At this time, patents currently prevent a generic Potiga (ezogabine) from being manufactured in the United States. The exclusivity rights are expected to expire in June 2016, which would be the earliest date that a generic version might become available. However, certain circumstances could delay this date, such as lawsuits or other patents for new uses of the drug.
Can I Buy Generic Potiga?Potiga™ (ezogabine) is a prescription seizure medication. It is approved only for use in combination with other seizure medications to treat partial-onset seizures in adults age 18 and older.
Potiga is manufactured by Catalent Pharma Solutions for GlaxoSmithKline. It is currently under the protection of exclusivity rights that prevent any generic versions from being manufactured in the United States.
When Will a Generic Version Be Available?The exclusivity rights are currently set to expire in June 2016. This is the earliest predictable date that a generic version could become available.
However, other circumstances could come up to extend or shorten this exclusivity period. This could include such things as lawsuits or other patents for specific Potiga uses. Once the drug goes off-patent, there may be several companies that manufacture a generic Potiga drug.
Is Ezogabine a Generic Potiga?No -- ezogabine is the active ingredient in Potiga, but it is 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 must make the product.
