Description

Technical Field

[0001] This invention belongs to the field of pharmaceutical technology and relates to a hydrocortisone compound ointment preparation for treating hemorrhoids. Background Technology

[0002] Hemorrhoids are a common disease located in the anal area, referring to the dilation and expansion of veins in the submucosa of the rectum, anal canal, and anal margin, forming soft, hemangioma-like lesions. Based on their location, they can be classified as internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids. Patients may experience symptoms such as pain, rectal bleeding, a feeling of heaviness or pressure, and prolapse, which seriously affect their health and quality of life.

[0003] There are many methods for treating hemorrhoids. Traditional Chinese medicine treatments include fumigation, external application, sitz baths, and rectal suppositories, often used for mild to moderate hemorrhoids. These can quickly relieve pain, but their effectiveness alone is not ideal, and they are often combined with Western medicine treatments. Western medicine treatments include internal and external therapies. Internal therapies use medication; external therapies are surgical treatments, which are the fastest way to treat hemorrhoids. With the continuous improvement of modern medical technology, some non-surgical therapies have emerged, such as laser and infrared therapy, which can also eliminate hemorrhoids, allowing traditional medicine to fully leverage its significant advantages in treating hemorrhoids. However, this method has disadvantages such as slow recovery, high recurrence rate, and postoperative bleeding, especially when treating severe hemorrhoids, as it may cause excessive tissue damage and affect recovery.

[0004] Relevant patent documents retrieved: Patent CN102579569A discloses a pharmaceutical composition for treating hemorrhoids, its preparation method, and its application. The technical solution comprises 80-20 parts berberine hydrochloride, 7-20 parts procaine hydrochloride, 1.5-4.2 parts hydrocortisone, 7-18 parts borneol, 3.5-6.5 parts menthol, and a lipid-soluble matrix to bring the total to 1000 parts. Compared with this application, it does not contain vasoconstrictors, chlorhexidine acetate, or allantoin, but it still contains borneol and berberine hydrochloride; furthermore, the content of hydrocortisone and menthol (or L-menthol) differs from that in this application.

[0005] Patent CN1813766A discloses a hemorrhoid ointment, which is prepared by sequentially adding 89%-98% petrolatum, 0.1%-0.9% nifedipine, 0.5%-4% hydrocortisone, 1%-6.04% lidocaine, and 0.01%-0.07% menthol into a sterile container and stirring until homogeneous. Compared with this application, it does not contain vasoconstrictors, chlorhexidine acetate, or allantoin, but it still contains nifedipine; in addition, the content of hydrocortisone and menthol (or L-menthol) in it is different from that in this application.

[0006] Patent CN102579457A discloses a compound tetracaine composition, its preparation method, and its application. The composition comprises the following active pharmaceutical ingredients: tetracaine, ephedrine, phenobarbital, diphenhydramine, hydrocortisone, and borneol; wherein the weight parts of each component are: tetracaine 20-40 parts, ephedrine 20-40 parts, phenobarbital 20-40 parts, diphenhydramine 10-25 parts, hydrocortisone 2-15 parts, and borneol 3-15 parts. Compared to this application, it does not contain chlorhexidine acetate or allantoin, but still contains tetracaine, ephedrine, phenobarbital, diphenhydramine, and borneol; furthermore, the content of hydrocortisone differs from that in this application.

[0007] Relevant non-patent literature retrieved: The literature, "A Study on the Effective Components of the Classic Formula Sanhuang Ointment and Its Therapeutic Effect on Experimental Hemorrhoids in Rats," discloses that this study used the classic Chinese formula Sanhuang Ointment as the research object, and used berberine hydrochloride, aloe-emodin, baicalin, coptisine, baicalin, and rhein as indicators. Combining single-factor experiments and response surface methodology, and based on the guidance of modern TCM theory and the traditional preparation method of *Yixin Fang*, the study optimized the preparation process (determining the optimal parameters such as soaking for 12 hours and frying for 60 minutes at 140℃) and established an HPLC fingerprint (calibrating 13... The study identified 6 peaks and used liquid chromatography-mass spectrometry (LC-MS) to identify 706 chemical components (41 with similarity exceeding 90%), clarifying their pharmacodynamic substances. Combined with network pharmacology, molecular docking (identifying core targets such as CGRP and component affinity), and animal experiments (mouse ear swelling and rat anorectal models), it was confirmed that Sanhuang Ointment can exert anti-inflammatory and hemorrhoid-treating effects by inhibiting inflammatory factors and promoting the secretion of healing-related cytokines. This provides a basis for its development into a stable and effective traditional Chinese medicine compound external preparation.

