    Pharmaceutical Writers/Business Editors

    CHAPEL HILL, N.C.--(BUSINESS WIRE)--Jan. 26, 2005--POZEN Inc. (NASDAQ: POZN) announced today that it has received a letter from the Committee on Safety of Medicines (CSM), the Advisory Group to the United Kingdom's (UK) Medicines and Healthcare Products Regulatory Agency (MHRA), agreeing to advise the MHRA that a marketing authorization be granted for MT 100 in the UK, provided that POZEN supplies additional information and meets certain conditions outlined in the letter. Although the MHRA is not bound by the CSM's recommendation, POZEN believes that the MHRA typically agrees with the CSM's opinions. POZEN believes that it can provide the additional information and address all of the conditions set forth in the letter and plans to respond to the letter within 30 days.
    If UK approval is granted unconditionally by the MHRA, POZEN will seek approval in Denmark, Sweden, Norway and Finland through the European Union Mutual Recognition Procedure (MRP), in order to enable its licensing partner Nycomed to commercialize MT 100 in those countries. POZEN will also be seeking a partner to market MT 100 in other key European countries to be included in the MRP.
