MISSISSAUGA, Ontario, Feb. 10, 2011 /PRNewswire/ -- Valeant Pharmaceuticals International, Inc. (NYSE: VRX) (TSX: VRX) today announced that its subsidiary, Biovail Laboratories International SRL (BLS), has acquired the Canadian rights to Cholestagel® (colesevelam), an oral bile acid sequestrant for hypercholesterolemia, from Genzyme Corporation ("Genzyme"). Genzyme will receive from BLS a $2 million upfront payment, to be followed by subsequent additional milestone payments totaling up to $7 million.

"Cholestagel® is a strong addition to our Canadian franchise," said J. Michael Pearson, chief executive officer. "While this compound is currently pending marketing approval from Health Canada, the use of Cholestagel® has been shown to be effective as an adjunctive option in the treatment of high levels of cholesterol in the blood in the countries where it is currently marketed. This product will be promoted by our existing sales force in Canada and will be a complementary fit with our existing Tiazac® XC promotions."

About Cholestagel® (colesevelam)

Colesevelam is a bile acid sequestrant administered orally. It is developed by Genzyme and marketed in the U.S. by Daiichi Sankyo under the brand name WelChol and elsewhere by Genzyme under the tradename Cholestagel®. Colesevelam is indicated as an adjunct to diet and exercise to reduce elevated low-density lipoprotein cholesterol (LDL-C) in patients with primary hyperlipidemia as monotherapy and combination therapy with a statin.

Unlike most other cholesterol-lowering agents, colesevelam is non-systemic, and therefore is not absorbed into the bloodstream. Colesevelam binds bile acids in the intestine, impeding their reabsorption. This process – called bile acid sequestration – results in an increased clearance of LDL-C from the blood. Colesevelam is also well-tolerated, with minimal gastrointestinal side effects similar to those seen with placebo, and has limited drug interactions.

Important Safety Information

In clinical trials with Cholestagel® (colesevelam), the most common (incidence > 2% and greater than placebo) adverse reactions with Cholestagel® included constipation, dyspepsia, and nausea. In the diabetes trials, the overall incidence of hypoglycemia was 3.0% in Cholestagel® – treated patients and 2.3% in placebo-treated patients.

Post-marketing ADR (adverse drug reactions) reports include bowel obstruction, dysphagia, esophageal obstruction, fecal impaction, hypertriglyceridemia, pancreatitis and increased transaminases. Additionally some interaction reports were received describing changes in phenytoin levels, reduced International Normalized Ratio (INR), and elevated thyroid-stimulating hormone (TSH). However, because these reactions are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Cholestagel® is contraindicated in patients who are hypersensitive to this drug or to any ingredient in the formulation or component of the container. Cholestagel® is contraindicated in patients with bowel or biliary obstruction. Cholestagel® is contraindicated in patients with serum triglyceride (TG) > 500 mg/dL and in patients with a history of hypertiglyceridemia-induced pancreatitis.
