Nepafenac contains nepafenac, a non-steroidal anti-inflammatory drug (NSAID) specifically formulated for ophthalmic use. Nepafenac is the active therapeutic component used to treat pain and inflammation associated with cataract surgery. It works as a prodrug that penetrates the eye to target inflammatory mediators directly at the site of surgical trauma. This medicine is commonly prescribed to enhance patient comfort and support ocular recovery following surgical procedures. Always use Nepafenac exactly as directed by your doctor.

Nepafenac is an ophthalmic formulation containing nepafenac as the active therapeutic agent. It is designed to deliver targeted anti-inflammatory relief to the ocular tissues after surgical intervention.

Nepafenac is a unique NSAID prodrug. Upon topical application to the eye, it passes through the cornea and is converted by ocular tissue hydrolases into amfenac, a potent active metabolite. Amfenac inhibits the cyclooxygenase (COX-1 and COX-2) enzymes, which are responsible for the synthesis of prostaglandins. Since prostaglandins are the primary chemicals that trigger pain, heat, and swelling in the eye, blocking their production effectively manages the inflammatory response caused by cataract extraction or other ocular surgeries.

This localised mechanism of action allows Nepafenac to provide significant anti-inflammatory and analgesic (pain-relieving) benefits directly to the eye while maintaining very low levels of systemic absorption. This makes it a preferred choice for managing post-operative recovery in patients requiring precise ocular care.

The medication is typically administered as a topical ophthalmic suspension. The frequency and duration of use are determined by an ophthalmologist, usually beginning shortly before the surgical procedure and continuing through the initial healing phase.

The uses of Nepafenac are as follows:

Prevention of Post-Operative Ocular Pain

Nepafenac is used to manage and prevent pain following cataract surgery and other eye procedures.

Treatment of Ocular Inflammation

It is prescribed to reduce redness, swelling, and internal inflammation of the eye tissues after surgical trauma.

Reduction of Macular Oedema Risk

It is frequently used to reduce the risk of postoperative macular oedema (fluid buildup in the retina), particularly in patients with pre-existing risk factors like diabetes.

Improvement of Surgical Recovery

It helps stabilise the ocular environment during the healing window, ensuring a more comfortable recovery process for the patient.

Inhibition of Prostaglandin Synthesis

Nepafenac is used when a targeted, localised inhibitor is needed to block the inflammatory pathways specifically within the eye.

Here are the benefits of Nepafenac:

• Reduces Post-Operative Pain: Nepafenac effectively manages and prevents ocular pain following cataract surgery and other eye procedures.

• Controls Ocular Inflammation: It significantly reduces redness, swelling, and internal inflammation caused by surgical trauma.

• Lowers Risk of Macular Oedema: Regular use helps prevent fluid buildup in the retina (macular oedema), especially in high-risk patients such as those with diabetes.

• Targeted Ocular Action: As a prodrug, it penetrates deep into the ocular tissues to provide relief exactly where the inflammation occurs.

• Minimal Systemic Absorption: Its localised application ensures effective treatment within the eye while minimising side effects in the rest of the body.

• Supports Faster Recovery: By controlling the inflammatory response, it helps the eye heal more comfortably during the critical post-surgical window.

• Improves Patient Comfort: Reduces the "gritty" or painful sensation often experienced by patients immediately after ocular surgery.

Like all medicines, Nepafenac may cause side effects in some individuals, especially during early treatment.

Common Side Effects:

• Visual Disturbance: Temporary blurred vision may occur immediately after applying the drops.

• Foreign Body Sensation: A feeling as if something is in the eye.

• Sticky Sensation: The eye may feel slightly sticky or crusty.

• Ocular Hyperemia: Mild redness or bloodshot appearance of the eye.

• Increased Intraocular Pressure: A slight rise in pressure within the eye may occur in some patients.

Uncommon Side Effects:

• Dry Eye: Some patients may experience a decrease in tear production or dry sensations.

• Punctate Keratitis: Small areas of inflammation on the surface of the cornea.

• Eye Itching: Mild irritation or pruritus in or around the eye.

Serious Side Effects (Require Immediate Medical Attention):

• Corneal Damage: Persistent blurred vision, severe pain, or thinning of the cornea (keratopathy) requires urgent review.

• Severe Allergic Reaction: Swelling of the eyelids, intense itching, rash, or difficulty breathing needs urgent attention.

• Delayed Healing: If the eye does not appear to be healing or if redness worsens significantly, medical evaluation is required.

