What ILEVRO is used for

Ilevro is used to:

  • prevent and treat pain and inflammation of the eye associated with cataract surgery
  • reduce risk of postoperative macular oedema associated with cataract surgery in patients with non proliferative diabetic retinopathy.

Ilevro contains the active substance nepafenac. It belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs).

NSAIDs relieve pain and reduce inflammation (e.g. swelling, redness and throbbing).

Your doctor may have prescribed Ilevro for another reason. Ask your doctor if you have any questions about why Ilevro has been prescribed for you.

There is no evidence that Ilevro is addictive.

Use in children

Ilevro Eye Drops are not recommended in children and young adults aged under the age of 18 years as the safety and efficacy in children has not been established.

Use in pregnancy and in breastfeeding

Ilevro Eye Drops should not be used in women of child bearing potential who are not using a contraceptive.

Ilevro Eye Drops is not recommended during breast feeding.

Before you use ILEVRO

When you must not use it

Do not use Ilevro if:

  • you have an allergy to nepafenac, or any of the ingredients in Ilevro listed at the end of this leaflet
  • you have an allergy to other non-steroidal anti-inflammatory drugs (NSAIDs). Examples of NSAIDs are: aspirin, ibuprofen, ketoprofen, diclofenac
  • you have experienced asthma, skin allergy, or intense inflammation in your nose when using other NSAIDs.

Some of the symptoms of an allergic reaction may include:

  • shortness of breath
  • wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other parts of the body
  • rash, itching or hives on the skin.

Do not wear soft contact lenses when you are using Ilevro as the preservative, benzalkonium chloride, can discolour soft lenses and may cause eye irritation. Additionally, wearing contact lenses is not recommended after cataract surgery

Do not use Ilevro if:

  • the bottle/packaging shows signs of tampering
  • the expiry date on the bottle/carton has passed.
    If it has expired or is damaged, return it to your pharmacist for disposal.
    If you use this medicine after the expiry date has passed, it may not work.

If you are not sure whether you should start using Ilevro, talk to your doctor.

Before you start to use it

Tell your doctor if you have had an allergy to any other medicines or any other substances, such as foods, preservatives or dyes.

Tell your doctor if you are pregnant or intend to become pregnant.

Tell your doctor if you are breastfeeding or intend to breastfeed.

Tell your doctor if you have or have had any medical conditions, particularly the following:

  • known bleeding tendency, or have bleeding problems or have had them in the past
  • any other eye disorder (e.g. an eye infection or dry eye) or if you are using other medicines in the eye (especially topical steroids)
  • complicated eye surgery or repeated eye surgery within a short period of time
  • diabetes mellitus
  • rheumatoid arthritis.
  • ocular surface disease (eg. dry eye syndrome).

If you have not told your doctor about any of the above, tell them before you use Ilevro.

Using or taking other medicines

Tell your doctor or pharmacist if you are taking or using any other medicines, including any medicines that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines and Ilevro may interfere with each other.

These include:

  • prostaglandin analogue medicines. Examples include latanoprost, travoprost, bimatoprost and tafluprost that are used to treat glaucoma
  • steroid medicines used to treat inflammation
  • other NSAIDs
  • any medicines which may prolong bleeding time.

These medicines may be affected by Ilevro, or may affect how well it works. You may need different amounts of your medicines or you may need to take different medicines.

Your doctor or pharmacist has more information on medicines to be careful with or avoid while using Ilevro.

How to use ILEVRO

Carefully follow all directions given to you by your doctor and pharmacist. They may differ from the information contained in this leaflet.

If you are being changed from one medicine to another, follow your doctor’s instructions carefully as to when to stop the medicine and when to start the new eye drops.

If you do not understand the instructions on the carton, ask your doctor or pharmacist for help.

How much to use

For pain and inflammation:
The usual dose of Ilevro is one drop in the affected eye(s) daily beginning 1 day before cataract surgery, continued on the day of surgery and for as long as your doctor tells you to.

An additional drop should be administered 30 to 120 minutes prior to surgery.

For the reduction in the risk of postoperative macular oedema:
The usual dose of Ilevro is one drop in the affected eye(s) daily, beginning 1 day before cataract surgery, continued on the day of surgery and up to 60 days after surgery or for as long as your doctor tells you to.

