Exhibit 99.1 Critical Therapeutics Reports Financial Results for the Quarter Ended June 30, 2007 Quarter Highlighted By FDA Approval of Twice-daily ZYFLO CR(TM) Tablets LEXINGTON, Mass.--(BUSINESS WIRE)--Aug. 8, 2007--Critical Therapeutics, Inc. (Nasdaq: CRTX), a biopharmaceutical company focused on developing and commercializing innovative products for respiratory, inflammatory and critical care diseases, today reported financial results for the quarter ended June 30, 2007. During the second quarter of 2007, the U.S. Food and Drug Administration (FDA) approved twice-daily ZYFLO CR(TM) (zileuton) extended-release tablets for the prevention and chronic treatment of asthma. "During the first half of 2007, we made significant financial progress with a reduction in net cash expenditures of 72 percent from the first half of 2006," said Frank Thomas, Critical Therapeutics' president and chief executive officer. "In addition, upfront and milestone payments from our co-promotion partner, Dey, L.P. (DEY), have put us in a stronger position to fund the launch of ZYFLO CR." For the three months ended June 30, 2007, the Company posted a net loss of $13.0 million, or $0.30 per share, based on 42.6 million weighted average shares outstanding. This compares with a net loss of $14.4 million, or $0.42 per share, for the same period in 2006, based on 34.2 million weighted average shares outstanding. The increase in common shares outstanding resulted primarily from the Company's registered offering of 7.5 million shares in October 2006. Sales of the Company's immediate-release formulation of zileuton, ZYFLO(R) (zileuton tablets), in the second quarter of 2007 benefited from the co-promotion of the product by DEY, an affiliate of Merck KGaA in Darmstadt, Germany. DEY's 200-person sales force began promoting ZYFLO on April 30, 2007. For the three months ended June 30, 2007, sales of ZYFLO increased 28 percent to $2.3 million, compared with $1.8 million in the same period last year. Sales of ZYFLO in the first quarter of 2007 totaled $2.9 million and were positively impacted by a one-time net increase of $953,000 due to the Company changing the way it recognizes revenue from sales of ZYFLO. Through the end of 2006, product sales from ZYFLO were recorded when the product was dispensed through patient prescriptions rather than when the product was shipped to third parties. Beginning in the first quarter of 2007, the Company began recognizing revenue from sales of ZYFLO when the product is shipped to third-parties, less an estimate of expected product returns, resulting in the one-time adjustment of $953,000. "Since the Company's restructuring in October 2006, we executed on each of the objectives laid out at that time," Thomas continued. "This included obtaining a co-promotion partner for ZYFLO CR; securing FDA approval of ZYFLO CR; and preparing for the successful commercialization of ZYFLO CR by initiating a Phase IV clinical trial and executing on an aggressive publication strategy; and preserving cash to support the upcoming launch of ZYFLO CR. Looking ahead, we are laying the groundwork for a successful launch of ZYFLO CR this fall and will continue to focus our resources on the programs that we believe will drive shareholder value." Cash and short-term investments as of June 30, 2007 totaled $40.5 million, compared with $46.0 million at March 31, 2007 and $49.0 million at December 31, 2006. Net cash expenditures in the second quarter of 2007 were $5.5 million. As a result of the approval of ZYFLO CR by the FDA, net cash expenditures in the second quarter of 2007 were positively impacted by a $4.0 million payment received from DEY, partially offset by $3.1 million in milestone payments made to third parties. This amount compares with net cash expenditures of $12.4 million in the second quarter of 2006 and $3.1 million in the first quarter of 2007, which was positively impacted by a $3.0 million payment from DEY as a result of signing the co-promotion agreement. As of June 30, 2007, the Company had 43.2 million common shares outstanding, excluding warrants and stock options. Recent Developments Since the end of the first quarter of 2007, Critical Therapeutics has: -- Received approval from the FDA for the commercialization of ZYFLO CR in the U.S. ZYFLO CR and ZYFLO are the only FDA-approved leukotriene synthesis inhibitors for the prophylaxis and chronic treatment of asthma in adults and children 12 years of age and older. -- Added an additional 200 sales representatives promoting ZYFLO through its co-promotion agreement with DEY, thereby continuing to increase unit volume and sales of ZYFLO. -- Entered into a definitive agreement with DEY to co-promote Perforomist(TM) (formoterol fumarate) Inhalation Solution, DEY's product for Chronic Obstructive Pulmonary Disease (COPD). A second product allows Critical Therapeutics to increase the efficiency of its sales force, and a COPD product should allow its sales force better access to more pulmonologists. -- Announced the FDA approval of DEY's COPD product, Perforomist, which Critical Therapeutics will co-promote with DEY upon its expected U.S. launch in the fall of 2007. Twice-daily