What we make is medicine. And those medicines, they make a difference.

All of us at Cornerstone Therapeutics share a common goal — a passion, if you will — to make quality medicines. And through those medicines, to improve quality of life.

You'll find that commitment behind every product we offer — such as Zyflo CR^®, Spectracef^® and the AlleRx^® Dose Pack family — and behind those we have in development.

These trusted respiratory medicines are a true reflection of our mission at Cornerstone — to make, and continually improve, quality products. To boost patient compliance. To increase efficacy. And more importantly, to help patients live better, more active lives.
