Senator demands docs from big pharma as she probes their role in opioid epidemic

"This epidemic is the direct result of a calculated sales and marketing strategy major opioid manufacturers have allegedly pursued over the past 20 years to expand their market share and increase dependency on powerful - and often deadly - painkillers," Sen. Claire McCaskill (D-MO) says

Sen. Claire McCaskill of Missouri demanded information Tuesday from five top opioid manufacturers, saying she would investigate their alleged role in the drug epidemic responsible for more than 200,000 overdose deaths since 2000.

“This epidemic is the direct result of a calculated sales and marketing strategy major opioid manufacturers have allegedly pursued over the past 20 years to expand their market share and increase dependency on powerful – and often deadly – painkillers,” McCaskill, who is the ranking Democrat of the Homeland Security and Governmental Affairs Committee, wrote to company executives. “To achieve this goal, manufacturers have reportedly sought, among other techniques, to downplay the risk of addiction to their products and encourage physicians to prescribe opioids for all cases of pain and in high doses.”

McCaskill sent letters to Purdue Pharma, Janssen Pharmaceuticals, Insys Therapeutics, Mylan and Depomed, which she said make the top-five-selling prescription painkillers. She is seeking sales and marketing materials, any studies the companies might have conducted about the addictive properties of their drugs, information on compliance with legal settlements and figures on donations to advocacy groups.

McCaskill said she wants to know whether manufacturers have contributed to overuse and overprescribing of opioids. According to the Centers for Disease Control and Prevention, nearly 180,000 people have died of overdoses of prescription opioids since 2000 and tens of thousands more have succumbed to overdoses from heroin and fentanyl.

Earlier this month, McCaskill asked the Justice Department’s inspector general to investigate why the Drug Enforcement Administration had delayed or blocked enforcement efforts against wholesale distributors of opioids accused of failing to follow laws designed to keep legal painkillers from reaching the black market. She cited reporting by The Washington Post that the efforts of DEA field investigators had been frustrated when attorneys at headquarters imposed higher burdens of proof for bringing cases, even as the overdose rate from those prescription drugs soared.

The city of Chicago and several U.S. counties have sued opioid manufacturers, demanding reimbursement for the expense of grappling with the drug crisis. The lawsuits contend that aggressive marketing by the companies has fueled the crisis.

Last year, Mylan was accused of price-gouging after it sharply raised the price of its lifesaving EpiPen injection medication for allergic reactions. The company released a lower-cost generic version of the device in response.
