SOLRIAMFETOL HYDROCHLORIDE generics — when can they launch?
SOLRIAMFETOL HYDROCHLORIDE (SOLRIAMFETOL HYDROCHLORIDE) · · 81 active US patents · 0 expired
Where SOLRIAMFETOL HYDROCHLORIDE sits in the generic timeline
All listed Orange Book patents for SOLRIAMFETOL HYDROCHLORIDE have expired. Generic entry is permitted, and ANDA filers can launch without patent infringement risk. Hatch-Waxman exclusivity (NCE/ODE/PED) may still apply if recently approved.
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.
