Understanding Bromfenac: An Ophthalmic NSAID
Bromfenac is a type of nonsteroidal anti-inflammatory drug (NSAID) delivered in an ophthalmic (eye drop) solution. Unlike oral NSAIDs used for general pain relief, bromfenac is specifically formulated for topical application to the eye. Its primary purpose is to address the pain and swelling that often accompany eye surgery, particularly cataract removal. As a prescription-only medication, it should be used exactly as directed by a healthcare provider.
How Bromfenac Works
The mechanism of bromfenac's anti-inflammatory action lies in its ability to inhibit the synthesis of prostaglandins. Prostaglandins are hormone-like substances in the body that play a significant role in causing inflammation, pain, and swelling. By inhibiting the cyclooxygenase (COX) enzymes—specifically favoring COX-2, which is more active at sites of inflammation—bromfenac prevents the production of these inflammatory mediators. This targeted action helps to resolve intraocular inflammation and reduce pain effectively at the site of the surgical procedure.
The Main Application: Post-Cataract Surgery Recovery
Bromfenac is most commonly prescribed for patients who have undergone cataract extraction. The procedure, while routine, causes a certain degree of trauma to the eye tissue, leading to an inflammatory response. This inflammation can cause discomfort, blurred vision, and slower recovery. Bromfenac addresses these issues directly, leading to quicker pain resolution and reduced inflammation.
Administration
Bromfenac is available in several brand-name ophthalmic solutions. The frequency of use is determined by your prescribing healthcare provider. The treatment regimen often begins one day prior to surgery and continues for a specific period determined by your doctor.
Proper administration is crucial for effectiveness and safety. Always wash your hands before and after use. Tilt your head back, pull down the lower eyelid to create a pouch, and instill the prescribed number of drops. Avoid touching the dropper tip to your eye or any other surface to prevent contamination. If other eye drops are prescribed, they should be administered at least five minutes apart unless otherwise instructed.
Bromfenac vs. Other Ophthalmic NSAIDs
Bromfenac is not the only NSAID eye drop used in ophthalmology. Other options like ketorolac (Acular) and nepafenac (Ilevro) are also available. Differences in potency, administration frequency, and specific indications exist, allowing doctors to choose the best option for each patient.
| Feature | Bromfenac (e.g., Prolensa®) | Ketorolac (e.g., Acular®) | Nepafenac (e.g., Ilevro®) |
|---|---|---|---|
| Potency | Higher potency against COX-2. | Effective, but with different COX inhibition profile. | High corneal permeability; converted to active form in eye. |
| Typical Dosing | Varies by brand and prescription, typically once or twice daily post-cataract surgery. | Varies by condition and prescription. | Varies by brand and prescription, typically once daily post-cataract surgery. |
| Primary Use | Pain and inflammation after cataract surgery. | Post-cataract inflammation, allergic conjunctivitis itch. | Post-cataract inflammation and pain. |
| FDA Approval | Approved for adults. | Approved for younger patients (age 2+) for some uses. | Approved for younger patients (age 10+). |
Important Safety Considerations
While generally well-tolerated, bromfenac does carry risks and potential side effects that patients should be aware of.
Potential Side Effects
- Common: Burning or stinging upon application, blurry vision, eye pain, itchy eyes, headache, and feeling that something is in the eye.
- Less Common but Serious: Corneal complications (thinning, perforation), delayed wound healing, and bleeding inside the eye (hyphema). The risk increases with longer-term use, complicated surgery, or underlying conditions like diabetes.
Contraindications and Precautions
- Allergies: Do not use if you are allergic to bromfenac, aspirin, or other NSAIDs. Bromfenac formulations may also contain sulfites, which can cause severe allergic reactions in sensitive individuals, especially those with asthma.
- Medical Conditions: Caution is advised for patients with a history of bleeding disorders, diabetes, rheumatoid arthritis, dry eye syndrome, or complicated eye surgeries.
- Contact Lenses: Soft contact lenses should be removed before administration and can be reinserted after a specific time interval recommended by your doctor or the product labeling.
Conclusion
In conclusion, bromfenac is a powerful and specific NSAID eye drop used to manage the inflammation and pain that follow cataract surgery. Its targeted inhibition of prostaglandin synthesis helps patients recover more comfortably and quickly. While effective, its use requires adherence to a healthcare provider's instructions, careful consideration of potential side effects, and awareness of the precautions necessary for safe use. Patients should always consult their ophthalmologist to determine if bromfenac is the right choice for their post-operative care.

List of Key Takeaways
- Primary Use for Bromfenac: It is a prescription ophthalmic solution primarily used to treat pain and inflammation in adults following cataract surgery.
- Mechanism of Action: As an NSAID, bromfenac works by inhibiting cyclooxygenase (COX) enzymes, particularly COX-2, to reduce the production of inflammatory prostaglandins.
- Administration: The medication is delivered as eye drops, with frequency of use varying by brand and individual prescription.
- Important Precautions: Patients with allergies to aspirin or other NSAIDs, as well as those with certain eye conditions or diabetes, should use bromfenac with caution.
- Contact Lens Use: Soft contact lenses must be removed before applying bromfenac and can be reinserted after a time interval recommended by a healthcare professional.
- Common Side Effects: Mild eye irritation, foreign body sensation, and blurred vision are among the more common, though usually temporary, side effects.
- Serious Complications: Rare but serious risks include corneal damage and allergic reactions. Any signs of serious adverse effects should be reported to a doctor immediately.
