title: Polymer-ceramic Monolithic In-Needle Extraction (MINE) device: Preparation and examination of drug affinity.
abstract: Polymer-ceramic materials were placed in the in-needle device. Polymer-ceramic Monolithic In-Needle Extraction (MINE) device is an extraction device used in sample preparation step but, on the other hand, it can be a tool for examination of interactions between potential antiresorptive drugs and bones. MINE device was used as tool for determination of bisphosphonate affinity to hydroxyapatite. Spectra of prepared materials containing different proportion of the ceramic part were performed with the use of Fourier transform infrared spectroscopy. The extraction of sodium risedronate as standard compound from simulated body fluids was carried out by pumping liquid samples through the MINE device. The amount of sodium risedronate in solutions was examined using UV-VIS spectroscopy. The sorption results of sodium risedronate obtained for monolithic materials containing different amount of hydroxyapatite were compared to the values determined for pure (bulk) hydroxyapatite. Sorption capacity for polymer-ceramic materials placed in the in-needle extraction device was about 0.39mg of sodium risedronate. The complete desorption process was carried out at the level over 95% using various eluents. The results of sorption-desorption experiments allow to deduce on the affinity of sodium risedronate to the ceramic part of sorbent (hydroxyapatite).
