The Centers for Disease Control and Prevention (CDC) has been accused of bowing to drug industry pressure after releasing new guidelines that doctors say put lives at risk by rowing back on warnings about the dangers of opioid prescribing. The latest CDC guidelines have caused controversy after dropping specific limits on dosages and lengths of prescribing from a key summary of recommendations used by physicians. Dr Andrew Kolodny, president of Physicians for Responsible Opioid Prescribing, sees the drug industry's hand behind the change. Kolodny has testified against opioid makers in legal actions over their part in driving the opioid epidemic by pushing sales with false claims about their safety and effectiveness. They include Purdue Pharma, manufacturer of OxyContin, a powerful narcotic pill that kickstarted the US's opioid epidemic alongside the company's marketing strategy to see the drugs widely prescribed. Kolody said ... that the drug industry calculated how much the 2016 CDC guidelines would cost it if doctors followed the recommendations to limit prescribing of high dosage pills. "The highest dosage products have had the highest profit margin. It only costs a few extra pennies to make the higher dosage pill, but retail it's almost double what they get per pill or prescription. So the industry fought very hard to block the release of the 2016 guideline and when that failed they did everything they could to make the guidelines appear controversial. And that worked," he said.
