The GB 2 1 5382 1 patent discloses ondansetron, its salts and solvates. Among them, the preparation of basic ondansetron is detailed in several examples. For example, Example 4 illustrates that the preparation of basic ondansetron is methylation with dimethylformamide in dimethylformamide; the product is obtained which is decomposed at 223 ° C-2 24t. In Example 7, the basic ondansetron is 3-[(dimethylamine) methyl] -1,2,3,9-tetrahydro-9-methyl-4H-carbazole-4 in water. -Ketone hydrochloride is obtained by treatment with 2.methylimidazole. The melting point of the ondansetron is 221 ° C -22 1.5 ° C, and then recrystallization in methanol to obtain the melting point 23 PC -232 t Tannone. Example 8 illustrates that the preparation of basic ondansetron is 200528100 1 2 3 9 -tetrachloro-9-methyl-3-methylene--yesterday '卩 坐 -4- 顾 [以 2- Methyl yung mouth sits in a litre and recrystallizes in 1 methanol. The resulting ondanazepam has a melting point that decomposes at 2 3 2 ° C-2 3 4 ° C. Example 1 8 'illustrates that the preparation of the ondansetine was performed in DMF (dimethylformamide) with 3- (chloromethyl) -1,2,3,9-tetrahydro-9-methyl The reaction of -4H-Misoza-4-one with 2-methylimidazozone was followed by purification by column chromatography to obtain ondansetron with a melting point of 228 ° C -229 ° C. Example 19 illustrates that the preparation of basic ondansetron is based on the preparation of 2,3,4,9-tetrahydro-9-methyl- 3-[(2-methyl-1H-imidamine- 1-yl) φmethyl] -1H-carbazole maleate is oxidized with 2,3-dichloro-5,6-dicyano-1,4-benzene-quinone, and then through the column Purification by chromatography gave ondansetron with a melting point of 2 7 ° C-2 2 8.5 ° C. Example 20 illustrates that the preparation of basic ondansetron is based on 2,3,4,9 · tetrahydro-9-methyl · 3-[(2-methyl-1H-imidazol-1-yl) in THF. Methyl] -1Η-yttriol-4 · ol and 2,3 -a ^ chloro-5,6-— ^ amino-1,4-benzyl are oxidized, followed by purification by column chromatography to obtain the melting point Ondansetron is 227.5 ° C -229 ° C. GB 2220352, EP 385517, and EP 276559 patents also describe the preparation of ondansetron related to Example 7 of the above-mentioned patent, and obtain melting points consistent with this example. Other methods of preparing ondansetron have also been described in the literature. The ondansetron produced by these methods has the following melting point: in the patent EP 22 1 629, followed by purification by column chromatography, the ondansetron is obtained in 21 Decomposed at 5 ° C -216 ° C; in EP 2 1 9929 patent, and then purified by column chromatography, the ondansetron is melted at 2 16 ° C-2 1 8 ° C, and then reconstituted in methanol. Crystallized, the resulting ondansetron was melted at 227.5 ° C -228.5 ° C; and, finally, in the EP 2043 535 patent, followed by recrystallization in methanol, the ondansetron was obtained at 2 2 7 _ 2 2 8.5 200528100 ^ ° C melting. That is, ondansetron described in all of the above references has a very variable melting point ranging from 21 5 ° C to 234 ° C. After purification by column chromatography, its melting point is still variable, from 215 t to 229 ° C. After recrystallization in methanol, the melting point increases and is concentrated at about 230 ° C (227 ° C -234 ° C). International patent W 0 0 3 0 9 3 2 6 0 discloses two crystalline forms of basic ondansetron, one of which has a melting point similar to the above reference and the other has a higher melting point, which are called Α Shape and B-shape. Form B • Melting point is 244 ± 2 ° C and the X-ray powder diffraction pattern is characterized by the following peaks-11.0; 11.2; 14.9; 15.5; 15.9; 16.5; 20.6; 21.4; 23.1; 23 5; 24.2; 24.7; 24.8; 25.8; 26.9; 28.1.20. It is prepared by dissolving basic ondansetron in ethanol or methanol at reflux temperature and then cooling. Form A is characterized by X-ray powder diffraction pattern, which has the following peaks: 11.0; 11.2; 14.8; 15.4; 16.4; 20.6; 21.4; 23.2; 24.1; 24.7; 25.4; 25.9; 26.7; 27.8 ° 2 0. Form A was prepared by recrystallizing ondansetron in Ν, Ν · dimethylformamide and recrystallizing ondan | cionone in 1-butanol. The polymorphs of the disclosed ondansetron are prepared on a scale of only a few grams or a maximum of 1.1 kilograms. In addition, although only a small amount of the product was obtained, the volume of the solvent needed was very large (to produce the largest amount of ondansetron mentioned above, that is, 1.1 kg, requiring 60 liters of solvent), thus hindering its large-scale production. It is therefore proposed to obtain novel and stable ondansetron polymorphs and methods for preparing the products on an industrial scale. [Abstract] 200528100.

