INDICATION AND USAGE

CLINICAL PHARMACOLOGY
Mechanism of Action
Bromfenac is a nonsteroidal anti-inflammatory drug (NSAID) that has anti-inflammatory activity. The mechanism of its action is thought to be due to its ability to block prostaglandin synthesis by inhibiting cyclooxygenase 1 and 2.
Prostaglandins have been shown in many animal models to be mediators of certain kinds of intraocular inflammation. In studies performed in animal eyes, prostaglandins have been shown to produce disruption of the blood-aqueous humor barrier, vasodilation, increased vascular permeability, leukocytosis, and increased intraocular pressure.
Pharmacokinetics
The plasma concentration of bromfenac following ocular administration of A-NAC Eye Drops (Bromfenac Sodium Ophthalmic Solution) in humans is unknown. Based on the maximum proposed dose of one drop to the eye (0.045 mg) and PK information from other routes of administration, the systemic concentration of bromfenac is estimated to be below the limit of quantification (50 ng/mL) at steady- state in humans.
CONTRAINDICATIONS
None
WARNINGS AND PRECAUTIONS
Sulfite Allergic Reactions
Contains sodium sulfite, a sulfite that may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown and probably low. Sulfite sensitivity is seen more frequently in asthmatic than in non-asthmatic people.
Slow or Delayed Healing
All topical nonsteroidal anti-inflammatory drugs (NSAIDs) may slow or delay healing. Topical corticosteroids are also known to slow or delay healing. Concomitant use of topical NSAIDs and topical steroids may increase the potential for healing problems.
Potential for Cross-Sensitivity
There is the potential for cross-sensitivity to acetylsalicylic acid, phenylacetic acid derivatives, and other NSAIDs. Therefore, caution should be used when treating individuals who have previously exhibited sensitivities to these drugs.
Increased Bleeding Time
With some NSAIDs, there exists the potential for increased bleeding time due to interference with platelet aggregation. There have been reports that ocularly applied NSAIDs may cause increased bleeding of ocular tissues (including hyphemas) in conjunction with ocular surgery.
It is recommended that bromfenac ophthalmic solution be used with caution in patients with known bleeding tendencies or who are receiving other medications which may prolong bleeding time.
ADVERSE REACTIONS
Clinical Trail Experience
The most commonly reported adverse experiences reported following use of Bromfenac after cataract surgery include: abnormal sensation in eye, conjunctival hyperemia, eye irritation (including burning/stinging), eye pain, eye pruritus, eye redness, headache, and iritis. These events were reported in 2-7% of patients.
Post-Marketing Experience
The following events have been identified during post-marketing use of A-NAC Eye Drops (Bromfenac Sodium Ophthalmic Solution)in clinical practice. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. The events, which have been chosen for inclusion due to either their seriousness, frequency of reporting, possible causal connection to topical A-NAC Eye Drops (Bromfenac Sodium Ophthalmic Solution) or a combination of these factors, include corneal erosion, corneal perforation, corneal thinning, and epithelial breakdown.
Treatment:
Treatment should be symptomatic and supportive. Serum electrolyte levels (particularly potassium) and blood pH levels should be monitored. Studies have shown that Timolol does not dialyse readily.
Use In Specific Populations
Pregnancy
Teratogenic Effects: PregnancyCategory C. Reproduction studies performed in rats at oral doses up to 0.9 mg/kg/day (1300times the recommended human ophthalmic dose[RHOD]) and in rabbits at oral doses up to 7.5 mg/kg/day (11,000 times RHOD) revealed no evidence of teratogenicity due to bromfenac. However, 0.9 mg/kg/day in rats caused embryo-fetal lethality, increased neonatal mortality, and reduced postnatal growth. Pregnant rabbits treated with 7.5 mg/kg/day caused increased post implantation loss. There are no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Nonteratogenic Effects:
Because of the known effects of prostaglandin biosynthesis- inhibiting drugs on the fetal cardiovascular system (closure of ductus arteriosus), the use of Bromfenac Ophthalmic Solution during late pregnancy should be avoided.
Nursing Mothers
Caution should be exercised when Bromfenac is administered to a nursing woman.
Pediatric Use
Safety and efficacy in pediatric patients below the age of 18 have not been established.
Geriatric Use
There is no evidence that the efficacy or safety profiles for bromfenac differ in patients 65 years of age and older compared to younger adult patients.
DOSAGE AND ADMINISTRATION
Recommended Dosing
For the treatment of postoperative inammation in patients who have undergone cataract extraction, one drop of bromfenac ophthalmic solution should be applied to the affected eye(s) once daily beginning1 day prior to cataract surgery, continued on the day of surgery, and through the 14 days of the postoperative period.
Use withOther TopicalOphthalmicMedications
Bromfenac ophthalmic solution maybe administered in conjunction with other topical ophthalmic medications such as alpha-agonists, beta-blockers, carbonic anhydrase inhibitors, cycloplegics, and mydriatics. Drops should be administered at least 5 minutes apart.
