Availability of Generic Tysabri and Understanding Generic Names
When Will Generic Tysabri Be Available?At this time, it is difficult to predict when generic Tysabri might become available. Despite the changing regulations, it is unlikely that a generic version of this drug will be available anytime soon. Tysabri was approved in November 2004, and will likely be protected from generic competitions by patents for at least 12 years from this date.
Is Natalizumab a Generic Tysabri?No -- natalizumab is the active ingredient in Tysabri, 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.
