About Pfizer
Pfizer, one of the largest pharmaceutical companies in the
world, has enjoyed an annual revenue of almost three billion
dollars from Celebrex sales in the US since this prescription
painkiller was d its ads for the pain reliever
The Food and Drug Administration (FDA) announced in December
2004 important new information on side effects associated with
the use of Bextra, a COX-2 selective non-steroidal
anti-inflammatory drug (NSAID) which is indicated for the
treatment of osteoarthritis, rheumatoid arthritis and
dysmenorrhea (menstrual pain). A "boxed" warning, strengthening
previous warnings about the risk of life-threatening skin
reactions and a new bolded warning contraindicating the use of
Bextra in patients undergoing coronary artery bypass graft (CABG)
surgery will be added to the label
BEXTRA SIDE EFFECTS
The new boxed warning in the label states that patients taking
Bextra have reported serious, potentially fatal skin reactions,
including Steven-Johnson Syndrome and toxic epidermal necrolysis.
These skin reactions are most likely to occur in the first 2
weeks of treatment, but can occur any time during therapy. In a
few cases, these reactions have resulted in death.
As of November 2004, FDA had received reports of a total of 87
cases in the United States of severe skin reactions in
association with Bextra, including Stevens-Johnson Syndrome and
toxic epidermal necrolysis. Twenty of the 87 cases involved
patients with a known allergy to sulfa. Of these 87 cases, 36
hospitalizations were reported, including 4 deaths. Other Cox-2
selective inhibitors and traditional NSAIDs such as naproxen and
ibuprofen also have a risk for these rare, serious skin
reactions, but the reported rate of these serious side effects
appears to be greater for Bextra than for other COX-2 agents
In addition to highlighting serious skin reactions, the
strengthened label warnings also highlight new data about
cardiovascular risks. A recently-completed study conducted by
Pfizer, which included over 1,500 patients treated after CABG,
showed an increased cardiovascular risk in patients treated with
Bextra compared to placebo. Observed cardiovascular events
included thromboembolic events such as myocardial infarction
(heart attack), cerebrovascular accident (stroke), deep vein
thrombosis (blood clots in the leg), and pulmonary embolism
(blood clot in the lung).
Pfizer submitted the final report of the new CABG study to FDA
on November 5, 2004. The report confirms the risk of the
intravenous form (about 2 percent of patients had such an
adverse event) and also shows that oral Bextra is associated
with a lower, but some, risk (about 1 percent of patients)
immediately following CABG surgery--a very specific medical
setting. In the placebo group, about 0.5 percent of patients had
an adverse cardiovascular event. Bextra is not approved for use
in the treatment of postoperative pain of any type; however, FDA
believes that these new findings should be made available to
healthcare professionals and patients, and the bolded warning
specifically contraindicates Bextra for treatment of pain
immediately following CABG.
BEXTRA CLASS ACTION LAWSUIT
Pfizer is the target of a class action lawsuit filed November
12, 2004 alleging the company violated the Illinois Consumer
Fraud and Deceptive Business Practices Act. The suit is seeking
up to $75,000 per class member with allegations that Pfizer
failed to provide proper warning about its arthritis drug Bextra
to doctors and consumers in package inserts and reference
manuals for doctors. Barbara Mihalich filed the Bextra class
action lawsuit.
BEXTRA RECALL
Bextra was removed from the market on April 7, 2005 at the
request of the FDA. The FDA cited inadequate information on
possible heart risks from long-term use of the drug as well as
life-threatening skin reactions, including deaths. The
regulatory agency also called for the strongest warning possible
on Pfizer's other arthritis product, Celebrex.