An additional drop should be administered 30 to 120 minutes prior to surgery.

How to use it

It is important to use Ilevro exactly as your doctor or pharmacist has told you.

If you use the drops less often than prescribed, they may not work as well and the eye problem may not improve.

Using the drops more often than prescribed may not improve the eye problem any faster and may cause increased side effects.

Follow these steps to use the Ilevro eye drops 4 mL round shaped dropper bottle:

  1. Wash your hands thoroughly with soap and water.
  2. Shake the bottle.
  3. Remove the cap from the bottle. If a safety seal around the neck of the bottle is present and is loose, remove before using product.
  4. Hold the bottle upside down in one hand between your thumb and middle finger (see Diagram 1).

  1. While tilting your head back, gently pull down the lower eyelid of your eye to form a pouch/pocket.
  2. Place the tip of the bottle close to your eye. Do not let it touch your eye.
  3. Release one drop into the pouch/pocket formed between your eye and eyelid by gently tapping (see Diagrams 2a and 3) or pressing the base of the bottle with your forefinger (see Diagrams 2b and 3).

  1. Close your eye. Do not blink or rub your eye.
  2. While your eye is closed, place your index finger against the inside corner of your eye and press against your nose for about two minutes. This will help to stop the medicine from draining through the tear duct to the nose and throat, from where it can be absorbed into other parts of your body. This will also reduce the unpleasant taste sensation that some people experience when using these drops.
  3. If necessary, repeat the above steps for the other eye.
  4. Your eyelids can only hold less than one drop at a time, so it is normal for a small amount of the eye drop to spill onto your cheek. You should wipe away any spillage with a tissue.
  5. Replace the cap on the bottle, closing it tightly.
  6. Wash your hands again with soap and water to remove any residue.

Follow these steps to use the Ilevro eye drops 4 mL oval shaped dropper bottle:

  1. Wash your hands before you start.
  2. Shake well before use.
  3. Turn the closed bottle upside down and shake down once before each use.
  4. Twist off the bottle cap.
  5. After cap is removed, if a tamper evident snap collar is present and is loose, remove before using product.
  6. Hold the bottle, pointing down, between your thumb and fingers.
  7. Tilt your head back.
  8. Pull down your lower eyelid with a clean finger, until there is a 'pocket' between the eyelid and your eye. The drop will go in here (Diagram 1).

  1. Bring the bottle tip close to the eye, do not let it touch your eye. Do this in front of a mirror if it helps.
  2. Gently squeeze the sides of the bottle until one drop is released into your eye (Diagram 2).

  1. Close your eye. Do not blink or rub your eye.
  2. While your eye is closed, place your index finger against the inside corner of your eye and press against your nose for about two minutes. This will help to stop the medicine from draining through the tear duct to the nose and throat, from where it can be absorbed into other parts of your body. This will also reduce the unpleasant taste sensation that some people experience when using these drops.
  3. If you use drops in both eyes, repeat the steps for your other eye. It is not necessary to close and shake the bottle between administrations for both eyes. Close the bottle cap firmly immediately after use.

You may feel a slight burning sensation in the eye shortly after using the eye drops. If this persists, or is very uncomfortable, contact your doctor or pharmacist.

Be careful not to touch your eye, eyelid or anything else with the dropper tip. This will help prevent the drops becoming dirty or contaminated.

After using Ilevro, wait at least 5 minutes before putting any other eye treatments in your eye. Eye ointments should be put in last.

When to use it

Use Ilevro every day, at about the same time each day, unless your doctor tells you otherwise. Using your eye drops at the same times each day will help you remember when to use the eye drops.

How long to use it

Continue using Ilevro for as long as your doctor prescribes.

If you are unsure about when or how to stop using Ilevro, you should talk to your doctor or pharmacist.

If you forget to use it

If it is almost time for your next dose, skip the dose you missed and use your next dose when you are meant to.

Otherwise, use the drops as soon as you remember and then go back to using them as you would normally.

Do not use double the amount to make up for the dose that you missed. Using multiple doses may cause unwanted side effects.

If you are not sure whether to skip the dose, talk to your doctor or pharmacist.

If you have trouble remembering to use your eye drops, ask your pharmacist for some hints.

