Specialists in infectious disease are protesting a gigantic overnight increase in the price of a 62-year-old drug that is the standard of care for treating a life-threatening parasitic infection.The drug, called Daraprim, was acquired in August by Turing Pharmaceuticals, a start-up run by a former hedge fund manager. Turing immediately raised the price to $750 a tablet from $13.50, bringing the annual cost of treatment for some patients to hundreds of thousands of dollars.

Although some price increases have been caused by shortages, others have resulted from a business strategy of buying old neglected drugs and turning them into high-priced “specialty drugs.”

Cycloserine, a drug used to treat dangerous multidrug-resistant tuberculosis, was just increased in price to $10,800 for 30 pills from $500 after its acquisition by Rodelis Therapeutics. Scott Spencer, general manager of Rodelis, said the company needed to invest to make sure the supply of the drug remained reliable. He said the company provided the drug free to certain needy patients.

Doxycycline, an antibiotic, went from $20 a bottle in October 2013 to $1,849 by April 2014, according to the two lawmakers.

The Infectious Diseases Society of America and the HIV Medicine Association sent a joint letter to Turing earlier this month calling the price increase for Daraprim “unjustifiable for the medically vulnerable patient population” and “unsustainable for the health care system.” An organization representing the directors of state AIDS programs has also been looking into the price increase, according to doctors and patient advocates.
