The latest casualty among drugs falling victim to over-promotion and under-testing is Bextra, Pfizer’s COX-2 inhibitor. This time around it is not just cardiovascular issues that are the problem.
Bextra appears to be linked to a significantly higher incidence of a serious skin reaction, a problem not found in the other COX-2s. This skin condition is what led the FDA to “request” that Pfizer pull the drug last week. Earlier, Pfizer was asked to add additional safety warnings to Bextra’s labeling, a move that fell short of a withdrawal request.
Reactions ran the gamut from shock and disbelief to “I told you so”; perhaps the most telling appeared in the New York Times:
Thalia Segal, a pain specialist at New York University, said, “We used to just put people on these drugs for life and not think about it, but we can no longer commit them to lifelong therapy with impunity. We have to use these medications judiciously and follow people more closely. We have to rely on a much more individualized approach” (O’Connor, New York Times, 4/8).
It is becoming painfully (no pun intended) obvious that the “side effects” of various medications can not only be quite serious, to the point where people die or suffer debilitating conditions, but also have been under-considered by administrators and big pharma alike. And, the treatment expense and other liability associated with these side effects will contribute to our rising health care costs. Over the short term, financial results of the pharmas will suffer (“Pfizer, which on Wednesday announced plans to reduce costs by $4 billion annually and restated 2005 earnings estimates, might have to make additional cost reductions to return to double-digit earnings growth by 2006
