简介:目的:研究八味痛风康微丸的抗痛风作用。方法:采用尿酸盐结晶(MSU)致大鼠急性痛风性关节炎模型及次黄嘌呤所致的小鼠高尿酸血症模型,观察八味痛风康微丸的抗痛风作用,并通过热板法、醋酸扭体法和甲醛法观察该药的镇痛作用;利用二甲苯致小鼠耳廓肿胀模型、角叉菜胶致大鼠足肿胀模型、小鼠毛细血管通透性模型,观察该药的抗炎作用。结果:八味痛风康微丸16.4g/kg以上剂量可明显抑制尿酸盐结晶(MSU)诱导的大鼠足跖肿胀,降低血清IL-1β和TNF-α水平,并能降低次黄嘌呤所致高尿酸血症小鼠的血尿酸水平;能提高小鼠的痛阈值,减少醋酸所致小鼠的扭体次数,并能够降低甲醛致小鼠镇痛实验中足中PGE2含量;八味痛风康微丸也可抑制醋酸所致小鼠毛细血管通透性的增加,抑制角叉菜胶大鼠足趾肿胀和二甲苯致小鼠耳廓肿胀。结论:八味痛风康微丸具有抗痛风、镇痛、抗炎作用,其作用机制可能与降低炎症因子IL-1β、、TNF-α和PGE2水平有关。
简介: 【摘要】 目的:探讨并分析多巴丝肼片(美多巴)联合盐酸普拉克索速释片治疗帕金森的临床效果及安全性。方法:此次研究的对象是选取笔者所在医院 2015年 5月 -2016年 7月收治的 78例帕金森病患者,将其临床资料进行回顾性分析,并采用随机数字法将其均分为对照组和观察组,每组 39例。对照组患者采用美多巴治疗,观察组患者采用美多巴联合盐酸普拉克索速释片治疗,比较两组患者治疗后的临床效果及不良反应发生率。结果:观察组的治疗总有效率 87%,明显高于对照组的 62%,差异有统计学意义(字 2=6.72, P<0.05);观察组的不良反应发生率 5%,明显低于对照组的 23%,差异有统计学意义(字 2=5.19, P<0.05)。结论:美多巴联合盐酸普拉克索速释片治疗帕金森病的临床效果显著,是值得在临床上推广使用的安全可靠的治疗方法。 【关键词】 帕金森病; 多巴丝肼片; 盐酸普拉克索速释片; 临床疗效; 安全性 Objective: To explore and analyze the clinical efficacy and safety of the treatment of Parkinson with the combination of the tablets and the fast release tablets of pramipexole hydrochloride. Methods: the object of this study was to select 78 cases of Parkinson's disease in the hospital of my hospital in July -2016 May 2015. The clinical data of the patients were analyzed retrospectively, and they were divided into the control group and the observation group by random number method, with 39 cases in each group. The patients in the control group were treated with methada, and the patients in the observation group were treated with the combination of methyopa and pramc. The clinical effect and the incidence of adverse reactions were compared between the two groups. Results: the total effective rate of treatment in the observation group was 87%, which was significantly higher than that of the control group (62%). The difference was statistically significant (word 2=6.72, P<0.05); the incidence of adverse reactions in the observation group was 5%, which was significantly lower than that of the control group (23%). The difference was statistically significant (word 2=5.19, P<0.05). Conclusion: the clinical effect of the combined treatment of dopa and pramopexo in the treatment of Parkinson's disease is significant. It is a safe and reliable method to be used in clinical practice.
简介:目的本文选择EudragitL100和EudragitRL30D分别作为微丸的肠溶和缓释包衣材料,将星点设计-效应面法应用于处方筛选过程中,制备卡马西平肠溶缓释微丸。方法采用综合评分法,以6h和12h两点的累积释放量作为评价指标,将包衣时间(间接代表包衣厚度)和增塑剂的比例作为自变量,采用星点设计-效应面法对肠溶缓释微丸处方进行优化。结果从星点设计-效应面法优化处方的三维响应面图可以看出,评分最优自变量处方为椭圆形的区域,在此区域内任取3点进行验证实验,通过对比评分标准,3批自制样品符合理论释药目标。结论星点设计-效应面优化法可用于卡马西平肠溶缓释微丸的包衣处方优化,所建模型具有较好地预测能力和实用性。
简介:摘要目的制备埃索美拉唑镁肠溶微丸,建立质量控制方案。方法应用流化床包衣法(底喷),成功制备出埃索美拉唑镁肠溶微丸,进行溶出度、耐酸力测定,评价埃索美拉唑镁肠溶微丸的质量。结果pH值6.8的人工肠液中,自制埃索美拉唑镁肠溶微丸的溶出度>86%,pH值1.2的氯化氢溶液中(模拟胃液环境),自制埃索美拉唑镁肠溶微丸的累积溶出度<2%。结论人工肠液中,自制埃索美拉唑镁肠溶微丸的溶出较完全,人工胃液中,自制埃索美拉唑镁肠溶微丸的耐酸力较好,该制备工艺可靠,药物质量理想,可推广。
