“…A amostra final foi composta por 12 artigos, todos estavam no idioma inglês. Quanto ao país de origem das pesquisas, observou-se predominância na amostra de estudos na China, com seis artigos (JIN et al, 2018;FANG et al, 2020;CHAN et al, 2021;REN et al, 2022;WANG, T. et al, 2022;WANG, Z. et al, 2022). Outros países presentes na amostra foram: Estados Unidos (GOLLAPALLI et al, 2019;ACHANTA et al, 2022) Alguns estudos citam, fora a fabricação inadequada, a indevida consideração aos medicamentos genéricos, como diazepam, risperidona e clozapina.…”

“…However, it can only control the total amount of polymerized impurities, with low column efficiency, poor resolution, and long separation time. Compared with GFC, the high‐performance size exclusion chromatography (HPSEC) method and the reversed‐phase, high‐performance liquid chromatography (RP‐HPLC) method have the advantages of high separation efficiency, high sensitivity, and short analysis time 9–12 …”

“…Compared with GFC, the highperformance size exclusion chromatography (HPSEC) method and the reversed-phase, high-performance liquid chromatography (RP-HPLC) method have the advantages of high separation efficiency, high sensitivity, and short analysis time. [9][10][11][12] The RP-HPLC method was used to determine related substances in drugs, and GFC/HPSEC method was used for quantitative analysis of the polymerized impurities in cefamandole nafate in the reported literature, [13][14][15][16][17][18] but the impurity profile and the structures of polymerized impurities were not studied systematically and characterized using HPLC-MS. 19 In this study, reverse phase high-performance liquid (Shanghai, China). Water was deionized and further purified using a Millipore Milli-Q-Gradient purification system (Millipore, Waters, Milford, MA, USA).…”

Rationale Reversed‐phase, high‐performance liquid chromatography (RP‐HPLC) and high‐performance size exclusion chromatography (HPSEC) methods were developed to effectively separate unknown impurities and polymerized impurities in cefamandole nafate. The liquid chromatography‐tandem ion trap/time‐of‐flight mass spectrometry (LC‐IT‐TOF‐MS) was applied to characterize the structures of the impurities. Ultraviolet (UV) spectrum characteristics and mass spectrum characteristics of △3‐isomer and 7‐epimer in cefamandole nafate were studied to distinguish the isomers. Methods RPLC‐IT‐TOF‐MS was used to characterize the structures of unknown impurities and polymerized impurities eluted from the C18 column. On this basis, the two‐dimensional (2D) HPSEC‐IT‐TOF‐MS was used to confirm the structures of polymerized impurities eluted from the TSK‐gel G2000SWxl column. Complete fragmentation patterns of impurities were studied and used to obtain information about the structures of the impurities. Results The structures of 19 unknown impurities in cefamandole nafate were elucidated based on the high‐resolution MSn data with both positive and negative modes, assisted by the UV spectra and stress testing, of which 2 impurities were polymerized impurities. Cefamandole nafate produced a series of degradation impurities, and another principal component cefamandole acid also produced a series of similar degradation impurities. The disciplines between mass fragmentation pattern/UV spectrum and structure for △3‐isomer and 7‐epimer were presented to distinguish their structures. Conclusions The results of this study provided a scientific basis for the improvement of official monographs in pharmacopoeias to effectively control the impurities and ensure drug safety for the public. This study also revealed the formation mechanisms of degradation impurities in cefamandole nafate, which may guide industry to improve the manufacturing process and storage conditions to reduce the content of impurities in products.

“…Furthermore, RP-HPLC-MS can also be used to analyze polymerized impurities. [20][21][22] For cloxacillin and flucloxacillin, various analytical techniques have been developed to estimate the quality of pharmaceuticals. [23][24][25][26] However, the impurity profile and the structures of many polymerized impurities in cloxacillin and flucloxacillin were not studied systematically and characterized using RP-HPLC-MS.…”

RationaleCloxacillin and flucloxacillin are prone to degradation and polymerization in humid and hot environments, and their polymers have long been recognized to trigger allergic manifestations. A series of the degradation and polymerized impurities in cloxacillin and flucloxacillin were separated and characterized to ensure safe use of these drugs by the public.MethodsBy studying the chromatographic behavior of the degradation impurities and polymerized impurities in reversed‐phase high‐performance liquid chromatography (RP‐HPLC) gradient elution, the impurities in cloxacillin and flucloxacillin were effectively separated and eluted. RP‐HPLC tandem ion trap/time‐of‐flight mass spectrometry (MS) was applied to characterize the structures of unknown impurities eluted from the RP‐HPLC methods for cloxacillin and flucloxacillin. The mechanisms of formation of the impurities in cloxacillin and flucloxacillin were also investigated.ResultsThe structures of 10 unknown impurities in cloxacillin and 8 unknown impurities in flucloxacillin were elucidated based on the high‐resolution MSn data at positive and negative modes, respectively. Six polymerized impurities were found and characterized, of which three were from the polymerization of cloxacillin and three were from the polymerization of flucloxacillin.ConclusionsThe study on the impurity profiles of cloxacillin and flucloxacillin provided a scientific basis for improving their production processes and quality control.
