Pharma polymers improve patient compliance

Roehm Pharma Polymers, a business line within the specialty acrylics business unit of Duesseldorf-based Degussa, focused on the role of polymers in ensuring patient compliance.

The company's range of EUDRAGIT polymers is said to be ideally suited for manufacturing enteric tablet coatings and for sustained release formulations, as well as taste-masking. New product developments for controlled drug release in the digestive tract enable the use of highly sophisticated coating processes and innovative drug delivery techniques.

EUPERGIT is a carrier material for immobilising enzymes and offers a cost-effective alternative to production processes based on conventional methods of synthesis, the company says. The stable covalent binding of the enzyme to the oxirane groups of the carrier is crucial for the stability and repeated use of the immobilised enzyme.

For transdermal drug delivery, Rohm Pharma Polymers has developed the pressure-sensitive matrix PLASTOID. Its pronounced hydrophilicity ensures good compliance with the skin. Further fields of application are as film-formers for externally applied pharmaceutical products, and as liquid wound dressings (sprays).
