In this work, we report synthesis and characterization of copper nanoparticles in polymer matrix by wet-chemical reduction method using ascorbic acid as reducing agent, copper (II) sulfate as metal precursor and polyvinylpyrrolidone k-30 (PVP K-30) as surfactant agent. The reaction was carried out in a high-speed stirring mixture at room temperature under nitrogen atmosphere. Characterization o...

To use the "apparent diffusion coefficient" (Dapp) as a quantitative imaging parameter, well-suited test fluids are essential. In this study, the previously proposed aqueous solutions of polyvinylpyrrolidone (PVP) were examined and temperature calibrations were obtained. For example, at a temperature of 20°C, Dapp ranged from 1.594 (95% CI: 1.593, 1.595) μm2/ms to 0.3326 (95% CI: 0. 3304, 0.334...

The objective of the present work was to develop a suitable transdermal drug delivery system for nitrendipine. Polymeric films of nitrendipine were prepared by the film casting technique (glass ring) on mercury substrate. They were evaluated for physicochemical parameters, in vitro release and ex vivo permeation (heat separated human epidermis). Release of the drug from the films followed anoma...

The objective of the present study was to improve the dissolution rate of Modafinil by solid dispersion (SD) systems in PVP-K 30. Drug contents were determined by UV Spectrophotometry at λmax of 259.5 nm. The phase solubility behavior of Modafinil in presence of various concentrations of carriers in distilled water was obtained at 37±2C. The dissolution of Modafinil increased with increasing am...

BACKGROUND AND THE PURPOSE OF THE STUDY Diclofenac sodium is a non-steroidal anti-inflammatory agent with a short biological half-life (1-2 hr) and requires multiple dosing. This research was carried out to develop and optimize diclofenac sodium loaded alginate-PVP K 30 microbeads to eliminate the need for multiple dosing and adverse effects. METHODS Diclofenac sodium loaded alginate-PVP K 30...
