Application of experimental design in the examination of the dissolution rate of carbamazepine from formulations. Characterization of the optimal formulation by DSC, TGA, FT-IR and PXRD analysis
(Srpsko hemijsko društvo, Beograd, 2015)
Poor solubility is one of the key reasons for the poor bioavailability of carbamazepine drugs. This study considers formulation of solid surfactant systems with carbamazepine, in order to increase its dissolution rate. ...
Development and validation of a solid phase extraction-HPLC method for the determination of carbamazepine and its metabolites, carbamazepine epoxide and carbamazepine trans-diol, in plasma / Razvoj i validacija spe-HPLC metode za određivanje karbamazepina i metabolita karbamazepin epoksida i karbamazepin trans-diola u plazmi
(Srpsko hemijsko društvo, Beograd, 2012)
A solid phase extraction-HPLC method has been developed and validated for the rapid analysis of carbamazepine and its two metabolites, carbamazepine epoxide and carbamazepine trans-diol, in human plasma. The analysis was ...
Protolytic equlibria of bromazepam / Protolitičke ravnoteže bromazepama
(Srpsko hemijsko društvo, Beograd, 2002)
The protolytic equilibria of bromazepam, an ampholyte sparingly soluble in water, in homogeneous and heterogeneous systems were studied in the pH range 0–14 at 25ºC and at ionic strength of 0.1 mol/dm3 (NaCl). On the basis ...
Structural modifications of Cu(II) 12-tungstophosphoric acid salt studied by IR and Raman spectroscopy / IR i ramanska ispitivanja strukturnih modifikacija bakarne soli 12-volframfosforne kiseline
(Srpsko hemijsko društvo, Beograd, 2000)
In this paper local processes and structural phase transformations of the copper salt of 12-tungstophosphoric acid are investigated. The structural phase transformations were followed through bands, characteristic for the ...
