Physicochemical Properties of Iodixanol
Acta Radiologica, 1995Iodixanol, the radiopaque in Visipaque, is a new nonionic, dimeric roentgen contrast medium for intravascualr use. Compared to aqueous solutions of nonionic monomers, which have higher osmolality than blood, aqueous solutions of iodixanol have a lower osmolality due to dimeric structure of the molecule.

Physicochemical properties of enrofloxacin
Journal of Pharmaceutical and Biomedical Analysis, 1997The physicochemical properties of enrofloxacin, a fluoroquinolone that inhibits the activity of bacterial DNA gyrase, are described. Its spectral, solubility and related physicochemical characteristics are discussed. The dissociation behaviour of enrofloxacin was examined by UV spectrophotometry at 25 degrees C in a series of buffers ranging from pH 1 ...

The physicochemical properties of digoxin
Journal of Pharmaceutical and Biomedical Analysis, 1985In a study of variations in the physicochemical properties of digoxin powder from several commercial sources, recrystallizations of digoxin were performed under several conditions. Polymorphs were not obtained whereas a pure amorphous form was formed under certain conditions.

On the Physicochemical Properties of Pyridohelicenes
Chemistry – A European Journal, 2013AbstractA comprehensive study on the physicochemical properties of a series of mono‐ and diaza[5]helicenes as well as mono‐ and diaza[6]helicenes is reported. Through the use of both computational and experimental methods, these helically chiral pyridohelicenes with the nitrogen atom(s) in various positions are characterised according to their ...

Physicochemical properties of bergenin
Die Pharmazie, 2008Physicochemical properties of bergenin, namely the solid state characteristics, solution stability, dissociation constant (pKa), solubility and octanol/water partition coefficient (Log P) were investigated. The results showed that the drug was not hygroscopic and was stable against heat and humidity in the solid state, but sensitive to hydrolysis in ...
