Toronto Stock Exchange Symbol: DND

MISSISSAUGA, ON, March 26 /CNW/ - Cipher Pharmaceuticals Inc. (TSX: DND) today announced that its New Drug Submission (NDS) to Health Canada for CIP-TRAMADOL ER, its extended-release formulation of tramadol, has been accepted for review. The Company expects the review to be completed by early 2011.

"The Canadian market for tramadol is strong and growing, with sales of approximately $50 million last year, a 30 per cent increase over the prior year," said Larry Andrews, President and CEO of Cipher. "With a fast absorption profile, no food effect, and 24-hour pain coverage, we believe our product would provide an attractive treatment option for moderately severe pain. This submission is consistent with our plans to target additional markets for our three existing products."

About Cipher Pharmaceuticals Inc.

Cipher Pharmaceuticals is a commercial-stage drug development company focused on commercializing novel formulations of successful, currently marketed molecules using advanced drug delivery technologies. Cipher's strategy is to in-license products that incorporate proven drug delivery technologies and advance them through the clinical development and regulatory approval stages, after which the products are out-licensed to international partners. Because Cipher's products are based on proven technology platforms applied to currently marketed drugs, they are expected to have lower approval risk, shorter development timelines and significantly lower development costs. The Company's lead compound is being marketed in the United States by Kowa Pharmaceuticals America under the label Lipofen(R). In addition, Cipher is developing formulations of the pain reliever tramadol (tentative FDA approval in February 2009) and the acne treatment isotretinoin (FDA approvable letter in April 2007).

Cipher is listed on the Toronto Stock Exchange under the symbol 'DND' and has approximately 24 million shares outstanding. For more information, please visit www.cipherpharma.com.
