Is there a generic for lubiprostone (Amitza)?

The FDA approved the first generic lubiprostone on November 30, 2021. 6 generic applications are approved; 5 of them carry a current (not discontinued) marketing status in Drugs@FDA; that status is not evidence that the generic is on sale.

FDA's NDC Directory lists lubiprostone from 10 labelers under a generic (ANDA) application and from 2 brand labelers. A listing means the company has registered the product for sale; it does not show that every pharmacy stocks it.

The Orange Book lists 3 patents for Amitiza capsules, the last expiring on October 25, 2027. A patent or exclusivity date is not the date a generic goes on sale: court cases and settlements move it either way.
