The reduction of bacterial endotoxin, known as depyrogenation, is crucial for preparing primary packaging components like ampoules for use in injectable drug products. The durability of glass ampoules depends on the proper annealing process. If glass is not annealed correctly, it is prone to cracking or shattering from even small changes in temperature or from mechanical shock or stress. To evaluate the effectiveness of sterilization and depyrogenation, a dry heat oven at 250°C was used for 30 minutes. The Limulus Amebocyte Lysate (LAL) assay was utilized to detect endotoxin, and efficient sterilization and depyrogenation were observed at this temperature. The impact of heating glass ampoules to various temperatures on the process of sterilization and depyrogenation was studied. This investigation covered a range of temperatures (250°C - 550°C), and included holding stage times (105, 120, and 200 seconds) corresponding to the belt speed. The removal of endotoxins was achieved by exposing to temperatures from 350°C to 550°C for specific time intervals and at 300°C with an exposure time of 200 seconds. The absence of endotoxin was observed when annealing glass ampoules at 500°C for 105 seconds, regardless of the ampoules' size. Alternative methods for testing depyrogenation of sealed ampoules, such as ethylene oxide (EtO), sodium hydroxide (NaOH), and hydrochloric acid (HCl), were also demonstrated to have a clear comparison against temperature which considered the best effective economic method . This research indicates that annealing sealed glass ampoules at specific temperatures can serve as a replacement for sterilization and depyrogenation processes prior to filling, leading to savings in time, labor, machine work, energy, and cost.</p>","PeriodicalId":16741,"journal":{"name":"Journal of pharmaceutical sciences","volume":" ","pages":"103769"},"PeriodicalIF":3.7,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143692551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the importance of such extractable screening studies in assuring product quality and patient safety, it has become apparent that inconsistencies in their execution between laboratories have resulted in the potential for differences in the qualitative and/or quantitative aspects of the extractable profiles obtained. Since this issue was discovered primarily through anecdotal accounts, a working group within ELSIE conducted two industry surveys that inquired into impactful variables of extractable screening study design and execution. After completion of these surveys, it was concluded that there were numerous variables where labs were not well aligned, which may be impacting the consistency of the data generated to some extent.

The fraction of unbound lofexidine in the breast milk was determined by a Rapid Equilibrium Dialysis (RED) assay.
