FDA application holder
Endo Operations Ltd
The Orange Book identifies this organization as the applicant responsible for NDA 021610.
Oxymorphone Hydrochloride
Opana ER contains Oxymorphone Hydrochloride and appears in 2 FDA Orange Book applications. NDA 021610 is the lead filing, with 7 presentations shown in detail; the other exact-name filings are listed separately. The page preserves strength, dosage form, route, status, RLD/RS, TE, patent, and exclusivity facts. Clinical labeling requires an exact application-matched source.
Every filing shown uses the exact FDA product name; the lead filing supplies the detailed presentation view.
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.

The Orange Book identifies this organization as the applicant responsible for NDA 021610.
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.
A discontinued-list entry does not, by itself, show why marketing stopped or whether FDA determined the product was withdrawn for safety or effectiveness.
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 Nov 22, 2029. Patent and FDA exclusivity operate independently, can overlap, and do not by themselves predict a generic launch date.
7 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 021610 appears in 1 comparison cohort. These groups narrow the same-ingredient landscape, but strength and TE code must still match before interpreting therapeutic equivalence.
Oxymorphone 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.