If you use too much (overdose)

If you accidentally put several drops in your eye(s), immediately rinse your eye(s) with warm tap water.

If you think that you or anyone else may have swallowed any, or all, of the contents of a bottle of Ilevro, immediately telephone your doctor or Poisons Information Centre on 13 11 26 for advice, or go to Accident and Emergency at your nearest hospital. Do this even if there are no signs of discomfort or poisoning.

If Ilevro is accidentally swallowed, or if you use too many drops, you may feel light-headed, nauseous or dizzy.

While you are using ILEVRO

Things you must do

Avoid sunlight during treatment with Ilevro. Your eyes may be more sensitive to light while you are using Ilevro.

Tell your doctor if you have any crusty discharge from your eyes while using Ilevro. This may mean your eyes are infected and you may need additional treatment.

Tell your doctor if you have any eye pain, tearing, blurry vision or any other changes to the surface of the eye. Use of topical NSAIDs, including Ilevro may result in inflammation of the corneal surface of the eye and other corneal problems.

If you are about to start taking any new medicine, tell your doctor and pharmacist that you are using Ilevro.

Tell all the doctors, dentists and pharmacists who are treating you that you are using Ilevro.

Tell your doctor if, for any reason, you have not used Ilevro exactly as prescribed. Otherwise, your doctor may think that the eye drops were not effective and change the treatment unnecessarily.

Tell your doctor if your symptoms persist, worsen or recur.

Tell your doctor immediately if you become pregnant or decide to breastfeed.

Things you must not do

Do not use Ilevro to treat other complaints unless your doctor tells you to.

Do not give Ilevro to anyone else, even if they have the same condition as you.

Do not stop using Ilevro without first talking to your doctor.

The preservative in Ilevro (benzalkonium chloride) may be deposited in soft contact lenses. You can put your soft contact lenses back into your eyes 15 minutes after you have used Ilevro.

Things to be careful of

Be careful driving, operating machinery or performing tasks requiring mental alertness and/or physical coordination until you know how Ilevro affects you and your vision. As with any eye medicine, temporary blurred vision or other visual disturbances may affect the ability to drive or use machinery in some people. If blurred vision occurs when you use your drops, wait until your vision is clear before driving or operating machinery.

Side effects

Tell your doctor as soon as possible if you notice any of the following effects in the eye(s) and the eye area, and they worry you.

This medicine helps most people but can have unwanted side effects in a few people. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.

Do not be alarmed by the following list of possible side effects. You may not experience any of them.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor or pharmacist if you notice any of the following effects in the eye(s) and the eye area, and they worry you:

  • red, watery eyes, sensitive to light
  • changes in vision, blurred vision or temporary reduction of vision
  • impaired eye healing
  • damage to the surface of the eye, such as thinning or perforation
  • clouding of the eye
  • swelling of the eye

Additional side effects noticed more rarely in the eye(s) / area include:

  • feeling of having something in the eye
  • eye pain
  • eyelid margin crusting
  • deposits or scars on the eye surface
  • eye discomfort
  • eyelid swelling
  • dry eye
  • eye / eyelid inflammation
  • eye irritation
  • itchy eye
  • eye discharge
  • eye allergy (allergic conjunctivitis)

These are uncommon side effects of Ilevro.

Occasionally, some people notice unwanted effects in the rest of their body after using Ilevro.

These effects may include:

  • headache
  • dizziness
  • nausea, vomiting
  • increased blood pressure
  • allergic dermatitis
  • excess of skin in the upper or lower eyelid.

If any of the following happen, stop using Ilevro and tell your doctor immediately or go to Accident and Emergency at your nearest hospital:

  • skin rash
  • swelling of the face, hands or feet
  • wheezing, difficulty in breathing
  • shortness of breath
  • severe and sudden onset of pinkish, itchy swellings on the skin, also called hives or nettle rash.

These hypersensitivity reactions can be very serious side effects. You may need urgent medical attention or hospitalisation. These side effects are very rare.

Tell your doctor if you notice anything else that is making you feel unwell. Other side effects not listed above may also occur in some people.

After using ILEVRO

Storage

Store Ilevro in a cool dry place away from direct sunlight where the temperature stays below 25°C.

