CollaGenex Pharmaceuticals, Inc. has announced that Periostat�, its unique systemic therapy for the adjunctive treatment of adult periodontitis, has been awarded the ADA Seal of Acceptance by the American Dental Association.

The ADA states, ``Periostat has been shown to help stop the progression of periodontitis when used as directed as an adjunct to scaling and root planing, in a conscientiously applied program of oral hygiene and regular professional care.'' - Council on Scientific Affairs, American Dental Association.

``Obtaining the ADA Seal is a further confirmation of the safety and efficacy of Periostat,'' noted Brian M. Gallagher, PhD, chairman, president and chief executive officer of CollaGenex. ``It is particularly exciting to receive this acceptance from the ADA, who undertakes a rigorous review, from a clinical perspective, of the safety and efficacy data supporting a new product prior to granting the Seal. This review process assembles opinions from a team of professional dental consultants as well as a panel of scientific council members, including academicians and practicing dentists.''

``Periostat is the first, and only, oral, systemic prescription drug for the treatment of adult periodontitis which has been granted the ADA Seal of Acceptance'', concluded Gallagher.

The ADA Seal of Acceptance is awarded to products that have been shown to meet the ADA's criteria for safety and effectiveness. The ADA Seal is designed to assist dental professionals and consumers to make informed decisions about their use of safe and effective dental products.