[0008] This document contains at least the following unresolved technical problems or defects: The formulation lacks stability, as evidenced by the following: In the literature "Study on the Effective Components of the Classic Formula Sanhuang Ointment and Its Use in Treating Experimental Hemorrhoids in Rats", only the relative standard deviation (RSD) value from 0 to 48 hours was measured. It did not verify whether the ointment was easy to spread on the skin surface, whether it clumped or separated, which directly affects the user experience and efficacy. It did not assess whether the ointment was sticky or easily absorbed after application. Poor skin feel may lead to decreased user compliance, indirectly affecting the treatment effect. It did not verify whether the formulation separated or precipitated through centrifugation tests (such as centrifugation at 3000 rpm for 30 minutes), which could not rule out the risk of physical instability after being subjected to force (such as shaking or vibration). This indicates that the stability of the formulation needs to be fully verified and improved. Summary of the Invention

[0084] 3. The hydrocortisone compound ointment formulations of prescriptions 1-2, 3-1 to 3-4 obtained by the above prescriptions and preparation methods were subjected to in vitro lidocaine release assay. The assay procedure is as follows: Apparatus: Vertical diffusion cell; Temperature: 32℃; Rotation speed: 600 rpm; Release medium: pH 6.8 phosphate buffer solution; Sample loading amount: 300mg (2mm quantitative loop); Artificial membrane: PES (polyethersulfone) pore size: 0.45μm; Medium volume: 10ml; Sampling time: 1h, 2h, 3h, 4h, 5h, 6h; Sampling volume: 1 ml; Replenishment volume: 1 ml; Diffusion cell orifice diameter: 15 mm; Diffusion cell orifice area: 1.77 cm² 2 ; HPLC chromatographic conditions using Agilent ZORBAX C18 (4.6×250mm, 5μm) column; acetonitrile-water (50:30) as mobile phase; flow rate 1.0 ml / min; detection wavelength 250 nm; column temperature 30℃; injection volume 10 μl.

[0085] The measurement results are as follows Figure 1 As shown, the results indicated that in the hydrocortisone compound ointment formulation of prescription 3-1, the cumulative permeation of lidocaine hydrochloride did not reach 15.00 μg / cm³ after 24 hours. 2 In prescriptions 1-2, 3-2 to 3-4, the cumulative permeation of lidocaine hydrochloride reached 20.00 μg / cm³ within 24 hours. 2 Therefore, the weight percentage of lidocaine hydrochloride is chosen to be 2%-4%.

[0086] Example 4 1. A compound ointment preparation of hydrocortisone for treating hemorrhoids. This embodiment provides prescriptions 1-2, 4-1 to 4-4.

After all the double dishes have been filled with the bottom layer, cover them with ceramic lids and wait for solidification before use.

[0094] (2) Bacterial layer: Take out the pre-tested Staphylococcus aureus, Escherichia coli, Bacillus subtilis, and Pseudomonas aeruginosa bacterial suspensions respectively, and use a sterile pipette (or sterile syringe) to draw 2 ml of bacterial suspension (0.5%) and add it to the culture medium that has been melted and kept warm in a water bath (48℃). Shake well to prepare the bacterial layer. Use a sterile wide-mouth pipette to draw 2 ml of culture medium with added bacteria, spread the culture medium evenly on the bottom culture medium, place it on a water platform, cover it with a ceramic tile lid, and let it solidify before use.

[0095] (3) Placing the steel pipe: Place the steel pipe into the stainless steel cup in the steel pipe holder, turn on the switch, place the double plate on the operating table of the steel pipe holder, align the interface, press the handle to make the steel pipe fall steadily on the culture medium. After the steel pipe is placed properly, let it stand and allow the steel pipe to sink and stabilize in the culture medium. Then add 0.1g of ointment of prescription 5-1, prescription 1-2, prescription 5-2, prescription 5-3 and prescription 5-4 respectively.

[0096] (4) Sample addition: Add ointments of prescriptions 5-1, 1-2, 5-2, 5-3, and 5-4 to a petri dish, ensuring the ointments are level with the top edge of the small steel tube. Incubate at 30°C for 8 hours. The results are shown in Table 8. Table 8

[0097] Chlorhexidine acetate is a broad-spectrum antibacterial disinfectant, mainly used to kill or inhibit bacteria, fungi, and other microorganisms. It can be used for disinfection of skin and mucous membrane surfaces. Test results showed that formulations 1-2, 5-2 to 5-4 exhibited good inhibitory activity against Staphylococcus aureus, Escherichia coli, and Streptococcus mutans, while formulation 5-1 showed poor inhibitory effect. Therefore, a weight percentage of chlorhexidine acetate of 0.02%-0.5% was selected.

