Acta pharmaceutica (Zagreb, Croatia)
Dec 1, 2018
The study describes the development and preliminary validation of a simple reverse-phase chromatographic method for determination of a novel drug candidate, 5-[(4-chlorophenoxy) methyl]-1,3,4-oxadiazole-2-thiol (OXCPM), in bulk and stressed solution,...
Stability of 90 mg/mL cefuroxime sodium solution for administration by continuous infusion.
Journal of chemotherapy (Florence, Italy)
Jan 1, 2018
Continuous infusions of β-lactam antibiotics increase pharmacokinetic/pharmacodynamic target attainment. However, this way of administration brings about some practical issues such as stability. This study aims to determine the stability of a 90 mg/m...
[Determination of total phthalates in perfume and their exposure assessment].
Se pu = Chinese journal of chromatography
Dec 8, 2017
A novel method for rapid screening of phthalates (PAEs) in perfumes was developed. The PAEs were hydrolyzed to phthalic acid (PA), and the PA in the acidified solution was extracted with tributyl phosphate (TBP) which was detected by high performance...
