Summary
Most claims are not supported by the provided label excerpts or directly conflict with label content (notably receptor selectivity/serotonin transporter statements). Several other assertions (patent/market timing/manufacturer/patent expiry) are not label-supported and therefore unsupported.

No label excerpt provided supporting patent scope or expiry dates.
Ingrezza (tianeptine sulfate) is a selective agonist of the mu-opioid receptor.
Label excerpts provided do not support tianeptine sulfate as the active ingredient nor provide receptor-agonist assertions.
Ingrezza (tianeptine sulfate) is an agonist of the delta-opioid receptor.
Label excerpts provided do not support tianeptine sulfate as the active ingredient nor provide receptor-agonist assertions.
Ingrezza has activity at the serotonin transporter, affecting serotonin reuptake.
Label excerpts provided do not support serotonin transporter/reuptake mechanism.
Ingrezza is manufactured by Neurocrine Biosciences.
No label excerpt provided supporting manufacturer/labeler.
Ingrezza was the first VMAT2 inhibitor approved by the FDA specifically for tardive dyskinesia.
No label excerpt provided supporting comparative 'first' or approval-history claims.
Ingrezza is used as an adjunctive treatment for major depressive disorder.
Provided label excerpts list indications only for tardive dyskinesia and Huntington’s disease chorea; no major depressive disorder adjunctive use is supported.
Ingrezza is approved by the U.S. FDA for the treatment of adults with major depressive disorder.
Provided label excerpts do not list major depressive disorder as an indication.
FDA approval of Ingrezza for tardive dyskinesia was based on clinical trials demonstrating effectiveness in reducing involuntary movements associated with tardive dyskinesia.
The provided label excerpts include indications but do not provide trial evidence/details for tardive dyskinesia effectiveness.
Studies showed that Ingrezza improved depressive symptoms for major depressive disorder when used as an add-on therapy.
Provided label excerpts do not discuss major depressive disorder studies or adjunctive use.
Common side effects of Ingrezza include somnolence.
No adverse reaction excerpt provided in the prompt lists somnolence as a common side effect.
Common side effects of Ingrezza potentially include QT interval prolongation.
No label excerpt provided discussing QT interval prolongation as a (potentially) common side effect.

No label excerpt provided containing the first FDA approval date.
Contradictions
High
AI Statement
Ingrezza (tianeptine sulfate) is a selective agonist of the mu-opioid receptor.
Label Reference
Provided label context identifies valbenazine (valbenazine tosylate) as the active ingredient; no label excerpt supports tianeptine sulfate or mu-opioid receptor agonism.
High
AI Statement
Ingrezza (tianeptine sulfate) is an agonist of the delta-opioid receptor.
Label Reference
Provided label context identifies valbenazine (valbenazine tosylate) as the active ingredient; no label excerpt supports tianeptine sulfate or delta-opioid receptor agonism.
Moderate
AI Statement
Ingrezza has activity at the serotonin transporter, affecting serotonin reuptake.
Label Reference
Provided label excerpts provided do not support serotonin transporter mechanism for INGREZZA/INGREZZA SPRINKLE.
Important Omissions
If discussing adverse reactions or 'common side effects,' the label’s provided excerpt(s) for adverse reactions relevant to the evaluated claims are not included (e.g., no list establishing somnolence or QT prolongation as common/potentially common).
Importance:
Moderate
Safety Assessment
Potential Patient Risk:
High
The response includes multiple unsupported or contradictory mechanistic and indication claims (including incorrect major depressive disorder use and incorrect 'tianeptine sulfate' receptor activity), which could mislead clinical use and risk assessment. The only on-label safety content clearly reflected in the provided excerpts relates to boxed depression/suicidality warning in Huntington’s disease.

Recommendation
Not Aligned
Primary Issue
Major depressive disorder indication and adjunctive/add-on use are not supported by the provided label excerpts; mechanistic claims attribute the wrong active ingredient (tianeptine sulfate) and incorrect receptor activity not supported by the label excerpts.
Suggested Improvement
Restrict claims to label-supported information from the provided excerpts (indications for tardive dyskinesia and Huntington’s disease chorea; boxed warning/monitoring for depression and suicidal ideation/behavior in Huntington’s disease) and remove unsupported or contradictory assertions (patent expiry, manufacturer, first-in-class claims, market availability date, major depressive disorder use, and the receptor/serotonin transporter statements).
