Turing Pharmaceuticals chief executive Martin Shkreli found himself in the middle of a media firestorm last month as he adamantly defended his company's 4,000 percent drug price hike. Daraprim, which treats a life-threatening infection in patients with HIV/AIDS and other immune problems, was increased to $750 a pill, a move resoundingly decried. Now, another company will offer a Daraprim alternative, at just $1 a pill. It's not an exact replica of Daraprim. San Diego-based Imprimis Pharmaceuticals announced Thursday that it is selling pills containing a "customizable compounded formulation" of pyrimethamine and leucovorin, both ingredients in Daraprim. The Food and Drug Administration doesn't approve compounded drugs, such as this one offered by Imprimis. Typically, compounded drugs are prescribed to patients who can't take FDA-approved drugs, such as for those who are allergic to an inactive ingredient. Compounded drugs are no stranger to controversy; a compounding pharmacy was at the heart of a deadly meningitis outbreak in 2012 that killed 64 people and sickened more than 600. Federal legislators subsequently tightened regulations over such companies. And compounded drugs can be very pricey, too. But it appears the Daraprim alternative compound was not born out of a physical inability to use Daraprim, but a financial one.
