outlet air volume remain unchanged. The rotating disc speed is 80-90 rpm and the gun pressure is about 4.5 kg/square. The centimeters are sprayed at 600-700g per minute and are continuously operated to completion. e) Final drying stop spray and reduce the rotary disc to 10 revolutions per minute, the inlet air temperature is increased to 55 ° C -60 ° C for 30 minutes, and finally the heating temperature is stopped, about 25 ° when the product is cooled to room temperature C, take the appropriate container to fill the material. f) sieved to the 16mesh sieve on the upper layer of the multi-element screening machine, and the 30mesh sieve on the lower layer is sifted into 16mesh or more [defective], 16-30mesh [good], 30mesh or less (defective), and 13 after sieve 1281867 Contained in a closed container. g) Capsule filling The sieved fine particles are filled in a No. 0 capsule with a fully automatic capsule filling machine, each capsule containing about 520 mg of microparticles, which is equivalent to 100 mg of itoconazole. The isoconazole-containing capsules consisting of the above special formulas have good solubility and greatly improve the bioavailability. 14 1281867 Clinical Trials: 1. The Itocon saliva has a metabolic cycle of 96 hours in the human body, and both the composition of the present invention and the conventional composition contain 100 mg of itaconazole (itraconazole). 2. For 24 healthy volunteers, the oral capsule test was carried out using the composition prepared according to the present invention (Icomein M·) and the commercially available composition (Sp〇ranox), and each of the first, second, and second after oral administration. · 5, 3, 3 · 5, 4, 4 · 5, 5, 6, 8, 1 , 12, 24, 48, 60, 72, 8 stomach 4, 96 hours to draw blood and compare the blood with Iraq The content of toconazole.
