The Orange Book identifies this organization as the applicant responsible for ANDA 216421.
Azelastine Hydrochloride
Azelastine Hydrochloride Allergy contains Azelastine Hydrochloride and appears in 2 FDA Orange Book applications. ANDA 216421 is the lead filing, with 1 presentation 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.

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 ANDA 216421.
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.
This means none appear for this application in the current Orange Book files. It is not a freedom-to-operate opinion and does not rule out unlisted patents, regulatory barriers, or product-specific rights.
11 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.
ANDA 216421 appears in 1 comparison cohort. These groups narrow the same-ingredient landscape, but strength and TE code must still match before interpreting therapeutic equivalence.
Azelastine 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.