Perforomist is approved for the long-term maintenance treatment of bronchoconstriction for emphysema and chronic bronchitis. -- Announced the enrollment of the first patient in a Phase IV clinical trial designed to evaluate the efficacy of ZYFLO CR in asthma patients whose symptoms are poorly controlled despite taking moderate dose inhaled corticosteroids. -- Continued to execute on its publication strategy to enhance the scientific and medical understanding of the Company's commercial and development programs through a series of publications in peer-reviewed medical journals. Data from a Phase III clinical trial that was conducted primarily to assess the long-term safety of ZYFLO CR in patients on usual care asthma therapy was published in the June issue of the Journal of Asthma. The Phase III clinical trial assessing the efficacy of ZYFLO CR is expected to be published during the second half of 2007. -- Selected an alpha-7 lead development compound and initiated preclinical development activities with this lead candidate. Financial Results for the Three Months Ended June 30, 2007 and 2006 Total revenue for the three months ended June 30, 2007 was $3.4 million, compared with $3.5 million for the same period in 2006. Revenue for the second quarter of 2007 included: -- Sales of ZYFLO that accounted for $2.3 million in revenue, compared with $1.8 million in the second quarter of 2006. The 28 percent increase is primarily due to a 4 percent increase in prescription volume and an 11 percent increase in the price of ZYFLO over the second quarter of 2006. -- Collaboration and license revenue of $1.1 million from Critical Therapeutics' HMGB1 collaboration with MedImmune, Inc. and its license agreements with Beckman Coulter, Inc. to develop HMGB1 diagnostic assays and Innovative Metabolics, Inc. to develop medical device approaches to stimulating the vagus nerve. This compares with collaboration and license revenue of $1.7 million in the second quarter of 2006. The decrease is primarily associated with a decline in collaboration revenue from MedImmune, partially offset by revenue received from the Company's license agreement with Innovative Metabolics. The Company's future collaboration revenue from the MedImmune, Beckman Coulter and Innovative Metabolics agreements will primarily be recognized in periods when milestones are achieved, as all of the up-front payments under these agreements have now been fully amortized or recorded. Total operating expenses for the three months ended June 30, 2007 totaled $16.9 million, compared with $18.6 million for the same period in 2006. Total operating expenses for the second quarter of 2007 included: -- Cost of products sold that totaled $680,000, compared with $890,000 in the second quarter of 2006. The 2006 figure included inventory write-offs of $187,000 resulting from excess or obsolete inventory that could no longer be used for commercial sales. Excluding the impact of the 2006 write-off, gross margins from products sales were $1.6 million, or 70 percent, during the three months ended June 30, 2007, compared with gross margins from product sales of $1.1 million, or 61 percent, during the same period in 2006. -- Research and development (R&D) expenses that totaled $10.1 million, consisting of $6.6 million in paid and accrued milestone payments and $3.5 million of general R&D expenses. This compares with $6.9 million in R&D expenses in the same period of 2006. The increase of $3.2 million, or 46 percent, is related primarily to paid and accrued milestone payments to third parties as a result of the FDA approval of ZYFLO CR in May 2007, partially offset by a decrease in expenses associated with clinical trials and fewer employees performing R&D functions. Excluding these paid and accrued milestone payments, R&D expenses would have decreased 49 percent in the second quarter of 2007, as compared with the second quarter of 2006. -- Sales and marketing expenses that totaled $2.6 million, compared with $5.7 million in the second quarter of 2006, a decrease of $3.1 million, or 54 percent. This decrease was primarily associated with the 2006 reduction in the Company's sales force, partially offset by promotional and other marketing expenses associated with the Company's co-promotion agreement with DEY that was signed in March 2007. -- General and administrative (G&A) expenses that totaled $3.5 million, compared with $5.1 million in the second quarter of 2006, a decrease of $1.6 million, or 31 percent. This decrease was primarily associated with fewer employees performing G&A functions in 2007, as well as severance paid and stock-based compensation expense in the second quarter of 2006 in connection with the departure of the Company's former chief executive officer. Financial Results for the Six Months Ended June 30, 2007 and 2006 Total revenue for the six months ended June 30, 2007 increased $1.1 million to $6.9 million, compared with $5.8 million for the same period in 2006, an increase of 19 percent. Product sales of ZYFLO accounted for $5.2 million of revenue during the first half of 2007, compared with $2.8 million during the first half of 2006, an increase of 86 percent. Critical