Our Company
Who We Are
We’re Par Health, the essential pharmaceutical company.
Becoming Par Health: Our Story
Par Health was born from the merger of Mallinckrodt and Endo—two legacy companies with over a century of experience in essential medicines. Both began as family-run businesses, united by a commitment to integrity and innovation.
Our manufacturing footprint includes the historic API site in St. Louis, Missouri—founded over 150 years ago by three brothers with a bold vision. It remains central to our operations today. We also carry forward the legacy of our Rochester, Michigan facility, which earned the first FDA Biologics license for polio vaccine manufacturing.
These sites are joined by eight additional facilities across the US and India, forming a global manufacturing and supply network that delivers high-quality medicines with consistency and scale.
This history isn’t just behind us—it fuels our purpose today.
It’s why we manufacture every product with precision and intention. So, when patients need treatment, providers can trust our medicines to meet their needs and support better outcomes. And when it’s time to deliver, we show up: responsibly and reliably.
Our standards are never static. We raise them to meet the moment—so we’re the partner people can count on, from everyday treatments to critical needs.
Because for medicine to do its job, we must be excellent at ours.

We believe great healthcare is built on getting the essentials right.
