GSK fined after anti-depressant sales probe in Britain

The CMA ruled the payments and other value transfers were aimed at delaying the potential entry of generic competitors into the British market for paroxetine.

The CMA said: "The CMA has also found that GSK's conduct, in making payments to GUK, Alpharma and one further company, Norton Healthcare Limited (IVAX), to induce them to delay their efforts to enter the UK paroxetine market independently of GSK, infringed the competition law prohibition on abuse of a dominant position."

The CMA imposed fine of 37,606,275 pounds ($54,581,747) on GSK. A fine of 5,841,286 pounds ($8,478,042) was imposed on Merck KGaA (GUK's former parent) and GUK. A fine of 1,542,860 pounds ($2,239,307) was imposed in respect of Alpharma's infringement.

Michael Grenfell, the CMA's enforcement director, said: "Today's decision sends out a strong message that we will tackle illegal behaviour that is designed to stifle competition at the expense of customers -- in this case, the NHS and, ultimately, taxpayers."

Seroxat was one of GSK's best-selling medicines and was used to treat, among other conditions, depression and anxiety disorders.