Always consult your doctor if side effects persist or worsen.

To ensure safe use:

• Use exactly as prescribed by your ophthalmologist.

• Usually administered as a topical ophthalmic suspension (eye drops).

• Shake the bottle well before each use to ensure the medicine is properly mixed.

• Wash your hands before application and avoid touching the dropper tip to any surface to prevent contamination.

• Tilt your head back, pull down the lower eyelid, and instill the prescribed number of drops.

Do not use beyond the prescribed duration without review.

Nepafenac works primarily through Nepafenac, the active therapeutic component that targets ocular inflammation and pain.

Nepafenac is a prodrug that, upon topical application, penetrates the cornea and is converted by ocular tissue hydrolases into amfenac. Amfenac is a potent non-steroidal anti-inflammatory drug (NSAID) that inhibits the cyclooxygenase (COX-1 and COX-2) enzymes. These enzymes are essential for the production of prostaglandins, which are the primary mediators of pain, heat, and swelling in the eye. By blocking prostaglandin synthesis, Nepafenac effectively reduces the inflammatory response triggered by surgical procedures such as cataract extraction.

This localized action ensures that the medication provides high therapeutic concentrations within the eye tissues, specifically targeting the anterior and posterior segments, while maintaining minimal systemic exposure. Together, this mechanism ensures a more comfortable recovery and protects the ocular structures from inflammation-related complications.

A few practical measures can help improve treatment outcomes and ensure safe use of Nepafenac:

• Shake well before use: Always shake the bottle well to ensure the medicine is properly mixed for a consistent dose.

• Remove contact lenses: Do not wear contact lenses while applying the drops. Wait at least 15 minutes after application before reinserting them.

• Practice good hygiene: Wash your hands before use and do not touch the dropper tip to any surface, including your eye, to avoid contamination.

• Wait between medications: If using other eye drops, wait at least 5 minutes between applying Nepafenac and other ocular treatments.

• Follow the full schedule: Continue using the drops for the entire duration prescribed by your surgeon, even if your eye feels better.

Proper storage is important to maintain the stability and effectiveness of Nepafenac:

• Store at room temperature: Keep the bottle in a cool, dry place, typically below 30°C.

• Protect from light: Keep the bottle in its original carton or away from direct sunlight when not in use.

• Keep the bottle tightly closed: Ensure the cap is secured immediately after each use to prevent contamination.

• Keep out of reach of children: Store in a safe location to prevent accidental ingestion or misuse.

• Discard after the prescribed period: Follow the specific instructions on the label regarding how long the bottle remains safe to use after opening (often 28 days).

Nepafenac is applied topically to the eye and is generally not affected by food or drink. However:

• No specific food restrictions: You may use these eye drops regardless of your meal timings.

• Hydration: Maintaining general hydration supports overall ocular health during the healing process.

• Alcohol: While there is no direct interaction, follow your surgeon's advice regarding alcohol consumption during post-operative recovery.

Nepafenac may interact with other topical or systemic medications:

• Topical Steroids: Using Nepafenac concurrently with topical corticosteroids may increase the potential for healing problems (slowed wound healing).

• Anti-Platelet/Anticoagulant Drugs: Use with caution if you are taking blood thinners (like warfarin or aspirin), as topical NSAIDs may increase the risk of bleeding in eye tissues during surgery.

• Other Topical NSAIDs: Avoid using multiple types of NSAID eye drops simultaneously unless specifically directed by an ophthalmologist.

Nepafenac should be used carefully in the following conditions, as Nepafenac may influence ocular healing or bleeding:

• Bleeding Tendencies: Use with caution in patients with known bleeding disorders or those taking medications that prolong bleeding time.

• Diabetes Mellitus: Diabetic patients may be at a higher risk for corneal complications or macular oedema and require close monitoring.

• Complicated Ocular Surgeries: Patients with denervated corneas or corneal epithelial defects may experience increased risk of corneal adverse events.

• Dry Eye Syndrome: Existing ocular surface disease may be exacerbated by the use of topical NSAIDs.

• Rheumatoid Arthritis: Patients with severe autoimmune conditions may have an increased risk of corneal thinning or perforation with prolonged use.

The dose depends on the medical indication and the specific surgical protocol. It is usually administered as one drop in the affected eye(s) three times daily, beginning one day before surgery and continuing for up to two weeks post-operatively, exactly as prescribed.

If a dose is missed, apply the drops as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and resume your regular routine. Do not apply double the amount to make up for a missed dose.
