一種福多司坦吸入用溶液製劑及其製備方法和用途A solution preparation for inhalation of fudosteine and its preparation method and application

本發明關於藥物製劑領域,具體關於一種福多司坦吸入用溶液製劑及其製備方法和用途。The invention relates to the field of pharmaceutical preparations, in particular to a fudosteine inhalation solution preparation and its preparation method and application.

呼吸系統疾病是人們所熟悉的病種之一,呼吸系統疾病約占內科病人的1/4,給病人帶來精神和肉體上的痛苦,在我國人口統計中,呼吸系統疾病為第二位死因,但臨床上可供選擇的藥物並不多,且起效較慢。Respiratory system disease is one of the diseases that people are familiar with. Respiratory system disease accounts for about 1/4 of internal medicine patients and brings mental and physical pain to patients. In my country's population statistics, respiratory system disease is the second cause of death , but there are not many drugs to choose from clinically, and the onset is slow.

咳痰為呼吸系統疾病的常見症狀,痰液的增加可刺激呼吸道黏膜引起咳嗽。當痰液阻塞細支氣管時,不僅可引起氣喘,還能引起繼發感染,進一步損傷呼吸道,加重咳嗽、咳痰和氣喘,嚴重者可抑制呼吸或窒息致死。黏液的過度分泌會引起黏液纖毛清除功能障礙和局部防禦功能損害,導致感染難以控制和氣道阻塞加重,直接影響病情進展和患者主觀感受,故使用祛痰藥物促進氣道內分泌物的儘快外排是治療氣道炎症的重要輔助措施。Coughing up sputum is a common symptom of respiratory diseases. Increased sputum can stimulate the respiratory mucosa and cause coughing. When sputum blocks the bronchioles, it can not only cause asthma, but also cause secondary infection, further damage the respiratory tract, aggravate cough, expectoration and asthma, and in severe cases, it can inhibit breathing or suffocate to death. Excessive secretion of mucus will cause mucociliary clearance dysfunction and local defense function damage, leading to difficult control of infection and aggravation of airway obstruction, which directly affects the progress of the disease and the patient's subjective feelings. Important adjunct to airway inflammation.

祛痰藥能使痰液變稀、黏稠度降低而易於咳出,或者能加速呼吸道黏膜纖毛運動,改善痰液轉運功能藥物。祛痰藥能促進呼吸道管腔內積痰的排出,減少對呼吸道黏膜的刺激,間接起到鎮咳和平喘的作用,也有利於控制繼發感染。Expectorants can make sputum thinner and less viscous, making it easier to cough up, or can accelerate the movement of mucous membranes and cilia in the respiratory tract and improve sputum transport function. Expectorants can promote the discharge of phlegm in the respiratory lumen, reduce irritation to the respiratory mucosa, indirectly play an antitussive and antiasthmatic role, and are also beneficial to control secondary infections.

福多司坦,化學名為(-)-(R)-2-氨基-3-(3-羥丙基硫代)丙酸,是一種新型的祛痰藥,由日本三菱製藥株式會社和S.S製藥株式會社研製具有司坦(steine)基本骨架的一類具有祛痰作用的半胱氨酸衍生物。其對慢性呼吸系統疾病有多重藥理作用:抑制呼吸道上皮細胞增生,使痰中海藻糖/唾液酸的比值正常化,恢復纖毛輸送氣道分泌液的狀態,並有抗炎作用;具有藥效強,副作用小,適應症廣,市場潛力大等優點;適用於支氣管哮喘、慢性支氣管炎、支氣管擴張症、肺結核、塵肺症、肺氣腫、非典型分枝桿菌感染、彌漫性細支氣管炎等慢性呼吸系統疾病的祛痰。Fudosteine, whose chemical name is (-)-(R)-2-amino-3-(3-hydroxypropylthio)propionic acid, is a new type of expectorant, manufactured by Mitsubishi Pharmaceutical Co., Ltd. and S.S.

The control group inhaled physiological saline, and the treatment group was orally or inhaled the corresponding dose of fudosteine (fudosteine solution obtained in Example 6). After 30 minutes of administration, 1% phenol red saline solution was injected intraperitoneally, and euthanized mice were euthanized by excessive inhalation of CO 2 after 30 minutes. The syringe was inserted into the trachea and slowly injected, and then slowly sucked out. This was repeated 3 times. The combined lavage fluid was placed for a certain period of time to allow impurities to precipitate, and a transparent red supernatant was obtained. The color was measured at a wavelength of 545 nm, according to phenol red The amount of phenol red was calculated from the standard curve. The experimental results are shown in Table 10: Table 10.

在小鼠酚紅排泄試驗中,吸入給予福多司坦20-60 mg/kg,可使小鼠酚紅排泄量增加,增加的水平隨吸入劑量的增高而增多。其中,吸入給予60mg/kg、40 mg/kg福多司坦,能夠使小鼠酚紅排泄量顯著增加。表明霧化吸入福多司坦可通過促進氣道漿性液的分泌而稀釋痰液,起到祛痰作用,且該作用呈現劑量依賴性。與口服給藥(P.O) 60 mg/kg相比,吸入給予福多司坦20-60 mg/kg藥效更優,在相同劑量下吸入給予福多司坦祛痰作用顯著優於口服。 實驗例12、福多司坦霧化吸入重複給藥毒性試驗 In the phenol red excretion test in mice, inhalation administration of fudosteine 20-60 mg/kg can increase the excretion of phenol red in mice, and the level of increase increases with the increase of inhalation dose. Among them, inhalation administration of 60 mg/kg and 40 mg/kg fudosteine can significantly increase the excretion of phenol red in mice. It shows that aerosol inhalation of fudosteine can dilute sputum by promoting the secretion of airway serous fluid and play an expectorant effect, and this effect is dose-dependent. Compared with oral administration (P.O) 60 mg/kg, inhalation administration of fudosteine 20-60 mg/kg has better efficacy, and at the same dose, inhalation administration of fudosteine has significantly better expectorant effect than oral administration.

