Salix Pharmaceuticals, Ltd. (NASDAQ:SLXP) today announced that five presentations describing the investigation of methylnaltrexone bromide as a potential treatment for opioid-induced constipation in adult patients with chronic, non-cancer pain will occur during The National Conference on Pain for Frontline Practitioners, or “PAINWeek”. PAINWeek is being held in Las Vegas, NV, Wednesday, Sept. 5 – Saturday, Sept. 8. RELISTOR ® (methylnaltrexone bromide) injection for subcutaneous use Rauck et al. “Cardiac Safety of Subcutaneous Methylnaltrexone: Results from a Pooled Safety Analysis and a Case-Controlled Analysis in Noncancer Pain Patients with Opioid-Induced Constipation” Methylnaltrexone bromide for oral use Pepin et al. “Efficacy and Safety of Daily and As Needed Dosing of Oral Methylnaltrexone for the Treatment of Opioid-Induced Constipation in Patients with Chronic Noncancer Pain” Rauck et al. “Cardiac Safety of Oral Methylnaltrexone in Healthy Subjects and Noncancer Pain Patients with Opioid-Induced Constipation” Rauck et al. “Oral Methylnaltrexone for the Treatment of Opioid-Induced Constipation in Patients with Noncancer Pain” Slatkin et al. “Safety and Tolerability of Oral Methylnaltrexone in Chronic Noncancer Pain Patients with Opioid-Induced Constipation” About RELISTOR (methylnaltrexone bromide), Opioids and Constipation Opioid analgesics are frequently prescribed for patients with chronic pain. Constipation, a common side effect, occurs in patients receiving opioid therapy. RELISTOR is the first approved medication that specifically targets the underlying cause of opioid-induced constipation in advanced illness patients when laxatives are insufficient. Opioids relieve pain by specifically interacting with mu–opioid receptors within the brain and spinal cord. However, opioids also interact with mu–opioid receptors found outside the central nervous system, such as those within the gastrointestinal tract, resulting in constipation that can be debilitating. RELISTOR is a peripherally acting mu–opioid receptor antagonist that does not cross the blood-brain barrier and was specifically designed to block mu-opioid receptors in the GI tract, therefore decreasing the constipating effects of opioid pain medications without affecting their ability to relieve pain.
RELISTOR Subcutaneous Injection was approved in the United States in 2008 for the treatment of opioid-induced constipation in patients with advanced illness who are receiving palliative care, when response to laxative therapy has not been sufficient. The use of RELISTOR beyond four months has not been studied. The drug is also approved for use in 58 countries worldwide, including the European Union, Canada and Australia. In the 27 member states of the E.U., as well as Iceland, Norway and Liechtenstein, RELISTOR is approved for the treatment of opioid–induced constipation in advanced illness patients who are receiving palliative care when response to usual laxative therapy has not been sufficient. In Canada, the drug is approved for the treatment of opioid–induced constipation in patients with advanced illness, receiving palliative care. When response to laxatives has been insufficient, RELISTOR should be used as an adjunct therapy to induce a prompt bowel movement. Applications in additional countries are pending. RELISTOR is under exclusive license to Salix Pharmaceuticals worldwide except Japan, and to Ono Pharmaceutical in Japan only, from Progenics Pharmaceuticals. Salix is developing both subcutaneous injection and oral formulations of methylnaltrexone bromide for the potential treatment of opioid-induced constipation in adult patients with chronic, non-cancer pain.For more information about RELISTOR, please visit www.RELISTOR.com. Important Safety Information for RELISTOR RELISTOR is indicated for the treatment of opioid–induced constipation in patients with advanced illness who are receiving palliative care, when response to laxative therapy has not been sufficient.

If severe or persistent diarrhea occurs during treatment, advise patients to discontinue therapy with RELISTOR and consult their physician. Use of RELISTOR has not been studied in patients with peritoneal catheters. Safety and efficacy of RELISTOR have not been established in pediatric patients.
Rare cases of gastrointestinal (GI) perforation have been reported in advanced illness patients with conditions that may be associated with localized or diffuse reduction of structural integrity in the wall of the GI tract (i.e., cancer, peptic ulcer, Ogilvie's syndrome). Perforations have involved varying regions of the GI tract (e.g., stomach, duodenum, colon).Use RELISTOR with caution in patients with known or suspected lesions of the GI tract. Advise patients to discontinue therapy with RELISTOR and promptly notify their physician if they develop severe, persistent, and/or worsening abdominal symptoms. The most common adverse reactions reported with RELISTOR compared with placebo in clinical trials were abdominal pain (28.5% vs 9.8%), flatulence (13.3% vs 5.7%), nausea (11.5% vs 4.9%), dizziness (7.3% vs 2.4%), diarrhea (5.5% vs 2.4%), and hyperhidrosis (6.7% vs 6.5%).