[0098] Example 6 1. A hydrocortisone compound ointment preparation for treating hemorrhoids. This embodiment provides prescriptions 1-2, 6-1 to 6-4. The difference between the above prescriptions is that the allantoin content is different. The specific prescription ingredients (g) are shown in Table 9.

[0101] 3. After adding allantoin to the above prescription, observe the dispersion of allantoin in the matrix, and based on... Figure 2 Microscopic examination revealed that allantoin in prescription 6-4 comprised 1.5% by weight, with numerous particle clusters observed in the field of view. Therefore, an allantoin weight percentage of 0.05%-1% was selected.

[0102] Example 7 1. A compound ointment preparation of hydrocortisone for treating hemorrhoids. This embodiment provides prescription 7-1, which uses 10g of hydrocortisone butyrate to replace hydrocortisone in prescription 1-2. The specific prescription ingredients (g) are shown in Table 10.

[0123] Table 17

[0124] 2. Comparative Example 3 did not include chlorhexidine acetate; the preparation method was the same as in Example 1. Experiment 1: Verification of a rat anal swelling model The animals used in the experiment were 6-week-old SD rats, half male and half female.

[0125] The croton oil mixture was prepared using 1 part distilled water, 4 parts pyridine, 5 parts ether, and 10 parts 6% croton oil ether solution. To create the model, a cotton ball soaked in 0.16 mL of the croton oil mixture was inserted into the anus of a 6-week-old rat anesthetized with chloral hydrate for 40 seconds, thus obtaining a croton oil-induced anal swelling model in rats.

[0126] After successful model establishment, the rats were immediately divided into groups, and drug administration began. The drugs were administered intrarectally using cotton swabs. The dosage for prescriptions 1-2, 8-1, 9-1, and comparative examples 1, 2, and 3 was 0.2 g / kg. Based on a rat weight of 300 g, the dosage per rat was 0.06 g. The normal control group and the model group received the drug via saline solution using cotton swabs. Administered the drugs three times daily for 14 consecutive days.

[0127] The diameter of the swelling in the entire perianal tissue was measured using vernier calipers before film formation and 2 and 4 days after film formation and drug administration. The mean of the anal diameter at different time points after modeling and the anal diameter before modeling was used as an indicator of the degree of swelling. Since the anal swelling of the model rats disappeared after 4 days, the anal diameter was no longer measured after 4 days.

[0128] The results are shown in Table 18.

[0129] Table 18 Effect of croton oil on anal swelling degree in rats (±S, mm, n=10)

[0130] Note: && p<0.05 The model group was compared with the normal control group; * p<0.05 The examples were compared with the model control group; # p<0.05 The examples are compared with the comparative examples.

[0131] Conclusion: Preliminary experiments on anal swelling using ointments with different raw material compositions showed a significant difference in the degree of anal swelling between the model group and the normal group, indicating successful model establishment. Compared with prescriptions 1-2, 8-1, and 9-1, prescriptions 1-2, 8-1, and 9-1 showed significant therapeutic effects on croton oil-induced anal swelling in rats, reducing the degree of anal swelling. Compared with comparative examples 1, 2, and 3, comparative examples 1, 2, and 3 showed almost no significant difference in the croton oil-induced anal swelling model compared to the model control group, failing to reduce the degree of anal swelling. Compared with comparative examples 1, 2, and 3, prescriptions 1-2, 8-1, and 9-1 showed significant therapeutic effects on croton oil-induced anal swelling in rats, reducing the degree of anal swelling.

[0132] Therefore, it can be seen that prescriptions 1-2, 8-1 and 9-1 have significant therapeutic effects on the rat anal swelling model and can reduce the degree of anal swelling.

[0133] Experiment Example 2: Results and Analysis of a Rat Anal Ulcer Model The animals used in the experiment were 6-week-old SD rats, half male and half female.

[0134] 1. Route of administration The test sample is used clinically for perianal or intraanal application; therefore, this study uses rectal administration in rats to simulate clinical administration conditions and obtain evaluation data.