Do not store Ilevro or any other medicine in the car, in the bathroom, on a window sill or in any other warm, damp place. Heat and dampness can destroy some medicines.

Do not leave the top off the bottle for any length of time, to avoid contaminating the eye drops.

Keep it where children cannot reach it. A locked cupboard at least one and a half metres above the ground is a good place to store medicines.

Disposal

Write the date on the bottle when you open the eye drops and throw out any remaining solution after four weeks. Eye drops contain a preservative that helps prevent germs growing in the solution for the first four weeks after opening the bottle. After this time, there is a greater risk that the drops may become contaminated and cause an eye infection.

If your doctor tells you to stop using Ilevro or they have passed their expiry date, ask your pharmacist what to do with any remaining solution.

BRAND INFORMATION

Brand name

Ilevro

Active ingredient

Nepafenac

Schedule

S4

 

1 Name of Medicine

Nepafenac.

2 Qualitative and Quantitative Composition

The active ingredient in Ilevro eye drops is nepafenac 3 mg/mL (0.3%).
May contain potential allergens: benzoates, sulfur dioxide/sulfites and hydroxybenzoates from the manufacturing process.
For the full list of excipients, see Section 6.1 List of Excipients.

3 Pharmaceutical Form

Ilevro is a light yellow to yellow, uniform suspension for multiple-dose topical ophthalmic use.
Nepafenac is a yellow crystalline powder which is poorly soluble in water.

4 Clinical Particulars

4.1 Therapeutic Indications

Ilevro is indicated for the:
prevention and treatment of postoperative pain and inflammation associated with cataract surgery;
reduction in risk of postoperative macular oedema associated with cataract surgery in patients with non proliferative diabetic retinopathy.

4.2 Dose and Method of Administration

For ophthalmic use only.
For individual patient use only.
Shake the bottle well before use. After cap is removed, if a tamper evident snap collar is present and loose, remove before using Ilevro.
If more than one topical ophthalmic medicinal product is being used, the medicinal products must be administered at least 5 minutes apart. Eye ointments should be administered last.
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. Instruct patients to keep the bottle tightly closed when not in use.
For the prevention and treatment of pain and inflammation, the dose is 1 drop of Ilevro in the conjunctival sac of the affected eye(s) once a day beginning 1 day prior to cataract surgery and continued on the day of surgery. In clinical studies, the effectiveness of Ilevro was demonstrated for up to 14 days of the postoperative period. Treatment durations greater than two weeks and a dosing frequency of more than once daily have not been assessed. An additional drop should be administered 30 to 120 minutes prior to surgery.
For the reduction in the risk of postoperative macular oedema associated with cataract surgery in patients with non proliferative diabetic retinopathy, the dose is 1 drop of Ilevro in the conjunctival sac of the affected eye(s) once daily beginning 1 day prior to cataract surgery, continued on the day of surgery and up to 60 days of the postoperative period as directed by the clinician. An additional drop should be administered 30 to 120 minutes prior to surgery.
Nasolacrimal occlusion and gently closing the eyelid after instillation are recommended. This may reduce the systemic absorption of eye drops and result in a decrease in systemic adverse reactions.
If a dose is missed, one drop should be administered as soon as possible before reverting to the regular dosage routine. Do not use double the amount to make up for the dose that was missed. Using multiple doses may cause unwanted side effects.

4.3 Contraindications

Hypersensitivity to the active substance nepafenac or to any of the excipients in Ilevro.
Hypersensitivity to other nonsteroidal anti-inflammatory drugs (NSAIDs).
Patients in whom attacks of asthma, urticaria or acute rhinitis are precipitated by acetylsalicylic acid or other NSAIDs.
Soft contact lenses should not be used with Ilevro because the benzalkonium chloride preservative may be absorbed by these lenses.

4.4 Special Warnings and Precautions for Use

For ophthalmic use, not for oral ingestion.
Patients should be instructed to avoid sunlight during treatment with Ilevro.

Ocular effects.

