  • Airway Inflammation including inflammation of the upper and lower respiratory tract, is the most important pathological change in many respiratory diseases.
  • the upper respiratory tract inflammation mainly refers to inflammation caused by diseases such as rhinitis, sinusitis, tonsillitis, adenoiditis and laryngitis.
  • the lower respiratory tract inflammation mainly refers to diseases caused by acute and chronic pneumonia, bronchitis, bronchitis and bronchial asthma. Inflammation. Since the upper and lower respiratory tracts are anatomically continuous, inflammation is rarely confined to a certain site.
  • Various experimental and clinical studies have confirmed that the upper and lower respiratory tract inflammatory responses are consistent and closely related, that is, the upper respiratory tract. Inflammation can affect the lower respiratory tract.
  • the possible contact mechanisms are: 1 the inflammatory response of the upper respiratory tract mucosa spreads directly down the respiratory tract; 2 through the trigeminal nerve and vagus nerve reflex; 3 due to posterior nasal drip, purulent nasal secretions and inflammatory mediators in nasal secretions, Cytokines and strong alkaline granule proteins produced by eosinophils are directly inhaled into the lower respiratory tract; 4 inflammatory mediators, cytokines and strong alkaline granule proteins produced by eosinophils circulate through the bloodstream to the lower respiratory tract.
  • cytokines and mediators are the major pro-inflammatory factors in the process of inflammation, mainly interleukin (IL), interferon- ⁇ (IFN), and tumor necrosis factor (TNF).
  • IL interleukin
  • IFN interferon- ⁇
  • TNF tumor necrosis factor
  • colony-stimulating factor (CSF) has been found to further chemotaxis of various inflammatory cells (eosinophils, neutrophils, lymphocytes, monocytes, macrophages, mast cells, etc.) into the respiratory mucosa. It migrates and causes mast cells to degranulate and release the medium again, leading to epithelial damage, etc. The damaged epithelial cells further produce various cytokines to produce inflammation.
  • the inflammatory response results in respiratory ventilatory and drainage disorders, disruption of mucociliary clearance, and invasion by pathogens (viruses, bacteria or fungi, etc.), further aggravating the inflammatory response.
  • airway hyperresponsiveness means that the trachea and bronchial tree are in an abnormally sensitive state, and thus Various stimuli exhibit a non-specific abnormal response, the airway diameter becomes smaller, and the resistance increases.
  • the mechanism of its involvement involves airway inflammation, epithelium caused by many inflammatory cells (mast cells and eosinophils, etc.) and their products. Cell damage, microvascular leakage, and autonomic mechanisms. These factors interact with inflammation to cause airway hyperresponsiveness.

  • Airway hyperresponsiveness can occur in diseases such as respiratory tract inflammation.
  • airway inflammation has been found to be associated with respiratory diseases. Chronic airway inflammation is more difficult to treat than acute airway inflammation. It is currently believed that airway inflammation is associated with or without transient airway infection due to pathogen infections (such as respiratory viruses). Responsive. Clinically, the following methods are generally used to treat various symptoms caused by respiratory inflammation: 1 Short-term use of histamine HI receptor antagonists to treat post-infection cough, such as desloratadine, cetirizine, but only temporarily relieved Symptoms; 2 preferred glucocorticoids, such as dexamethasone. Hormones are extremely beneficial for reducing inflammation, but their toxic side effects are large, and their long-term safety concerns limit their use; 3 use antibiotics.
  • antibiotics do not improve and cure various symptoms caused by respiratory inflammation unless it is diagnosed with respiratory inflammation and bacterial infection. If the anti-inflammatory treatment is not effective after infection, it will delay the disease and cause the abuse of antibiotics and the increase of drug resistance.
  • Ibuprofen is an optically active isomer of ibuprofen, which is 160 times more potent than levosome and 1.6 times more than racemic ibuprofen, with less gastrointestinal side effects and better tolerance, so right Ibuprofen is a better alternative to racemic ibuprofen.

It is mainly characterized by inflammation. If inflammation is not controlled, it may cause irreversible damage to the respiratory tract, leading to bronchiectasis or even respiratory failure.
  • ibuprofen sustained-release preparation can prevent cough caused by angiotensin-converting enzyme inhibitor, and the effective rate is 86.3 %.
  • the mechanism may be related to the reduction of synthesis and release of inflammatory mediators such as prostaglandins.

