In China, almost all children are administered vitamin A and D preparations daily and over the long term. Children are sensitive to elemental impurities, including heavy metals. However, there are no regulatory requirements or reports on the risk assessment of elemental impurities in marketed vitamin A and D preparations. Objective: The aim of this study was to propose an accurate and efficient method suitable for samples from different manufacturers to detect elemental impurities and conduct risk assessments according to the ICH Q3D guidelines. Methods: We developed a universally applicable digestion method for capsules and an ICP–MS method for quantitative analysis of 28 elemental impurities in vitamin A and D formulations. These methods were validated according to the USP 233 guidelines. Elemental impurities in 15 batches of vitamin A and D products from 10 manufacturers and their capsule shells were determined, and risk assessment was conducted according to the International Council for Harmonization Q3D guidelines. Results: All elemental impurities of toxicological concern met the Q3D requirements. However, the concentrations of various elements, including those of lead (not detected to 4.1 µg/g), arsenic (not detected to 7 µg/g), aluminum (not detected to 888 µg/g), and palladium (not detected to 36 µg/g), varied markedly. Moreover, the lead content in one batch from one manufacturer exceeded the control threshold. Conclusion: In this study, we successfully developed an effective digestion method for processing capsules containing samples from different sources and a sensitive ICP–MS method for quantitative determination of 28 elemental impurities in vitamin A and D preparations. ICP–MS should be implemented for the evaluation and control of elemental impurities in vitamin A and D preparations. This will ensure safe long-term vitamin A and D supplementation in children","PeriodicalId":10889,"journal":{"name":"Current Pharmaceutical Analysis","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142264823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fueled by using DNA's discovery in the 1950s, biotechnology has converted through genetic engineering, yielding impactful merchandise regulated by means of entities like the FDA. The manufacturing involves upstream and downstream processing including the various techniques involved in the downstream processing of biotechnological drugs, along with relevant guidelines and chromatographic analysis methods. The biotechnological industry, which integrates biological science with engineering, has significantly advanced since the discovery of DNA's structure, leading to the development of biopharmaceuticals. These drugs, including monoclonal antibodies, recombinant proteins, and gene therapies, are produced using living organisms and hold the potential for treating complex diseases. The downstream process, a crucial phase in biopharmaceutical production, involves the purification and formulation of drug products to meet stringent regulatory standards. Traditional techniques such as centrifugation, filtration, and chromatography are employed to extract and purify biopharmaceuticals. Chromatographic techniques, including ion exchange, affinity, and size exclusion chromatography, play a pivotal role in achieving the desired purity levels. However, these methods are often time-- consuming and expensive, necessitating continuous advancements in the field. The paper highlights the importance of regulatory guidelines, including cGMP, in ensuring the quality and safety of biopharmaceuticals. It also discusses the significant role of organizations such as the FDA and EMA in regulating biotechnological drug production. The evolution of downstream processing techniques and the development of novel methods promise greater efficiency, scalability, and cost-effectiveness in biopharmaceutical production. Understanding these advancements is essential for continued growth and innovation in the industry, ultimately contributing to improved patient care and pharmaceutical innovation.","PeriodicalId":10889,"journal":{"name":"Current Pharmaceutical Analysis","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142181868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the previous literature reports, the atypical peak may be caused by various factors such as post-translational modifications (PTMs), method-induced artifacts, sample degradation and sequence variants. Due to the high complexity structure of mAbs and the limitations of CE-SDS, acquiring comprehensive profiling of atypical peaks has historically been challenging. Objective: Here we developed a strategy utilizing complementary analytical methods to identify the cause of atypical peak. Methods: This strategy includes optimizing reduced CE-SDS method to evaluate artifacts induced by the analytical method, excluding potential glycation modifications, and utilizing Liquid Chromatograph Mass Spectrometer (LC-MS) to characterize mAb-X.

It is well-known for its capacity to hinder the development and division of cells, especially fast-dividing ones, like cancer cells, via the creation of DNA adduct. The currently published oxaliplatin analytical methods require a complex, difficult-to-understand procedure, and are costly. Objective: The main objectives of our study were to select the chromatographic parameters, develop a UFLC method and validate it, and validate the results according to ICH guidelines. Method: In this UFLC study, a normal phase C18 column (250cm x 4.6 mm x5 μm) with a mobile phase containing 0.01 M orthophosphoric acid and acetonitrile (95:5 V/V) has been used at pH 3.5. Flowrate has been fixed at 1ml/min and the sample has been tested in the UV range for detection. The methods have been validated for precision, linearity, forced degradation studies, robustness, and accuracy. Results: The retention time of the drug has been found to be >8min. The calibration curve of the drug has been obtained within the range of 10–240 μg/ml. The results of this analysis have been validated according to ICH guideline Q2 (R1) for registration of human use. Conclusion: The UFLC method we have used for oxaliplatin quantification has been found to be simpler, easier to understand, and more cost-effective than standard HPLC as it has consumed less mobile phase and less time.

Methods: In this research, spermidine and 10 other kinds of Biogenic amines in Radix astragali samples were identified and determined using High-Performance Liquid Chromatography-Diode Array Detector (HPLC-DAD) with precolumn derivatization.
