Looks like Pfizer has lost another lawsuit involving Prempro (combination of Pemarin, which is horse urine, and progestin, which is fake progesterone). Check out this article from Bloomberg Business News.

I think it is very telling that the judge is planning to award punitive damages in this case, saying that Wyeth Pharmaceuticals (bought out about 5 years ago by Pfizer) was reckless In their handling of the drug, and did not accurately present the risks and benefits of the drug to the patient (she developed breast cancer). Why Premarin and Prempro are still on the market is absolutely beyond me, and why doctors are still prescribing it, when there are far safer alternatives, is just ridiculous.
