Reports
Indicate Bextra More Than Doubles the Risk of Heart Attack
and Stroke in Clinical Studies
On January 17, 2005, the American
Heart Association published results of a study that found
some Pfizer patients were at a threefold risk of suffering
a heart attack or stroke. The warning brought further attention
to Bextra and the entire class of Cox-2 drugs whose safety
has been called into question following the Vioxx
recall.
Bextra is a COX-2 inhibitor
prescribed to treat those suffering from osteoarthritis, rheumatoid
arthritis, and menstrual cramping. The drug is manufactured
by Pfizer, Inc.
The report from the American
Heart Association corroborated a study reported on November
10, 2004 in the New York Times. That safety study established
a linked between Bextra and serious cardiovascular side
effects, including heart attack and stroke.
The release of these studies
comes on the heels of the Vioxx
recall. Vioxx is another arthritis drug in the same family
of medications as Bextra. Medical experts speculate that the
problems associated with Vioxx likely affect other Cox-2 inhibitors,
including Bextra. Doctors are warning physicians to reevaluate
use of Bextra and the other Cox-2 drugs. O'Steen & Harrison
also is representing people injured by Vioxx
and Celebrex.
The study reported in the New
York Times linked Bextra with increased incidences of heart
attack and stroke after analyzing data from 5,930 patients
participating in 12 separate clinical trials.
Garret Fitzgerald, a cardiologist
at the University of Pennsylvania, briefed the American Heart
Association on the dangers of Bextra. Dr. Fitzgerald speculated
that Bextra may be even more dangerous than Vioxx,
a competing drug.
Patients taking Bextra reportedly
suffered 2.19 times more heart attacks and strokes than those
patients who were given a placebo. Speaking before Congress,
Dr. Graham of the FDA testified that he was concerned with
the safety warnings regarding Bextra and was unsure the FDA
was in a position to protect Americans against the dangerous
Bextra side effects.
