FDA application holder
Supernus Pharmaceuticals Inc
The Orange Book identifies this organization as the applicant responsible for NDA 208944.
Amantadine Hydrochloride
Gocovri contains Amantadine Hydrochloride and is the new drug FDA Orange Book record for NDA 208944. The application has 2 presentations with strength, dosage-form, route, status, RLD/RS, TE, patent, and exclusivity context. Current inventory and clinical labeling are not established without an application-matched source.
New drug application identity from the Orange Book snapshot.
The listed applicant holds the FDA application; this field does not establish the product manufacturer.
Each FDA product number remains tied to its own strength, dosage form, route, and status.
Orange Book marketing categories do not establish real-time inventory or commercial availability.
RLD and RS designations are presentation-specific, not inferred from the trade name.
Therapeutic-equivalence codes apply only within the matching Orange Book product heading.
A zero means none appear in this snapshot, not that no patent rights exist.
FDA exclusivity and listed patent protection are distinct regulatory concepts.

Marketing status, TE code, RLD, and RS are presentation-level fields. Never transfer one product number's designation to another presentation.
FDA application holder
The Orange Book identifies this organization as the applicant responsible for NDA 208944.
Manufacturer status
A product-specific FDA label or NDC source must independently identify a manufacturer, labeler, distributor, packager, repackager, or relabeler. The applicant name is not used as a substitute for that evidence.
RX and OTC are Orange Book marketing categories, not real-time inventory signals. Confirm current commercial availability with labeling, the application holder, or an authoritative drug listing.
No TE code does not mean FDA found the product ineffective or non-equivalent. FDA generally publishes TE evaluations for multisource prescription products; single-source and some other products may have no code.
The latest future date recorded across those files is Aug 23, 2038. Patent and FDA exclusivity operate independently, can overlap, and do not by themselves predict a generic launch date.
22 of the related ANDA applications are not marked discontinued. Sharing an ingredient does not establish pharmaceutical or therapeutic equivalence; strength, dosage form, route, and TE group still matter.
NDA 208944 appears in 1 comparison cohort. These groups narrow the same-ingredient landscape, but strength and TE code must still match before interpreting therapeutic equivalence.
Amantadine Hydrochloride
No exact application-level FDA or DailyMed label match has been reviewed for this application. Approved uses, dosing, warnings, adverse reactions, and clinical evidence remain unavailable rather than being inherited from a related brand, generic, or ingredient record.
Until an exact application match passes human review, this page intentionally omits approved uses, dosing, warnings, adverse reactions, mechanism, and clinical-study summaries. It never inherits those claims from an RLD, brand, generic, or same-ingredient product.
