Salix Pharmaceuticals Acquires Patent–Protected Metoclopramide–Zydis®
Zydis® Technology Provides Fast–Dissolving, Patient–Friendly Formulation
RALEIGH, NC, September 5, 2007 – Salix Pharmaceuticals, Ltd. (NASDAQ:SLXP) today announced that Wilmington Pharmaceuticals has granted Salix the exclusive, worldwide right to metoclopramide–Zydis®. Metoclopramide is indicated for short–term (4–12 weeks) therapy for adults with symptomatic documented
gastroesphageal reflux who fail to respond to conventional therapy and for the relief of symptoms associated with acute and recurrent diabetic gastric
stasis. Wilmington Pharmaceuticals plans to file a New Drug Application for their Zydis formulation of metoclopramide with the U.S. Food and Drug
Administration during the fourth quarter of 2007. The product has patent protection until 2022, and additional patent protection pending that, if issued, will provide patent protection until 2025. Salix is required to make a small up–front payment to Wilmington, a regulatory milestone payment to Wilmington upon NDA approval and to pay royalties to Wilmington on net sales. Additionally, Salix has entered into a separate agreement with
Catalent Pharma Solutions to supply the product. Catalent's Zydis® technology is a unique, freeze–dried oral solid dosage form
that disintegrates rapidly on the tongue and can be taken without water.
"Salix is expanding its product portfolio with the acquisition of a fast–dissolving formulation of metoclopramide," stated Carolyn Logan, President
and Chief Executive Officer, Salix. "Market research indicates a high level of demand for a patient–friendly formulation of this widely–prescribed
agent. We believe the availability of metoclopromide–Zydis® should serve to increase patient compliance and, in
many instances, provide an economical alternative to emergency room visits and/or intravenous infusion by patients suffering from nausea and gastric
distress."
Commenting on the agreement, Eugene Haley, Chief Executive Officer, Wilmington Pharmaceuticals, stated, "We are very pleased with the opportunity to have
Salix commercialize metoclopramide–Zydis®. Much like Salix, we pride ourselves in our specialized strategy to create value while avoiding the cost and risk associated with much larger and less–focused pharmaceutical product development. We are confident that Salix will
dedicate the marketing and sales expertise necessary to optimize the commercial potential of metoclopramide–Zydis®."
Wilmington Pharmaceuticals, LLC creates valuable new medicines while avoiding the large development and support staff of traditional pharmaceutical companies.
Their efforts bring patient–friendly drug delivery technologies to well–established drug products that are only available in less
than optimal dosage forms.
Catalent Pharma Solutions, headquartered in Somerset, NJ, is the world leader in providing advanced dosage form delivery technologies. Catalent's Zydis®
is the fastest dissolving oral tablet in the world. Zydis® is a unique, freeze–dried oral solid dosage form that can be swallowed without water, because it dissolves rapidly on the tongue in less than three seconds. Zydis® offers the potential
for added patient and consumer convenience, enhanced drug performance and improved patient compliance.

APRISO™ is a locally-acting aminosalicylate indicated for the maintenance of remission of ulcerative colitis in patients 18 years and older.
APRISO is contraindicated in patients with hypersensitivity to salicylates, aminosalicylates, or to any of the components of APRISO capsules.
The recommended dose of APRISO is four 0.375 g capsules once daily in the morning (1.5 g/day) with or without food. Because dissolution of the coating of APRISO
granules depends on pH, APRISO should not be coadministered with antacids. Patients with phenylketonuria should be aware that APRISO contains aspartame,
equivalent to 0.56 mg of phenylalanine. In two well-controlled clinical trials, the most common treatment-related adverse events occurring in at least 3%
of adult patients taking 1.5 g/day of APRISO were headache (11% vs. 8% for placebo), diarrhea (8% vs. 7% for placebo), upper abdominal pain (5% vs 3% for placebo),
nausea (4% vs 3% for placebo), nasopharyngitis (4% vs 3% for placebo), influenza and influenza-like illness (4% vs 4% for placebo) and sinusitis (3% vs 3% for placebo).

MoviPrep® (PEG-3350, sodium sulfate, sodium chloride, potassium chloride, sodium ascorbate and ascorbic acid for oral solution) is indicated for cleansing of the
colon as a preparation for colonoscopy in adults 18 years of age or older. MoviPrep is contraindicated in patients who have had a severe hypersensitivity reaction
to any of its components. MoviPrep should be used with caution in patients using concomitant medications that increase the risk of electrolyte abnormalities, in patients with known or suspected hyponatremia,
severe ulcerative colitis, ileus, gastrointestinal obstruction or perforation, gastric retention, toxic colitis, toxic megacolon, or glucose-6-phosphate dehydrogenase deficiency. In clinical trials, abdominal
distention, anal discomfort, thirst, nausea, and abdominal pain were the most common adverse reactions to MoviPrep administration. MoviPrep contains a maximum of 2.33 mg of phenylalanine per treatment.

Important Safety Information about OsmoPrep
There have been rare, but serious reports of acute phosphate nephropathy in patients who received oral sodium phosphate products for colon cleansing prior
to colonoscopy. Some cases have resulted in permanent impairment of renal function and some patients required long–term dialysis. While some
cases have occurred in patients without identifiable risk factors, patients at increased risk of acute phosphate nephropathy may include those with
increased age, hypovolemia, increased bowel transit time (such as bowel obstruction), active colitis, or baseline kidney disease, and those using
medicines that affect renal perfusion or function (such as diuretics, angiotensin converting enzyme [ACE] inhibitors, angiotensin receptor blockers
[ARBs], and possibly nonsteroidal anti–inflammatory drugs [NSAIDs]).
It is important to use the dose and dosing regimen as recommended (PM/AM split dose).
Please see accompanying brief summary of Prescribing Information for OsmoPrep, including
BOXED WARNINGS.
OsmoPrep® (sodium phosphate monobasic monohydrate, USP, and sodium phosphate dibasic anhydrous, USP) Tablets are indicated for cleansing
of the colon as a preparation for colonoscopy in adults 18 years of age or older. Considerable caution should be advised before OsmoPrep is used in
patients with severe renal insufficiency, congestive heart failure, ascites, unstable angina, gastric retention, ileus, severe chronic constipation,
bowel perforation, toxic megacolon, gastric bypass or stapling surgery, or hypomotility syndrome. Use with caution in patients with impaired renal
function, patients with a history of seizures or at higher risk of seizure, patients with higher risk of cardiac arrhythmias, known or suspected electrolyte
disturbances (such as dehydration), or people taking drugs that affect electrolyte levels. Patients with electrolyte abnormalities such as
hypernatremia, hyperphosphatemia, hypokalemia, or hypocalcemia should have their electrolytes corrected before treatment with OsmoPrep.
OsmoPrep is contraindicated in patients with a known allergy or hypersensitivity to sodium phosphate salts or any of its ingredients, and in patients with
biopsy–proven acute phosphate nephropathy. In clinical trials, the most commonly reported adverse reactions (reporting frequency >3%) were
abdominal bloating, nausea, abdominal pain, and vomiting. It is recommended that patients receiving OsmoPrep be advised to adequately hydrate before,
during, and after the use of OsmoPrep.

SAFETY CONSIDERATIONS
Xifaxan® (rifaximin) Tablets are indicated for the treatment of patients (≥12 years of age) with travelers’ diarrhea caused by noninvasive strains of
Escherichia coli. Xifaxan should not be used in patients with diarrhea complicated by fever or blood in the stool or diarrhea due to pathogens other than Escherichia coli. Xifaxan should be
discontinued if diarrhea symptoms get worse or persist more than 24-48 hours and alternative antibiotic therapy should be considered. Escherichia coli has been shown to develop resistance to rifaximin in vitro. However, the clinical significance of such an effect has not been studied.
In clinical trials, Xifaxan was generally well tolerated. The most common side effects (vs. placebo) were flatulence 11.3% (vs. 19.7%), headache 9.7% (vs. 9.2%), abdominal pain 7.2% (vs. 10.1%), rectal tenesmus 7.2%
(vs. 8.8%), defecation urgency 5.9% (vs. 9.2%) and nausea 5.3% (vs. 8.3%).
