Pueblos, Colorado (MEDIA TODAY) — The Pueyo Hotel Supply Co., the sole supplier of pharmaceutical drugs for Puebls emergency room, said Tuesday it has sold more than 4 million doses of OxyContin since the start of the opioid crisis.

The company has said its product has been proven to treat more than 60,000 opioid-related overdoses in Colorado and is in demand among hospital administrators, emergency room staff and patients, said Jeff Smith, the company’s president and chief executive officer.

Pueblos’ hospital administration is trying to limit the spread of the drug, Smith said.

In the last two years, emergency department visits for the opioid-use disorder have declined, the hospital system said in a report.

In Colorado, the number of overdoses for the same period in 2015 was 7,965, up about 17 percent from the previous year.

But it was down about 3 percent from 2016.

The PUEO reported its first opioid-induced overdose in 2017.

Pueyo, which was founded in 2007 by former drug dealers and heroin dealers, operates two pharmacies and a distribution center in Puebles, about 25 miles (40 kilometers) south of Denver.

The company sells OxyContin under the brand name Cephalon.

It’s the largest prescription opioid supplier in the United States.
