目的 探索建立通過仿制藥一致性評價品種上市后藥品質量一致性快速評判方法，用于市場仿制藥質量快速評價。方法 基于拉曼光譜法，根據質量控制需求，分別采用一致性評價參比制劑、申報批、同批次制劑作為參比標準，以相似度值、置信區(qū)間、不確定度作為評判指標。檢驗流程分為建庫和快檢 2 部分，建庫：參比制劑和申報批的拉曼光譜作為標準譜圖存于云端數據庫，或取市售仿制藥某批樣品自身某片藥品建庫；快檢：采集 10 片藥物制劑樣品拉曼光譜分別上傳，與拉曼光譜庫“四同”（同生產企業(yè)、同品種、同規(guī)格、同批號）樣品標準譜圖比對，在標準拉曼光譜庫中未能獲取標準譜圖時，進行市售批自身片與片之間比對?；谥袊庾V云計算中心“藥品追溯”模塊，優(yōu)化升級成“仿制藥評價”模塊，與仿制藥評價專用手持式拉曼光譜儀聯合，形成“仿制藥質量拉曼光譜快速評價系統(tǒng)（CEVAR 系統(tǒng)）”。該項目在2020 年度山東省藥品質量風險監(jiān)測項目中進行了應用，共征集到省內 18 家企業(yè)、45 個品種（73 個品規(guī)）、225 批次的市售批樣品；征集到 3 家企業(yè)、3 個品種、5 個批次的參比制劑；3 家企業(yè)、4 個品種、12 個批次的申報批樣品。取瑞舒伐他汀鈣片參比試劑和市售批用拉曼光譜成像系統(tǒng)進行驗證。結果 將相似度 99% 作為通用判定閾值；征集到的絕大多數品種的自身相似度都大于 99%，但是有 5 個品種樣品雖然平均相似度值大于 99%，但是每批次有 3～5 片與標準比對相似度小于 99%；充分證實CEVAR 系統(tǒng)檢測的準確性。瑞舒伐他汀鈣片拉曼光譜成像系統(tǒng)的驗證結果與 CEVAR 系統(tǒng)結果一致。結論 通過大批量樣品測試數據，相似度 99% 可以作為質量優(yōu)劣判定的閾值，CEVAR 系統(tǒng)適合于對藥物制劑工藝質量的普遍篩查。

Objective To establish a rapid evaluation method of drug that passed the consistency evaluation of generic drugs, which can be used to quickly evaluate the quality of the generic drugs in the market. Method Based on Raman spectroscopy, according to the quality control needs, the reference preparations, the submitted batch, and the batches of the same batch of the drug were used as reference standards respectively, and the similarity index, the confidence interval, and the uncertainty were used as evaluation indicators. The inspection process is divided into two parts: building a database and fast inspection. The building of the database: The Raman spectra of the reference preparations and the submitted batch are stored as standard spectra in the cloud database or built by taking a certain batch of a commercial imitation drug. The fast inspection: The Raman spectra of 10 drug preparations are collected and uploaded separately, and compared with the standard Raman spectra of the "four same" (same manufacturer, same variety, same specifications, and same batch number) samples in the Raman spectral database. When the standard Raman spectra of the database cannot be obtained, the comparison is made between the same batch of the commercial imitation drug and the same batch of the drug. Based on the China Raman Spectrum Cloud Computing Center's "Drug Traceability" module, the "Imitation Drug Evaluation" module is optimized and upgraded, combined with the imitation drug evaluation dedicated handheld Raman spectrometer, forming the "Imitation Drug Quality Raman Spectrum Rapid Evaluation System (CEVAR system)". This project was applied in the 2020 annual drug quality risk monitoring project in Shandong Province, a total of 18 enterprises from the province, 45 varieties (73 specifications), and 225 batches of commercial batch samples were collected; 3 enterprises, 3 varieties, and 5 batches of reference preparations were collected. Three enterprises, four varieties, and twelve batches of application batch samples were collected. The reference reagent and the in-market batch-use Raman spectrometry imaging system were used for validation. Result A general threshold of similarity of 99% was used as the criterion; the majority of the varieties collected had a self-similarity of greater than 99%, but five varieties had an average similarity value greater than 99%, but 3-5 pieces per batch had a similarity value with the standard less than 99%. This strongly confirms the accuracy of the CEVAR system. The validation results of the Raman spectrometry imaging system for Rosuvastatin calcium tablets were consistent with those of the CEVAR system. Conclusion According to data of mass sample testing, the similarity of 99% can be used as the threshold value for the determination of quality, and this method is suitable for the general screening of process quality of pharmaceutical preparations
