Lowey Dannenberg, P.C., Announces Notice of Class Action If You Paid for Some or All of the Purchase Price of Amitiza and or Generic Versions of Amitiza as a Third-Party Payor

WHITE PLAINS, N.Y., March 9, 2026 /PRNewswire/ -- 

If you purchased or paid for some or all of the purchase price of Amitiza
and/or generic versions of Amitiza (Lubiprostone) as a third-party payor,
a class action lawsuit may affect your rights.

Your rights may be affected by a class action lawsuit regarding the price paid for brand and generic Amitiza by third-party payors filed against Defendants Takeda Pharmaceutical Company Limited, Takeda Pharmaceuticals U.S.A., Inc., and Takeda Pharmaceuticals America, Inc. (collectively "Takeda" or "the Defendants"). The lawsuit, which is pending in the District of Massachusetts, alleges Defendants engaged in a scheme to delay generic competition in the market for lubiprostone. Plaintiff alleges Defendants' scheme delayed the entry of generic competition for Takeda's brand name prescription pharmaceutical drug Amitiza for up to five years, causing TPPs to pay supra-competitive prices for Amitiza and its AB-rated alternatives during the relevant time period, and Plaintiff seeks to recover damages from Defendants. The lawsuit asserts that, as a result of Takeda's alleged unlawful conduct, the prices paid for the at-issue drugs were higher than they otherwise would have been.

This is only a summary. The Court has not decided whether Defendants did anything wrong. There is no money available now, and no guarantee there will be. For additional details, please read the Long-Form Notice available at www.AmitizaTPPLitigation.com.
