H.E.L.P. IS ON THE WAY FOR PATIENTS WITH HEPATIC ENCEPHALOPATHY (HE)
Salix Pharmaceuticals Announces Launch of Patient and Provider Assistance Program to Coincide with Xifaxan550 Availability
MORRISVILLE, N.C., April 27, 2010 – Salix Pharmaceuticals, Ltd. (NASDAQ:SLXP) today announced plans for the Hepatic Encephalopathy Living Program (H.E.L.P.) (www.HELPenroll.com ). H.E.L.P. is a first–of–its–kind patient and health care provider support program for the management of hepatic encephalopathy (HE) and will launch on May 24, 2010. The program will provide patients with HE educational materials, co–pay assistance, treatment adherence support and a 24–hour toll–free hotline.
"HE patients are faced with complex treatment regimens and unpredictable episodes that can diminish quality of life," said Susan Robinson, Vice President, Programs, American Liver Foundation. "Putting support programs such as H.E.L.P. in place will give these patients access to valuable resources when they have questions or need support during even the most difficult times."
HE is a serious disorder caused by chronic liver failure that results in neurologic impairments in cognition, mental status and motor function. HE frequently occurs in patients with cirrhosis as a result of end–stage liver disease and encompasses a wide spectrum of often reversible neuropsychiatric abnormalities, including disruption in sleep patterns, changes in personality and intellectual capacity, and coma. There are reported to be approximately 200,000 patients in the United States who suffer from episodic overt HE.1,2,3
"There is an urgent need for healthcare providers, patients and their families to understand the threat posed by HE and to seek information about how to recognize its symptoms and obtain treatment," said Arun Sanyal, MD, Chairman, Division of Gastroenterology, Hepatology and Nutrition, Virginia Commonwealth University Medical Center. "Programs like H.E.L.P. may increase compliance with treatment, thereby improving outcomes for patients with HE."
H.E.L.P. will formally launch May 24, 2010, coinciding with the availability of Xifaxan550 for the reduction in risk of overt HE recurrence in patients 18 years of age or older in U.S. pharmacies. H.E.L.P. enrollment cards will be featured at the Salix Pharmaceuticals booth (#635) during Digestive Disease Week (DDW), May 1–6, 2010, in New Orleans. Physicians will be able to pre–enroll in the program, gaining access to the materials and resources provided by H.E.L.P. For more information on the H.E.L.P. program, please visit www.HELPenroll.com or call 1–866–XIFAXAN (934–2926).
The U.S. Food and Drug Administration (FDA) approved XIFAXAN® (rifaximin) 550 mg tablets for the reduction in risk of overt HE recurrence in patients 18 years of age or older on March 24, 2010. Xifaxan550 will be available for physicians and patients in the U.S. on May 24, 2010. For more information on Xifaxan550, please visit www.Xifaxan550.com .
XIFAXAN® (rifaximin) 550 mg tablets
Important Safety Information
XIFAXAN (rifaximin) 550 mg is indicated for reduction in risk of overt hepatic encephalopathy (HE) recurrence in patients ≥ 18 years of age. In the trials of XIFAXAN (rifaximin) for HE, 91% of the patients were using lactulose concomitantly. XIFAXAN (rifaximin) has not been studied in patients with MELD scores > 25, and only 8.6% of patients in the controlled trial had MELD scores over 19. There is increased systemic exposure in patients with more severe hepatic dysfunction. Therefore, caution should be exercised when administering XIFAXAN (rifaximin) to patients with severe hepatic impairment (Child–Pugh C).
XIFAXAN (rifaximin) is contraindicated in patients with a hypersensitivity to rifaximin, any of the rifamycin antimicrobial agents, or any of the components in XIFAXAN (rifaximin). Hypersensitivity reactions have included exfoliative dermatitis, angioneurotic edema, and anaphylaxis.
Clostridium difficile–associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including XIFAXAN (rifaximin), and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon which may lead to overgrowth of C. difficile. If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. The most common adverse reactions occurring in >8% of patients in the clinical study were edema peripheral (15%), nausea (14%), dizziness (13%), fatigue (12%), ascites (11%), muscle spasms (9%), pruritus (9%), and abdominal pain (9%).
About XIFAXAN® (rifaximin)
Rifaximin is a gut–selective antibiotic with negligible systemic absorption and broad–spectrum activity in vitro against both gram–positive and gram–negative pathogens. Rifaximin has a similar tolerability profile to that of placebo.