Use of topical NSAIDs may result in keratitis. In some susceptible patients, continued use of topical NSAIDs 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 Ilevro and should be monitored closely for corneal health.
Post-marketing experience with topical NSAIDs suggests that patients with complicated ocular surgeries, corneal denervation, corneal epithelial defects, diabetes mellitus, ocular surface diseases (e.g. dry eye syndrome), rheumatoid arthritis or repeat ocular surgeries within a short period of time may be at increased risk for corneal adverse reactions which may become sight threatening. Topical NSAIDs should be used with caution in these patients. Post-marketing experience with topical NSAIDs also suggest that use more than 24 hours prior to surgery or use beyond 14 days post-surgery may increase patient risk and severity of corneal adverse events.
There have been reports that ophthalmic NSAIDs may cause increased bleeding of ocular tissues (including hyphaemas) in conjunction with ocular surgery. Use Ilevro with caution in patients with known bleeding tendencies or who are receiving other medicinal products which may prolong bleeding time.
An acute ocular infection may be masked by the topical use of anti-inflammatory medicines. NSAIDs do not have any antimicrobial properties. In case of ocular infection, their use with anti-infectives should be undertaken with care.

Use in hepatic impairment/ renal impairment.

Ilevro has not been studied in patients with hepatic disease or renal impairment. Nepafenac is eliminated primarily through biotransformation and the systemic exposure is very low following topical ocular administration. No dose adjustment is warranted in these patients.

Concomitant therapy.

There are very limited data on the concomitant use of prostaglandin analogues and Ilevro. Considering their mechanisms of action, the concomitant use of these medicinal products is not recommended.

Delayed healing.

Topical 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. Therefore, it is recommended that caution should be exercised if Ilevro is administered concomitantly with corticosteroids, particularly in patients at high risk for corneal adverse reactions described below.

Contact lenses.

Contact lens wear is not recommended during the postoperative period following cataract surgery. Therefore, patients should be advised not to wear contact lenses unless clearly indicated by their doctor.

Benzalkonium chloride.

Ilevro contains benzalkonium chloride which may cause eye irritation and is known to discolour soft contact lenses.
Soft contact lenses should not be used with Ilevro because the benzalkonium chloride preservative may be absorbed by these lenses.
Benzalkonium chloride has been reported to cause punctate keratopathy and/or toxic ulcerative keratopathy. Since Ilevro contains benzalkonium chloride, close monitoring is required with frequent or prolonged use.

Cross-sensitivity.

There is a potential for cross-sensitivity of nepafenac to acetylsalicylic acid, phenylacetic acid derivatives and other NSAIDs.

Paediatric use.

The safety and efficacy of Ilevro in children and adolescents has not been established and its use is not recommended for use in patients under 18 years of age.

Use in the elderly.

No data available.

Effects on laboratory tests.

No data available.

4.5 Interactions with Other Medicines and Other Forms of Interactions

In vitro studies have demonstrated a very low potential for interaction with other medicinal products and protein binding interactions.
Neither nepafenac nor amfenac inhibit any of the major human cytochrome P450 (CYP1A2, 2C9, 2C19, 2D6, 2E1 and 3A4) metabolic activities in vitro at concentrations up to 3000 nanogram/mL. Therefore, interactions involving CYP-mediated metabolism of concomitantly administered medicinal products are unlikely. Interactions mediated by protein binding are also unlikely.
There are very limited data on the concomitant use of prostaglandin analogues and Ilevro. Considering their mechanisms of action, the concomitant use of these medicinal products is not recommended.
Concomitant use of topical NSAIDs and topical steroids may increase the potential for healing problems. Concomitant use of Ilevro with medications that prolong bleeding time may increase the risk of haemorrhage.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

