脾氨肽口服冻干粉装量差异检测数据
收藏资源简介:
装量差异,是药物制剂的均匀性检测指标之一。装量差异过大直接影响患者服用量的准确和药品的治疗效果。 检验人员严格按照检验操作规程进行检验和完成相关的记录,为本企业及同行业企业的装量差异检测提供依据。1、取10个最小单位的药品,逐个称量净含量,得到净含量1、净含量2......净含量10,然后计算得到净含量平均值; 2、再用以下公式计算得到10个差异百分比,差异百分比1=(净含量1-净含量平均值)/净含量平均值,差异百分比2=(净含量2-净含量平均值)/净含量......差异百分比10=(净含量10-净含量平均值)/净含量平均值; 3、根据中国药典规定,装量差异限度≤±10%,其中超出装量差异限度的供试品不得多于2瓶,并不得有1瓶超出装量差异限度的1倍。以此来判定是否合格。
Content variation is one of the uniformity testing indicators for pharmaceutical preparations. Excessive content variation directly undermines the accuracy of the dosage administered to patients and the therapeutic efficacy of the medicinal product. Inspectors shall conduct tests and complete relevant records strictly in accordance with standard test operating procedures (SOPs), providing a reliable basis for content variation detection for both this enterprise and other enterprises in the same industry. 1. Take 10 smallest dosage units of the medicinal product, weigh their net contents individually to obtain net content 1, net content 2… net content 10, then calculate the average net content; 2. Calculate 10 variation percentages using the following formula: Variation Percentage 1 = (Net Content 1 - Average Net Content) / Average Net Content, Variation Percentage 2 = (Net Content 2 - Average Net Content) / Net Content… Variation Percentage 10 = (Net Content 10 - Average Net Content) / Average Net Content; 3. Per the provisions of the Chinese Pharmacopoeia, the allowable content variation limit is ≤ ±10%. The number of test samples exceeding the allowable content variation limit shall not exceed 2, and no single test sample shall exceed 1 times the allowable limit. The qualification of the batch is determined according to these criteria.