Therapeutics' collaboration with MedImmune and its license agreements with Beckman Coulter and Innovative Metabolics accounted for $1.7 million in revenue during the first half of 2007, compared with $2.9 million from the MedImmune and Beckman Coulter collaborations during the first half of 2006. Total operating expenses for the six months ended June 30, 2007 decreased $12.7 million to $25.6 million, compared with $38.3 million for the same period in 2006. This decrease was primarily due to a reduction in the number of employees and active R&D programs as a result of the 2006 restructurings. Research & Development Update Critical Therapeutics preclinical and development programs remain on schedule with three clinical trials planned during the second half of 2007. ZYFLO CR Phase IV Trial In July 2007, the Company initiated a Phase IV clinical trial evaluating ZYFLO CR as an add-on therapy in asthma patients to support sales and marketing efforts for ZYFLO CR. The randomized, double-blind placebo-controlled trial in 400 patients will assess the effect of ZYFLO CR on lung function, asthma control and symptomatic response in adults whose asthma is not effectively controlled with moderate doses of inhaled corticosteroids. Zileuton Injection Program The Company is developing an injectable formulation of zileuton for adjunctive use in emergency room or urgent care settings for patients experiencing acute exacerbations of asthma. The Company is on target to initiate a Phase II clinical trial in the second half of 2007 following an earlier clinical trial in asthma patients. This Phase II trial will be focused on identifying the optimal dose to be tested in Phase III clinical trials. R(+) Zileuton Program The Company is currently examining the pharmacokinetic and pharmacodynamic profile of the R isomer of zileuton to determine if there are potential dosing improvements for patients. Critical Therapeutics plans to initiate a Phase I clinical trial in the third quarter of 2007 to pursue development of the R isomer. The successful development of the R isomer could lead to an enhanced intellectual property position of zileuton for the treatment of asthma and provide for possible development opportunities in other inflammatory diseases, including COPD and nasal polyps. Alpha-7 Program The Company's alpha-7 program, which is directed at the discovery and development of novel small molecule drugs for the treatment of inflammation, has selected a lead compound that is currently in preclinical development. The Company believes that this innovative anti-inflammatory approach has the potential for broad applications in both acute and chronic inflammatory diseases and is exploring possible collaborations with larger pharmaceutical companies to leverage the broad potential of this pathway. HMGB1 Program The Company continues to collaborate with MedImmune, Inc. on the development of a human monoclonal antibody to the cytokine HMGB1. The collaboration has narrowed down potential clinical candidates to one fully-human antibody that has shown efficacy in pre-clinical models of arthritis and lupus. The joint development team expects its next step to be the selection of a clinical candidate for the development of HMGB1 antibodies for chronic inflammatory disease, such as rheumatoid arthritis or lupus. The collaboration also has narrowed the potential clinical candidates for development in acute inflammatory diseases, such as sepsis. Financial Guidance As part of the DEY co-promotion partnership, Critical Therapeutics received a $3.0 million payment upon the signing of the agreement in the first quarter of 2007 and a $4.0 million payment upon FDA approval of ZYFLO CR in the second quarter of 2007. The Company is amortizing the payments over the term of the agreement along with any future milestone payments received from DEY. The amortization of the upfront and milestone payments will offset some or all of the co-promotion fees paid to DEY for promoting ZYFLO and ZYFLO CR and will be included as a reduction to sales and marketing expenses in future periods. Critical Therapeutics will record all revenue associated with sales of ZYFLO and ZYFLO CR and pay a co-promotion fee to DEY that will be included in sales and marketing expenses. Critical Therapeutics expects net cash expenditures to be between $15 million and $17 million in the second half of 2007. For the year ending December 31, 2007, the Company expects net cash expenditures to be between $23 million and $25 million, an increase from its previous guidance of between $19 million and $23 million. This increase is primarily attributable to the Company electing to make an investment in a second supplier for ZYFLO CR in an effort to reduce its dependence on sole-source suppliers, enhance efficiencies in the supply chain and reduce future product costs. The net cash expenditure projection includes the anticipated receipt of an additional $5 million milestone payment in 2007 from the co-promotion agreement with DEY, but excludes the impact of any future business development agreements, such as co-development deals for the alpha-7 program or the zileuton R(+) or injection programs.

