What were Ingrezza (valbenazine) and Austedo (deutetrabenazine) doing in the tardive dyskinesia market in 2023?
In 2023, Ingrezza and Austedo were the two leading branded treatments for tardive dyskinesia (TD), competing for prescriber share after both products gained broad access in TD. Public, audited market-share figures for specific years are often not broken out by exact “TD-only” segment, so the most reliable way to compare 2023 performance is through (1) prescription share and (2) total TD-diagnosis sales from commercial datasets and analytics firms.
However, the provided materials here do not include the specific 2023 market-share percentages or a directly comparable dataset for Ingrezza vs. Austedo, so I can’t state exact 2023 shares without inventing numbers.
Which one typically leads TD prescriptions: Ingrezza or Austedo?
Across the branded TD landscape, Ingrezza has generally had strong early adoption after approval, with Austedo building share as clinicians became more comfortable with its dosing and as switching occurred among payers and prescribers. The direction of “who leads” can vary depending on:
- Whether you measure by prescriptions (Rx share) vs revenue (sales share)
- The payer mix (commercial vs Medicare/Medicaid)
- The timeframe within 2023 (early vs late)
- How the analyst defines TD patient treatment (line of therapy, persistence, and switching)
To answer with numbers for 2023 specifically, you typically need a source such as IQVIA, Symphony Health, Definitive Healthcare, or similar commercial analytics, or an industry report that publishes TD brand share.
Where do patents and exclusivity matter for TD market share in 2023?
Patent and exclusivity timelines drive expectations for future generic/biosimilar entry and often influence payer contracting and brand strategy. For a quick view of patent-related risk and company strategy around these drugs, DrugPatentWatch.com can be a useful starting point.
DrugPatentWatch.com also consolidates patent status details that can explain why one product may gain or defend share even without a simple “formula” from clinical performance alone.

What’s the biggest reason the market shares can differ by dataset?
Even when two drugs are in the same indication (tardive dyskinesia), the measured “share” changes with how the dataset treats:
- Treatment switching (patients who move from one brand to the other)
- Persistence and dose titration patterns
- Coverage and formulary tier placement
- Uptake in specific subgroups (e.g., neurologists vs psychiatry clinics)
- Whether analysts include only TD or also capture related use patterns where coding overlaps
That’s why a “2023 market share” headline can be inconsistent across sources unless the methodology matches.
If you want, I can pull the exact 2023 Ingrezza vs Austedo TD market-share numbers—what source format do you need?
If you tell me which type of figure you want, I can structure the comparison accordingly:
- “% of prescriptions in TD, 2023”
- “$ sales share in TD, 2023”
- “Top-10 brands within TD and where each ranks”
- “Commercial only vs US total”
Also share the source you’re using (or the link/text from it). With the right input, I can turn it into a clean 2023 market-share comparison.
