Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of pharmaceutical preparations, and in particular to a pharmaceutical composition comprising a benzonitrile derivative. Background Art
[0002] The storage conditions of drugs are a reflection of the stability of the drugs in the drugs. Drugs or crystal forms with lower melting points generally have relatively poor stability and need to be stored at lower temperatures, while drugs or crystal forms with higher melting points have better stability and can generally be stored at room temperature. The reasonable processing temperature of the preparation should also be reasonably formulated according to the thermal stability of the drug. The thermal degradation of drugs is usually closely related to their melting points, and the degradation reaction will occur rapidly after exceeding the melting point by 20°C. Both fatty liver and cancer require long-term medication. The requirement of low-temperature storage will add a lot of inconvenience to the patient's long-term medication and may lead to missed doses or improper storage, which may affect the treatment effect and may cause delays or recurrences of the disease. In addition, low-temperature refrigeration conditions also require special cold chain transportation tools and long-term refrigerators, which bring additional costs to the commercial development of the product. Therefore, in order to better meet clinical and commercial needs, it is necessary to find a stable drug preparation and preparation method that can be stored at room temperature. Such a preparation will not only greatly increase the in vivo and in vitro dissolution of the active ingredient, but more importantly, enable it to be stored at room temperature. The molecular formula of the compound represented by formula (I): C 24 H 24 N4O3, its structural formula is as follows:
[0003]
[0004] The equilibrium solubility of the crystalline form III and the crystalline form VI of the compound represented by formula (I) in different media without the addition of surfactant is shown in Table 1, indicating that the equilibrium solubility of the raw material of the compound is pH-dependent, and it is necessary to adopt a reasonable solubilization method to increase its dissolution in vivo and in vitro.
[0005] Table 1 Equilibrium solubility of the compound represented by formula (I) in media with different pH values
[0006]
[0007]
[0008] In addition, the compound shown in formula (I) is slightly unstable at a high temperature of 60°C. After 15 days of acceleration, the total impurities increased by 0.31%. The auxiliary material polyethylene glycol 6000 is unstable for GL01 under high temperature conditions. Specifically, after 15 days of acceleration at 60°C, the total impurities may increase by 2.9%, and the related substances have a larger increase. The reason is that the melting point of polyethylene glycol 6000 is relatively low (DSC test results show that the melting point of polyethylene glycol 6000 is 58.6°C). After 15 days of acceleration at 60°C, polyethylene glycol 6000 is semi-solid. Polyethylene glycol 6000 may undergo condensation reaction with the compound shown in formula (I) at high temperature, and condense with the hydroxyl and secondary amine therein to form unknown impurities.
[0009] Therefore, there is still a need to develop a formulation that will allow a pharmaceutical composition comprising a compound of formula (I) to be stably stored for a long period of time at 25°C to 60°C and under conditions of high relative humidity, and have significantly better dissolution effects.

[0070] Example
[0071] 1. Screening of solubilizing excipients
[0072] The present invention screens the types of solubilizing excipients by taking improving the solubility of GL01 in various dissolution media as an evaluation index.
[0073] Considering that the solubility of GL01 API is pH-dependent, the solubilization effects of several conventional solubilizing excipients on GL01 were investigated. They were formulated according to Table 2 and added to 250 ml of pH 6.8 phosphate buffer, respectively. The mixture was shaken in a constant temperature shaker at 37°C, and samples were taken at 2 hours and 24 hours, respectively. The dissolution percentage of GL01 is shown in Table 2.
[0074] Table 2 Study on the solubilization effect of multiple conventional solubilizing excipients on GL01
[0075]
[0076]
[0077] From the results in Table 2, we can see that compared with other excipients, polyvinyl pyrrolidone VA64 (trade name VA64) can significantly improve the solubility of GL01 in pH 6.8 phosphate buffer. VA64) and polyvinyl caprolactam-polyvinyl acetate-polyethylene glycol graft copolymer (trade name ) for subsequent experiments.
