The European Union has fined two pharmaceutical companies for colluding to keep a cheap alternative to a sleep disorder medicine off the market for their profit and at the expense of patients.

EU antitrust commissioner, Margrethe Vestager, said that Teva pharmaceuticals and Cephalon, a company it later acquired, must pay 60.5 million euros ($72 million) for agreeing between themselves to delay for years the launch of Teva’s cheaper version of Cephalon’s blockbuster Modafinil. In return for the delay, Teva got beneficial side deals and some payments.

Vestager said that “Teva’s and Cephalon’s pay-for-delay agreement harmed patients and national health systems, depriving them of more affordable medicines.”
