Pfizer Files Suit Over Fake Viagra Web Sales

Pfizer Inc. sued five Internet pharmacies and sought to seize the domain names of more than two dozen others to stop the sale of counterfeit Viagra, the top-selling male impotence drug.

Pfizer filed the lawsuits in the U.S. District Court for the Southern District of New York, Jeff Kindler, Pfizer’s general counsel, said. The New York-based company said it was working with U.S. government agencies to block the counterfeit drug sales.

Viagra’s worldwide revenue dropped 7% to $389 million in the second quarter, Pfizer reported.

Shares of Pfizer rose 25 cents to $32.45 on the NYSE.
