Potential Patient Risk:
Low
Unsupported statements are primarily about FDA approval history, ANDA submission/status, and patent expiration, which are not dosing/safety claims. The only supported pharmacologic mechanism claim does not introduce unsafe dosing or contraindication guidance.

Recommendation
Partially Aligned
Primary Issue
Several regulatory/patent/ANDA claims are not supported by the provided prescribing information excerpts, and the indication claim cannot be fully verified because the Indications and Usage section text is missing.
Suggested Improvement
Limit claims to sections actually provided in the label (e.g., 12.1 Mechanism of Action) and remove/avoid approval history, ANDA submission/status, and patent-expiration assertions unless those details are present in the supplied label text.
