Colazal(R) Pediatric Indication Approved

First 5-ASA Approved for Pediatric Use in Ulcerative Colitis

RALEIGH, N.C.--(HSMN NewsFeed)--Salix Pharmaceuticals, Ltd. (NASDAQ:SLXP ) today announced that the U.S. Food and Drug Administration (FDA) has granted approval of the use of COLAZAL® (balsalazide disodium) Capsules 750 mg in pediatric patients between 5 to 17 years of age with ulcerative colitis. COLAZAL is an anti-inflammatory drug approved for the treatment of mildly to moderately active ulcerative colitis.

Commenting on the approval, Carolyn Logan, President and Chief Executive Officer, stated, "This label expansion sets COLAZAL apart from all other 5-aminosalicyclic acid, or 5-ASA, products used to treat ulcerative colitis and makes COLAZAL the only 5-ASA approved for use in pediatric patients. We believe this approval speaks, in large part, to the tolerability of our unique, azo-bonded prodrug formulation of 5-ASA, which is specifically designed for 99% delivery of 5-ASA directly to the colon. We also believe that this approval again demonstrates the Company's commitment to bring gastroenterologists the products needed to provide for all of their patients. This approval, combined with the September labeling approval which provides for the administration of COLAZAL as sprinkled over applesauce, should provide gastroenterologists with an option that increases their level of comfort and confidence in treating children."
