The entire text of the prior application is incorporated into this application by reference. Technical Field
[0002] The present invention belongs to the field of pharmaceutical compositions, and in particular relates to a solution-type pharmaceutical composition of a phenol derivative, a preparation thereof, and a use thereof. Background Art
[0003] Autoimmune inflammatory diseases, such as psoriasis, atopic dermatitis, seborrheic dermatitis and other skin diseases. Among them, psoriasis is commonly known as psoriasis. Psoriasis is a common chronic, inflammatory, systemic disease induced by the interaction of multiple factors such as genetic factors, environmental factors, and immune factors. It has a long course of disease, is difficult to treat, and is prone to relapse. Some cases are almost lifelong and have a great impact on the patient's physical health and mental state. The common sites of onset are the scalp, sacrum, extensor side, flexor side and wrinkles of the limbs. Nearly 2 / 3 of the patients have onset of the disease in the hair area, especially the scalp is a common site for psoriasis. Studies have shown that 50% to 80% of psoriasis patients have skin lesions involving the scalp.
[0004] Seborrheic dermatitis (SD) is a chronic papulosquamous, superficial inflammatory skin disease that occurs in the area of sebum secretion. The typical rash is dark red, yellow-red spots formed by the fusion of follicular papules, covered with greasy scales or scabs, and may be accompanied by varying degrees of itching. SD is a chronic, recurrent inflammatory skin disease, usually manifested as a red scaly rash. The incidence rate in healthy people is 5%, of which 70.3% occurs on the head, common in infants, adolescents and adults. Seborrheic dermatitis refers to a disease of the scalp. The difference between this disease and simple dandruff is that it has erythema as a sign of inflammation, the degree of scalp flaking is greater and sometimes accompanied by itching and burning, and eczema occurs in other parts of the body. The disease can occur in the form of plaques, but often affects the entire scalp and exceeds the hairline, often including the forehead, around the neck and both ears. In severe cases, the scalp may become secondary infected, and changes may appear as a spongy texture, with blisters and crusts that may ooze. Seborrheic dermatitis also frequently occurs in infancy and usually resolves spontaneously at 8-12 months of age. Scalp changes in infants include erythema, flaking of the scalp, and occasional blisters and crusts that may resolve spontaneously within a few weeks, recur intermittently, or persist throughout childhood. These changes are often accompanied by similar lesions around the eyelids, nose, and ears. The condition then frequently recurs after adolescence and can persist throughout life, even with the potential for more severe symptoms. Approximately 1-3% of the population suffers from the disease. The etiology and pathogenesis of SD are still unclear, with the complex interaction of Malassezia, keratinocytes, and immune responses playing a crucial role in the onset of SD. Seborrheic dermatitis shares some of the same pathogenic factors as inflammatory skin diseases such as atopic dermatitis, such as the regulation of factors that stimulate keratinocyte proliferation and differentiation, and disruption of the skin barrier. Atopic dermatitis usually manifests as a Th2 immune response, with elevated levels of interleukin (IL)-4 and IL-13, while seborrheic dermatitis is mainly a Th2 and Th17 response, with elevated levels of IL-4, IL-17, and IL-8.
[0005] Current treatments for seborrheic dermatitis include simple anti-inflammatory drugs (such as topical hormone preparations, calcineurin inhibitors), supplemented with skin moisturizing skin care products, but the efficacy is low; and symptoms are prone to recurrence after drug discontinuation.
[0006] The treatment of psoriasis aims to control symptoms and improve the quality of life, including topical medications, systemic medications and phototherapy. Topical medications are the first-line basic treatment and are suitable for more than 90% of patients. Topical preparations mainly include creams, ointments, gels, etc. However, the commonly used dosage forms of topical medications (creams, ointments, gels, etc.) are difficult to use due to the following reasons: the sebaceous glands of the scalp are dense and active, the bioavailability of lipophilic creams will be affected by the sebaceous glands and hair follicles, and the treatment effect is poor. In addition, due to the obstruction of hair, these preparations will inevitably be applied to the hair during medication, which not only causes a waste of drugs, but is also often difficult to wash, resulting in a greasy appearance of the hair, an unpleasant odor, etc., and poor patient compliance with medication; making it difficult to use topical medications at the site of hair disease and ineffective.
[0007] Therefore, providing a stable and / or safe pharmaceutical composition / preparation to improve the problems of difficulty in medication, poor therapeutic effect, poor patient medication compliance, etc. in treating the above-mentioned diseases is something that technicians in this field have long been committed to solving.

[0115] Example 8 In vitro skin permeation test of Examples 1-5
[0116] The intradermal retention of Examples 1 to 5 was tested according to the following method.