SD大鼠每天1次,連續4周吸入給予生理鹽水或福多司坦(採用實施例2的福多司坦溶液,充分暴露至最大可行劑量,分別為:39.34 mg/kg、236.03 mg/kg)。實驗過程中各劑量組均正常存活到實驗結束,動物體重、耗食量、詳細的臨床均未見異常,臨床病理指標(包括血液學、血清生化、凝血和尿液分析)均未見與供試品相關的毒理學變化,動物大體解剖、臟器重量以及病理檢查均未見與供試品相關異常。毒代動力學實驗中福多司坦吸入用溶液製劑的暴露量隨給藥劑量的增加而升高。在本試驗條件下福多司坦吸入用溶液製劑在SD大鼠中未觀察到損傷作用的劑量水平(NOAEL)為236.03 mg/kg。表明福多司坦溶液吸入給藥安全性良好。SD rats were inhaled once a day with normal saline or fudosteine (using the fudosteine solution in Example 2, fully exposed to the maximum feasible dose, respectively: 39.34 mg/kg, 236.03 mg/kg ). During the experiment, all dose groups survived normally until the end of the experiment, and no abnormalities were found in animal weight, food consumption, and detailed clinical conditions, and no clinical and pathological indicators (including hematology, serum biochemistry, coagulation, and urinalysis) were found to be consistent with those for the test. Toxicological changes related to the test product, animal gross anatomy, organ weight and pathological examination showed no abnormalities related to the test product. In the toxicokinetic experiment, the exposure of fudosteine solution for inhalation increased with the increase of the administered dose. Under the conditions of this test, the no-observed-effect dose level (NOAEL) of fudosteine solution for inhalation in SD rats was 236.03 mg/kg. It shows that fudosteine solution is safe for inhalation administration.

結論:採用本發明製備的福多司坦溶液用於霧化吸入給藥,與口服相比能夠增加呼吸系統的暴露量,相同劑量在氣管的暴露量提高近6倍,在肺組織提高近1倍。福多司坦藥效機制全面,在增加酚紅排泄的藥效實驗中,與口服給藥相比,吸入四分之一至相等的劑量能夠達到相當或更優的作用,當吸入劑量為口服劑量的六分之一時藥效作用不佳。毒性試驗表明霧化吸入福多司坦安全性良好。福多司坦口服製劑臨床用法用量為成人每次400mg,每天3次。基於實施例1-6製備的福多司坦溶液,結合實驗例10-12的研究結果,推測福多司坦每次霧化吸入100-400mg,與口服用藥相比能達到相當或更優的藥效並且安全性良好。在此基礎上開展進一步的藥學研究,結合臨床霧化吸入用藥規範的要求,探索出最優的福多司坦霧化吸入製劑,以期在臨床使用中達到最優的綜合獲益。 實驗例13、處方變量的風險評估 Conclusion: The fudosteine solution prepared by the present invention is used for aerosol inhalation administration, which can increase the exposure of the respiratory system compared with oral administration. The exposure of the same dose in the trachea is increased by nearly 6 times, and the exposure in the lung tissue is increased by nearly 1 times. The pharmacodynamic mechanism of fudosteine is comprehensive. In the pharmacodynamic experiment of increasing the excretion of phenol red, compared with oral administration, inhalation of a quarter to an equal dose can achieve equivalent or better effects. When the inhalation dose is oral administration The drug effect is not good at one-sixth of the dose. Toxicity tests showed that aerosol inhalation of fudosteine was safe. The clinical dosage of fudosteine oral preparations is 400 mg each time for adults, 3 times a day. Based on the fudosteine solution prepared in Examples 1-6, combined with the research results of Experimental Examples 10-12, it is speculated that fudosteine can be inhaled at 100-400mg by nebulization each time, which can achieve equivalent or better efficacy compared with oral administration. The efficacy and safety are good. On this basis, further pharmaceutical research will be carried out, combined with the requirements of clinical nebulization inhalation medication specifications, to explore the optimal fudosteine nebulization inhalation formulation, in order to achieve the best comprehensive benefit in clinical use.

由上述結果可知,本品濃度為25mg/ml~250mg/ml可滿足遞送總量100~400mg,可實現對應藥效。但濃度越大,霧化杯會有晶體析出,晶體析出過多可導致本品有效利用率較低,因此優選福多司坦吸入用溶液製劑濃度<250mg/ml。From the above results, it can be seen that the concentration of this product is 25mg/ml~250mg/ml, which can meet the delivery of a total amount of 100~400mg, and can achieve the corresponding drug effect. However, the higher the concentration, the crystals will be precipitated in the atomization cup, and too much crystals will lead to a lower effective utilization rate of this product. Therefore, the concentration of fudosteine solution for inhalation is preferably less than 250 mg/ml.

根據福多司坦吸入用溶液臨床霧化吸入藥物治療時,霧化時間不宜超過30min為宜。由以上結果可知,福多司坦吸入用溶液製劑濃度應≥30mg/ml。According to fudosteine inhalation solution clinical nebulization inhalation drug treatment, the nebulization time should not exceed 30min. From the above results, it can be known that the concentration of fudosteine solution for inhalation should be ≥30mg/ml.
