The CMA has fined pharma companies Pfizer and Flynn Pharma nearly £90 million for charging excessive prices to the NHS for an anti-epilepsy drug.
The Competition and Markets Authority (CMA) has imposed a record £84.2 million fine on the pharmaceutical manufacturer Pfizer, and a £5.2 million fine on the distributor Flynn Pharma after finding that each broke competition law by charging excessive and unfair prices in the UK for phenytoin sodium capsules, an anti-epilepsy drug. The CMA has also ordered the companies to reduce their prices.
The fines follow prices increasing by up to 2,600% overnight after the drug was deliberately de-branded in September 2012. For example, the amount the NHS was charged for 100mg packs of the drug rocketed from £2.83 to £67.50, before reducing to £54.00 from May 2014. As a result of the price increases, NHS expenditure on phenytoin sodium capsules increased from about £2 million a year in 2012 to about £50 million in 2013. The prices of the drug in the UK have also been many times higher than Pfizer’s prices for the same drug in any other European country.
