Market share: how much of tardive dyskinesia treatment does Ingrezza vs Austedo take?
From the information provided here, there are no figures on market share, prescription share, or revenue share for Ingrezza (valbenazine) versus Austedo (deutetrabenazine). To quantify “market share,” you typically need a source that reports sales or prescriptions by product (for example, pharmacy claims, IQVIA/Aver, Symphony Health, company earnings, or market research reports).
If you share the market-study dataset you’re using (or the country/segment, such as US retail vs total prescriptions vs hospital) I can help you interpret it.
How Ingrezza and Austedo compete for tardive dyskinesia patients
Both drugs are used for tardive dyskinesia and are commonly compared directly as VMAT2 inhibitors, but market share depends on factors like formulary access, payer restrictions, dosing convenience, and how often clinicians switch between therapies. Without access to sales/claims numbers in your prompt, the only accurate answer is that market share cannot be determined from the provided information.
What usually drives brand switching and share between these two drugs
Even without numeric share, real-world competition between Ingrezza and Austedo usually turns on:
- Payer coverage and prior authorization rules (step therapy, failure requirements, restrictions by TD severity)
- Dosing and adherence (daily convenience and whether regimens differ in practice)
- Safety/tolerability patterns that influence prescriber preference
- Brand presence in formularies and specialty pharmacy distribution
These drivers are exactly the inputs market-research analysts use to explain shifts in share over time.
