Definitions
- the present invention relates to new uses of montmorillonite, and in particular to the use of montmorillonite in the prevention and treatment of colds in the preparation of medicaments.
- montmorillonite in medicine is administered through the digestive tract, mainly for the treatment of gastrointestinal diseases.
- the new use of montmorillonite disclosed in the Chinese patent approved in 2007 is that the treatment of chronic renal failure diseases is also treated by digestive tract administration. So far, there have been no reports of treatment of diseases by other modes of administration.
- Montmorillonite is a typical 2:1 layered silicate mineral containing water of crystallization, and has many excellent properties such as high dispersibility, suspension, swellability, cohesiveness, adsorption, and cation exchangeability.
- montmorillonite As a medicinal herb, montmorillonite has a long history. After oral administration, the drug can evenly cover the entire surface of the intestine. It has a high positioning ability and can last for 6 hours.
- montmorillonite can adsorb a variety of pathogens and endotoxin in the digestive tract, fix it on the surface of the intestine, and then excrete it with the peristalsis, thus avoiding damage to the body by various pathogens and endotoxin. '
- the sweet soil is non-toxic, the main medicine and the bacteria are poisoned, and the hot soup regulator is finally served.
- the sweet soil is bentonite (mainly composed of montmorillonite), which can be widely used to treat acute and delayed diarrhea, and treat esophagitis, gastritis, colitis, and irritable bowel syndrome. Because it is not easy to absorb after montmorillonite clothing, it does not enter the blood circulation. It is safe and non-toxic during application.
- the clinical use for the treatment of pediatric diseases has been widened in recent years.
- Chinese patent ZL200510082757. 0 discloses the application of montmorillonite in the treatment of chronic renal failure.
- Chinese patent ZL03121876. 8 discloses the application of montmorillonite in the treatment of hyperthyroidism and bad breath.

- concentration of montmorillonite in the preparation of a medicament for preventing and treating colds is, per 100 ml of montmorillonite.
- the content of montmorillonite in the aerosol is 5-20 grams.
- the method of using a montmorillonite spray to prevent and treat a cold is: the patient's nasal cavity is cleaned, the head is kept at an angle perpendicular to the ground or forward, and the nozzle of the montmorillonite spray drug container is placed in the nasal cavity. Each nostril is sprayed with 1 3 each time, each spray 0. 1-0. 2 liters, spray 2 - 4 times a day.
- the method of preventing and treating influenza by using montmorillonite nasal drops is as follows: The patient's nasal cavity is cleaned, the head is tilted back so that the nostrils face upward, and the medicine is dripped into the nostrils, and each nostril is dropped 2 - 3 drops, each drop 0. 0625 liters, 2-4 times a day, the medicine drops into the nose and pinch the nose several times, and keep the nostrils up for 5 minutes, so that the drug is in full contact with the nasal mucosa.
- the cold of the present invention includes the common cold and influenza.
- the common cold is a mild and self-limiting disease that is often caused by parainfluenza, rhinovirus, respiratory syncytial virus, coxsackie virus, and coronavirus.
- People are exposed to the secretions of the respiratory secretions containing a large amount of virus by infecting the surface of the environment with viral secretions.
- the virus invades the upper respiratory tract, causing changes in the flora of the upper respiratory tract and the inflammatory response of the host, damage to the host respiratory epithelium and matrix proteins, allowing bacteria to invade normal sterile areas such as the sinus, middle ear and tracheobronchial, etc.
- Antihistamines can cause adverse reactions such as mouth, nose, throat dryness, abdominal pain, diarrhea, vomiting, lethargy, and dizziness. Most non-steroidal anti-inflammatory drugs have an adverse effect on inhibiting hematopoietic function.
- the way to prevent the common cold is: block the spread, pay attention to isolation, air disinfection, avoid contact with pollutants, wash your hands and avoid natural contact between the hands, nose and hands; use drugs in the nasal cavity to block the virus from invading the nasal mucosa cells.
