Description

Pharmaceutical composition comprising amorphous tegoprazan and method for preparing the same

[0001] The present invention relates to a pharmaceutical composition comprising amorphous tegoprazan and a method for preparing the same.

[0002] Amorphous tegoprazan is a solid state that lacks regular arrangement and is thermodynamically unstable due to its high energy levels. Therefore, it is prone to crystalline transformation over time, and is particularly unstable under high temperature and humidity conditions, preventing it from maintaining its amorphous state and further accelerating crystallization.

[0003] There are three methods for producing or maintaining an amorphous state. First, the solid dispersion method is a method for producing an amorphous solid dispersion by dissolving or suspending a hydrophobic drug together with a hydrophilic matrix. This method can produce a solid dispersion using a fluidized bed processor, a cylindrical granulator, a high-speed rotary granulator, and spray drying. Second, there is the hot-melt method, which produces a solid dispersion by heat-melting a hydrophobic drug, a hydrophilic matrix, and a surfactant without using a solvent. Third, there is milling, a mechanical crushing method that reduces the degree of crystallinity, converting the regular arrangement of crystals into an irregular arrangement to produce an amorphous form.

[0004] However, a method for ensuring that a pharmaceutical composition containing amorphous tegoprazan maintains a stable amorphous form has not yet been discovered, and in particular, a method for preparing a composition that prevents conversion to a crystalline form and stably maintains an amorphous form even under harsh or accelerated conditions is not known.

[0159] Experimental example

[0160] Experimental Example 1. Measurement of Tegoprazan by Differential Scanning Calorimetry

[0161] The phase transition temperatures of tegoprazan raw material in crystalline form A, crystalline form B, and amorphous form were measured using differential scanning calorimetry (DSC). Differential scanning calorimetry is a method for measuring the amount of heat released or absorbed when a sample is heated or cooled over a specific temperature range, and can be used to characterize the thermal properties of a material or to measure the temperature at which specific phase transitions, including glass transition temperature, melting point, and crystallization, occur. The results are shown in Figures 1a to 1c, and it was confirmed that amorphous tegoprazan had no specific phase transition value.

[0162]

[0163] Experimental Example 2. Measurement of X-ray powder diffraction spectrum of Tegoprazan

[0164] X-ray powder diffraction spectra were measured for crystalline form A, crystalline form B, and amorphous form of the raw material of tegoprazan. X-ray powder diffraction spectra are obtained by irradiating a sample with specific X-rays generated from an X-ray tube, and the crystalline phases in the sample are diffracted at unique angles according to Bragg's law. The angle and intensity at which the X-rays are detected are expressed as unique values ​​that characterize the corresponding crystalline phase. The specifications of the X-ray powder diffraction spectrum were set to analyze the sample using a 4kW X-ray generator, a Cu 1.8kW (Max. 60kV 60mA) X-ray tube, a vertical goniometer (scan range 1.5<2θ<140, minimum increment: 0.0001°), a PIXcel3D (0D, 1D, 2D) detector, and a Reflection-Transmission Spinner with a 45 position sample changer (5-axes (chi, phi, x, y, z) cradle) as a sample stage. The results are shown in Figs. 2a to 2c, and it was confirmed that amorphous tegoprazan had no specific 2θ value.

[0165] Meanwhile, according to the above Manufacturing Example 6, a composition containing amorphous tegoprazan that does not contain a mesoporous silica-based compound was prepared, and the change in crystal form of the composition under accelerated conditions was measured using an X-ray powder diffraction spectrum. The test results are as shown in FIGS. 4a to 4d, and it was confirmed that the composition containing amorphous tegoprazan prepared only with a water-soluble polymer had a specific 2θ value at which it was converted to a crystalline form after one month of acceleration, and thus was not maintained in an amorphous form.

[0166]

[0167] Experimental Example 3. Differential scanning calorimetry and X-ray powder diffraction spectra under harsh conditions

[0168] In order to select the optimal manufacturing method for preparing a pharmaceutical composition containing amorphous tegoprazan, granules prepared by the direct tableting method (Comparative Example 2-2), wet granulation method (Comparative Example 3-1), and spray-drying method (Comparative Example 4-2) were placed in containers, and amorphous tegoprazan was measured by DSC and XRD under harsh conditions to determine the change in phase transition temperature and crystal form. Under harsh conditions, the sample storage container was kept open at 40°C and 75% RH (relative humidity), and under conditions of 60°C, the sample storage container was kept closed. The results are shown in Table 7, and it was confirmed that the amorphous form was maintained in the pharmaceutical composition containing amorphous tegoprazan prepared by the direct mixing method and the spray-drying method.

[0171] Experimental Example 4. Stability Evaluation of Pharmaceutical Compositions Containing Amorphous Tegoprazan

[0172] Amorphous tegoprazan was prepared according to the compositions of Examples 3, 5, 6 and 8 of Manufacturing Example 5, and an excipient, a disintegrant and a lubricant were mixed with a pharmaceutical composition to prepare a tablet, and the tablet coated with the coating agent was stored for 4 weeks under harsh conditions and 6 months under accelerated conditions to confirm the change in crystalline form. The sample was placed in a storage container and stored in a closed state at 60°C under harsh conditions and in an airtight state at 40°C and 75% RH (relative humidity) under accelerated conditions for 6 months, and the change in crystalline form was confirmed by X-ray powder diffraction spectrum. The results are shown in Table 8 and Figures 3a to 3l below, and it was confirmed that all of the peaks observed in the crystalline form were maintained because the peaks observed in the crystalline form did not appear even when the storage conditions were changed, thereby maintaining the amorphous form of tegoprazan.

[0175] Experimental Example 5. Content Test

[0176] The content changes of samples stored for 4 weeks under harsh conditions and 6 months under accelerated conditions were confirmed. The samples were stored in storage containers at 60℃ in a closed state under harsh conditions and at 40℃, 75% RH (relative humidity), and sealed for 6 months under accelerated conditions. A content test was conducted on tablets containing amorphous tegoprazan manufactured according to the compositions of Examples 3, 5, 6, and 8 to confirm the content changes during the storage period. The sample analysis was performed using high-performance liquid chromatography (HPLC), with an ultraviolet spectrophotometer (measuring wavelength 262 nm) as the detector, a column filled with octadecylsilylated silica gel, and the gradient conditions of mobile phase A and mobile phase B were used. Mobile phase A was a 0.01 mol / mL ammonium acetate buffer: acetonitrile mixture (19:1), and mobile phase B was acetonitrile. The results are shown in Table 9, and it was confirmed that the content of the pharmaceutical composition including amorphous tegoprazan manufactured by the manufacturing method of the present invention was stably maintained within the standard even under harsh and accelerated conditions.
