應用
Kollicoat polymers can be employed as film coatings (intelligent surfaces) with controlled-release agents, for instant-release or sustained-release applications. Kollicoat polymers can be used with all standard coating equipment and are cost-effective, delivering maximum quality in terms of function, stability, and appearance. This research grade product is intended for use in R&D and development only.

The drug substance SAG/ZK has a short biological half-life and because of its weakly basic nature a strong pH-dependent solubility was observed. The aim of this study was to develop a controlled release (cr) multiple unit pellet formulation for SAG/ZK
