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 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
