Private-label omeprazole gets final OK

FDA grants final approval to Israel-based Dexcel Pharma Technologies' 20 mg omeprazole delayed-release tablets, Perrigo announces Dec. 10. Perrigo will be the exclusive marketer and distributor of the store brand Prilosec OTC, and plans to begin distribution of the product during the first quarter of 2008, the Allegan, Mich.-private labeler states.

Allegan, Mich.-based Perrigo has exclusive U.S. marketing and distribution rights for Dexcel's product. Perrigo says FDA's final approval of the generic Prilosec OTC will not come until the expiration of the 30-month period provided for AstraZeneca under the Hatch-Waxman Act, which would be November 2008. However, trial is expected to begin later this year in U.S. District Court for Delaware in the patent infringement suit AstraZeneca filed in May 2006 against Dexcel, alleging the Israel-based firm's application infringes on three patents: two expiring in October 2007 and one in May 2019. The litigation initiated the patent challenge process under Hatch-Waxman (1"The Tan Sheet" June 12, 2006, p. 5)...
