Perrigo Company Confirms Patent Challenge of Monistat(R) 1 Combination Pack

ALLEGAN, Mich., April 21 /PRNewswire-FirstCall/ .- Perrigo Company today announced that it has filed an Abbreviated New Drug Application (ANDA) for over-the-counter (OTC) Miconazole Nitrate Vaginal Cream, 2% and Suppository, 1.2g, a generic version of Monistat(R) 1 Combination Pack. The Company believes that it is the first to file an ANDA with a Paragraph IV certification against Monistat 1.

Monistat 1 Combination Pack (miconazole nitrate vaginal cream, 2% and suppository, 1.2g) is an antifungal medication indicated for the treatment of vaginal yeast infections, and had sales of approximately $50 million through food, drug and mass merchandisers for the 12 months ended March 2008, as measured by Information Resources, Inc.

Perrigo filed its ANDA for Miconazole Nitrate Vaginal Cream, 2% and Suppository 1.2g containing a Paragraph IV Certification with the U.S. Food & Drug Administration and notified Johnson & Johnson, the New Drug Application holder for Monistat 1 Combination Pack, and McNeil-PPC, Inc., the listed patent owner, of its filing. On April 18, 2008, McNeil filed suit alleging patent infringement in the United States District Court for the District of New Jersey to prevent Perrigo from proceeding with the commercialization of its product. This action formally initiates the patent process under the Hatch-Waxman Act.
