120 years of API manufacturing. 500 Partners. We are Xellia.
Relationships built over 120 years don't happen by accident. They happen because people choose to show up, every day, for the work that matters.
For over 120 years, we've been doing one thing: making the anti-infective medicines the world depends on.
Not because it's easy. Fermentation-based manufacturing is painstaking work — part science, part craft, part patience. The molecules we produce are too complex to be made any other way. They grow in fermentation tanks tended by people who've spent years learning exactly when to intervene and when to wait.
That's why more than 500 pharmaceutical companies in 80 countries trust us with their supply. Not because we're the biggest. Because we show up. Because when you call us, you get people who understand your timelines, your patients, and your problems — and who treat them as their own.
But 120 years of showing up isn't a reason to stand still. It's a reason to go further. We want to be the world’s leading supplier of APIs. We're expanding our portfolio, broadening our reach, and building the partnerships to deliver more therapies to more patients around the globe — because the world's need for reliable anti-infectives isn't slowing down, and neither are we.
DUPHARM & Xellia - a life-saving partnership
A Friday evening. A phone call. A life saved.
It was a Friday evening in the Emirates. The working week was over. Businesses had closed their doors. People were heading home for the weekend.
Then the phone rang.
A local hospital had a patient in the ICU in a life-threatening situation. They needed Daptomycin — and they needed it now.
Our distribution partner in the UAE, DUPHARM, didn't hesitate. Within hours, the medicine was at the hospital. The patient's life was saved.
But here's what made that possible: it wasn't a logistics miracle. It was years of trust.
Xellia and DUPHARM, have built a partnership grounded in one shared belief — that when lives are on the line, "we'll figure it out" isn't good enough. You need to know, before the call ever comes, that the medicine will be there.
That kind of certainty doesn't come from a supply agreement. It comes from people. From our man on the ground, Tamer Medhat, working side by side with the DUPHARM, team to make sure Daptomycin is always available locally — not in a warehouse overseas, but right there, ready, when it matters most.
A Friday evening. A phone call. A life saved.
That's what relationships make possible.
