Celanese Presents Cutting-edge Pharmaceutical Copolymer At 2016 AAPS Annual Meeting And Expo

Celanese Corporation (NYSE: CE), a global technology and specialty materials company, will present its EVA pharmaceutical material solutions at the 2016 AAPS Annual Meeting and Exposition November 13-17 at the Colorado Convention Center in Denver. Celanese will exhibit its pharmaceutical controlled release copolymer, VitalDose® ethylene vinyl acetate (EVA), at booth 1604.

Celanese material experts will discuss the latest developments in pharmaceutical material science and how EVA is being used in new drug delivery innovations. VitalDose® EVA controlled release excipients deliver reliable performance with customizable release properties that are compatible with many active pharmaceutical ingredients (APIs).

When formulating thermally sensitive APIs with excipients in the hot melt extrusion process, one of the major challenges is to make sure the APIs do not go through any thermal degradation. This will not only provide cost savings but also ensure the chemical integrity of the APIs during processing. Due to their intrinsic low melting points, broad melting ranges, and sheer thinning characteristics, EVA excipients provide outstanding low temperature processability along with their excellent controlled release properties and biocompatibility.

To help formulation scientists understand the processability temperature ranges of EVA excipients, Celanese has conducted experiments to show the minimum compounding temperatures of EVA excipients with vinyl acetate contents ranging from 9% to 40%. At AAPS, Celanese will demonstrate experiments of a tunable controlled release of Niacin with EVA excipients prepared by a low temperature hot melt extrusion process. The information provided with this original research will help formulation scientists better address the challenges in formulating thermally sensitive drugs by using EVA excipients.

Celanese will be presenting a poster session at the 2016 AAPS Annual Meeting and Exposition highlighting EVA's processing advantages for drug formulators.
