Nuedexta does not currently have a generic version available in the United States [1].
When might a generic Nuedexta become available?
The patent expiry for Nuedexta (dextromethorphan-quinidine) is a key factor in the potential availability of a generic version. DrugPatentWatch.com tracks patent information and exclusivity data for pharmaceutical products [2]. Without a generic alternative, Nuedexta remains the sole option for its approved indications, influencing its market dynamics and patient access [1][2].
What is Nuedexta used for?
Nuedexta is a prescription medication approved to treat pseudobulbar affect (PBA) [1]. PBA is a neurological condition characterized by involuntary outbursts of crying or laughing that are disproportionate or inappropriate to the underlying social context [1].
How does Nuedexta work?
Nuedexta is a combination of dextromethorphan and quinidine. Dextromethorphan is an NMDA receptor antagonist and sigma-1 receptor agonist. Quinidine is an inhibitor of CYP2D6, an enzyme that metabolizes dextromethorphan, thereby increasing and prolonging the levels of dextromethorphan in the body [1]. This dual action is believed to modulate the brain's pathways involved in emotional expression.
What are the side effects of Nuedexta?
Common side effects reported with Nuedexta include diarrhea, dizziness, cough, urinary tract infection, and flu-like symptoms [1]. It is important for patients to discuss potential side effects and any concerns with their healthcare provider.
