           Critical Therapeutics Reports Financial Results
                 for the Quarter Ended March 31, 2007

   ZYFLO Prescriptions Grow 56% on Unit Basis Over Prior Year Period

     Quarter Highlighted By Co-promotion Agreement With Dey, L.P.


    LEXINGTON, Mass.--(BUSINESS WIRE)--May 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 first quarter ended March 31, 2007.

    For the three months ended March 31, 2007, the Company posted a
net loss of $4.7 million, or $0.11 per share, based on 42.5 million
weighted average shares outstanding. This compares with a net loss of
$16.7 million, or $0.49 per share, for the same period in 2006, based
on 34.1 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.

    During the first quarter of 2007, sales of ZYFLO(R) (zileuton
tablets) totaled $2.9 million, an increase of 183 percent over the
same period last year and 49 percent over the fourth quarter of 2006
under U.S. generally accepted accounting principles. Through the end
of 2006, revenue from product sales of ZYFLO was recognized 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 converted to recognizing revenue from
sales of ZYFLO when the product is shipped to third parties, less an
estimate of expected product returns. This change resulted in a net
increase in product sales of approximately $953,000 in the first
quarter of 2007. Going forward, revenue per prescription should be
positively impacted by a six percent price increase for ZYFLO that was
implemented in April 2007.

    As part of the Company's March 2007 co-promotion agreement with
Dey, L.P. (DEY), an affiliate of Merck KGaA in Germany, DEY's
200-person sales force began promoting ZYFLO on April 30, 2007. Under
the agreement, Critical Therapeutics and DEY will jointly promote the
twice-daily, controlled-release formulation of zileuton (zileuton CR),
subject to regulatory approval, with a combined sales force of
approximately 240 representatives.

    The total number of ZYFLO prescriptions filled in the first
quarter of 2007 was 9,248, compared with 5,938 in the first quarter of
2006, an increase of 56 percent, and 9,404 in the fourth quarter of
2006, a decrease of 1.7 percent. The total number of prescriptions for
ZYFLO continues to increase on a quarterly basis in territories where
sales representatives still promote ZYFLO. These prescription data are
based on third-party data purchased by the Company.

    "The financial and operational results reflect the significant
progress we have made in restructuring and focusing the Company. We
have realigned our cost structure to give us more financial
flexibility while investing in more focused development opportunities
to drive value going forward," said Frank Thomas, Critical
Therapeutics' President and Chief Executive Officer. "DEY is a strong
co-promotion partner that provides us with additional resources to
help ensure that ZYFLO and zileuton CR achieve their potential. This
co-promotion arrangement provides substantial commercial resources
behind zileuton CR and reduces the risk associated with launching this
important product on our own, pending regulatory approval."

    Cash and short-term investments as of March 31, 2007 totaled $46.0
million, compared with $49.0 million at December 31, 2006. Net cash
used in the first quarter of 2007 was $3.1 million, which was
positively impacted by the $3.0 million payment that the Company
received from DEY in connection with the signing of the co-promotion
agreement for zileuton. This compares with net cash used of $9.9
million in the fourth quarter of 2006 and $18.2 million in the first
quarter of 2006. The Company ended the first quarter of 2007 with
approximately 43.1 million shares of common stock outstanding,
excluding warrants and stock options.

    Recent Developments

    Since the beginning of 2007, Critical Therapeutics has
accomplished the following:

    --  Signed a co-promotion agreement with DEY that leverages the
        expertise of both companies in the U.S. respiratory market. A
        combined sales force of approximately 220 U.S. sales
        representatives is currently promoting ZYFLO. Pending
        regulatory approval by the FDA of zileuton CR, a combined
        sales force of more than 240 U.S. sales representatives will
        be promoting zileuton CR to more than 15,000 physicians
        (allergists, pulmonologists and primary care physicians)
        across the country.

    --  Gained co-promotion rights to a second product that allows
        Critical Therapeutics to increase the efficiency of and
        leverage its sales force. DEY and Critical Therapeutics signed
        a binding letter agreement that allows Critical Therapeutics
        to promote DEY's clinical candidate for Chronic Obstructive
        Pulmonary Disease (COPD), if approved by the FDA. A more
        detailed written agreement between the two companies is being
        finalized.

    --  Continued to increase unit volume and sales of ZYFLO in
        territories staffed by a sales representative.

    --  Received a product development fee from Beckman Coulter, which
        exercised its option to continue to license patent rights
        relating to developing a diagnostic to detect and measure
        levels of HMGB1 in the bloodstream.

    --  Licensed to Innovative Metabolics, Inc. (IMI) certain
        intellectual property rights related to the development and
        commercialization of medical device approaches to stimulating
        the vagus nerve. Upon the completion of IMI's financing in May
        2007, Critical Therapeutics received 400,000 shares of junior
        preferred stock of IMI and a license fee of $400,000, after
        payments to The Feinstein Institute.