Description

右布洛芬左西替利嗪缓释双层片在治疗气道炎症中的用途 技术领域:
本发明涉及药学领域,具体涉及一种右布洛芬左西替利嗪缓释双层片在缓解 由气道炎症引起的各种不适症状方面的应用。
背景技术:
气道炎症 (Airway Inflammation) 包括上、 下呼吸道炎症, 是诸多呼吸道疾 病最主要的病理学改变。 其中上呼吸道炎症主要是指鼻炎、 鼻窦炎、 扁桃体炎、 腺样体炎和喉炎等疾病引起的炎症,下呼吸道炎症主要是指急慢性肺炎、气管炎、 支气管炎及支气管哮喘等疾病引起的炎症。 由于上、下呼吸道各部位在解剖学上 是相连续的,炎症很少只局限于某一部位, 多种实验和临床研究证实上、 下呼吸 道炎症反应具有一致性, 并密切相关, 即上呼吸道炎症可波及下呼吸道。其可能 的联系机制是:①上呼吸道粘膜的炎症反应直接向下呼吸道蔓延; ②通过三叉神 经和迷走神经反射; ③由于后鼻滴涕,脓性鼻分泌物和鼻分泌物中的炎性介质、 细胞因子和嗜酸粒细胞所产生的强碱性颗粒蛋白直接被吸入下呼吸道;④炎性介 质、 细胞因子和嗜酸粒细胞产生的强碱性颗粒蛋白经血循环至下呼吸道。
1、 气道炎症的发病机理
1 ) 炎症因子
研究表明, 细胞因子和介质是炎症过程中的主要促炎因子, 主要有白介素 (IL)、 γ2干扰素 (IFN) 、 肿瘤坏死因子 (TNF) 等。 近年来发现集落刺激因子 (CSF) 可进一步使多种炎性细胞 (嗜酸粒细胞、 中性粒细胞、 淋巴细胞、 单核细胞、 巨 噬细胞和肥大细胞等) 向呼吸道粘膜中趋化和移行,并再次引起肥大细胞脱颗粒 和释放介质, 导致上皮损伤等, 损伤的上皮细胞又进一步产生多种细胞因子产生 炎症。炎症反应的结果是导致呼吸道通气和引流障碍、粘液纤毛清除功能破坏和 病原菌 (病毒、 细菌或真菌等) 的侵袭, 从而进一步加重炎症反应。
2) 气道高反应性
气道高反应性的本质是指气管、支气管树处于一种异常敏感状态, 因而对于 各种刺激表现出一种非特异性的超常反应, 气道口径变小, 阻力增大, 其发生机 理涉及许多炎症细胞 (肥大细胞和嗜酸性粒细胞等) 及其产物引起的气道炎症、 上皮细胞受损、微血管渗漏及植物神经机制。这些因素与炎症相互作用共同引起 气道高反应性。 支气管哮喘、 病毒性上呼吸道感染、 慢性阻塞性肺疾病、 过敏性 鼻炎、 支气管扩张、 过敏性肺泡炎、 热带肺嗜酸性粒细胞增多症、 囊性纤维化、 结节病、 成人呼吸窘迫综合症等疾病引起呼吸道炎症均可出现气道高反应性。
2、 气道炎症的治疗药物
近年来发现气道炎症与呼吸道疾病有关,其中慢性气道炎症较急性气道炎症 更为难治, 目前认为是由于病原体感染(如呼吸道病毒等)引起气道炎症伴或不 伴短暂性气道高反应性所致。临床上一般采用以下几种方法治疗呼吸道炎症引起 的各种症状: ①短时使用组胺 HI受体拮抗剂治疗感染后咳嗽, 如地氯雷他定、 西替利嗪, 但仅能暂时缓解症状; ②首选糖皮质激素类药物, 如地塞米松。 激素 对减轻炎症反应是极为有益的,然而其毒副作用较大,对长期安全性的担忧使其 应用受限; ③使用抗生素。一般而言临床对抗感染治疗比较重视, 然而抗生素并 不能改善和治愈呼吸道炎症引起的各种症状, 除非确诊呼吸道炎症合并细菌感 染。 如果感染后抗炎治疗不得力, 既贻误病情,又造成抗生素的滥用和耐药性的 上升。
越来越多证据表明气道炎症的恶性循环是呼吸系统疾病的主要表现,如果得 不到及时治疗, 将对呼吸道造成不可逆性损害, 严重者将导致支气管扩张, 并最 终造成呼吸衰竭。通过抗炎疗法缓解气道炎症症状,对于减缓病程具有积极意义, 因此寻找疗效更强、副作用更小、又有良好耐受性的抗炎药物, 对于有效治疗气 道炎症具有重要的临床价值及社会意义。
