Description

Technical Field

[0001] This invention relates to a traditional Chinese medicine preparation for the treatment of hemorrhoids and its preparation method. Background Technology

[0002] Hemorrhoids, also known as piles, are one of the most common anal diseases in clinical practice. The modern concept of hemorrhoids was proposed by the British scientist Thomson in 1975: hemorrhoids are pathological enlargement of the anal cushions in the lower rectum. Depending on their location, hemorrhoids can be classified as internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids. Internal hemorrhoids are considered to be pathological changes or displacements of the supporting structures, vascular plexuses, and arteriovenous anastomoses of the anal cushions (anal canal vascular cushions). External hemorrhoids are pathological dilation or thrombosis of the subcutaneous vascular plexus distal to the dentate line. Mixed hemorrhoids are a combination of internal and external hemorrhoids.

[0003] Traditional Chinese medicine believes that hemorrhoids are caused by external pathogenic factors, excessive hunger or overeating, or irregular eating habits, leading to deficiency and stagnation of qi and blood. Western medicine has no unified standard, with theories of anal cushion displacement and varicose veins. Mongolian medicine believes that hemorrhoids are caused by imbalance of the three elements of Hei, Xila, and Badagan. Literature: Li Xiaomin. Analysis of the efficacy of integrated traditional Chinese and Western medicine in the treatment of 130 patients with hemorrhoids [J]. Clinical Medical Engineering, 2010, 17(7):2. It is mentioned that the current Western medicine treatment mainly includes rubber band ligation, injection therapy and surgery, while the traditional Chinese medicine treatment includes the use of Chinese herbal decoctions and Chinese herbal fumigation. Literature: Xilin Tuya, Yu Lijun, Fu Haiqi, et al. Research progress in clinical treatment of hemorrhoids [J]. Journal of Baotou Medical College, 2022, 38(5):4. It also mentions external application, sitz bath, anal plugging, acupuncture and padding. Among them, the treatment of Chinese herbal decoctions has the advantages of strong targeting, painlessness and high safety, and is widely accepted by patients.

[0004] In the prior art, CN115887601A discloses a composition for hemorrhoids and its preparation method, relating to the field of traditional Chinese medicine technology. This composition for hemorrhoids includes: Citrus aurantium, rhubarb, Astragalus membranaceus, Gallnut, Nelumbo nucifera receptacle, Forsythia suspensa, Siraitia grosvenorii, Angelica sinensis, Curcuma zedoaria, Ligusticum chuanxiong, Taraxacum mongolicum, Phellodendron chinense, Lithospermum erythrorhizon, and borneol. This composition for hemorrhoids has a good therapeutic effect on hemorrhoids, showing significant efficacy against internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids. However, this product is for external use only and does not provide a comprehensive cure.

[0005] CN1970006A discloses a traditional Chinese medicine wine for treating hemorrhoids, which is made by soaking 31 traditional Chinese medicines such as astragalus membranaceus, red ginseng, cistanche deserticola, angelica sinensis, eucommia ulmoides, acanthopanax giraldii harms, human placenta, frankincense, scorpio, scolopendra, and pig's trotter in white liquor. It is convenient to take orally, does not affect normal work and life, and has a significant treatment effect. Although the usage method of this product is oral administration, the traditional Chinese medicine components are as many as 31 kinds, not only with high cost, but also the preparation method is relatively cumbersome.

[0041] Example 7: Clinical observation of the drug of the present invention for treating hemorrhoids 1. General Information A total of 35 patients were included, of whom 27 were male and 8 were female, with a male-to-female ratio of 3:1. The ages of the patients were as follows: 3 were 20-30 years old, 8 were 31-40 years old, 10 were 41-50 years old, and 14 were over 50 years old. Among them, 21 were government officials, senior executives and technical personnel, 9 were ordinary staff members, 2 were teachers, and 3 were drivers.

