Celebrex May Up Blood Pressure
Study Shows Advil and Aleve Associated With Higher Rate of
Hypertension
By Charlene Laino
New York City -- The popular antiarthritis drug Celebrex appears to
raise blood pressure, but the effect is not as large as that associated
with the use of some other painkillers such as Advil or Aleve, according
to a study of over 44,000 people.
"Hypertension was more prevalent in patients given Celebrex than
those given placebo, which didn’t raise blood pressure at all,” says
researcher William B. White, MD, of the University of Connecticut School
of Medicine in Farmington.
But when Celebrex, a so-called Cox-2 drug, was compared with other
types of nonsteroidal anti-inflammatory pain relievers, called NSAIDs,
“the other NSAIDS raised blood pressure more,” he tells WebMD.
The findings were presented at the American Society of Hypertension
meeting here.
Controversy Over Cox-2 Drugs
The Cox-2 drugs have been a cause of concern since one such drug,
Vioxx, was voluntarily removed from the market in September 2004 due to
an increased risk of heart attacks among people who took the drug daily
for more than 18 months. Then another drug, Bextra, was pulled from the
U.S. market after the FDA said its risks of heart, stomach, and skin
problems outweighed its benefits.
That left Celebrex as the only Cox-2 drug on the market. But even it
was forced by the FDA to carry strict new warnings alerting doctors and
patients that it elevates the risk of heart attacks and strokes.
Meanwhile, other studies showed that other NSAIDS, such as Advil and
Aleve, also increase the risk of heart attacks in people with arthritis.
So doctors have been urging all involved to weigh their individual risks
when choosing a painkiller.
Due to the controversy surrounding the use of Celebrex and other
NSAIDs, White’s study, which was originally scheduled to be featured in
a news conference here, was removed from its agenda. After his
presentation to other doctors, which reporters were allowed to attend,
White told WebMD that the American Society of Hypertensions simply told
him the issue was controversial and to avoid the press room.
Celebrex vs. Other NSAIDs
The new study was an analysis of 41 trials comparing Celebrex either
to other NSAIDs or placebo for disorders ranging from osteoarthritis to
Alzheimer's disease.
Of the total, 24,933 patients received Celebrex at doses ranging from
50 milligrams to 800 milligrams a day; 13,990 received the NSAIDS Aleve,
Advil, Voltaren, Orudis, or Loxonin, and 4,057 received a placebo.
In the studies comparing Celebrex to placebo, 1.1% of people taking
Celebrex developed high blood pressure compared with 0.7% of placebo
patients. Also, 0.2% of people on Celebrex developed heart failure vs.
less than 0.1% on placebo.
But in the studies comparing Celebrex to the other NSAIDs, just 1.5%
of those on Celebrex developed hypertension compared with 2% on NSAIDs.
The risk of heart failure was 0.1% in the Celebrex group and 0.2% in the
NSAID group.
White says that the dose of Celebrex did not affect the results.
“While Celebrex at all doses yielded a higher rate of high blood
pressure than placebo, it was still very low,” he says.
Billy Arant Jr., MD, of the University of Tennessee College of
Medicine in Chattanooga, says the study provides important new
information for doctors to share with their patients when weighing the
risks and benefits of using the popular painkillers.
“It is data that were not available on such a large scale until this
point,” he tells WebMD. |
