Controlled Release Alliance
Through our global Controlled Release Alliance with DuPont, Colorcon offers an enhanced portfolio of polymers for controlled release drug delivery systems along with application expertise to meet customers’ formulation needs and help speed their products to market.
The CR Alliance includes the exclusive global distribution rights for DuPont products: ETHOCEL™ premium ethylcellulose polymers, METHOCEL™ premium cellulose ethers CR (hypromellose or HPMC) and POLYOX™ water-soluble resins. DuPont offers more than 50 years of experience in production of hypromellose (HPMC), which is the most trusted and widely used polymer for use in controlled release drug delivery systems.
ETHOCEL, METHOCEL and POLYOX polymers offer an outstanding range of controlled release properties for a variety of dosage forms and processing methods. Variations in molecular weights and chemical substitutions provide multiple ways to optimize formulation performance. Each range has fundamentally different hydrophilicity, swelling and erosion characteristics, to provide flexibility in control of the main mechanisms of release.
From January 2017, Colorcon represents AFFINISOL™ Solubility Enhancing Polymers, AMBERLITE™ and DUOLITE™ Ion Exchange Resins™ for pharmaceutical applications.
From April 2019 Colorcon will also represent Aquacoat® ECD for Sustained Release and Aquacoat® CPD for Enteric Coating Applications.
Contact Colorcon to learn more about rate controlling polymers for extended/controlled release drug delivery systems and how our HyperStart® Formulation Service can get your product to market faster and more efficiently.
