            POZEN Reports Fourth Quarter and Year End 2004 Results;
                    Completes First Trexima Phase III Study

     CHAPEL HILL, N.C.--(BUSINESS WIRE)--Feb. 28, 2005--POZEN Inc. (NASDAQ:
POZN), today announced results for the fourth quarter and twelve months ended
December 31, 2004.

     Fourth-Quarter Results

     POZEN reported a net loss of $8.4 million, or $0.29 per share on a fully
diluted basis, for the fourth quarter of 2004, compared to a net loss of $1.6
million, or $0.06 per share on a fully diluted basis, for the fourth quarter of
2003.
     Revenue for the quarters ended December 31, 2004 and December 31, 2003
totaled $2.4 and $1.8 million, respectively. Revenue resulted from the
amortization of upfront payments received in 2003 pursuant to collaboration
agreements for MT 100(TM), MT 300(TM), and Trexima(TM), and revenue earned for
conducting additional FDA required Trexima Phase I studies.
     Total operating expenses for the quarter ended December 31, 2004 were $11.1
million as compared to $3.6 million for the same period in 2003. The increase in
operating expenses was due to product development, primarily Trexima Phase III
clinical costs, and general and administrative costs, primarily legal fees,
Sarbanes-Oxley auditing and marketing research.
     At December 31, 2004, cash and cash equivalents totaled $51.8 million
compared to $60.5 million at December 31, 2003.

     Twelve-Month Results

     POZEN reported a net loss of $5.3 million, or $0.18 per share on a fully
diluted basis, for the twelve-month period ended December 31, 2004, compared to
a net loss of $14.9 million, or $0.52 per share on a fully diluted basis, for
the same period of 2003.
     For the twelve months ended December 31, 2004, POZEN reported revenue of
$23.1 million as compared to $3.7 million for the same period of 2003. Revenue
for the period ended December 31, 2004 resulted from the amortization of
payments received under collaboration agreements for MT 100, MT 300, and
Trexima, the receipt of a $15.0 million milestone payment from GlaxoSmithKline
(GSK) for commencement of Phase III clinical trial activities for Trexima and
revenue earned for conducting additional FDA required Trexima Phase I studies.
     Total operating expenses for the twelve months ended December 31, 2004 were
$29.1 million as compared to $19.1 million for the same period in 2003. The
increase in operating expenses was due to higher product development costs,
primarily Trexima Phase III costs.

     Corporate Highlights

     POZEN completed the first of two Phase III pivotal trials for Trexima for
the treatment of migraine headaches. Trexima is GSK's proposed brand name for
the combination of sumatriptan formulated with RT Technology(TM) and naproxen
sodium in a single tablet. GSK and POZEN are collaborating on the development of
Trexima.
     Trexima demonstrated superiority over the individual components measured by
sustained pain-free response (p less than .001) and, with the exception of the
incidence of nausea-free at two hours, all other regulatory endpoints were met
(p less than .001). Trexima did reach statistical significance for the nausea
endpoint compared to placebo after two hours and maintained superiority through
twenty-four hours. All of the active treatments (Trexima, sumatriptan and
naproxen) had a similar incidence of nausea at two hours compared to placebo.
Submission of the new drug application (NDA) with the U.S. Food and Drug
Administration is planned for the second half of 2005.
     POZEN has received a letter from the advisory group (Committee on Safety of
Medicines (CSM)) to the Medicines and Healthcare Products Regulatory Agency
(MHRA) in the United Kingdom agreeing to advise the MHRA that a marketing
authorization be granted for MT 100 in the U.K., provided that POZEN supplies
additional information and meets certain conditions specified in the letter.
POZEN has sent the required information to the U.K.
     POZEN is scheduled to present MT 100 to an FDA Advisory Committee for
consideration, with particular emphasis on the potential risk of tardive
dyskinesia. A tentative date in May 2005 has been proposed.
     POZEN has been issued a European patent covering its MT 400(TM) technology
for proprietary combinations of a triptan (5-HT agonist) and a non-steroidal
anti-inflammatory drug (NSAID) for use in the acute treatment of migraine. The
European patent designates 18 countries in Europe.
     POZEN's board of directors approved the adoption of a stockholder rights
plan, which is similar to plans adopted by many other public companies. The plan
was adopted by the board of directors on January 12, 2005.

     Financial Guidance

     For the first quarter of 2005, POZEN expects total revenues to be
approximately $2.1 million, and total operating expenses to be in the range of
$6 million to $8 million.
     For the 2005 year, POZEN expects total revenue to be approximately $28
million, and total operating expenses to be in the range of $28 million to $32
million. These estimates of revenue and expenses reflect the expected completion
of Trexima Phase III clinical trials and the submission of the resulting NDA.

     POZEN will hold a webcast to present fourth quarter results and
management's outlook on Monday, February 28, 2005 at 11:00 a.m. Eastern time.
