    Kollicoat® SR 30 D

    Precise, pH-independent sustained release for multiple applications

    Kollicoat® SR 30 D is a low-viscosity, non-sticky aqueous dispersion of polyvinyl acetate. Whatever the dosage form, this innovative coating releases active ingredients precisely and evenly over a period of time, at any pH. It exhibits a high binding capacity and excellent film-forming properties – simplifying production and ensuring exceptionally flexible coatings. Kollicoat® SR 30 D produces consistent results across multiple formulations: whether deployed as a film coating for extruded or drug-layered pellets, used to coat and com-press multi-particulate single units into tablets, or for granulating and compressing non-erodible sustained-release matrix tablets.

    Why choose Kollicoat® SR 30 D?
    Reliable sustained release at any pH
    First aqueous polyvinyl acetate dispersion
    High resistance to mechanical stress
    New life cycle management opportunities

    Controlled Release: A New Paradigm with Polyvinyl Acetate Polymer

    Controlled release (CR) has been a subject of continued interest, and the pharma industry is taking a closer look into release profiles of drugs because of risk factors associated with early release (dose dumping) before being delivered to intended sites to achieve the desired efficacy, and to overcome toxicity and drug abuse issues. The latter has become more challenging, especially in controlled delivery of opioids in pain management. Nonetheless, the former one is also poorly understood because of complexity associated with the mechanism of controlled release from a particular dosage.

    Product Innovation on Modified Release Coatings (Sustained Release and Enteric Coatings)

    Developing modified coatings that produce a reliable and stable release is still a challenge. Only a few polymers - polyvinylacetate, ethylcellulose and methacrylates - are suitable for this purpose and have very different characteristics. In this webinar, you will gain an in-depth knowledge about the relevant requirements for modified release coatings and how they can be fulfilled, for instance by choosing a suitable polymer, the proper formulation and the best process parameters.

    Best Practices to Overcome Softgel Coating Challenges

    Soft gelatin capsules (softgels) have become an increasingly popular method for the delivery of pharmaceuticals and dietary supplements due to to the ability to encapsulate sensitive compounds, accurately deliver potent molecules, and directly appeal to the consumer. However, applying a functional coating to softgels is a challenging endeavor requiring precise formulation and finely tuned processing parameters that only recently have been explored. In this webcast,  pharmaceutical scientists and formulators will learn about key aspects of successful softgel coating processes. Discussion topics include:
