TEANECK, N.J., and TITUSVILLE, N.J., Nov. 14 /PRNewswire/ -- Aciphex, a
proton pump inhibitor (PPI) widely prescribed for gastroesophageal reflux
disease (GERD), is now approved by the Food and Drug Administration as part of
the first seven-day treatment for Helicobacter pylori (H. pylori) infection,
the single most common cause of peptic ulcers. Taken in combination with
certain antibiotics, Aciphex offers a faster therapy option than other PPIs,
treating H. pylori in up to half the time of current 10 to 14 day treatments.
When used in combination with amoxicillin and clarithromycin as a
three-drug regimen, Aciphex is indicated for the treatment of patients with H.
pylori infection and duodenal ulcer disease (active or history within the last
five years) to eradicate H. pylori.
Up to 60 million American adults are currently infected with H. pylori (a
type of bacteria in the stomach); as many as one in 10 Americans will develop
an ulcer in their lifetime.
"Using Aciphex, plus antibiotics for one week to eradicate H. pylori is a
faster treatment option than what is currently available," said Nimish Vakil,
M.D., Clinical Professor of Medicine at the University of Wisconsin Medical
School (Milwaukee, Wis.). "When you consider the fact that the majority of
duodenal and gastric ulcers are caused by H. pylori infection and that a short
treatment course eradicates the infection and prevents relapse, you can
understand the importance of this infection in ulcer disease."
A multicenter, double-blind, placebo-controlled trial was conducted in
803 patients infected with H. pylori at 47 centers nationwide. In the study,
84 percent of patients treated with Aciphex(R) (rabeprazole sodium),
amoxicillin and clarithromycin taken twice daily were free of H. pylori after
seven days of therapy. Eighty-six percent of patients taking the identical
regimen achieved the same result after 10 days of treatment, with no
significant difference obtained with three additional days of therapy. H.
pylori was eradicated in 82 percent of patients treated with a combination of
omeprazole, amoxicillin and clarithromycin taken twice daily for 10 days based
on per protocol analysis. The three-day Aciphex, amoxicillin and
clarithromycin treatment arm was clinically sub-optimal for H. pylori
eradication. Eradication of bacteria was determined by a negative Urea Breath
Test (13C-UBT) at 42 or more days after the end of therapy.
In clinical trials using combination therapy with rabeprazole plus
amoxicillin and clarithromycin (RAC), no adverse events unique to this drug
combination were observed. In the U.S. multicenter study, the most frequently
reported drug related adverse events for patients who received RAC therapy for
seven or 10 days were diarrhea (8 percent and 7 percent) and taste perversion
(6 percent and 10 percent) respectively.
No clinically significant laboratory abnormalities particular to the drug
combinations were observed.

amoxicillin or clarithromycin, refer to their respective package prescribing
Clarithromycin is contraindicated in patients taking cisapride or
pimozide; or in patients with a known hypersensitivity to clarithromycin or
any macrolide antibiotic. Clarithromycin may elevate digoxin serum
concentrations. Serum digoxin levels should be carefully monitored while
digoxin and clarithromycin are taken concomitantly. Clarithromycin should not
be used in pregnant women except in circumstances where no alternative therapy
is appropriate. Amoxicillin is contraindicated in patients who are allergic
to any penicillin.
About Aciphex(R)(rabeprazole sodium)
Aciphex is also indicated for the treatment of symptomatic GERD, healing
of erosive GERD, maintenance of healed erosive GERD, healing of duodenal
ulcers and treatment of symptoms related to these conditions. In addition,
Aciphex is approved for the treatment of pathological hypersecretory
conditions, including Zollinger-Ellison syndrome, a rare disorder that causes
the stomach to produce excess acid.
Aciphex has a well-established safety record. In studies, the most common
side effect possibly related to Aciphex was headache (2.4 percent vs
1.6 percent for sugar pill). Aciphex should not be used if you have had an
allergic reaction to Aciphex, its tablet ingredients, or any proton pump
inhibitor (PPI). Reduction in symptoms during treatment with Aciphex does not
rule out the presence of gastric malignancy. Patients treated with a PPI,
like Aciphex, and warfarin (such as Coumadin(R)(1)) may need to be monitored
more closely by their doctor.