[0042] 2. Diagnostic criteria Symptoms include anal swelling, pain, recurrent bleeding during bowel movements (sometimes profuse bleeding), prolapse of the anal canal and rectal mucosa, fatigue, lower back pain, insomnia, and excessive dreaming. Hemorrhoids are classified into internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids. Clinical diagnosis is mainly based on the patient's clinical symptoms and digital rectal examination, without the need for special examinations.

[0043] Internal hemorrhoids are classified into four stages: Stage I internal hemorrhoids present with dripping or spurting bleeding during bowel movements. Stage II internal hemorrhoids present with bright red blood during bowel movements, and the hemorrhoids prolapse but can spontaneously reduce. Stage III internal hemorrhoids present with bright red blood during bowel movements, and the prolapsed hemorrhoids require manual reduction. Stage IV internal hemorrhoids present with small amounts of bright red blood during bowel movements, and cannot be manually reduced.

[0044] External hemorrhoids include four types: varicose external hemorrhoids, connective tissue external hemorrhoids, inflammatory external hemorrhoids, and thrombosed external hemorrhoids.

[0045] Varicose external hemorrhoids: These are soft, round or oval lumps formed at the anal margin due to congestion and varicose veins in the external hemorrhoidal plexus below the dentate line. Various factors that cause hemorrhoids can lead to varicose external hemorrhoids, including prolonged sitting or standing, chronic constipation, chronic diarrhea, sustained increases in abdominal pressure, and infection.

[0046] Connective tissue external hemorrhoids: These are caused by repeated episodes of chronic inflammation, leading to fibrosis and connective tissue hyperplasia of the skin around the anus, forming skin tags. They are primarily composed of hyperplastic fibrous connective tissue, with dilated blood vessels being rare. They can be single or multiple. They can also be a result of thrombosed external hemorrhoids or surgical remnants of anal surgery; infection can cause pain.

[0047] Inflammatory external hemorrhoids: caused by infection after anal injury, or by inflammation and edema of perianal skin tags caused by anal fissures.

[0048] Thrombosed external hemorrhoids: This is a common type of external hemorrhoid, often caused by excessive straining during bowel movements, strenuous activity, or violent coughing, leading to rupture of veins at the anal margin. Blood seeps into the connective tissue, forming a thrombus that creates a round or oval subcutaneous mass around the anus, accompanied by severe pain. Initially, it is soft, but hardens after a few days. If it becomes repeatedly infected, it can lead to connective tissue hyperplasia, forming connective tissue external hemorrhoids; if the infection worsens, it can form a perianal abscess.

[0049] Mixed hemorrhoids can present with symptoms of both internal and external hemorrhoids, including rectal bleeding and prolapse.

[0050] 3. Treatment methods The traditional Chinese medicine preparation uses the formula from Example 6. Take 50mL-100mL once a night, approximately 15 minutes before bedtime. For patients with more severe symptoms, such as rectal bleeding or incarceration, take an additional 50mL once a day in the morning. One course of treatment is 3 days, and two courses are recommended.

[0051] 4. Efficacy evaluation criteria Significant effect: No recurrence was observed after 3 months of observation following the cure of hemorrhoids.

[0052] Improvement: The diameter of the lump or hemorrhoids shrinks, the symptoms of rectal prolapse are reduced or disappear, the symptoms of incarceration are reduced or disappear, the symptoms of anal swelling and pain are reduced or disappear, and the symptoms of long-term and repeated bleeding during defecation are reduced or disappear. After treatment, the patient has three or more of the above conditions.

[0053] Ineffective: Those who do not meet the criteria for improvement.

[0054] Effective: Both those showing significant improvement and those showing improvement are considered effective.

[0055] Table 1. Observation of therapeutic effects after treatment

[0056] As shown in Table 1, during the two courses of treatment (6 days), 35 cases were treated with the drug of this invention. The results showed that 15 cases were significantly effective, 20 cases were improved, and 0 cases were ineffective. The effective rate was 42.86%, the improvement rate was 57.14%, and the total effective rate was 100%.