[0078] 2. Screening of different solubilizing excipients and different processes
[0079] Method 1: Usually, the drug is transported through the stomach with a lower pH value (pH of about 1.0-4.5) in the human gastrointestinal tract, and then transported to the small intestine with a higher pH value (pH of about 4.5-6.8) for absorption. In order to more truly reflect the dissolution of GL01 in vivo, the present invention selects more stringent dissolution conditions for research. The specific operation is to refer to the enteric-coated preparation method 1 of the fourth part 0931 dissolution and release determination method of the Chinese Pharmacopoeia 2020 edition. First, stir 750ml of pH1.0 hydrochloride buffer at 75 rpm for 1 hour, then add 250ml of sodium phosphate solution to adjust the medium to pH6.8, and perform a dissolution test (hereinafter referred to as the pH1.0 and then pH6.8 dissolution method).
[0080] Method 2: From the solubility data in Table 1, it can be seen that under pH 6.8, the equilibrium solubility of GL01 is relatively low, and this pH condition corresponds to the small intestine, the absorption site in the body, which is representative. The specific operation is based on the second method of the paddle method in the fourth general rule of the 2020 edition of the Chinese Pharmacopoeia 0931 Dissolution and Release Determination Method. The medium is pH 6.8 phosphate buffer, so this condition was selected for the dissolution test (hereinafter referred to as the pH 6.8 dissolution method).
[0081] In order to improve the ability to distinguish the dissolution conditions, the rotation speed was selected to be a more stringent 50 rpm.
[0082] The 10 mg GL01 preparations prepared by different solubilizing excipients and different processes were investigated. The formulation processes are shown in Tables 3 and 4.
[0083] Table 3 10 mg GL01 preparations prepared by different solubilizing excipients and different processes 1 to 3
[0084]
[0085]
[0086] Table 4 10 mg GL01 preparations prepared by different solubilizing excipients and different processes 4 to 6
[0087]
[0088] The dissolution study of the preparation prepared by the above prescription was carried out, and the results were as follows Figure 1 and Figure 2 As shown in Table 3 and Table 4, the dissolution results of the mixture of GL01, polyvinyl pyrrolidone VA64 and polyethylene glycol 6000 have obvious dissolution advantages after hot melt extrusion granulation, so the hot melt extrusion process and its formulation were subsequently optimized.
[0089] In addition, although the equilibrium solubility of typical crystalline form III and crystalline form VI of GL01 API in pH 1.0 and pH 2.0 hydrochloric acid solutions for 48 hours is relatively high (as shown in Table 1), the dissolution data of GL01 API direct capsule filling shows that the dissolution rate of GL01 is relatively low, and it was not completely dissolved in the 2-3 hour dissolution test.
[0090] 3. Determination of solid dispersion formulation process
[0091] The compatibility results of raw materials and auxiliary materials reveal that polyvinyl pyrrolidone VA64 and GL01 are stable under all conditions. The present invention attempts to add a small amount of polyethylene glycol 6000 to the polyvinyl pyrrolidone VA64 carrier to reduce the glass transition temperature (Tg) of the solid dispersion, thereby reducing the temperature of hot melt extrusion, because too high a hot melt extrusion temperature may cause degradation of the raw material. Comparing the effect of the amount of polyethylene glycol 6000 added on the hot melt extrusion effect, it is found that with the increase in the amount of polyethylene glycol 6000, the extrudate gradually changes from clear and transparent to turbid and opaque, and finally becomes opaque and waxy. The transparency of the extruded material is used as the basis for judging whether the solid dispersion is made.
[0092] The prescription ratio and process parameters of the hot melt extrusion process of GL01 were explored. The hot melt temperature, extruder torque, screw speed, and transparency of the extrudate were used as process evaluation indicators. The solubilization effect of the solid dispersion on GL01 during the dissolution process, the degradation of related substances, and the risk of GL01 amorphous transformation were used as quality control evaluation indicators. The parameters were studied and the results are shown in Table 5.
