(AP) — A federal panel that has recently criticized efforts to cut back on painkiller prescriptions is studded with members who have financial ties to drug companies.

Nearly a third of members on the Interagency Pain Research Coordinating Committee have financial connections to makers of opioid drugs like OxyContin.

The government advisory panel consists of federal scientists, outside academics and patient representatives. Of the 18 committee members at a recent meeting to discuss the government's handling of pain issues, at least five had drug-industry connections.

One, a pain specialist from Duke University, has received thousands of dollars in payments from drugmakers, including OxyContin-maker Purdue Pharma and Teva Pharmaceuticals, which sells generic painkillers. Another, a patient advocate, holds a nonprofit position created by a $1.5 million donation by Purdue.

The revelation comes after the committee last month bashed a federal plan to recommend doctors scale back on prescribing painkillers for chronic pain. The guidelines by the Centers for Disease Control and Prevention are intended to curb deadly overdoses tied to powerful but highly-addictive opioid drugs, including Percocet and Vicodin.

At the time, various committee members called the proposal "ridiculous," ''horrible," and "shortsighted." A week later, the CDC said it would seek more public input on its guidelines — which were largely written behind closed doors.

The apparent conflicts of interest on the panel underscore the pervasive reach of pharmaceutical-industry dollars, even among federal advisers who are supposed to be carefully vetted for such connections before serving.
