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 (PGE2; ） 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. | [Uses]
Bromfenac-d4 (sodium) is deuterium labeled Bromfenac (sodium). Bromfenac sodium is a potent and orally active inhibitor of COX, with IC50s of 5.56 and 7.45 nM for COX-1 and COX-2, respectively. Bromfenac sodium is a brominated non-steroidal anti-inflammatory/analgesic agent (NSAID), and it is commonly used for the research of postoperative inflammation and pain following cataract surgery, and pseudophakic cystoid macular edema (CME)[1][2]. | [References]
