Portfolio Overview

Discover our solutions for sustained release drug delivery

TheraPEA™ biodegradable polyester amides

This highly degradable polymer enables you to create formulations with near-linear sustained release rates - from weeks to six months-plus - thus unlocking the potential for lower dosing frequency in patients. 

  • TheraPEA™ is a highly biocompatible polymer, proven in ophthalmic, intravascular, and intra-articular applications. 
  • It enables controlled degradation kinetics without acidification of the microenvironment – making it highly compatible with pH sensitive Active Pharmaceutical Ingredients.


Medical polyurethanes

Our biostable polyurethanes have a proven track record in sustained release drug delivery – and are compatible with a wide range of specific Active Pharmaceutical Ingredients (hydrophobic, hydrophilic small molecules, biologics). We can further support you here with:

  • The potential for mechanical properties ideal for creating flexible polymeric drug delivery applications.
  • Deep organizational knowledge of melt-and-solution processing of polyurethanes.
  • A proven clinical history in medical devices.
  • FDA Master Files and support for global regulatory filings.

Application spotlight: Drug delivery that benefits all

What is your ideal drug delivery solution? At DSM Biomedical we believe it’s one that benefits all - our partners, patients, and the planet.

Today, our experts are helping to make this a reality through our TheraPEA™ polyester amide platform, which enables sustained drug release, in a more sustainable way. That means multi-month, controlled release; and a zero-order degradation profile – with good correlation in-vitro and in-vivo up to 180 days. 

TheraPEA™ is compatible with even the most challenging APIs – unlocking the potential for bold new drug delivery solutions that can improve clinical outcome for patients, deliver better healthcare economics for providers, and boost sustainability by creating significantly less medical waste.

We create sustainable healthcare solutions that deliver tangible and valuable sustainability benefits to our partners – with no compromises on safety or performance.