[0117] Experimental methods:
[0118] Take the sample of Example 4 and the control group (commercially available Benvimod cream, Guangdong Zhonghao Pharmaceutical Co., Ltd., trade name: The in vitro permeation test of 1% belimumab was carried out to evaluate the intradermal retention and cumulative permeability. Porcine skin (thickness 0.8-1.0 mm) was mounted on a LOGAN System 918 vertical diffusion cell, with 1.77 cm exposed. 2 surface area. The diffusion cell was connected to a multichannel pump at a speed of 600 rpm, and the receiving fluid was normal saline (0.9% sodium chloride solution). Each cell was placed in a heating manifold to balance the temperature to ensure that the skin surface temperature was 32°C (at least 30 minutes before administration). The sample load was 0.3g. The receiving fluid was collected at 4, 8, 12, 16, and 24 hours to measure the active ingredients that penetrated through the skin. At the end of the 24-hour sampling, the skin was wiped with a cotton swab to remove any residual test sample that was considered not to penetrate the skin. The skin layer was cut into pieces and methanol was added for ultrasonic extraction of the drug. The recovered drug concentration was used to calculate the amount of retention in the skin.
[0119] Test results such as Figure 1 As shown, the intradermal retention amounts of Example 1, Example 2 and Example 3 were significantly lower than those of Example 4 and Example 5, and Example 4 was determined to be used as the optimized formula for subsequent screening.
[0120] Example 9 Optimization of Antioxidant
[0121] The antioxidant propyl gallate in Example 4 was replaced with butylated hydroxytoluene, and the stability of the new formulation was further observed. The specific formulation is shown in Table 2 below:
[0122] Table 2
[0123]
[0124]
[0125] a) Stability comparison:
[0126] The same amount of the composition of Example 4 and the composition of Example 9 were weighed into a liquid phase light-shielded sealed vial, and a total of 3 groups were set up. They were placed in room temperature and 60°C environments respectively, and the physical and chemical stability of the samples at 0 days, 60°C for five days, and 60°C for ten days was observed and measured by liquid phase. The specific results are shown in Table 3. The results show that the new impurities of RRT2.19 were detected in Example 9 at high temperature for 5 days and 10 days, while no new impurities appeared in Example 4. Example 4 has better stability than Example 9.

[0135]
[0136] Example 11 Intradermal retention and cumulative permeation test
[0137] According to the following method, Example 4 and the control group (commercially available Benvimod cream, manufacturer: Guangdong Zhonghao Pharmaceutical Co., Ltd., trade name: Intradermal retention and cumulative permeation of belimumab (content: 1%).
[0138] Experimental methods:
[0139] The samples of Example 4 and the control group were subjected to in vitro permeation tests to evaluate the intradermal retention and cumulative permeability. Porcine skin (thickness 0.8-1.0 mm) was mounted on a LOGAN System 918 vertical diffusion cell, exposing 1.77 cm 2 surface area. The diffusion cell was connected to a multichannel pump at a speed of 600 rpm, and the receiving fluid was PBS (pH 7.4). Each cell was placed in a heating manifold to balance the temperature to ensure that the skin surface temperature was 32°C (at least 30 minutes before administration). The sample was added at a dose of 10 mg of the test sample per square centimeter. The receiving fluid was collected at 2, 4, 8, 20, and 24 hours to measure the active ingredients that penetrated through the skin. At the end of the 24-hour sampling, the skin was wiped with a cotton swab to remove any residual test sample that was considered not to penetrate the skin. The skin layer was cut into pieces and methanol was added to ultrasonically extract the drug. The recovered drug concentration was used to calculate the amount of retention in the skin.
[0140] The test results are as follows Figure 2 and Figure 3 As shown, the intradermal retention and cumulative permeation amount of Example 4 are superior to those of the control group.
[0141] Example 12 Optimization of thickener
[0142] The applicant considered that the use of thickeners in the prescription may increase the viscosity of the drug solution and may affect the in vitro transdermal effect of the preparation, thereby affecting the patient's compliance with the preparation. The optimized prescription is shown in Table 5:
[0143] Table 5
[0144]
[0145] The viscosity of the formulation with sodium carboxymethylcellulose, i.e., Example 4, was significantly increased, and the patient compliance was poor; the formulation without sodium carboxymethylcellulose, i.e., Example 12, could be evenly dispersed on the skin, had low fluidity, and had good patient compliance.
[0146] Using the in vitro transdermal test procedure in Example 11, the in vitro transdermal conditions (including the average cumulative permeation amount and the skin retention amount per unit mass) of Example 4 and Example 12 were observed. The test results are shown in Table 1. Figure 4 and Figure 5 It can be seen that the retention amounts of the in vitro transdermal experiments of Example 4 and Example 12 are similar, and are slightly higher than those of the control group (commercially available Benvimod cream, Guangdong Zhonghao Pharmaceutical Co., Ltd., trade name: The content of benvimod: 1%), while the average cumulative permeation amount of Example 12 (the sample without sodium carboxymethylcellulose) was lower than that of Example 4 and the control group, and was only half of that of the control group. Therefore, the safety risk of the sample in Example 12 was reduced.
[0147] Example 13 Stability Test
[0148] The same amount of the composition of Example 12 was weighed into a light-shielded sealed vial and subjected to an accelerated test (40°C ± 2°C / 75% ± 5% RH). The specific results are shown in Table 6. The results show that the composition of Example 12 met the quality standards after 6 months of accelerated testing and had excellent stability.
