The first patent for Tikosyn (dofetilide) has expired, but no generic versions are available yet. Although it's unclear why no generic versions have been introduced, it's likely that the drug is still protected by another patent that has not yet expired.
Can I Buy Generic Tikosyn?Tikosyn® (dofetilide) is a prescription medication approved to treat certain heart rhythm problems known as atrial fibrillation and atrial flutter. It is approved for use in people who have significant symptoms.
Tikosyn is made by Pfizer Labs. It is protected by patents that prevent any generic Tikosyn from being manufactured in the United States.
When Will a Generic Version Be Available?The first patent for Tikosyn expired in September 2012. However, no generic versions are yet available. This strongly suggests that one or more later-expiring patents are still protecting the drug from generic competition.
Is Dofetilide a Generic Tikosyn?No -- dofetilide is the active ingredient in Tikosyn, but 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, the original medicine must have gone off-patent and another company besides the original manufacturer must make the product.
