File this under stiff fine. The Swiss Competition Commission, which is known as WEKO, has tagged the Swiss units of Pfizer, Lilly and Bayer a total of $5.7 million for fixing the prices of their erectile dysfunction drugs - Viagra, Cialis and Levitra - through public price recommendations. These recommendations are usually made by pharmacies and medical practitioners, are illegal, Dow Jones writes. Bayer rejected the charge.

Earlier this year, WEKO concluded a 2006 investigation by deciding that the publication and observance of recommended retail prices for the pills represented illegal vertical collusion between the drugmakers and distributors. At the time, this was the biggest investigation to be undertaken by WEKO, which recommended sanctions. Whether $5.7 million in collective fines changes behavior remains to be seen.