[0135] 2. Dosage design and basis The proposed clinical dosage for each prescription is 2g three times daily. Based on the equivalent dose coefficient for rats and humans, this is approximately 2 × 0.018 × 5 ≈ 0.2g / kg. This experiment uses the clinically equivalent dose of 0.2g / kg. Assuming each rat weighs 300g, the dosage per rat is 0.06g, administered three times daily.

[0136] The clinical dosage and administration of Mayinglong Musk Hemorrhoid Ointment are as follows: 2-3 times daily, 2-3g each time. Based on the equivalent dose coefficient between rats and humans, the formula is: 2 × 0.018 × 5 ≈ 0.2g / kg. Assuming each rat weighs 300g, the dosage per rat can be set at 0.06g, administered 3 times daily.

[0137] 3. Animal identification after grouping Each animal was identified using animal tagging and box tagging methods.

[0138] 3.1 Animal Marking Each group of animals was numbered 1-10, and different parts of the animals' fur were rubbed with picric acid for marking. See Table 19 for details.

[0139] Table 19 Animal Markings

[0140] 3.2 Box Label After grouping the animals, different groups are labeled with different colored tags. The tags include: project number, tag number, sex, group, animal number, project leader, contact number, and experiment start and end dates. The completed tags are hung on the front of the enclosure.

[0141] 4. Acetic acid-induced rat anal ulcer model experiment 4.1 Model Preparation Filter paper with an inner diameter of 6 mm was made using a punch. After being fully soaked in 99.0% acetic acid solution (overnight soaking), the filter paper was placed around the anus of 50 membrane-forming rats to ensure close contact between the filter paper and the perianal skin and mucous membrane. One filter paper was used each time, and the filter paper was replaced once every 0.5 min for each rat, for a total of 1 min per rat.

[0142] 4.2 Animal grouping Group design: A total of 6 groups were set up, namely normal animal group, model control group, prescription 1-2 group, prescription 8-1 group, prescription 9-1 group, and positive control group.

[0143] Number of animals: 10 animals per group, totaling 60 animals; Sex ratio: 50% male and 50% female; Grouping method: The anal diameter was measured the day after modeling, and the samples were evenly grouped according to the anal diameter. See Table 20 below for specific grouping information.

[0144] Table 20 Dosing Regimen and Grouping Information

[0145] Note: The first digit of the animal number represents the group, the second letter represents acetic acid (C), and the last two digits represent the animal serial number.

[0146] 4.3 Animal administration After grouping, medication was administered. For each prescription (1-2, 8-1, and 9-1), the dosage was 0.2 g / kg. 0.06 g of each prescription was thoroughly mixed with the medication and then applied to the anus using a cotton swab. For the positive control group, the dosage was 0.06 g / animal. For the normal and model groups, the dosage was applied with a cotton swab soaked in physiological saline. Administered three times daily for 14 consecutive days.

[0147] 4.4 Indicator Testing 4.4.1 Weight Measurement Weigh yourself once a week.

[0148] 4.4.2 Ulcer Score Measurement The healing of the ulcer was observed at 2, 4, 8, 10, 12, and 14 days after medication, and an ulcer score was assigned (assignment criteria: exudate criteria: 3 points for ulcer exudate; 2 points for a small amount of ulcer exudate; 1 point for eschar and basic healing; 0 points for complete healing. Redness and swelling criteria: 3 points for redness and swelling ≥1mm and extending beyond the ulcer surface; 2 points for the edge protruding above the skin; 1 point for barely visible redness and swelling; 0 points for no redness or swelling). Photos were taken at each observation.

[0149] 4.4.3 Ulcer surface and measurement The long and short diameters of the ulcer were observed at 2, 4, 8, 10, 12, and 14 days after medication, and the product of the long and short diameters was taken as the ulcer area.

[0150] 4.4.4 Pathological and histological examination Testing time: End of test Animals tested: All surviving animals Detection method: After euthanasia by chloral hydrate anesthesia, skin around the anus and the ulcer site was excised, fixed in formalin, and stained with hematoxylin and eosin (HE) for pathological histological examination. 5. Results Analysis 5.1 Weight Before administration, there was no significant difference in body weight between the three dosage groups (Ma Yinglong Hemorrhoid Ointment, Prescription 1-2, Prescription 8-1, and Prescription 9-1) and the model group (P>0.05). After modeling, the model group showed slower weight gain compared to the normal group. On days 7 and 14 after administration, the body weight of the Ma Yinglong Hemorrhoid Ointment group and the test sample groups (Prescription 1-2, Prescription 8-1, and Prescription 9-1) was basically the same as that of the model group (p>0.05). The results are shown in Table 21.