'Beneficially' E-forms can also be prepared by reproducible methods on an industrial scale ', which produces the most desirable form of ondansetron on the market and is therefore the preferred form. The X-ray powder diffraction pattern is obtained via κ α! Rays of CU, which uses the INELCPS-120 device with a Ge single light meter and a Lindemann glass capillary with a sample system located at a diameter of 0.5 mm in the emission geometry. in. The error that determines the peak position at φ can be evaluated as ± 0.05 ° 20. It is also possible to distinguish the differences between C, D, and E-shaped polymorphs in the low-frequency region (between 15 and 150 cm ·) of Raman spectra, as shown in Figure 4. The Raman spectra of the C-shaped and D-shaped objects are relatively similar to each other, and the spectra clearly show the difference from the E-shaped objects. Therefore, Raman technology is not suitable for distinguishing C-shaped and D-shaped objects, although it can be used as a region between the two-shaped and E-shaped objects. The Raman spectrum uses a Job in-Y von T64000 with argon laser set φ It was prepared and measured using an excitation wave of 514.5 nm and a laser power between 30 and 35 mW. The three polymorphs of the present invention exhibit melting points in the range of 240-247 ° C. The melting point was determined by DSC based on the melting point peak, which was performed using an aluminum crucible with a hole cover at a heating rate of 10 ° C / min. Considering that the melting points of the three polymorphs of the present invention are similar, and that 2-methylimidazole is released when the basic ondansetron is melted, the melting point cannot be regarded as a feature that distinguishes the three polymorphs of the present invention. The following is a detailed description of the methods for preparing three types of C-, D-, and E-shaped polymorphs of the present invention. Form c is obtained by adding a precipitation solvent to a saturated solution of basic ondansetron at room temperature. In particular, Form C can be prepared by the following methods, including: a) preparing a saturated solution of basic ondansetron in dichloromethane at room temperature; b) crystallizing by adding C5-C7 alkane Precipitation; and c) recovering the crystalline form. Preferably, the C-C7 alkane is selected from n-hexane or n-pentane. Φ D forms can be prepared by the following methods, including:-a) dissolving basic ondansetron in Ci-C4 alcohol under reflux; _ b) adding a third -butyl-methyl-ether followed by Cooling; and c) recovering the crystalline form. Preferably, the alcohol is methanol. The invention also provides a method for manufacturing an E-shaped article. The method includes: a) dissolving ondansetron hydrochloride in a mixture of Ci-C3 alcohol and water; b) precipitating basic ondansetron by basifying the solution; φc) filtering out the Solid and washed with water; d) suspending the water-wetted solid obtained in stage c) in methanol with stirring under reflux; and e) recovering the crystalline form. Preferably, the Ci-Ca alcohol is methanol. The alkalization in stage b) can be performed by adding sodium hydroxide, potassium hydroxide or ammonia. Preferably, the alkalization in stage b) is performed by adding an aqueous ammonia solution. Advantageously, ammonium chloride is used as a residue to produce ammonium chloride as a residue, which is easier to dissolve in water than sodium chloride or potassium chloride -14-200528100 _ and alcohols and is therefore easier to remove. Advantageously, this method allows the E-form to be obtained in a completely reproducible manner on an industrial scale. Furthermore, since basic ondansetron does not need to be completely soluble in alcohol, it is not completely soluble in the solvent, and it can obtain more products with a very small amount of solvent compared with the prior art. Form E can also be prepared on a laboratory scale by: a) dissolving basic ondansetron in Ci-C4 alcohol under reflux; φ b) adding ethyl acetate followed by cooling And concentrated by slow evaporation at room temperature; and c) recovering the crystal form. Preferably, the C-C4 alcohol is methanol. The recovery of any of the polymorphs of the present invention is performed by filtering out the solid and drying it using a conventional method. In the present invention, "alcohol" means methanol, ethanol, n-propanol, isopropanol, and n-butanol. φ In the present invention, "C5-C7 alkane" means n-pentane, n-hexane, and n-heptane. The basic ondansetron and ondansetron hydrochloride as starting materials for preparing the polymorph of the present invention can be prepared by any method described in the literature. Preferably, it is prepared according to the general method described in the patent ES 2 0 4 3 5 35, the industrial application of the patent is to use hydrochloric acid as a catalyst and a mixture of isopropanol and water as a solvent. Ondansetron can be isolated directly as the hydrochloride. The basic ondansetron can be sequentially obtained by basifying a solution of the hydrochloride. -15- 200528100 The subject of the present invention is a pharmaceutical composition containing a therapeutically effective amount of any of the polymorphs of ondansetron C, D or E and an appropriate amount of at least one excipient. The composition provided by the present invention can be administered by any appropriate route, but is preferably administered orally or parenterally. Compositions for parenteral or topical administration can be in the form of injectable solutions, intravenous solutions, infusions, suppositories, or transdermal systems. Pharmaceutical compositions for oral administration can be solids such as troches or capsules, which can be prepared in a conventional manner with pharmaceutical acceptable excipients, or can be liquids such as aqueous or oil solutions, syrups, tinctures, emulsions or suspensions Liquid, which can be prepared according to conventional methods and pharmaceutically acceptable additives. Lozenges and injection or intravenous solutions are the preferred forms of oral and parenteral administration, respectively. A particularly preferred pharmaceutical form for administration of Ondansetron in the C, D, and E forms is an oral disintegrating tablet (also known as an oral dispersing agent (buccodispersable)). Oral dispersible lozenge refers to an uncoated phial lozenge administered orally, which has the advantage of disintegrating quickly before swallowing. Various types of technology are available for making such lozenges and are known to those skilled in the art. The best technology is disclosed in International Patent Application No. WO 03 103629. The pharmaceutical form may contain any of the C, D, and E polymorphs in a dose of 2-10 mg. Excipients used in the form of lozenges may include diluents, disintegrants, wetting agents, lubricants, colorants, flavoring agents, or other conventional adjuvants, in accordance with conventional pharmaceutical practice. Therefore, typical lozenge excipients include, for example, lactose, microcrystalline cellulose, corn starch, hypromellose, magnesium stearate, -16- 200528100 _ polyethylene glycol, polyvinylpyrrolidone, mannose sugar. The injection formulation of the present invention includes, preferably an aqueous solution, and conventional excipients for injection formulations include sodium citrate, citric acid, sodium chloride, and water for injection.