[0093] Table 5 Exploration of hot melt extrusion process prescription ratio and process parameters of GL01
[0094]
[0095]
[0096] The feasibility of the process was investigated and found to be:
[0097] (1) The feasible temperature range of the hot melt extrusion heating zone is 130℃~160℃. If the temperature is as low as 120℃, the extrudate is opaque and the torque is large, and the equipment cannot operate normally; (2) API and polyvinyl pyrrolidone VA64 are prepared in a weight ratio of 1:5, 1:10, and 1:15. When an appropriate amount of polyethylene glycol 6000 is added, the material can be extruded. However, if polyethylene glycol 6000 is not added, a higher hot melt extrusion temperature is required, which may cause high-temperature thermal degradation of GL01; if excessive polyethylene glycol 6000 is added, the extrudate is opaque. In YF6021009, the ratio of polyvinyl pyrrolidone VA64: polyethylene glycol 6000 is 10:1, and it is found that the extrudate is not completely transparent. The final study found that the range of polyvinyl pyrrolidone VA64: polyethylene glycol 6000 is more suitable in the range of 20:1~30:1; (3) The feasible screw speed is 20~150rpm.
[0098] Quality control indicator evaluation:
[0099] (1) Dissolution of the extrudate after crushing and tableting:
[0100] API and polyvinylpyrrolidone VA64 were mixed at a weight ratio of 1:5, 1:10, and 1:15, and then an appropriate amount of polyethylene glycol 6000 was added. The batch numbers were YF6021008, YF6021010, and YF6021007. The successfully prepared GL01 solid dispersion was cooled and crushed, and powders smaller than 35 mesh (500 μm) were weighed and mixed with the additional excipients according to the prescription in Table 6 to prepare tablets for dissolution curve comparison. The results are shown in Figure 3 shown.
[0101] Table 6 Prescription of GL01 tablets in batches YF6021007, YF6021008 and YF6021010
[0102]
[0103]
[0104] The dissolution results showed that prescription 10 (batch number YF6021010) with a prescription ratio of API: polyvinyl pyrrolidone VA64: polyethylene glycol 6000 of 1:10:0.5 had better dissolution ability. Prescription 7 (batch number YF6021007) may be affected by the dissolution due to the excessive dosage of polyvinyl pyrrolidone VA64. During the disintegration process, a large amount of polyvinyl pyrrolidone VA64 showed excessive viscosity. Prescription 8 (batch number YF6021008) may be affected by the dissolution due to the low dosage of polyvinyl pyrrolidone VA64, which was not enough to completely dissolve GL01.
[0105] (2) Study on the crystal transformation risk of amorphous APIs produced by hot melt extrusion solid dispersions:
[0106] The GL01 preparation is composed of amorphous solid dispersion powder after hot melt extrusion, cooling and grinding, and added silicified microcrystalline cellulose SMCC90, mannitol M100, cross-linked polyvinylpyrrolidone XL-10 and sodium stearyl fumarate. In the tablet, GL01 is only present in the solid dispersion powder. Therefore, the study of amorphous solid dispersion powder can effectively eliminate the interference of added excipients and improve the sensitivity of detection.
[0107] When solid dispersion powder is accelerated under wet and hot conditions, the provision of water molecules and external energy will increase the loosening of the copolyvidone polymer chain, thereby increasing the activity of the drug or excipient in the carrier system.
[0108] API and polyvinylpyrrolidone VA64 were mixed in a weight ratio of 1:5, 1:10, and 1:15, and then an appropriate amount of polyethylene glycol 6000 was added. The batch numbers were YF6021008, YF6021010, and YF6021007. The successfully prepared GL01 solid dispersion was pulverized after cooling. It is intended to explore the stability of the morphology of GL01 in the solid dispersion through accelerated investigations under multiple conditions. The crystal form detection results of the solid dispersion under multiple accelerated conditions are shown below.
