Application

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

The objective of this study was to obtain pH-independent release profiles from coated pellets containing drugs with pH-dependent solubility. pH-independent release of the basic model drug verapamil HCl was achieved by coating with a combination of the neutral polymer dispersions

The major aim of this study was to identify an efficient tool to adjust drug release patterns from aqueous and organic ethylcellulose (a gastrointestinal insoluble polymer) coated pellets and to evaluate the long term stability of the film coatings. Drug
