Until this week most of us had never heard of Daraprim, a drug that fights toxoplasmosis. But after the decision of the drug's new owner, Turing Pharmaceuticals, to boost its cost per pill from $13.50 to a whopping $750, we're all unlikely to forget its name or the name of Turing's owner, 32-year-old Martin Shkreli. The outrage over the astronomical hike in a life-saving drug has opened the doors to a ... debate about the soaring costs of prescription medications in the United States. Daraprim ... has been around since the 1940s. Logic suggests that drugs that have been around for a while should decline in price. It turns out that isn't the case. The profit-minded individual or company snaps up the patents, suddenly hikes the drug's price and puts consumers - from insurance companies to individuals - in a position of either paying what is demanded or going without. Late this summer, Rodelis Therapeutics boosted the cost of 30 tablets of cycloserine, a tuberculosis drug, from $500 to $10,800. Early in the year, Valeant Pharmaceuticals International Inc boosted the prices of two heart drugs, Nitropress and Isuprel, by 525% and 212% on the same day that they acquired them. "Our duty is to shareholders and to maximize the value" of Valeant's products, a company spokeswoman told the Wall Street Journal at the time.
