What is it?

Eudragit is a family of proprietary, targeted drug release coating polymers. These polymers allow drugs to be formulated in enteric, protective or sustained-release formulations to prevent break-down of the drug until it has reached an area with adequate pH in the gastrointestinal (GI) tract. Once the drug reaches its target area of the gastrointestinal tract (i.e., duodenum, stomach) it will release from the polymer matrix and be absorbed. Targeted drug release is often used to prevent dissolution of a drug in an area where the pH is not adequate for absorption, or to help minimize gastrointestinal tract irritation.[1]
