Hypromellose, Ethylcellulose, and Polyethylene Oxide Use in Hot Melt Extrusion
January 1st 2006Hot melt extrusion (HME) formulation development depends heavily on choosing the appropriate polymers. This article reviews HME process parameters and highlights three polymers in HME: polyethylene oxide, ethylcellulose, and hypromellose.
Essentials of Validation Project Management
January 1st 2006In the second half of this two-part series, the author suggests that to qualify and validate a pharmaceutical manufacturing facility, one must coordinate protocol and SOP development, scheduling and implementation, turnover package preparation, and the management and resolution of deviations and discrepancies. In combination with the programs described in Part I, these activities will help deliver projects on schedule, at estimated cost, and with quality assured.
