Even though the first patent for the drug has expired, Alimta (pemetrexed) is not yet available in generic form. Pemetrexed is the generic name for Alimta; however, this is not the same as a generic version of the drug.
Can I Buy Generic Alimta?Alimta® (pemetrexed) is a prescription medication used to treat certain types of lung cancer and mesothelioma. It belongs to a group of chemotherapy medications known as antimetabolites, folate antagonists, or antifolates.
Alimta is made by Eli Lilly. It is currently under the protection of a patent that prevents any generic Alimta from being manufactured in the United States.
When Will a Generic Version Be Available?
The first patent for Alimta expired in September 2011, yet no generic versions of the drug are available. This strongly suggests that other, later-expiring patents are still protecting the drug from generic competition. The next patent is set to expire in January 2017. At this point, this is the earliest predictable date that a generic version of Alimta could become available.
However, circumstances could extend or shorten this exclusivity period. This could include such things as other patents for specific Alimta uses or lawsuits.
