Colorcon® offers advanced film coating systems for extended/controlled release dosage forms. While there are multiple solutions available for barrier membrane extended/controlled release technologies, Colorcon’s best-in-class polymer products are complemented by our value-added services which support all phases of product design and development.
Extended/controlled release technologies from Colorcon use unique combinations of polymers to encapsulate active drug compounds and control release of the drug at varying rates. Through advanced technology, our extended/controlled release products simplify the development and production process for tablets and capsules while providing consistent rates of drug release.
Colorcon now has two robust options for extended/controlled release barrier membranes:
Surelease® Aqueous Ethylcellulose Dispersions
Designed for extended/controlled release multi-particulate, tablet and taste masking applications, Surelease is an easy-to-use, totally aqueous coating system using ethylcellulose as the release rate controlling polymer. The dispersion provides the pharmaceutical formulator with flexibility to adjust drug release rates in the design of extended/controlled release technologies.
Surelease NG is Colorcon’s latest system addition, offering enhanced stability over time, improved reproducibility and extended shelf life (24 months).
ETHOCEL™ Premium Ethylcellulose Polymers
Available in a range of viscosity grades, ETHOCEL™ premium ethylcellulose polymers have ideal properties for use in a variety of pharmaceutical applications. ETHOCEL™ (ethylcellulose) polymers are most frequently used as barrier membranes to achieve extended/controlled release in multi-particulate formulations. ETHOCEL™ is among only a very small number of water-insoluble polymers that are approved and accepted globally for pharmaceutical applications. Colorcon’s global technical service infrastructure and applications expertise complements the ETHOCEL™ product line and is available for servicing your formulation needs at every step of the drug development process.
