- NONSTEROIDAL ANTI-INFLAMMATORY DRUGS
- Pharmaceutical Form : Eye Drops
- Composition : 0.9 mg bromfenac (equivalent to 1.035 mg bromfenac sodium sesquihydrate) /1mL
- Active Substance : bromfenac
Mechanism of action:
Bromfenac is a non-steroidal anti-inflammatory drug (NSAID) that has anti-inflammatory activity which is thought to be due to its ability to block prostaglandin synthesis by inhibiting primarily cyclooxygenase 2 (COX-2). Cyclooxygenase 1 (COX-1) is only inhibited to a small extent.
Bromfenac efficiently permeates the cornea of cataract patients: A single dose resulted in a mean peak aqueous humour concentrations of 79±68 ng/ml at 150-180 minutes after dosing. Concentrations were maintained for 12 hours in aqueous humour with measurable levels up to 24 hours in major ocular tissues including the retina.
Bromfenac shows high binding to plasma proteins. In vitro, the 99.8% were bound to proteins in human plasma.
No biological relevant melanin binding was observed in vitro.
Studies in rabbits using radio-labelled bromfenac have demonstrated that highest concentrations after topical
administration are observed in the cornea followed by the conjunctiva and the aqueous humour. Only low concentrations were observed in the lens and vitreous.
In vitro studies indicate that bromfenac is mainly metabolised by CYP2C9, which is absent in both iris-ciliary body and retina/choroid and the level of this enzyme in the cornea is less than 1% compared to the corresponding hepatic level.
In orally treated humans unchanged parent compound is the major component in plasma. Several conjugated and unconjugated metabolites have been identified with the cyclic amide being the major urinary metabolite.
After ocular administration the half-life of bromfenac in aqueous humour is 1.4 h indicating rapid elimination.
Bromfenac is indicated in adults for the treatment of postoperative ocular inflammation following cataract extraction.
POSOLOGY AND METHOD OF ADMINISTRATION:
Use in adults, including the elderly:
The dose is one drop of BROMO CARE in the affected eye(s) twice daily, beginning the next day after cataract surgery and continuing through the first 2 weeks of the postoperative period.
The treatment should not exceed 2 weeks as safety data beyond this is not available.
For ocular use.
If more than one topical ophthalmic medicinal product is being used, each one should be administered at least 5 minutes apart.
To prevent contamination of the dropper-tip and solution, care must be taken not to touch the eyelids, surrounding areas or other surfaces with the dropper-tip of the bottle.
Hypersensitivity to bromfenac or to any of the excipients listed in section 6.1, or to other non-steroidal anti-inflammatory medicinal products (NSAIDs).
Bromfenac is contraindicated in patients in whom attacks of asthma, urticaria or acute rhinitis are precipitated by acetylsalicylic acid or by other medicinal products with prostaglandin synthetase inhibiting activity.
WARNINGS AND PRECAUTIONS
All topical NSAIDs may slow or delay healing like topical corticosteroids. Concomitant use of NSAIDs and topical steroids may increase the potential for healing problems.
There is the potential for cross-sensitivity to acetylsalicylic acid, phenylacetic acid derivatives, and other NSAIDs.
Therefore, treating individuals who have previously exhibited sensitivities to these medicinal products has to be avoided.
In susceptible patients, continued use of topical NSAIDs, including bromfenac may result in epithelial breakdown, corneal thinning, corneal erosion, corneal ulceration or corneal perforation. These events may be sight threatening.
Patients with evidence of corneal epithelial breakdown should immediately discontinue use of topical NSAIDs and should be closely monitored for corneal health. Consequently in at risk patients concomitant use of ophthalmic corticosteroids with NSAIDs may lead to a higher risk of corneal adverse events.
An acute ocular infection may be masked by the topical use of anti-inflammatory medicinal products.
Use of contact lenses:
In general, contact lens wear is not recommended during the postoperative period following cataract surgery. Therefore, patients should be advised not to wear contact lenses during treatment with Bromfenac.
There are no adequate data from the use of bromfenac in pregnant women. Studies in animals have shown reproductive toxicity. The potential risk for humans is unknown. Since the systemic exposure in non-pregnant women is negligible after treatment with Bromfenac, the risk during pregnancy could be considered low.
However, because of the known effects of prostaglandin biosynthesis-inhibiting medicinal products on the foetal cardiovascular system (closure of ductus arteriosus), the use of Bromfenac during third trimester pregnancy should be avoided. The use of BROMO CARE is in general not recommended during pregnancy unless the benefit outweighs the potential risk.
It is unknown whether bromfenac or its metabolites are excreted in human milk. Animal studies have shown excretion of bromfenac in the milk of rats following very high oral doses. No effects on the breastfed newborn/infant are anticipated since the systemic exposure of the breastfeeding woman to bromfenac is negligible. Bromfenac can be used during breast-feeding.
EFFECTS ON ABILITY TO DRIVE AND USE MACHINES:
Bromfenac has minor influence on the ability to drive and use machines. Transient blurring of vision may occur on instillation. If blurred vision occurs at instillation patients should be advised to refrain from driving or using machines until vision is clear.
