Can I Buy Generic Lotronex?
Lotronex is made by Patheon, Inc., for Prometheus Laboratories, Inc. The drug is protected from generic competition by patents that have not yet expired.
When Will a Generic Version Be Available?
The first patent for Lotronex expired in January 2013. This was the earliest predictable date that a generic version could have become available. However, at this time no generic manufacturer makes a generic version of Lotronex. This could be because Lotronex is protected by another patent that does not expire until October 2018.
Once Lotronex goes off-patent, there may be several companies that manufacture a generic version of it. However, it is unknown if this is the case. Lotronex is associated with potentially serious bowel side effects. As a result, it is reserved for only the most severe IBS cases, after other treatments have been tried. Because of its restricted use, it is unclear whether generic manufacturers will choose to make a generic Lotronex drug even after it goes off-patent.
Is Alosetron a Generic Lotronex?
No -- alosetron is the active ingredient in Lotronex, not a generic version of it. What can be confusing is that the active ingredient of a drug is often referred to as the "generic name." The generic name is different from a generic version of a medicine.
In order for there to be a generic version of a medicine, the original medicine must have gone off-patent, and another company besides the original manufacturer would make the product.