Rifaximin tablets 200 mg, which Salix markets in the United States under the trade name XIFAXAN® (rifaximin) tablets 200 mg, currently is approved for the treatment of patients, 12 years of age or older, with travelers' diarrhea (TD) caused by non–invasive strains of Escherichia coli. XIFAXAN (rifaximin) 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 (rifaximin) should be discontinued if diarrhea symptoms get worse or persist more than 24–48 hours, and alternative antibiotic therapy should be considered. In clinical trials, XIFAXAN (rifaximin) was generally well–tolerated. The most common side effects (vs. placebo) were flatulence 11.3 percent (versus 19.7 percent), headache 9.7 percent (versus 9.2 percent), abdominal pain 7.2 percent (versus 10.1 percent) and rectal tenesmus 7.2 percent (versus 8.8 percent).
Rifaximin has been used in Italy for 24 years and is approved in 33 countries. Salix acquired rights to market rifaximin in North America from Alfa Wassermann S.p.A. in Bologna, Italy. Alfa Wassermann markets rifaximin in Italy under the trade name Normix®.
About Hepatic Encephalopathy
Hepatic encephalopathy (HE) is a disorder caused by chronic liver failure resulting in cognitive, psychiatric and motor impairments. The condition encompasses a wide spectrum of often reversible neuropsychiatric abnormalities caused by the inability of the liver to remove toxic products in the gut from most notably ammonia–producing bacteria. When toxins reach the central nervous system, this condition can result in symptoms ranging in severity from mild cerebral function deficits to coma. The disorder is characterized by disruption in sleep patterns, changes in personality and intellectual capacity, high blood ammonia levels, altered neuromuscular activity and electroencephalogram (EEG) abnormalities.

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).
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.

Important Safety Information about METOZOLV ODT
Treatment with metoclopramide can cause tardive dyskinesia, a serious movement disorder that is often irreversible.
The risk of developing tardive dyskinesia increases with the duration of treatment and the total cumulative dose.
Metoclopramide therapy should be discontinued in patients who develop signs or symptoms of tardive dyskinesia.
There is no known treatment for tardive dyskinesia. In some patients, symptoms may lessen or resolve after metoclopramide treatment is stopped.
Treatment with metoclopramide for longer than 12 weeks should be avoided in all but rare cases where therapeutic benefit is thought to outweigh the risk of developing tardive dyskinesia.
METOZOLV® ODT
(metoclopramide HCl) is indicated as short-term (4 to 12 weeks) therapy for adults with symptomatic, documented gastroesophageal
reflux disease (GERD) who fail to respond to conventional therapy and for the relief of symptoms associated with acute and
recurrent diabetic gastroparesis (diabetic gastric stasis) in adults. Therapy should not exceed 12 weeks in duration. Take on
an empty stomach up to four times daily, at least 30 minutes before eating and at bedtime.
METOZOLV ODT is contraindicated in patients with intestinal obstruction, hemorrhage, or perforation; pheochromocytoma;
known sensitivity or intolerance to metoclopramide; epilepsy; or are receiving concomitant medications with extrapyramidal reactions.
Extrapyramidal symptoms (EPS), manifested primarily as acute dystonic reactions, occur in approximately 1 in 500 patients treated with the
usual adult dosages of 30 to 40 mg/day of metoclopramide. These usually are seen during the first 24 to 48 hours of treatment with metoclopramide,
occur more frequently in pediatric patients and adult patients less than 30 years of age and are even more frequent at higher doses.
Drug-induced Parkinsonism can occur during metoclopramide therapy, more commonly within the first 6 months after beginning treatment,
but also after longer periods. Patients with a history of Parkinson’s disease should be given metoclopramide cautiously, if at all,
since such patients can experience exacerbation of Parkinsonian symptoms when taking metoclopramide.
There have been rare reports of an uncommon but potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) associated
with metoclopramide. Clinical manifestations of NMS include hyperthermia, muscle rigidity, altered consciousness, and evidence of autonomic instability.
The management of NMS should include immediate discontinuation of metoclopramide and other drugs not essential to concurrent therapy.
Depression associated with metoclopramide use has occurred in patients with and without a history of depression.
For those patients with a prior history of depression, metoclopramide should only be given if the expected benefits outweigh the potential risks.
In one study in hypertensive patients, intravenously administered metoclopramide was shown to release catecholamines; hence, caution should be exercised
when metoclopramide is used in patients with hypertension. Any rapid rise in blood pressure associated with METOZOLV ODT use should result in immediate
cessation of metoclopramide use in those patients.
Since metoclopramide produces a transient increase in plasma aldosterone, patients with cirrhosis or congestive heart failure may be at risk of developing
fluid retention and volume overload. If these side effects occur at any time in any patients during metoclopramide therapy, the drug should be discontinued.
Adverse reactions, especially those involving the nervous system, may occur after stopping the use of METOZOLV ODT.
In clinical studies, the most frequently reported adverse events (≥2% occurrence) were headache, nausea, fatigue, somnolence, and vomiting.
