NCIt definition : The sodium salt form of bromfenac, a nonsteroidal anti-inflammatory drug (NSAID) with
analgesic and anti-inflammatory activities. Upon ophthalmic administration, bromfenac
binds to and inhibits the activity of cyclooxygenase II (COX II), an enzyme which
converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins (PG).
By inhibiting PG formation, bromfenac is able to inhibit PG-induced inflammation,
thereby preventing vasodilation, leukocytosis, disruption of the blood-aqueous humor
barrier, an increase in vascular permeability and an increase in intraocular pressure
(IOP).;