[0151] Table 21 Effect of acetic acid on body weight in rats with anal ulcer model ( (±S, g, n=10)

[0152] Note: & p < 0.05, compared with the normal control group.

[0153] 5.2 Ulcer Score Compared with the normal control group, all animals developed perianal exudation and swelling after modeling. Compared with the model group, the perianal exudation and swelling of the Ma Yinglong Hemorrhoid Ointment and the three dosage groups (Prescription 1-2, Prescription 8-1, and Prescription 9-1) decreased from day 4 after administration, and the ulcer score gradually decreased. Statistically significant differences were observed between the Ma Yinglong Hemorrhoid Ointment and the three dosage groups (Prescription 1-2, Prescription 8-1, and Prescription 9-1) starting from day 8 (p < 0.01). Compared with Ma Yinglong Hemorrhoid Ointment, there were no significant differences in ulcer scores at any test point among the three dosage groups (Prescription 1-2, Prescription 8-1, and Prescription 9-1) (P > 0.05); the results are shown in Table 22.

[0155] Note: && p < 0.01, compared with the normal control group; *p<0.05, **p<0.01 Comparison between each treatment group and the model control group; p>0.05, compared with the positive control group for each dose group of prescriptions 1-2, 8-1, and 9-1.

[0156] 5.3 Ulcer area Normal rats have no perianal ulcers. In the model group, rats developed ulcers of varying degrees after modeling. The ulcers reached their final stage on day 8 after modeling, with an incidence rate of 90%. Some animals gradually recovered spontaneously afterward. However, by day 14 after modeling, 60% of the animals still had ulcers that had not healed spontaneously.

[0157] Compared with the model group, the number of animals with ulcers in the Mayinglong Hemorrhoid Ointment and the three dosage groups (Prescription 1-2, Prescription 8-1, and Prescription 9-1) was significantly reduced, and the ulcer area decreased significantly from day 8 of administration. By day 10, all animals in the Prescription 1-2, Prescription 8-1, and Prescription 9-1 groups had ulcers healed, with statistically significant differences in ulcer area (p < 0.05). However, at each time point after administration, there were no statistically significant differences between the three dosage groups (Prescription 1-2, Prescription 8-1, and Prescription 9-1) and the Mayinglong Hemorrhoid Ointment group (p > 0.05), but none of the animals in the Mayinglong Hemorrhoid Ointment group had ulcers healed; the results are shown in Table 23.

[0158] Table 23 Effects of different formulations on ulcer area in acetic acid-induced anal ulcer model rats (±S, mm) 2 (n=10)

[0159] Note: && p < 0.01, compared with the normal control group; *p<0.05, **p<0.01 Comparison between each treatment group and the model control group; p>0.05, compared with the positive control group for each dose group of prescriptions 1-2, 8-1, and 9-1.

[0160] 5.4 Pathological and histological examination Normal control group: The perianal skin and mucous membrane epithelial tissue structure is intact.

[0161] Model control group: Partial mucosal epithelial degeneration and necrosis can be seen, some tissue mucosal surfaces show exudation, interstitial tissue swelling, and submucosal capillary dilation and congestion.

[0162] Positive control group: Anal tissue damage was significantly improved, but telangiectasia and edema were still visible in the interstitial tissue.

[0163] Prescription 1-2 dose group: Significant improvement in anal tissue damage, no obvious mucosal epithelial and skin tissue degeneration and necrosis, no inflammatory cell infiltration and exudation, and no tissue edema.

[0164] Prescription 8-1 dose group: Significant improvement in anal tissue damage, no obvious mucosal epithelial and skin tissue degeneration and necrosis, no inflammatory cell infiltration and exudation, and no tissue edema.

[0165] Prescription 9-1 dosage group: The anal tissue damage was significantly improved, with no obvious degeneration and necrosis of mucosal epithelium and skin tissue, no inflammatory cell infiltration and exudation, and no tissue edema.

[0166] Therefore, it can be seen that the lesions in the model group were more obvious, indicating that the modeling was successful. The three dosage groups (Ma Yinglong Hemorrhoid Ointment, Prescription 1-2, Prescription 8-1, and Prescription 9-1) all showed varying degrees of improvement, with the Prescription 1-2, Prescription 8-1, and Prescription 9-1 showing more significant improvement than the Ma Yinglong Hemorrhoid Ointment group.