About Critical Therapeutics Critical Therapeutics, Inc. is developing and commercializing innovative products for respiratory, inflammatory and critical care diseases. The Company owns worldwide rights to two FDA-approved drugs for the prevention and chronic treatment of asthma in patients 12 years of age and older: twice-daily ZYFLO CR(TM) (zileuton) extended-release tablets and ZYFLO(R) (zileuton tablets). Critical Therapeutics is working to develop products for acute asthma attacks that lead patients to the emergency room and other urgent care settings. The Company also is developing therapies directed toward the body's inflammatory response. Critical Therapeutics is located in Lexington, Mass. For more information, please visit www.crtx.com. About ZYFLO CR and ZYFLO ZYFLO CR(TM) and ZYFLO(R) are the only FDA-approved leukotriene synthesis inhibitors for the prophylaxis and chronic treatment of asthma in adults and children 12 years of age and older. ZYFLO CR and ZYFLO are not indicated for use in the reversal of bronchospasm in acute asthma attacks. Therapy with ZYFLO CR and ZYFLO can be continued during acute exacerbations of asthma. ZYFLO CR uses SkyePharma PLC's (LSE: SKP) proprietary Geomatrix(R) drug delivery technology, which controls the amount and rate of drug released into the body. The recommended dose of ZYFLO CR is two 600 mg extended-release tablets twice daily, within one hour after morning and evening meals, for a total daily dose of 2400 mg. The recommended dose of ZYFLO is one 600 mg immediate-release tablet four times a day for a total daily dose of 2400 mg. Important Safety Information about ZYFLO CR and ZYFLO ZYFLO CR and ZYFLO are contraindicated in patients with active liver disease or transaminase elevations greater than or equal to three times the upper limit of normal. A small percentage of patients treated with ZYFLO CR (2.5%) and ZYFLO (1.9%) in placebo-controlled trials showed an increased release of a liver enzyme known as ALT and bilirubin (an orange or yellowish pigment in bile). As a result, the level of liver enzymes in patients treated with ZYFLO CR and ZYFLO should be measured by a simple blood test. It is recommended that physicians perform this test before administering ZYFLO CR and ZYFLO and repeat the test on a regular basis while patients are on the medication. Patients taking ZYFLO CR or ZYFLO and theophylline should reduce the theophylline dose by 50%. Patients taking ZYFLO CR or ZYFLO and propranolol or warfarin should be monitored and doses adjusted as appropriate. Most common side effects associated with the use of ZYFLO CR and ZYFLO are sinusitis, nausea and pharyngolaryngeal pain and abdominal pain, upset stomach and nausea, respectively.

About Perforomist(TM) Inhalation Solution Perforomist(TM) Inhalation Solution is indicated for the long-term, twice-daily (morning and evening) administration in the maintenance treatment of bronchoconstriction in patients with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema. Important Safety Information about Perforomist(TM) Inhalation Solution Perforomist(TM) Inhalation Solution belongs to a class of medications known as long-acting beta(2)-adrenergic agonists (LABAs). LABAs may increase the risk of asthma-related death. Data from a large placebo-controlled US study comparing the safety of another LABA (salmeterol) or placebo added to usual asthma therapy showed an increase in asthma-related deaths in patients receiving salmeterol. This finding with salmeterol may apply to formoterol (a LABA), the active ingredient in Perforomist(TM) Inhalation Solution. Perforomist(TM) Inhalation Solution should not be used in patients with acutely deteriorating COPD or to treat acute symptoms. Acute symptoms should be treated with fast-acting rescue inhalers. Perforomist(TM) Inhalation Solution should not be used with other medications containing LABAs. Do not use more than one nebule twice daily. Perforomist(TM) Inhalation Solution should be used with caution in patients with cardiovascular disorders. Perforomist(TM) Inhalation Solution is not a substitute for inhaled or oral corticosteroids. The safety and efficacy of Perforomist(TM) Inhalation Solution in asthma has not been established. In COPD clinical trials, the most common adverse events reported with Perforomist(TM) Inhalation Solution were diarrhea, nausea, nasopharyngitis, dry mouth, vomiting, dizziness, and insomnia.
