Using the playbook of Mylan, Turing and, well, their own company, Valeant Pharmaceuticals has hiked the price of yet another life-saving treatment to astronomical values. This time, it's calcium EDTA, a lead poisoning treatment that cost US hospitals and poison control centers about $500 for a packet of six ampules (6 grams) before 2012, when Valeant acquired the drug. Poison control experts now say that US centers pay about $5000 per gram for the drug, compared to $15 per gram for Canadians. In a 6-year period ... Valeant increased the US price of the drug by as much as 7200%. Two physicians - Michael Kosnett from the University of Colorado School of Medicine and Timur Durrani at the University of California, San Francisco (UCSF) - expressed their concerns about these price hikes in a letter to U.S. Rep. Elijah Cummings (D-Md), the ranking member of the House Committee on Oversight and Government Reform. According to Kosnett and Durrani, the average price per milliliter for the drug went from $18.57 in 2008 to $1346.37 in 2014. U.S. hospitals have no other source for calcium EDTA. Most of those who develop acute lead poisoning are children. The effects of lead poisoning are lasting and profound. Calcium EDTA is on the World Health Organization's Model List of Essential Medicines, which lists medications that are most critical for a healthcare system to have on hand.
