CELEBREX
Pharmacia/Pfizer's hailed breakthrough painkiller, Celebrex, launched
in January 1999 as a pain relief drug for arthritis. Celebrex immediately
overtook the previous Viagra record of highest number of scripts issued
within the first 15 weeks with 3.2 million. But millions of prescriptions
filled, and just three months on the market, reports linking Celebrex
to 10 deaths and 11 cases of gastrointestinal hemorrhages surfaced,
according to the FDA, leaving many concerned over the safety of the
deemed "super aspirin".
April 6, 2000, the FDA wrote a letter concerned with Pharmacia's Celebrex
and its promotional advertisements that misrepresented the safety of
the drug. This letter came despite the prior FDA warning regarding the
same advertisements. Cardiovascular problems, as well as kidney and
liver damage, ulcers, and even death, have been linked to this controversial
drug. The FDA stated its concern over the misrepresentation of safety
information, the unsubstantiated comparative claims, the lack of fair
balance, and the misrepresentation of efficacy information.
The annual rates of heart attack in both the Celebrex (celecoxib) and
Vioxx (rofecoxib) studies were increased compared to a review of studies
containing a total of more than 48,000 patients. In those studies, 0.52%
of patients taking an inactive placebo pill had a heart attack each
year. The annual rate of heart attack was 0.74% for patients taking
rofecoxib and 0.80% for those taking celecoxib. The researches believe
that until more research is done, doctors should use caution in prescribing
Vioxx and Celebrex to patients with heart disease.
