Successful drug discovery and development of new therapeutics is a long, expensive multidisciplinary process needing innovation and the integration of smart cutting edge science and technology to overcome the challenges in taking a drug from the bench to the bedside. The research activities of the Pharmaceutical Biochemistry group span the drug discovery and development process, providing an i...

The aim of this study was to evaluate hot-melt extrusion (HME) as a continuous process to form cyclodextrin (CD) inclusion complexes in order to increase the solubility and dissolution rate of itraconazole (ITZ), a class II model drug molecule of the Biopharmaceutics Classification System. Different CD derivatives were tested in a 1:1 (CD:ITZ) molar ratio to obtain CD ternary inclusion complexe...

Development of an oral in vivo predictive dissolution medium for acid drugs with a pKa in the physiological range (e.g., Biopharmaceutics Classification System Class IIa) requires transport analysis of the complex in vivo CO2 /bicarbonate buffering system. In this report, we analyze this buffer system using hydrodynamically defined rotating disk dissolution. Transport analysis of drug flux was ...

Materials chemistry has been fundamental to the enormous field that encompasses the delivery of molecules both to desired sites and/or at desired rates and durations. The field encompasses the delivery of molecules including fertilizers, pesticides, herbicides, food ingredients, fragrances and biopharmaceuticals. A personal perspective is provided on our early work in this field that has enable...

The main objective of this work was to investigate in-silico predictions of physicochemical properties, in order to guide oral drug development by provisional biopharmaceutics classification system (BCS). Four in-silico methods were used to estimate LogP: group contribution (CLogP) using two different software programs, atom contribution (ALogP), and element contribution (KLogP). The correlatio...
