usp美国药典等级
usp美国药典等级美国药典级usp calss vi美国药典级(usp)实际上含义:美国药典(usp)是一个非政府组织,通过建立最新的标准来保证药品和其他保健技术的质量,从而支持公共卫生。
该组织与制药和生物技术行业有关。
美国药典规定了质量、纯度、强度和一致性的标准。
这些usp 标准发表在《美国药典》和《国家处方集》(usp nf)中。
usp第四类产品经过一系列的生物试验。
usp第六类化合物必须由具有明确生物相容性历史的成分制成,以满足对渗滤液的严格要求。
动物用来测试材料的毒性。
急性毒性试验:该试验测量试验材料的刺激性,控制其对人体的潜在危害。
毒性由口腔、皮肤和吸入决定。
皮内试验:这种特殊的试验将材料直接注射到正常使用过程中接触到的组织中,不保护皮肤或任何其他身体系统。
这将允许测试团队评估特定组织对材料的响应。
植入试验:植入试验确定植入活体动物时活体组织对材料的反应。
usp六级试验所需的标准植入时间为5天。
如果在5天后没有刺激或毒性的迹象,它将满足试验的植入要求。
温度和时间:用于全身毒性和皮内试验的材料提取物固定在设定的温度和暴露时间,以确保结果符合通用标准。
用三种不同的温度和时间暴露条件处理所有的材料提取物。
前72小时在122°F或50°C下给药,然后在158°F下给药24小时,最后在250°F下给药1小时。
usp第六类塑料试验旨在评价各种塑料材料在体内的生物反应性。
为了测试药物容器,塑料类测试经常在未焊接的塑料树脂和容器上进行。
类塑料测试不是生物相容性测试的替代品,但通常被制造商用来对材料进行分类。
塑料的分类包括三种体内试验。
系统注射试验和皮内试验旨在通过单剂量注射特定提取物来控制对塑料和其他聚合物的全身和局部生物反应。
第三种测试,即植入测试,旨在评估活组织对测试材料的反应。
利用这三个试验和不同提取物的不同排列,完成了六个不同等级的塑料等级试验。
usp定义了六种塑料类别,从i到vi(vi仍然是最严格的)。

三、内容解析 除开文字上的差异外,美国药典的格式与中国药内几乎一致。最主 要的区别还是内容上的不同。大致有以下几点: 1、美国药典将配成的溶液分为可储存的溶液和一般供试品溶液, 因为其在研究的基础上提供了该方法,使得溶液配制有依据,该方 法的提供使得操作人员在执行此项操作时有了更大的把握,而不是 抱着侥幸心理去处理样品。 2、美国药典大部分药品在色谱分析上使用了两种以上的分析方法, 而不是一种方法既用在含量项下,又用在相关物质限度上。比如氯 吡格雷,含量项下用的是普通反相柱,而相关物质上用的是正相柱, 使得分析更为准确可靠。 3、美国药典在相关物质上的规定与中国药典不尽相同,中国药典 大部分品种将所有杂质合为一个总杂质含量,而未对单一杂质作出 要求。而美国药典在详尽的毒理研究基础之上,对各种大于0.1% 的杂质作出了要求,这样使药品的运用更为安全可靠。

一、美国药典概况 美国药典是美国政府对药品质量标准和检定 方法作出的技术规定,也是药品生产、使用 、管理、检验的法律依据。 美国药典于1820年出第一版,每年更新, 至今已出至第38版。 其格式分为USP 通则, USP 各论 A-Z, 完 整索引,完整目录表。下面以原料药硫酸氢 氯吡格雷为例子,讲解美国药典38版的格 式。

三、内容解析 除开文字上的差异外,美国药典的格式与中国药内几乎一致。最主 要的区别还是内容上的不同。大致有以下几点: 1、美国药典将配成的溶液分为可储存的溶液和一般供试品溶液, 因为其在研究的基础上提供了该方法,使得溶液配制有依据,该方 法的提供使得操作人员在执行此项操作时有了更大的把握,而不是 抱着侥幸心理去处理样品。 2、美国药典大部分药品在色谱分析上使用了两种以上的分析方法, 而不是一种方法既用在含量项下,又用在相关物质限度上。比如氯 吡格雷,含量项下用的是普通反相柱,而相关物质上用的是正相柱, 使得分析更为准确可靠。 3、美国药典在相关物质上的规定与中国药典不尽相同,中国药典 大部分品种将所有杂质合为一个总杂质含量,而未对单一杂质作出 要求。而美国药典在详尽的毒理研究基础之上,对各种大于0.1% 的杂质作出了要求,这样使药品的运用更为安全可靠。