3、 本品复方制剂的组方依据
1 ) 单方抗炎作用
① 右布洛芬
右布洛芬是布洛芬的光学活性异构体,其药效是左旋体的 160倍, 是消旋布 洛芬的 1.6倍, 且胃肠副作用更小, 耐受性更好, 因此右布洛芬是外消旋布洛芬 的较好替代药物。 由于右布洛芬上市较晚,研究报道更多的是关于布洛芬的抗炎 作用, 具体如下: 美国过敏与哮喘医学研究中心 2004年临床研究显示,布洛芬 /伪麻黄碱 /氯苯 那敏 (200/30/2 mg)可增强伪麻黄碱 /氯苯那敏 (30/2 mg)对季节性过敏性鼻炎的治 疗, 其中过敏性症状缓解程度增加 17%-22%,提示布洛芬可增强组胺 HI受体拮 抗剂阻止过敏性介质释放达到协同抗炎作用。
传统认为布洛芬的抗炎作用机制主要是抑制环氧合酶 (COX) 活性, 新近 研究证实布洛芬还可通过 COX非依赖性途径产生抗炎作用, 包括抑制核转录因 子 NFKB、激活核受体 PPARS/γ及热休克转录因子 -1而产生抗炎作用。余嘉璐及李 梅等临床研究报道显示, 呼吸道感染伴高热使用布洛芬,对全身炎症反应综合征
(SIRS) 患儿血清中炎症因子早期干预, 可避免炎症损伤加重, 副作用少, 经 济实用, 提示布洛芬通过抑制 TNF-cu IL-6、 IL-10等重要致炎因子的释放而产生 抗炎作用, 从而治疗 SIRS; 陈开泉报道布洛芬佐治小儿急性肺炎的疗效观察; 劳金泉报道布洛芬能对炎症的多种机制起作用而发挥非特异性抗炎作用,故在支 气管肺炎合并高热时应用疗效良好; 胡皓夫报道布洛芬可防止肺损伤,减少急性 呼吸窘迫综合征的产生, 美国 FDA 已批准布洛芬作为儿童抗炎性介质的唯一非 甾体抗炎药。故重症肺炎高热不退、中毒症状严重可应用布洛芬作为抗炎治疗措 施之一, 剂量: 每次 5〜10mg/ kg , 每天可用 3〜4 次, 可连用 3〜5 天; 王彩娟 报道肺囊性纤维化是一种以感染和损坏的恶性循环为特征的疾病, 主要表现为 炎症, 如炎症得不到控制, 可能会对呼吸道造成不可逆性破坏, 导致患者支气管 扩张甚至呼吸衰竭。 一项研究表明, 一日二次、 每次 20-30mg/kg的布洛芬对肺囊 性纤维化儿童患者的肺功能和营养均有效。基于这些研究结果, 囊性纤维化基金 会积极提倡将布洛芬作为抗炎药用于肺囊性纤维化儿童患者。朱一帆等临床研究 报道布洛芬缓释制剂可阻止血管紧张素转换酶抑制剂引起的咳嗽,有效率达 86. 3 %, 其作用机制可能与减少前列腺素等炎性介质的合成与释放有关。
综上所述, 布洛芬作为抗炎药物已逐渐应用于临床治疗呼吸道炎症相关疾 病,基于右布洛芬是布洛芬的光学活性异构体, 两者在药理作用及作用机制方面 的一致性, 无疑右布洛芬也具有抗炎作用。
② 盐酸左西替利嗪
盐酸左西替利嗪为第三代高选择性外周 HI受体拮抗剂,是西替利嗪的 R异 构体 (2001年在德国首次上市), 其对 HI受体的亲和力 (Kl=3.2nmol/L) 是西 替利嗪 (Kl=6.3 nmol/L) 的两倍。 与第二代抗组胺药比较, 盐酸左西替利嗪起 效较快, 肝脏和心脏蓄积少, 对 QT间期无明显影响, 且经肾脏以原型排出, 无 需肝脏代谢, 药物相互作用少, 因而耐受性好, 不良反应少, 优于西替利嗪。
