概括
无防腐剂的多剂量眼滴可以防止瓶子的污染,但与防腐剂选项相比,在盖子和初始滴滴上显示出更高的微生物生长. 这突显了瓶子无菌性和外部污染风险之间的权衡.
科学领域:
- 眼科医生 眼科 眼科
- 微生物学 微生物学
- 制药技术 制药技术 制药技术
背景情况:
- 多剂量眼滴需要有效的策略来防止微生物污染.
- 无防腐剂配方提供了传统防腐眼滴的替代品,可能减少眼睛表面的毒性.
- 评估无防腐剂多剂量眼滴技术的微生物安全性对于患者护理至关重要.
研究的目的:
- 为了评估无防腐剂多剂量 (PF-MDB) 眼滴技术的污染预防有效性.
- 为了比较PF-MDB和保存多剂量布里莫尼丁 (P-MDB) 眼滴之间的微生物污染水平.
主要方法:
- 这是一项前性研究,涉及54名使用PF-MDB和P-MDB眼液的青光眼患者.
- 分析眼滴剂上的帽子,第一滴和第二滴在巧克力和绵羊血上.
- 使用无菌技术检查微生物污染.
主要成果:
- 在PF-MDB或P-MDB的瓶子里没有检测到微生物生长.
- 与P-MDB相比,在PF-MDB的上限和初始滴滴上观察到明显更高的污染水平.
- 污染从PF-MDB的第一次下降增加到第二次下降,这表明后续使用的风险更高.
结论:
- 无防腐剂的多剂量瓶技术成功防止了内部微生物污染.
- 由于PF-MDB中没有防腐剂,导致外部组件 (如盖子和初始滴) 上的细菌和真菌生长增加.
- 必须考虑无防腐剂配方的好处与外部微生物污染的风险增加之间的平衡.

168
Generic intravenous (IV) drugs are considered bioequivalent to their branded counterparts due to their 100% bioavailability upon administration. However, variations in stability among different drug products can significantly influence their therapeutic performance, even if they are pharmaceutically equivalent.Cefuroxime, a prophylactic antimicrobial, is often used as a single-dose IV injection for patients undergoing coronary artery bypass grafting surgery. A 3 g dose typically provides...

Pharmaceutical products contain more than just the active drug; they also contain various excipients such as binders, solubilizers, stabilizers, preservatives, and other elements. In some cases, impurities or contaminants might be present. Traditionally, quality control in pharmaceuticals has primarily focused on the analysis of the active drug, often overlooking the impact of these additional components. The recent issue with heparin contamination by over-sulfated chondroitin sulfate, a...
