Allopurinol Tablets

Orange Book source export date: 2026/11/06. Version: 2026-11-06.

Showing 2 of 2 distinct brand names.

A brand with different source forms or statuses can appear on multiple rows and in both groups. Distinct brand names are counted once globally, with a limit of five.

Verified official English dosage form: Tablets. Listings are grouped by the source dosage form and route; records without a clear correspondence are listed in the other group. Grouping does not establish product equivalence.

Same dosage form

Other dosage forms of the same ingredient

No listings in this group among the displayed brand names.

Same-form/route listings come first, followed by other forms/routes. Within each group, source prescription/OTC listings precede discontinued listings; unknown statuses are last. Each status bucket is ordered by earliest approval date, ascending: pre-1982 records first, missing dates last; ties by brand name, application number and product number. The first five distinct brands in this order are selected globally. All retained source facts for those brands are shown in their own groups; a brand spanning both groups counts once.

Daily collection reads new registrations. Backfill covers registration numbers from 2025 onward (CTR2025/CTR2026), not first-publication years. States are dated observations; revisions are not tracked.

This product is outside the trial-registration backfill scope. New registrations after daily collection started remain in scope. Historical rows may also be found by another product search; neither implies complete historical coverage for this product.

Public-product searches scanned: 7/30; discovered pending details: 13. Record counts in unscanned portions remain unknown.

Filings are counted by acceptance number and filing companies by first applicant. Strengths may have separate applications. Drug names are normalized only for width and whitespace; distinct generic names, dosage forms and combinations remain separate. Unstated strengths are marked. Company counts from different sources must not be added together.

Fact dates are approval dates, acceptance dates, trial first-publication dates or complete-snapshot observation dates, as applicable. Publication and site-observation dates are separate. Historical backfills are not current-period new events. Exit records cover currently inactive applications with an identifiable complete snapshot, not a full review history.
