Primary Issue
Multiple claims are not supported by the supplied FDA prescribing information (pricing/patent/exclusivity, market share/competition, and external website utility).
Suggested Improvement
Limit statements to the label-supported identity, mechanism, and indicated patient populations; remove or clearly de-emphasize non-label market/patent/competition and external-tool claims.