国内外临床研究报道显示,盐酸左西替利嗪是目前为数不多的能够较好缓解 鼻充血、 改善鼻塞症状的抗组胺药, 优于地氯雷他定; 在改善流涕、 鼻痒、 打喷 嚏、 流泪、 咳嗽等症状方面较氯雷他定的作用更为持久和显著。 此外, 越来越多 临床数据表明, 西替利嗪或盐酸左西替利嗪能够有效快速控制感染后咳嗽(又称 感冒后咳嗽) 或哮喘症状。
感冒后咳嗽是指近期有明确呼吸道感染史, 且 X线胸片检查正常, 临床表现 为刺激性干咳, 多呈阵发性, 夜间为重、冷空气、灰尘环境、刺激性气体、运动、 烟雾等诱发或加重。 新版《咳嗽的诊断与治疗指南》 (2009)明确指出, 感染后咳 嗽类属于亚急性咳嗽(3-8周), 是慢性咳嗽病因之一, 多数慢性咳嗽病因与感染 无关, 经验治疗时应避免滥用抗生素, 而短时使用抗组织胺 HI受体拮抗剂治疗 感冒后咳嗽是临床方案选择之一。 寿志南、 刘润萍和王昀等对 40 例慢性咳嗽患 者经予盐酸西替利嗪治疗, 总有效率 85 %-89.1%, 明显优于抗感染及止咳化痰等 常规治疗, 病程大大縮短且不良反应少。 另有王华光等研究报道, 盐酸左西替利 嗪能够显著降低哮喘相关细胞因子的水平, 因此可能成为一种新的治疗哮喘的 药物。进一步研究证实盐酸左西替利嗪或西替利嗪具有独立于组胺阻断作用的重 要抗炎效应和较强的免疫调节活性, 能够抑制变态反应中多种炎症因子 (如 ICAM-K IL-6、 IL-8) 释放从而产生抗炎作用。 UCB公司近期已完成"盐酸左西 替利嗪对儿童过敏性咳嗽的临床安全性和有效性研究。
综上所述, 盐酸左西替利嗪除抗组胺作用外的抗炎作用, 对于感染后咳嗽、 哮喘等气道炎症相关疾病的治疗无疑具有潜在临床应用价值。
2) 复方抗炎作用
早在 1989年英国科学家 Choudry通过研究炎性介质、 缓激肽和组胺对咳嗽反 射敏感性的作用发现, 呼吸道炎症可使气道内 PGE2、 缓激肽等炎症介质的合成 和释放增加, 从而增加咳嗽反射的敏感性, 导致一些病人对正常环境如冷空气刺 激物, 亦可出现咳嗽反应, 并证明气道内存在 PGE2, 咳嗽反射即可增加, 因而抑 制前列腺素合成的药物, 可作为慢性咳嗽的新疗法。 因此, 研制对多种炎症介质 有协同抑制作用, 并通过多途径发挥抗炎效应的新药,无疑对慢性咳嗽等呼吸道 炎症相关疾病的治疗更为有效。
经检索, 印度灵药生物技术有限公司专利 "新颖的抗变态反应抗炎组合物" (ZL98122317.6)授权了一种新颖的尼美舒利及其盐与西替利嗪的组合物, 该组 合物具有抗白三烯、抗组胺、抗变态反应和抗炎作用, 可用于治疗变态反应性疾 病, 如鼻炎、 支气管炎、 哮喘等疾病。 该专利新组合物对多种炎症介质的协同抑 制作用而发挥抗炎作用, 从而达到治疗呼吸道炎症等疾病的目的, 与上述英国学 者的假想吻合。然而尼美舒利作为非 体抗炎药,近年来不良反应报道日益增多, 导致多个国家含有尼美舒利产品的退市, 限制了该新组合物的应用。
如前所述, 国内外均有布洛芬、盐酸左西替利嗪单一成分用于呼吸道炎症疾 病治疗的临床报道,但其疗效尚不能完全满足临床需求, 且未见两者组成复方制 剂的研究报道或产品上市。本发明通过试验证实,右布洛芬和左西替利嗪的联合 使用在抗炎方面表现出更为优异的协同作用,能够显著缓解气道炎症相关的炎性 肿胀、 血管通透性增加、 打喷嚏、 流涕、 鼻黏膜炎症等各种不适症状, 其作用机 制与显著抑制炎性因子表达有关。根据其作用机理,有望将其研发成新的气道炎 症治疗药物,给临床医生和患者在重症疾病使用激素治疗之前,提供了一个全新 的选择, 从而最大限度减少或避免毒副作用较大的激素使用和抗生素的滥用。 发明内容:
