Impact of Excipients Blending on Sugar-Stabilized Therapeutic Proteins
Abstract
Sugars have long been used as stabilizing excipients for protein-based therapeutics during the development and production process. Incorporating stabilizing agents, such as sucrose and trehalose into dry formulations is a common strategy approved by the US FDA. However, single-sugar…

Evaluation of Polyvinyl Alcohol as Binder during Continuous Twin Screw Wet Granulation
Binder selection is a crucial step in continuous twin-screw wet granulation (TSWG), as the material experiences a much shorter residence time (2–40 s) in the granulator barrel compared to batch-wise granulation processes. Polyvinyl alcohol (PVA) 4-88 was identified as an effective binder during…
