概括
这项研究表明,当作为连续的内灌时,万科米辛,达普托米辛和托布拉米辛在12小时内化学稳定. 尼卡迪也保持稳定8小时,支持其与IRRAflow设备的使用.
科学领域:
- 药理学 药理学是指药理学的学科.
- 神经科学是一个神经科学.
- 药物输送系统 药物输送系统
背景情况:
- 通过腹腔排水,如IRRAflow (IRRAS) 装置,通过连续的脑内灌是一种新兴的药物输送方法.
- 通常使用的药物包括万科米,托布拉米,达普托米和尼卡迪平.
研究的目的:
- 为了评估低度的达普素,尼卡尔迪平,托布拉素和万科素的化学稳定性,这些药物是通过IRRAflow导管注射的.
- 为了确定这些药物在特定条件下保持完整性的持续时间.
主要方法:
- 商业上可用的万科米辛,达普米辛,托布拉米辛和尼卡迪平被稀释在正常盐水中 (NS) 以达到目标度.
- 用超高性能液体染色学和双重质谱法 (LC-MS/MS) 在不同时间点 (0,6,12小时用于万科米辛,达普托米辛,托布拉米辛;0,4,8小时用于尼卡迪平) 分析样品.
- 所有样品都储存在室温下,并暴露在环境光线下.
主要成果:
- 12小时后,万科米辛,达普米辛和托布拉米辛的初始度保持在90%以上.

In Vitro Drug Dissolution: Alternative Methods
Alternative drug dissolution methods include the rotating bottle, intrinsic dissolution test, peristalsis, and the Franz diffusion cell method. The rotating bottle method involves meticulously rotating tightly capped controlled-release beads in a temperature-controlled bath. Periodic decanting of samples allows for residue assay, followed by refilling with fresh medium and testing at various pH levels to emulate the gastrointestinal tract conditions.In contrast, the intrinsic dissolution test...
Pharmaceutical Alternatives: Stability-Related Therapeutic Nonequivalence
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...
