POZEN Receives Approval for MT 100 in the United Kingdom.

CHAPEL HILL, N.C. -- POZEN, Inc. (NASDAQ: POZN), a pharmaceutical company focused primarily on products for the treatment of acute and chronic pain, migraine and other pain-related conditions, announced today the United Kingdom's Medicines and Healthcare Products Regulatory Agency (MHRA) has issued a Marketing Authorization for MT 100 for the acute treatment of migraine.

MT 100 was developed as an oral, first-line treatment for migraine. It is a patented sequential release tablet containing two approved drugs, naproxen sodium, which relieves pain and reduces inflammation, and metoclopramide, which accelerates the absorption of naproxen and contributes to the relief of migraine.

Dr. John R. Plachetka, chairman, president and CEO of POZEN stated, "The authorization for MT 100 by the MHRA is a milestone event for POZEN as it's our first regulatory approval for one of our drug candidates. We are currently seeking a partner who can bring MT 100 to market in the UK and eventually in other countries outside the US."
