Phar­ma­ceu­tical companies have sought for years to protect their expensive brand-name drugs by paying generic rivals [1] handsome sums of money to put off efforts to introduce cheaper, generic alter­na­tives that could steal market share.

The contro­versial practice, known as “pay for delay,” occurs as part of patent liti­gation settle­ments and typi­cally buys a brand-name drug company more time to sell its block­buster drug exclu­sively until its patent on the drug expires. Federal Trade Commission regu­lators have said the practice costs consumers an esti­mated $3.5 billion each year [2], and have pushed for a ban.

But now it appears the drug company Pfizer is adding yet another twist to its efforts to delay generic competitors. As The New York Times reports, the company seems to have struck a deal with certain pharmacy benefit managers — the middlemen in the phar­ma­ceu­tical industry — to block generic versions [3] of Lipitor.

Lipitor, Pfizer’s block­buster cholesterol-lowering drug, is among the world’s best-selling phar­ma­ceu­ticals, and this isn’t Pfizer’s first attempt to protect it.

In 2008, the company settled patent liti­gation [4] with Ranbaxy, an Indian generic manu­fac­turer, striking a deal that guar­anteed that Pfizer would not have to face chal­lenges [5] from Ranbaxy’s generic version of Lipitor until the end of November 2011. Pfizer granted Ranbaxy some incen­tives [6] as part of the bargain but said it made no payments. Nonetheless, a group of phar­macies filed suit [7] against Pfizer and Ranbaxy last week over the deal, calling it “an extra­or­dinary ripoff” and alleging price-fixing between the two companies.

Now that it’s November 2011, Ranbaxy and other drug­makers are gearing up to offer cheaper versions of Lipitor. As The Times reports [3], Pfizer has tried to counter this compe­tition by offering big discounts on Lipitor to the middlemen that process prescrip­tions [8] for phar­macies and other buyers, giving them discounts in exchange for having them block generic versions of Lipitor for another six months. Here’s The Times:

Many drug­stores are being asked to block prescrip­tions for a generic version of Pfizer’s Lipitor starting Dec. 1, when the company loses its patent for the block­buster choles­terol drug and generic compe­tition begins.

Medco Health Solu­tions, among the nation’s largest pharmacy benefit managers, is one of the companies issuing instruc­tions, seeking to have phar­ma­cists keep filling prescrip­tions with the more expensive Lipitor for six months.

See some of those instruc­tions [9] sent to phar­macies by the pharma middlemen. The docu­ments were released by Phar­ma­cists United for Truth and Trans­parency, a group of inde­pendent phar­ma­cists. (We first noticed them posted at the blog Phar­malot [10].)

According to the group, Pfizer’s plan would mean that customers at the phar­macies serviced by these middlemen would receive Lipitor even when they’ve been prescribed a generic version. Because Lipitor co-pays would also be reduced to the level of generic co-pays, customers might not notice, but employers and Medicare Part D would pay the same amount as before, despite the avail­ability of a cheaper alternative.

A Pfizer spokesman gave The Times a statement saying that the company was committed to ensuring that customers had access to Lipitor but declined to answer addi­tional ques­tions. We’ve also asked Pfizer for comment and will update when we hear back.
