Built for continuity. Focused on what matters.
In anti-infectives, what matters is not just what you make — but whether it’s there when it’s needed.
As supply chains become more complex and critical APIs disappear from Western production, continuity can no longer be taken for granted. It has to be built, maintained, and protected over time.
That is where we focus.

Xellia is a global leader in fermentation-based anti-infectives, delivering both APIs and finished dosage forms used in the treatment of severe and often life-threatening infections.
We are one of the last Western manufacturers of several essential anti-infective APIs, with EU-based production and a long-standing track record of uninterrupted supply.
Our position is not incidental. It is the result of sustained focus, deep expertise, and a commitment to staying in a category others have left. We exist to ensure that critical medicines remain available — reliably, consistently, and without interruption.
This means taking responsibility beyond production: staying ahead of evolving standards, investing in long-term capability, and working closely with our partners to anticipate and solve challenges before they impact supply.
Because in this category, delays are not just operational — they are critical.
