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 we aim to improve quality of life.

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

Our trusted respiratory medicines are a true reflection of Cornerstone's mission — to make quality medicines — and to continually make them better; to boost patient compliance; to increase efficacy. More importantly, to help patients live better, more active lives.
