Abstract This study investigates the effects of micro-environment modification and polymer type on the in-vitro dissolution behavior and in-vivo performance of micro-environment pH modifying solid dispersions (pHM-SD) for the poorly water-soluble model drug Toltrazuril (TOL). Various pHM-SDs were prepared using Ca(OH)2 as a pH-modifier in hydrophilic polymers, including polyethylene glycol 6000 (PEG6000), polyvinylpyrrolidone k30 (PVPk30) and hydroxypropyl methylcellulose (HPMC). Based on the...

Abstract An experimental design was established in order to optimize the mechanical properties of two oral film formulations intended for oral delivery of bioactive compounds. Carboxymethylcellulose (CMC) and gelatin type A (GelTA) were selected as polymeric matrix. Scanning electron microscopy revealed that caffeine crystals were homogeneously dispersed onto oral film matrix. Fourier-transform infrared analysis did not indicate formation of new chemical entities. USP modified dissolution assay...

Context: We previously designed, developed and characterized a novel microencapsulated formulation as a platform for the targeted delivery of Probucol (PB) in an animal model of Type 2 Diabetes. Objective: The objective of this study is to optimize this platform by incorporating Chenodeoxycholic acid (CDCA), a bile acid with good permeation-enhancing properties, and examine its effect in vitro.
