EUDRAGIT® polymers for solid oral dosage forms

Formulation flexibility and reliable quality – why EUDRAGIT® polymers are the gold standard for functional oral solid dosage forms.

Tried, tested and market proven, our family of EUDRAGIT® polymers offers a robust and reliable platform for functional oral solid dosage forms. In 2014 we were proud to celebrate the 60th anniversary of EUDRAGIT®. Applied as high-performance film coatings or matrices, they are designed to address your specific drug delivery requirements.

These polymers enable the API in your solid dosage form to unfold its full therapeutic potential where and when it delivers the best results.

The various polymers can be combined with each other to achieve any specific, tailor made release profile. To maximize your drug's efficacy and enhance patient compliance, we also design moisture protection and taste/odor masking functionalities into our solutions.

EUDRAGIT® polymers are copolymers derived from esters of acrylic and methacrylic acid whose physicochemical properties are determined by functional groups.

In summary: a comprehensive delivery solution platform with outstanding gastrointestinal tract targeting, along with improved protective, sustained-release and solubility performance.

Available as aqueous dispersions, organic solutions, granules and powders, EUDRAGIT® polymers provide the added benefit of easy processability. In addition, you can count on our fully synthetic, high-quality polymerization and production processes to ensure levels of quality and quality consistency that are superior to those  possible with naturally sourced polymers.

In other words:

  • Excellent batch-to-batch consistency

  • Narrow molecular weight distribution

  • Defined melt viscosity

  • Excellent thermoplastic properties

  • High thermostability

  • Superior pigment binding capacities

  • Stabilization of amorphous states in solid solutions


When it comes to targeted drug release profiles, EUDRAGIT® polymers are the pharmaceutical industry’s preferred choice. The range of EUDRAGIT® products provides full flexibility for your solid oral dosage forms.

The best of both – soluble and insoluble poly(meth)acrylates

We distinguish between two types of poly(meth)acrylates:

  • Soluble in digestive fluids by salt formation: EUDRAGIT® L, S, FS and E polymers with acidic or alkaline groups enable pH-dependent release of the active ingredient. Applications: From simple taste masking through gastro resistance to targeted release in all sections of the intestine.

  • Insoluble but permeable in digestive fluids: EUDRAGIT® RL and RS polymers with cationic and EUDRAGIT® NM polymer with neutral groups enable time controlled release of the active ingredient by pH-independent swelling. Applications: Delayed and sustained drug release.
