Polymers for Controlled Release

Through our global Controlled Release Alliance with Dow Pharma and Food Solutions, 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 Dow Pharma and Food Solutions' products: ETHOCEL™ premium ethylcellulose polymers, METHOCEL™ premium cellulose ethers CR (hypromellose or HPMC) and POLYOX™ water-soluble resins. Dow Pharma and Food Solutions 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.
