The state of California has filed a civil suit against units of drugmakers Teva and Allergan , for allegedly obstructing generic competition to Lidoderm transdermal patches. The suit, filed in federal court in San Francisco, alleges a “pay-for-delay” deal between the companies and Endo Pharmaceuticals, which already had its Lidoderm product on the market and had made $825 million off of it in 2011.
