Sterile APIs

High performance microfiltration technology

Euticals manufactures bulk sterile APIs to cGMP standards in Bon-Encontre and Tonneins. Euticals provide a complete range of synthesis capabilities for sterile API projects, from raw materials through regulated early and late stage intermediates to bulk APIs. We also offer advanced building blocks based on proprietary, leading technologies that can be used in all of these synthesis situations. Our sterilization capability can be integrated with API production or operate as a separate outsourced step for companies that do not have bulk sterile facilities or who may need additional capacity. Our Tonneins location was expanded in 2002 to include a sterile pilot plant and a Class A cleanroom handling facility. Our Isolated facilities are located on sites with a range of chemistry capabilities that are flexible in size and scope and even allow the handling of hazardous reagents in chemical syntheses. This allows us to integrate API synthesis, whereby the overall synthesis and process chain can be made more efficient, such as final purification during the sterilization process. 

Microfiltration advantages

At Euticals, sterilization is accomplished by high performance microfiltration. This technology is often used with powder, which is dissolved, filtered and crystallized. Microfiltration is fundamentally different from traditional sterilization methods in that it is non-destructive. We have experience in precisely controlling the physical properties of the final product, with many options available.

Quality is assured

Our sterile API teams have more than a decade of experience with creating the appropriate conditions for the media fill and process validation even for very difficult to handle or sensitive products. Our QA follows strictest FDA, ICHQ7A and ICHQ1A guidelines and our QC is able to determine all relevant parameters. Our plant, especially in the aseptic processing area, uses a system of airlocks and cleanroom zones from class D through class A in the product zone.
