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.

Who is responsible for this application?
Application holder is not the same as manufacturer
Manufacturer status
Not established by the Orange Book
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.
Regulatory interpretation
What the record means, and what it does not
FDA marketing status
1 presentation listed as on the Discontinued Drug Product List
A discontinued-list entry does not, by itself, show why marketing stopped or whether FDA determined the product was withdrawn for safety or effectiveness.
Therapeutic equivalence
No TE code is posted for this application
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.
Patent & exclusivity record
27 listed patent expirations and 2 exclusivity dates remain on or after Jul 26, 2026
The latest future date recorded across those files is May 03, 2038. Patent and FDA exclusivity operate independently, can overlap, and do not by themselves predict a generic launch date.
Same-ingredient landscape
0 other ANDAs and 0 other NDAs found
0 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.
Which products are meaningfully comparable?
Exact ingredient + dosage form + route cohorts
NDA 211723 appears in 1 comparison cohort. These groups narrow the same-ingredient landscape, but strength and TE code must still match before interpreting therapeutic equivalence.

Why are clinical sections unavailable?
Exact application-label matching status
Exact source match queuedQueue NDA-211723
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.

Scope, limitations, and primary sources
What to verify before making a decision
- The applicant is the holder of legal responsibility for the application; the Orange Book does not establish that the applicant manufactured or currently markets every listed product.
- RX, OTC, and discontinued are FDA listing categories, not real-time pharmacy inventory or commercial-availability data.
- Therapeutic equivalence applies only within the matching ingredient, dosage form, route, strength, and TE-code group; same ingredient alone is insufficient.
- Listed patent and exclusivity dates are regulatory intelligence, not legal advice, a freedom-to-operate analysis, or a reliable generic-launch forecast.
- The Orange Book is not prescribing information and does not provide indications, dosing, contraindications, adverse reactions, recalls, or current safety communications.
Official FDA references
- Electronic Orange Book record
- Orange Book preface and TE-code policy
- FDA product, patent, and exclusivity data files
Data shown here is normalized for search and comparison. When a regulatory, substitution, launch, or legal decision turns on a field, verify it against the current FDA record and the relevant source document.