- Influenza referred to as influenza
- influenza is an acute respiratory infection caused by influenza A, B, and C viruses.
- Influenza A viruses often appear in popular form, which can cause a worldwide flow Row.
- Influenza B viruses often cause local outbreaks and do not cause a worldwide pandemic.
- Influenza C virus appears in sporadic form, mainly affecting infants and young children, and does not cause influenza epidemics.
- the flu virus only causes disease through the nasal cavity. It is mainly transmitted by air droplets and contact, and the injection of influenza virus into humans does not occur. The virus first invades the ciliated epithelial cells of the nasal mucosa, further enters the tracheobronchial bronchus, causing severe damage in the local area, causing extensive inflammation of the upper respiratory tract within 1-2 days.
- influenza virus After the influenza virus infects a small number of cells, a large number of virus particles are replicated, and then released, and then infected with other cells, causing the infection to spread.
- the clinical manifestations of flu are chills, fever, body temperature up to 38-40 ° C, headache, weakness, eye pain, body laziness, nausea, runny nose, stuffy nose, sneezing, etc., facial flushing and conjunctival hyperemia.
- the symptoms of systemic poisoning caused by the flu are caused by the destruction of the respiratory mucosa and the entry of some viruses and their products into the bloodstream. There has been no real breakthrough in influenza prevention. At present, the commonly used influenza virus vaccines in the world are purified, multivalent inactivated vaccines.
- the invention can prevent both the common cold and the influenza, and has no drug resistance, no toxicity and no side effects.
