SALIX RECEIVES PURPORTED NOTICE OF PARAGRAPH IV

CERTIFICATION AGAINST PATENT FOR MOVIPREP^®

RALEIGH, NC, April 9, 2008—Salix Pharmaceuticals, Ltd. (NASDAQ:SLXP) today announced that the Company and its licensor, Norgine B.V., have received a purported notice of Paragraph IV Certification on behalf of Novel Laboratories, Inc. advising of the submission of an Abbreviated New Drug Application (ANDA) for MOVIPREP^® (PEG 3350, sodium sulfate, sodium chloride, potassium chloride, sodium ascorbate and ascorbic acid for oral solution). Novel is a privately-held company that has been affiliated with Elite Pharmaceuticals, Inc. (AMEX:ELI).

Novel’s letter alleges that U.S. Patent No. 7,169,381, owned by Norgine Europe B.V. and listed in the Orange Book for MOVIPREP, is invalid, unenforceable and/or will not be infringed by Novel’s manufacture, use or sale of the product for which the ANDA is submitted. The expiration date for U.S. Patent No. 7,169,381 is September 1, 2024.

Salix has 45 days to commence a patent infringement lawsuit against Novel that would automatically stay, or bar, the U.S. Food and Drug Administration (FDA) from approving Novel’s ANDA for up to 30 months or until a district court decision that is adverse to Salix, whichever may occur earlier.

Salix and Norgine have full confidence in the intellectual property rights that protect MOVIPREP. Moreover, Salix and Norgine intend to use all reasonable means at their disposal to vigorously defend MOVIPREP from any and all generic intrusion.

Norgine B.V., headquartered in Amsterdam, The Netherlands, is a privately-owned, European specialty pharmaceutical company, developing and marketing pharmaceutical products in the therapeutic areas of gastroenterology, hepatology and pain management. Norgine is a leader in this sector in Europe and is unique in having a balanced sales presence across all major markets. The company has over 1,000 employees and sales in 2007 were approximately $350 million.

Salix Pharmaceuticals, Ltd., headquartered in Raleigh, North Carolina, develops and markets prescription pharmaceutical products for the treatment of gastrointestinal diseases. Salix’s strategy is to in-license late-stage or marketed proprietary therapeutic drugs, complete any required development and regulatory submission of these products, and market them through the Company’s gastroenterology specialty sales and marketing team.

Salix trades on the NASDAQ Global Select Market under the ticker symbol “SLXP.”
