Yes, bendamustine is available in different formulations, including intravenous (IV) and oral versions. The patent status can vary for these different formulations and their associated delivery methods [1]. For example, patents may cover specific manufacturing processes, formulations that improve stability or efficacy, or even new indications for the drug [4].
Who Manufactures Bendamustine?
The original developer and marketer of bendamustine in the United States was Teva Pharmaceuticals under the brand name Treanda®.