[0109] Among them, the XRPD results of the hot melt extrusion process on day 0 are as follows Figure 4 As shown, the hot melt extrudates are all in an amorphous state.
[0110] In summary, the hot melt temperature, extruder torque, screw speed and transparency of the extrudate were used as process evaluation indicators, and the solubilization effect of the solid dispersion on GL01 in the dissolution process, the degradation of related substances and the risk of GL01 amorphous transformation were used as quality control evaluation indicators. The optimal formula was determined to be GL01: polyvinyl pyrrolidone VA64: polyethylene glycol 6000 in a weight ratio of 1:10:0.5, which could obtain a hot melt extrudate with controllable quality and stable process.
[0111] 4. Confirmation of tablet formulation process
[0112] Based on the solid dispersion formulation process development, 10 mg GL01 tablets were developed and determined with dissolution curve, related substances and stability as indicators. The optimized formulation composition is shown in Table 7.
[0113] Table 7 Unit dose prescription composition of 10 mg GL01 tablets
[0114]
[0115] Tablets (10 mg tablets: batch YF6021015-10) prepared by the optimized formulation process were studied for dissolution curves in various dissolution media. The results in different media are shown in Tables 8 to 11. From the results, it can be seen that the 10 mg tablets can be dissolved more than 85% in 15 minutes in the four dissolution media at a low speed of 50 rpm without any surfactant, and all have good in vitro rapid dissolution effects.

[0126] 5. In vivo study of tablets for formulation confirmation in beagle dogs
[0127] This study aims to compare the effects of different dosage forms of GL01 on pharmacokinetics in beagle dogs given a single oral dose, and the results are shown in Table 12. The experimental design is to use 3 beagle dogs, intravenous injection of 0.5 mg / kg, oral administration of 10 mg / tablet / dog, oral administration of 10 mg / capsule / dog, and single administration in a cycle of 7 days.
[0128] Table 12 Comparative study results of 10 mg tablets, 10 mg capsules, PO and IV administration in beagle dogs
[0129]
[0130]
[0131] Among them, the 10mg tablet (batch number YF6021015-10) refers to the unit dose prescription composition of 10mg GL01 tablets in Table 7; the prescription information of GL01 capsules (batch number YF60JN001) refers to the 10mg GL01 preparations prepared by different solubilizing excipients and different processes in Table 4.
[0132] The above results show that: (1) The average bioavailability of 10 mg tablets is 60.3%, and the average exposure is 6815 hr*ng / mL, and the data have good parallelism. (2) In contrast, GL01 capsules have a lower average bioavailability of 13%, and an average exposure of 1431 hr*ng / mL, indicating that the absorption of the capsule formulation is significantly worse than that of the tablets. The bioavailability of 10 mg capsules is only about 1 / 5 of that of 10 mg tablets, and there is a significant difference (p<0.01); (3) GL01 is metabolized slowly in beagle dogs and has a longer half-life.
[0133] 6. Screening of dissolution conditions with differentiated strength for 10 mg GL01 preparation
[0134] In vivo experiments on beagle dogs found that the bioavailability of 10 mg capsules was only about 1 / 5 of that of 10 mg tablets. Two methods were selected: pH 6.8 phosphate buffer and more stringent dissolution conditions (pH 1.0 and then pH 6.8 dissolution method) to investigate the dissolution behavior of GL01 tablets and capsules. The results are as follows: Figure 5 and Figure 6 The dissolution curves of 10mg GL01 tablets and capsules in pH 6.8 phosphate buffer can more truly reflect the difference in bioavailability of the two in beagle dogs. At 30-45min, the dissolution rates of 10mg GL01 tablets and capsules in pH 6.8 phosphate buffer match the bioavailability, and the dissolution rate of 10mg capsules is about 1 / 5 of that of 10mg tablets.
[0135] In summary, the dissolution conditions determined were pH 6.8 phosphate buffer, 50 rpm; the evaluation standard was greater than 75% in 45 min.