- montmorillonite After montmorillonite is added with water to make nasal drops or sprays or aerosols, montmorillonite passes through the particles. Through-expansion and inter-layer hydration, the particles are dispersed, the layers are peeled off, the negatively charged layer interacts with the end faces, and the cross-linking associates to form a hydrated gel. In addition to the remarkable adhesion, montmorillonite hydration gel can bind to the mucus on the upper respiratory tract surface, significantly enhance the cohesive force and viscoelasticity of the mucus, firmly cover the surface of the nasal mucosa, form an isolation protective film, and effectively block The virus invades the nasal mucosal cells. The use of montmorillonite nasal drops or sprays or aerosols can be used to prevent colds.
- montmorillonite nasal drops or spray or aerosol After the montmorillonite nasal drops or spray or aerosol enters the upper respiratory tract, it can cover the entire upper respiratory tract surface. Through adsorption and "card-type" gel structure, viruses, germs and bacteria that have entered the upper respiratory tract can be The toxins they produce are adsorbed, fixed, and then excreted with the sputum, causing them to lose their pathogenic effects and inhibit the replication and spread of the virus. The use of montmorillonite nasal drops or sprays or aerosols can be used to treat colds.

Description
技术领域
本发明涉及蒙脱石的新用途, 具体涉及蒙脱石在预防和治疗感冒的蒙 脱石在制备药物中的应用。
技术背景
目前, 蒙脱石在药物中的应用均是通过消化道给药, 主要治疗胃肠 道疾病。 2007年批准的中国专利公开的蒙脱石的新用途是治疗慢性肾功能 衰竭疾病也是通过消化道给药进行治疗, 到目前为止, 尚未有通过其他给 药方式治疗疾病的报道。
蒙脱石是典型的 2 : 1 型含结晶水的层状硅酸盐矿物, 具有高分散性、 悬浮性、 膨润性、 粘结性、 吸附性、 阳离子交换性等许多优良特性。 蒙脱 石作为药用具有悠久的历史, 口服后,药物可均匀地覆盖在整个肠腔表面, 具有极高的定位能力, 可维持 6小时之久。 用于治疗腹泻, 蒙脱石可吸附 多种病原体和消化道内毒素, 将其固定在肠腔表面, 而后随肠蠕动排出体 外, 从而避免多种病原体和消化道内毒素对机体的损伤。 '
我国唐代医学名著 《本草拾遗》 中记载: "甘土无毒, 主治草药及诸 菌毒, 热汤调节器末服之"。 甘土即为膨润土 (主要成分为蒙脱石), 可广 泛用于治疗急、 缓性腹泻, 治疗食管炎、 胃炎、 结肠炎、 肠易激综合症。 由于蒙脱石服后不易吸收, 不进入血液循环, 应用期间十分安全, 无毒性 反应, 近年用于儿科疾病治疗的临床用途不断被拓宽。
例如: 中国专利 ZL200510082757. 0公开了蒙脱石治疗慢性肾功能衰 竭的应用。 中国专利 ZL03121876. 8 公开了蒙脱石治疗甲亢, 口臭的应用 等。
发明内容
本发明的目的在于提供蒙脱石在制备药物中的应用, 通过上呼吸道给 药, 用蒙脱石预防和治疗感冒, 并提供用蒙脱石预防和治疗感冒的药剂类 型, 同时提供预防和治疗感冒的方法。
为实现上述目的, 通过以下技术方案来实现: 蒙脱石在制备预防和治 疗感冒药物中的应用, 感冒包括普通感冒和流行性感冒。 蒙脱石在制备预 防和治疗感冒的药物剂型是蒙脱石滴鼻液, 蒙脱石在制备预防和治疗感冒 的药物剂型是蒙脱石喷雾剂, 蒙脱石在制备预防和治疗感冒的药物剂型是 蒙脱石气雾剂, 蒙脱石制备预防和治疗感冒的药剂的浓度是, 每 100毫升 蒙脱石滴鼻液中蒙脱石的含量是 5-20 克, 蒙脱石在制备预防和治疗感冒 的药剂的浓度是, 每 100毫升蒙脱石喷雾剂中蒙脱石的含量是 5-20克, 蒙脱石在制备预防和治疗感冒的药剂的浓度是, 每 100毫升蒙脱石气雾剂 中蒙脱石的含量是 5- 20克。