[0149] Table 6
[0150]
[0151] The method for measuring the relevant substances is as described in Example 9.
[0152] Content determination method: Use octadecylsilane bonded silica gel as filler; use water as mobile phase A, acetonitrile as mobile phase B, and perform gradient elution according to the table below; the flow rate is 1.0 ml per minute; the column temperature is 30°C; the detection wavelength is 220 nm; and the injection volume is 25 μl.
[0153]
[0154] Example 14 Pharmacokinetic Test
[0155] Bama miniature pigs were percutaneously administered with the composition of Example 12 with a benvimod content of 1% and a control group (commercially available benvimod cream, Guangdong Zhonghao Pharmaceutical Co., Ltd., trade name: The skin pharmacokinetic properties of the common active ingredient benvimod in the two were investigated, and the differences between the two were compared.
[0156] Six Bama miniature pigs were selected, half male and half female. 10 μL / cm 2 Example 12 Composition and 10 mg / cm 2 After 2 doses in the control group (10h interval between doses), the skin of the dosing area was cut at 1, 2, 4, 6, 8, 12, 24, 36, 48, and 72h after the last dose (according to the design, the doses were given at different time points, and the dosing skin was cut after each group reached the end point at the same time). After wiping the surface ointment with alcohol, the stratum corneum was repeatedly removed with tape. The skin of the blank area was taken as the 0h point, the stratum corneum was repeatedly removed with tape, and stored at -20℃. The concentration of benvimod in the skin was determined by HPLC-MS / MS, and the PK parameters were calculated using the non-compartmental model of DAS3.3. Statistical analysis was performed using SPSS.
[0157] The results are shown in Table 7. After the Bama miniature pigs were topically administered with the composition of Example 12 having a bevimod content of 1% and the control group, the exposure of bevimod in the skin of the composition group of Example 12 was about 3.26 times that of the control group, and AUC (0-t) They were 669±187h*μg / g and 205±39.2h*μg / g respectively.

[0161] Example 15 Sensitization Test
[0162] The Buehler test was performed in adult guinea pigs to evaluate the local sensitization potential of the pharmaceutical compositions of Examples 4 and 5.
[0163] Experimental methods:
[0164] 60 healthy adult guinea pigs, half male and half female, were randomly divided into a negative control group, a positive control group, a low-dose group (Example 4, 1%) and a high-dose group (Example 5, 2%) according to sex and weight using the software TOXSTAT2006. There were 10 guinea pigs in each of the negative control group and the positive control group (half male and half female), and 20 guinea pigs in each of the low-dose group and the high-dose group (half male and half female). Before administration, the animals were prepared with electric clippers to cut the skin and hair on both sides of the back spine, 3×3 cm on each side. 2 .
[0165] Sensitization: 0.2 mL / animal of the test substance was administered to the left side of the depilatory area on the 0th, 7th, and 14th days, respectively. Filter paper was attached to the groove of the blank plaster, and the test substance was contained in the filter paper and applied to the administration site, and then sealed and fixed with non-irritating medical adhesive tape. The blank plaster and filter paper were removed after about 6 hours. The animals in the negative control group were administered with 0.9% sodium chloride injection, the animals in the positive control group were administered with 2% 2,4-dinitrochlorobenzene (ultrasonic preparation with 80% ethanol), and the animals in the low-dose group (Example 4) and the high-dose group (Example 5) were administered with the corresponding concentrations of the Example composition (1%, 2%).
[0166] Challenge: On the 14th day after the last sensitization, 0.2 ml / guinea pig of each group was given the test substance on the right side of the hair removal area (prepared with 0.2% 2,4-dinitrochlorobenzene, acetone solution), and the test substance was removed about 6 hours later. The allergic reaction symptoms were observed and recorded 1 hour and 24 hours after sensitization and 24 hours and 48 hours after challenge.
[0167] The results showed that under the experimental conditions, after adult guinea pigs were given the composition at different concentrations (1%, 2%) for multiple times, the Buehler test evaluation results were negative, indicating that as the concentration increased, there was still no sensitization effect on the skin.
[0168] Example 16 Clinical efficacy of seborrheic dermatitis
[0169] In a prospective, randomized, 8-week clinical trial, the spray composition prepared in Example 12 (treatment group) was applied to the skin of subjects with seborrheic dermatitis twice a day. The control group used the matrix component of Example 12 without benvimod and applied it to the affected area twice a day. The changes in the erythema index and desquamation index of seborrheic dermatitis were significantly improved in the second week and continued until the 8th week. By the 8th week, the changes in the erythema index of the treatment group decreased by 81.81%, and the changes in the desquamation index decreased by 83.70%; while the changes in the erythema index of the control group decreased by 38.46%, and the changes in the desquamation index decreased by 37.44%. From Table 8 and Figure 6 and Figure 7 The clinical efficacy of the AhR agonist benvimod in the treatment of patients with seborrheic dermatitis can be shown.
