VILOXAZINE HYDROCHLORIDE generics — when can they launch?
VILOXAZINE HYDROCHLORIDE (VILOXAZINE HYDROCHLORIDE) · · 18 active US patents · 0 expired
Where VILOXAZINE HYDROCHLORIDE sits in the generic timeline
Imminent generic cliff: earliest active US patent for VILOXAZINE HYDROCHLORIDE expires in 2029 (~3 years from today). ANDA filers are likely already preparing Paragraph IV certifications. Expect first-filer 180-day exclusivity competition imminently.
Under US Hatch-Waxman, a generic enters via an ANDA (Abbreviated New Drug Application) and may file with one of four Paragraph IV certifications attacking the brand's listed patents. If the brand sues within 45 days, a 30-month FDA approval stay is triggered. First Para IV filer typically gets 180-day market exclusivity.
