Teva sues Apotex over Coreg infringement

TRENTON, N.J. Teva has sued Apotex to prevent it from selling a generic version of the heart medication Coreg, according to Bloomberg.

The two companies, as well as other generic drug makers, received approval from the Food and Drug Administration to sell a generic version on Sept. 5.  Teva says it owns four patents that cover various forms and processes to make the generic, carvedilol. The company also said that Apotex might have to buy the compound made using the patented process in order to sell the generic.

The lawsuit was filed yesterday in a federal court in New Jersey. Coreg had sales of $853.8 million in the first six months of 2007.