采用蒙脱石制备喷雾剂和滴鼻液, 用于治疗甲型、 乙型及丙型流感病 毒引起的急性呼吸道传染病。
用蒙脱石喷雾剂予页防和治疗感冒的方法是: 将患者鼻腔清理干净, 头 部保持与地面垂直或向前倾斜的角度, 将蒙脱石喷雾剂药物容器的喷嘴置 入鼻腔内, 每个鼻孔每次均为 1 3喷, 每次喷 0. 1-0. 2亳升, 每日喷 2 - 4 次。
用蒙脱石滴鼻液预防和治疗流感冒的方法是: 将患者鼻腔清理干净, 头部向后倾斜使鼻孔朝上, 将药物滴入鼻孔, 每个鼻孔均滴 2- 3滴, 每滴 0. 0625亳升, 每日滴 2-4次, 药液滴入后捏鼻翼数次, 并保持鼻孔朝上 5 分钟, 使药物与鼻腔黏膜充分接触。
本发明所述感冒包括普通感冒和流行性感冒。
普通感冒是一种轻微和自限性的疾病, 常由副流感病毒、 鼻病毒、 呼 吸道合胞病毒、 柯萨奇病毒及冠状病毒等引起。 人通过接触环境表面有病 毒的分泌物, 吸入含大量病毒的呼吸道分泌物的空气被传染。 病毒侵人上 呼吸道, 导致上呼吸道正常定居的菌群改变和宿主的炎性反应、 损伤了宿 主呼吸道上皮和基质蛋白, 使细菌侵入正常时无菌的区域, 如鼻窦、 中耳 和气管支气管等, 使细菌沉淀到这些区域, 加上这些区域出口的梗阻和粘 膜清洁作用的损伤, 导致继发性细菌感染。 普通感冒的临床表现, 主要症 状为流涕、 鼻塞、 喷嚏、 咽喉痛、 头痛和咳嗽。 可能有低热, 其他不适包 括轻度眼痛、 嗅觉和味觉缺失、 耳堵感、 说话声有鼻音。 病程大约 1周, 约 1 / 4的病人可持续到 2周。 目前没有真正的 "治愈" 感冒药, 主要有 抗组胺药和非 体类抗炎药, 可以很好的缓解喷嚏、 流涕、 头痛。 抗组胺 药可致口、 鼻、 喉发干、 腹痛、 腹泻、 呕吐、 嗜睡、 眩暈等不良反应。 非 甾体类抗炎药大多数具有抑制造血功能的不良作用。 预防普通感冒的办法 是: 阻断传播, 注意隔离, 空气消毒, 避免接触污染物, 洗手和避免手鼻、 手眼自然接触; 鼻腔内使用药物阻断病毒侵入鼻黏膜细胞。
流行性感冒简称流感, 是由甲、 乙、 丙三型流感病毒分别引起的急性 呼吸道传染病。 甲型流感病毒常以流行形式出现, 可以造成世界性的大流
行。 乙型流感病毒常造成局部暴发, 不引起世界性大流行。 丙型流感病毒 以散发形式出现, 主要侵袭婴幼儿, 不引起流感流行。 流感病毒只有通过 鼻腔才会致病。 主要通过空气飞沫和接触传播, 将流感病毒注射于人则不 发病。 病毒首先侵入鼻粘膜的纤毛上皮细胞, 进一步进人气管支气管, 在 局部区域造成严重破坏, 在 1- 2d 内引起上呼吸道广泛炎症。 流感病毒感 染少数细胞后, 复制出大量的病毒颗粒, 释放后再感染其他细胞, 造成感 染扩散。 流感的临床表现有畏寒、 发热、 体温可达 38- 40°C、 头痛、 无力、 眼痛、 全身酸懒、 恶心、 流涕、 鼻塞、 打喷嚏等、 面部潮红和球结膜充血。 流感产生的全身中毒症状是由于呼吸道黏膜破坏, 部分病毒及其产物进入 血流造成。 在流感预防上至今还没有真正地突破。 目前国际上常用的流 感病毒疫苗为纯化的、 多价灭活疫苗。 当今所使用的有 3种类型, 各有利 弊。①全病毒粒灭活的(制备简单, 有时会引起不良反应); ②半裂解的(可 降低不良反应, 但制备过程繁琐); ③亚单位疫苗(安全性好, 但抗体应答 效果差, 造价高)。 疫苗株需随流感病毒株抗原的变异而及时更换, 否则 无法保证预防效果。 目前治疗流感的药物有金刚烷胺和金刚乙胺能特异性 的抑制甲型流感病毒的复制, 对乙型流感病毒无效, 这两种药物均有共同 的交叉敏感性或耐药性, 副作用为易产生神经毒性及易产生耐药性。 病毒 唑在体外实验中证实既能抗甲型也能抗乙型流感病毒, 但临床无明显抗病 毒作用和治疗效果。
本发明既可预防同时也可治疗普通感冒和流行感冒, 长期使用不产生 耐药性, 无毒、 无副作用。
蒙脱石加水制成滴鼻液或喷雾剂或气雾剂后, 蒙脱石通过颗粒间的渗
透膨胀和层间水化, 颗粒分散, 叠层之间发生剥离, 带负电的层面与端面 相互作用, 交联缔合形成水化凝胶。 蒙脱石水化凝胶除有显著的粘附性, 能与上呼吸道表面的粘液结合, 显著增强粘液的内聚力和粘弹性, 牢固地 覆盖于鼻粘膜表面, 形成隔离保护膜, 有效的阻断病毒侵入鼻黏膜细胞。 使用蒙脱石滴鼻液或喷雾剂或气雾剂, 可达到预防感冒的目的。
蒙脱石滴鼻液或喷雾剂或气雾剂进入上呼吸道后, 可覆盖在整个上呼 吸道表面, 通过吸附作用及 "卡房式"凝胶结构, 可将已进入上呼吸道的 病毒、 病菌及它们产生的毒素吸附、 固定, 而后随鼻涕排出体外, 使其失 去致病作用, 并能抑制病毒的复制和传播。 使用蒙脱石滴鼻液或喷雾剂或 气雾剂, 可达到治疗感冒的目的。
