Bromfenac-d4 is intended for use as an internal standard for the quantification of bromfenac by GC- or LC-MS. Bromfenac is an inhibitor of cyclooxygenase 2 (COX-2; IC50 = 6.6 nM) that is selective over COX-1 (IC50 = 210 nM).1 It inhibits prostaglandin E2 production in a rabbit model of LPS-induced eye inflammation. Bromfenac also decreases inflammation following cataract removal in dogs when administered as a 0.9% topical solution on a tapering schedule for 24 weeks.2 Formulations containing bromfenac have been used in the treatment of postoperative inflammation following cataract surgery.
