General description

With formulation challenges in mind, we have used particle engineering technologies to develop functional excipients specifically for solid oral dosage forms. The products in our Parteck® portfolio feature unique particle properties tailored for excellent performance in tableting processes, for specific drug delivery technologies, or for solubility enhancement.
As part of our Emprove® Program, our raw materials are offered with extensive documentation facilitating compliance of your pharma and biopharma product, full supply chain transparency and risk mitigation. Our SAFC® portfolio of high-quality products for biopharmaceutical and pharmaceutical formulation and production withstands strict quality control procedures and is produced according to applicable cGMP guidelines.


Parteck® PLX 188 excipient combines adequate lubrication at tolerable concentrations with the added benefit of dissolution enhancement. It features consistent performance, improved dissolution rate and reliable lubrication – all at the same time. As a result, Parteck® PLX 188 excipient can therefore provide a simple solution to low bioavailability of DCS 2a compounds.