There are no data on the effect of Ilevro on human fertility. In male rats, oral dosing of nepafenac decreased sperm motility but did not impair reproductive performance at estimated systemic exposure more than 300 times clinical exposure, based on AUC for nepafenac and amfenac. At similar high exposures in female rats, oral dosing of nepafenac did not impair fertility but did not increase the rate of early resorptions. At the no-effect dose in rat fertility studies (3 mg/kg/day), estimated systemic exposure (AUC) was greater than 80 times clinical exposure.
(Category C)
Ilevro should not be used by women of childbearing potential not using contraception.
There are no adequate data regarding the use of nepafenac in pregnant women. Studies in animals have shown nepafenac and/or its metabolites cross the placenta and are associated with reproductive toxicity. In oral reproduction studies performed with nepafenac in rats, there was no evidence of teratogenicity but maternally toxic doses of 10 mg/kg/day or greater were associated with dystocia, increased postimplantation loss, and reduced fetal weights, growth, and survival (systemic exposure more than 800 times clinical exposure, based on total AUC for nepafenac and amfenac). Oral administration of 3 mg/kg/day or greater from early gestation to weaning was associated with maternal mortality around parturition (exposure about 170 times clinical exposure based on AUC), with higher, maternotoxic doses linked to reductions in live births and pup survival and growth. In pregnant rabbits, oral administration of 30 mg/kg/day during organogenesis produced slight maternotoxicity and a statistically significant increase in the incidence of litter malformations (exposure about 1000 times clinical exposure, based on AUC). The no-effect dose of 10 mg/kg/day was associated with AUC exposure 135 times clinical exposure. The potential risk for humans is unknown.
Since the systemic exposure in non-pregnant women is negligible after treatment with Ilevro, the risk during pregnancy could be considered low. Nevertheless, as inhibition of prostaglandin synthesis may negatively affect pregnancy and/or embryonal/ fetal development and/or parturition and/or postnatal development, Ilevro is not recommended during pregnancy.
It is unknown whether nepafenac is excreted in human milk. Animal studies have shown excretion of nepafenac and/or its metabolites in the milk of rats. However, no effects on the suckling child are anticipated since the systemic exposure of the breastfeeding woman to nepafenac is negligible. The use of nepafenac or Ilevro is not recommended during lactation. Also see Section 4.6 Fertility, Pregnancy and Lactation, Use in pregnancy.

4.7 Effects on Ability to Drive and Use Machines

Temporary blurred vision or other visual disturbances may affect the ability to drive or use machines. If blurred vision occurs at instillation, the patient must wait until the vision clears before driving or using machinery.

4.8 Adverse Effects (Undesirable Effects)

Adverse events in clinical trials.

In clinical studies involving over 1900 patients receiving Ilevro eye drops, suspension, the most frequently reported adverse reactions were punctate keratitis, keratitis, foreign body sensation in eyes and eye pain which occurred in between 0.4% and 0.1% of patients.

Patients with non proliferative diabetic retinopathy.

In the two clinical studies involving 594 patients, patients were exposed to Ilevro eye drops, suspension treatment for 90 days for the prevention of macular oedema post cataract surgery. The most frequently reported adverse reaction was punctate keratitis which occurred in 1% of patients, resulting in a frequency category of common. The other most frequently reported adverse reactions were keratitis and foreign body sensation in eyes which occurred in 0.5% and 0.3% of patients, respectively both adverse reactions with a frequency category of uncommon.
Additional adverse events have been observed in clinical trials with the use of nepafenac 1 mg/mL eye drops, suspension and may also be observed with the use of Ilevro.
Description of selected adverse reactions. Clinical trial experience for the long-term use of Ilevro for the prevention of macular oedema post cataract surgery in patients with non proliferative diabetic retinopathy is limited. Ocular adverse reactions in diabetic patients may occur at a higher frequency than observed in the general population.
Patients with evidence of corneal epithelial breakdown including corneal perforation should immediately discontinue use of Ilevro and should be monitored closely for corneal health.

Paediatric population.

The safety and efficacy of Ilevro in children and adolescents have not been established.
When nepafenac is prescribed to a patient with non proliferative diabetic retinopathy post cataract surgery to prevent macular oedema, the existence of any additional risk factor should lead to reassessment of the foreseen benefit/risk and to intensify patient monitoring. The safety and efficacy of Ilevro in patients with proliferative diabetic retinopathy, vitreomacular traction or epiretinal membrane have not been established.

Tabulated list of adverse reactions.

The following adverse reactions are classified according to the following convention: very common (≥ 1/10), common (≥ 1/100 to < 1/10), uncommon (≥ 1/1,000 to < 1/100), rare (≥ 1/10,000 to < 1/1,000), very rare (< 1/10,000), or not known (cannot be estimated from available data). Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness. See Table 1.

Post marketing.

