Critical Therapeutics' Co-Promotion Partner, DEY, L.P., Launches U.S. Sales and Marketing of ZYFLO(R) for Asthma

Product's Sales Force Increases from 18 to 220 Representatives

LEXINGTON, Mass.--(HSMN NewsFeed)--Critical Therapeutics, Inc. (Nasdaq: CRTX ) announced today that Dey, L.P. (DEY), an affiliate of Merck KGaA in Germany, began promoting ZYFLO® (zileuton tablets), Critical Therapeutics' asthma drug, in the U.S. on April 30, 2007. The addition of the DEY sales force brings the total number of sales representatives promoting ZYFLO to approximately 220. The combined sales force is focusing primarily on respiratory specialists, such as allergists and pulmonologists, as well as certain targeted primary care physicians.

"The significant increase in the sales promotion effort behind ZYFLO should generate greater physician and patient awareness of the therapeutic benefits of our asthma treatment," said Frank Thomas, President and Chief Executive Officer of Critical Therapeutics. "At the same time, we expect ZYFLO to gain greater traction in the market as information about the product becomes widely available. The combined sales effort should allow us to reach a significant base of physicians who treat asthma patients."

In March 2007, Critical Therapeutics and DEY entered into an agreement for the joint promotion of ZYFLO and, if approved by the FDA, the controlled-release formulation of zileuton (zileuton CR). Zileuton CR has a Prescription Drug User Fee Act (PDUFA) date of May 31, 2007. ZYFLO is the FDA-approved immediate-release formulation of zileuton, a four-times daily medication for asthma in patients 12 years of age and older. Zileuton CR is a twice-daily formulation that, upon FDA approval, will be marketed for asthma patients 12 years of age and older. Zileuton CR uses SkyePharma PLC's proprietary Geomatrix® drug delivery technology, which controls the amount, timing and location of drug released into the body.

About ZYFLO and Zileuton

ZYFLO® (zileuton tablets) is indicated for the prevention and chronic treatment of asthma in adults and children 12 years of age and older. Zileuton inhibits 5-lipoxygenase (5-LO), an enzyme that catalyzes the formation of leukotrienes from arachidonic acid. 5-LO is the main enzyme responsible for the production of leukotrienes, a family of inflammatory mediators that can trigger asthma symptoms, including inflammation, swelling, bronchoconstriction and mucus secretion. ZYFLO is the only 5-LO inhibitor approved for marketing by the U.S. Food and Drug Administration. ZYFLO is not indicated for use in the reversal of bronchospasm in acute asthma attacks, including status asthmaticus. Mild to moderate side effects associated with the use of ZYFLO are abdominal pain, upset stomach and nausea. A small percentage of patients treated with ZYFLO show an increased release of a liver enzyme known as ALT. As a result, the level of liver enzymes in patients treated with ZYFLO should be measured by a simple blood test. It is recommended that physicians perform this test before administering ZYFLO and repeat the test on a regular basis while patients are on the medication. ZYFLO is contraindicated in patients with active liver disease or transaminase elevations greater than or equal to three times the upper limit of normal.
