Primary Issue
Multiple extracted claims are absent or unsupported in the provided FDA-approved label text, including ER/IR formulation, general generic equivalence/market assertions, and a strength specification mismatch (150 mg not listed).
Suggested Improvement
Remove or revise claims not explicitly supported by the provided label excerpts (especially patent/market/pricing/e-pharmacy/generic-equivalence and ER/IR formulation). Align tablet-strength statements to the label-listed strengths (25, 50, 100 mg) and avoid presenting study-specific regimens as general dosing guidelines unless the DOSAGE AND ADMINISTRATION section explicitly supports them.
