Celanese Whitepaper
EVA in Controlled Release

A whitepaper: Predictive Modeling and Validation of Tamoxifen Release from EVA Copolymers, is available for download.

Details of the study: As a unique and important controlled release excipient, EVA was evaluated in the study with selected active pharmaceutical ingredients (API). The API solubility and release profiles were studied using Hansen Solubility Parameter calculations and experimental in vitro elution. The paper demonstrates a method that can be used for initial formulation design for controlled drug delivery from EVA copolymers.
