Solubility of selected derivatives of 1,4-benzodiazepine-2-one in the presence of PVP.
نویسنده
چکیده
Pharmaceutical availability of diazepam, oxazepam and nitrazepam from solid dispersions of PVP have been studied in comparison to those of the corresponding physical mixtures and pure benzodiazepines. The derivatives of 1,4-benzodiazepin-2-one are poorly water soluble drugs. The properties of diazepam-, oxazepam- and nitrazepam-PVP solid dispersions have been determined by the methods of differential scanning calorimetry (DSC) and X-ray diffraction. The effect of PVP on the solubility of selected derivatives of 1,4-benzodiazepin-2-one has been studied. The solubility of diazepam, oxazepam and nitrazepam from its solid dispersion has been found to increase in presence of PVP.

In this study, oxidation of some 3,5-diacyl or 3,5-diester 1,4-dihydropyridines to corresponding pyridine derivatives using sodium bromate in the presence of NH4Cl, NaHSO4 and Bu4NHSO4 under thermal conditions has been investigated. The yield and structure of formed products is similar under all conditions; however, the reaction is accelerated in the presence of Bu4NHSO4 and NaHSO4. In addition...

This study presents the influence of hydroxypropyl-β-cyclodextrin (HPBCD) on the aqueous solubility of acyl esters of cyproterone. First, a number of esters of cyproterone were synthesized. Then the phase solubility analysis of the compounds in the presence of HPBCD was investigated in phosphate buffer solution at a pH of 7.4. To gain a better understanding of the complexation mechanism, ...
