Pfizer's Long-Shot Lipitor Gamble

If an article from The Wall Street Journal about Pfizer's (NYSE: PFE  ) plan to get an over-the-counter version of Lipitor approved is correct, big pharma is likely fighting a losing battle. On the other hand, considering the potential payoff, the time and money invested could be worth it, long shot or not.

Switching to over-the-counter status has been very lucrative for allergy pills such as Johnson & Johnson's (NYSE: JNJ  ) Zyrtec and Merck's (NYSE: MRK  ) Claritin. Switching Sanofi's (NYSE: SNY  ) Allegra to over-the-counter status was the motivation behind the company buying Chattem. Heartburn medications such as Procter & Gamble's (NYSE: PG  ) Prilosec OTC and Takeda's Prevacid 24HR have also been big winners.

But allergies and heartburn are fairly easy to self-diagnose. Diagnosing high cholesterol is considerably harder for people who lack a machine capable of doing blood tests in their homes.

Merck failed to get approval of an over-the-counter version of its statin, Mevacor, for exactly that reason. According to the Journal, 30% of patients who thought they should take the drug really wouldn't benefit. The FDA won't risk needlessly exposing those patients to the side effects of Lipitor, even if they are relatively mild.

And for patients that actually did need a cholesterol-lowering drug, how would patients know if the drug was working? If you're going to have to see a doctor to get lab work done, the doctor can just write a prescription. Lipitor is headed for generic competition in November, so that scenario is no longer beneficial to Pfizer. Unfortunately the FDA isn't going to take that into account.

Since this was only an article citing "people familiar with the matter," it's a little hard to know what Pfizer's exact plans are. Assuming it keeps the costs of exploring this idea to a minimum, the downside seems reasonable. I have a hard time seeing this going anywhere, but given the potential payoff, it's probably worth the risk.

    The side effects of statins are not mild and highly under reported by big Pharma. Moreover, recent studies are bringing the whole lipid theory of heart diesease into question. In fact, the latest large scale study of cholesterol levels and heart attacks in Britan suggests that statins do not protect by lowering LDL, but some other mechanism unrelated to cholesterol levels.

    In the mean time, big pharma will feed off the teats of this cash cow as long as possible.

    In a few years, the market for statins may shrink to a fraction of what it is now. Estimates are that only 30% of those taking statins benefit from them. If the real mechanism of how statins help with arterial blockages is discovered, statins will be just a memory of a discredited theory.