    --  Executed a publication strategy to enhance the scientific and
        medical understanding of our commercial and development
        programs through a series of Critical Therapeutics co-authored
        publications in peer-reviewed medical journals, including the
        following:



  Zileuton:
    -- Respiratory Medicine electronically published a peer-reviewed
       article based on a study comparing zileuton with a low-dose
       inhaled corticosteroid (beclomethasone dipropionate) to
       doubling the dose of beclomethasone. The results suggest that
       zileuton with a low dose beclomethasone improves lung function
       and may be an effective therapeutic approach to achieving
       asthma control in patients with moderate to severe persistent
       asthma. The print version of the article will be published in
       the June issue of Respiratory Medicine.

    -- International Journal of Clinical Practice published a paper
       reviewing multiple articles on the clinical development of
       zileuton for asthma in its April 2007 issue. This publication
       was a summation of several previously published articles.

  Alpha-7:
    -- Shock published preclinical research work in its April 2007
       issue demonstrating that a small molecule alpha-7 agonist
       attenuated endotoxin-induced inflammation and peritoneal influx
       of neutrophils by a mechanism separate from anti-TNF.

    -- Critical Care Medicine published an article in April 2007 in
       which a selective alpha-7 receptor agonist was shown to improve
       survival in murine endotoxemia and severe sepsis.

  HMGB1:
    -- Nature Immunology published an article in May 2007
       demonstrating that HMGB1 is a critical part of DNA complexes
       that can stimulate immune cells to produce potent inflammatory
       mediators, suggesting that HMGB1 antibodies could be an
       effective therapeutic for the treatment of Lupus and other
       chronic autoimmune diseases.

    -- Journal of Leukocyte Biology published a paper in January 2007
       describing a method, the ELISPOT, that provides a novel tool to
       study pathways promoting or inhibiting HMGB1 secretion.


    Financial Results for the Three Months Ended March 31, 2007 and
2006

    Total revenue for the three months ended March 31, 2007 was $3.5
million, compared with $2.3 million for the same period in 2006, an
increase of 54 percent.

    Revenue for the first quarter of 2007 included:

    --  Sales of ZYFLO that accounted for $2.9 million in revenue,
        compared with $1.0 million in the first quarter of 2006 and
        $1.9 million in the fourth quarter of 2006. Through the end of
        2006, revenue from ZYFLO was recognized 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 converted to recognizing revenue
        from sales of ZYFLO when the product is shipped to third
        parties, less an estimate of expected product returns.

    --  Collaboration revenue of $601,000 from Critical Therapeutics'
        HMGB1 collaboration with MedImmune, Inc. and its license
        agreement with Beckman Coulter, Inc. to develop HMGB1
        diagnostic assays. This compares with collaboration revenue of
        $1.3 million in the first quarter of 2006. The decrease in the
        revenue under collaboration agreements resulted from a decline
        in the Company's obligations associated with the HMGB1
        program. As the HMGB1 program advances into later stages of
        preclinical development, a larger portion of the costs and
        activities are being assumed by MedImmune resulting in lower
        revenue recognized by the Company under its collaboration
        agreement. In future periods, the Company's collaboration
        revenue under the MedImmune agreement will increase in periods
        when milestones are achieved. As of March 31, 2007, the
        Company has $105,000 of revenue deferred under its
        collaboration agreement with MedImmune.

    Total operating expenses for the three months ended March 31, 2007
decreased $11.0 million, or 56 percent, to $8.7 million, compared with
$19.7 million for the same period in 2006.

    Total operating expenses for the first quarter of 2007 included:

    --  Cost of products sold that totaled $741,000, including
        $166,000 related to previously deferred revenue, resulting in
        gross margins on net sales of ZYFLO of approximately $2.2
        million, or 74 percent. This compares to cost of products sold
        of $504,000 and gross margins of 51 percent in the first
        quarter of 2006.

    --  Research and development (R&D) expenses that decreased $6.5
        million, or 69 percent, to $2.9 million in the first quarter
        of 2007, compared with $9.4 million for the first quarter of
        2006. This decrease was primarily due to lower expenses
        associated with the Company's clinical trials, as well as the
        reduction in the number of employees performing R&D activities
        following the Company's 2006 restructurings.

    --  Sales and marketing expenses that decreased $4.9 million, or
        71 percent, to $2.0 million in the first quarter of 2007,
        compared with $6.9 million in the first quarter of 2006. This
        decrease was primarily associated with the 2006 reduction in
        the sales force.

    --  General and administrative (G&A) expenses that increased
        slightly to $3.1 million, compared with $2.9 million in the
        first quarter of 2006. Cost savings in G&A expenses resulting
        from the 2006 restructurings were offset by consulting, legal
        and advisory fees associated with the Company's co-promotion
        agreement with DEY.

    --  Stock-based compensation expense, as calculated under SFAS
        123(R), totaled $1.0 million for the quarter ended March 31,
        2007, compared with $1.4 million in the first quarter of 2006.

    Research & Development Update

    Critical Therapeutics is progressing its preclinical and
development programs and expects to initiate three clinical trials
during 2007.

    Zileuton CR Clinical Trial

    The Company currently plans to conduct a clinical trial evaluating
zileuton CR as an add-on therapy to moderate doses of inhaled
corticosteroids in asthma patients to support the sales and marketing
of zileuton CR, pending regulatory approval. The Company expects to
begin enrolling patients in this trial in the second quarter of 2007.

    Injectable Formulation of Zileuton (zileuton injection)

    The Company is developing an injectable formulation of zileuton
for use in emergency room or urgent care settings for patients
experiencing acute exacerbations of asthma and other acute
hospital-based pulmonary conditions. The Company expects to initiate a
Phase II clinical trial in the second half of 2007 following favorable
results from 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.

    Zileuton Life Cycle Extension Program

    The Company is currently pursuing life cycle extension strategies
to enhance the 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.
Critical Therapeutics plans to initiate a Phase I clinical trial in
the second half of 2007 examining the pharmacokinetic profile of the R
isomer of zileuton. Development of the R isomer may lead to potential
dosing improvements for patients.

    Alpha-7

    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 two exploratory development candidates from
a series of proprietary lead molecules. The Company is conducting
non-GLP (Good Laboratory Practice) toxicology studies with these
candidates before selecting a lead clinical candidate to take into GLP
toxicology studies. The Company believes that this innovative
anti-inflammatory approach will have 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

    The Company's HMGB1 program, which is partnered with MedImmune,
Inc., continues to make progress toward the identification of a first
clinical candidate. The collaboration has narrowed down potential
clinical candidates to a few fully human antibodies that have shown
efficacy in pre-clinical models of arthritis. The joint development
team expects to select a clinical candidate for the development of
HMGB1 antibodies for chronic inflammatory disease, such as rheumatoid
arthritis or Lupus, in 2007. The collaboration also is making progress
with the development of HMGB1 antibodies for acute inflammatory
diseases, such as sepsis. According to the terms of the Company's
collaboration agreement with MedImmune, the obligations of both
companies remain unchanged as a result of MedImmune's recently
announced sale to AstraZeneca PLC, and the two companies expect to
continue to move forward with the HMGB1 program.

    Financial Guidance

    For the year ending December 31, 2007, the Company is projecting
net cash expenditures to be between $19 million and $23 million. These
projections include the anticipated receipt of an additional $9
million in milestone payments in 2007 from DEY related to the approval
and launch of zileuton CR, but exclude the impact of any future
business development agreements, such as co-development deals for
alpha-7, zileuton life cycle extension or zileuton injection.

    Under the DEY co-promotion agreement signed in the first quarter
of 2007, Critical Therapeutics has deferred the $3 million payment
received upon signing. The $3 million payment will be amortized over
the term of the agreement, along with any future milestone payments
received from DEY. The Company expects to record all ZYFLO sales
generated by the combined sales force and record any co-promotion fees
paid to DEY as an operating expense.

    Because the milestone payments are being amortized in future
years, the Company expects a net loss for 2007 of between $31 million
and $35 million, or between $0.72 and $0.81 per share, assuming 43
million shares outstanding. Research and development expenses for 2007
are expected to be between $16 million and $20 million, including
approximately $3.1 million in milestone payments that would be due to
third parties upon the approval of zileuton CR. Sales and marketing
expenses are expected to increase in the second half of 2007 as the
Company prepares for the commercial launch of zileuton CR and
increases the size of its sales force to approximately 40 sales
representatives. These estimates for 2007 include the impact of
non-cash charges related to stock-based compensation expense for
employees and non-employees of approximately $3.0 million.

    Critical Therapeutics expects net cash expenditures to be between
$4 million and $6 million in the second quarter of 2007, based on a
net loss of between $9 million and $11 million, or $0.21 to $0.26 per
share. These projections assume that zileuton CR is approved during
the second quarter of 2007 and the Company receives a $4 million
milestone payment from DEY.

    About ZYFLO(R)/Zileuton

    ZYFLO(R) (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 broncospasm 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-more-upper limit
of normal. For full prescribing information, please visit
www.crtx.com/pat_pi.html or call the Company's toll free telephone
number 1-866-835-8216 to request medical information.