Post-marketing experience with topical NSAIDs suggests that patients with complicated ocular surgeries, corneal denervation, corneal epithelial defects, diabetes mellitus, ocular surface diseases (e.g. dry eye syndrome), rheumatoid arthritis or repeat ocular surgeries within a short period of time may be at increased risk for corneal adverse reactions which may become sight threatening.
Additional adverse events have been observed in post marketing experience with the use of nepafenac 1 mg/mL eye drops, suspension and may be observed with the use of Ilevro.

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration of the medicinal product is important. It allows continued monitoring of the benefit-risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions at www.tga.gov.au/reporting-problems.

4.9 Overdose

A topical overdose of Ilevro may be flushed from the eye(s) with warm tap water. There is no experience of overdose by the ophthalmic route. The application of more than one drop per eye is unlikely to lead to unwanted side-effects.
A bottle of Ilevro contains 9 mg of nepafenac (3 mg/mL). In a clinical study in which subjects received a single 10 mg oral administration of 14C-nepafenac, no safety concerns based upon a review of adverse events and an assessment of clinical laboratory, cardiovascular and general physical examination parameters were evident. In an acute toxicity study in mice no signs of toxicity were observed after oral administration of nepafenac up to 2000 mg/kg dose (~4400, and ~13,000 times the potential full bottle dose in a child and adult respectively) and in an acute toxicity study in rats, animals administered orally with nepafenac at a dose of 100 mg/kg, kg (~220, and ~660 times the potential full bottle dose in a child and adult respectively), survived the observation period of 7 days, swollen abdomens, red exudates on face, little or no stool and less active behavior was seen. Therefore, an oral overdose of Ilevro is unlikely to result in significant toxicity. However there is no data of the effects of oral overdose in young children or the elderly.

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

Nepafenac is a non-steroidal, anti-inflammatory and analgesic drug. After topical ocular dosing, nepafenac penetrates the cornea and is converted by ocular tissue hydrolases to amfenac, which is a non-steroidal, anti-inflammatory metabolite. Nepafenac and amfenac inhibit the action of prostaglandin H synthase (cyclooxygenase), an enzyme required for prostaglandin production.
In rabbits, nepafenac has been shown to inhibit blood-retinal-barrier breakdown, concomitant with suppression of PGE2 synthesis. In rabbits, a single topical ocular dose of nepafenac was shown to inhibit prostaglandin synthesis in the iris/ ciliary body by up to 89% with inhibition of 36% still present after 30 hours. Ex vivo, PGE2 synthesis in the retina/ choroid was inhibited by 38-50% for up to 80 minutes post-dose.
In rabbits, the rate of hydrolytic conversion of nepafenac to amfenac was highest in the retina/ choroid followed by the iris/ ciliary body and cornea. In human ocular tissues, the highest rate of hydrolytic conversion was in the iris/ ciliary body, with lower conversion rates observed in retina/ choroid and cornea.
Results from clinical studies indicate that Ilevro has no significant effect on intraocular pressure.

Clinical trials.

Postoperative pain and inflammation. The efficacy and safety of Ilevro in the prevention and treatment of postoperative pain and inflammation associated with cataract surgery has been demonstrated in two masked, double blind, placebo-controlled clinical trials in which a total of 3462 patients were randomized. Of these, 1339 patients received at least one dose of nepafenac 0.3%. In these studies in which patients were dosed daily beginning one day prior to cataract surgery, continued on the day of surgery and for the first 14 days of the postoperative period, Ilevro demonstrated superior clinical efficacy compared to its vehicle in treating postoperative pain and inflammation.
Both studies enrolled patients requiring cataract surgery by phacoemulsification and implantation of a posterior chamber intraocular lens. Patients had no baseline inflammation and did not receive any anti-inflammatory medication other than the assigned therapy. Patients with a history of chronic or recurrent inflammatory eye diseases and patients at increased risk of developing postoperative macular oedema (e.g. diabetic retinopathy patients) in the operative eye were excluded from the study.
Patients treated with Ilevro were less likely to have ocular pain and measurable signs of inflammation (aqueous cells and flare) in the early postoperative period through to the end of treatment than those treated with its vehicle. In the two studies, Ilevro cleared inflammation at day 14 postoperation in 65% and 68% of patients compared to 25% and 35% of patients on vehicle. Pain free rates in the Ilevro group were 89% and 91% compared to 40% and 50% of patients on vehicle. The day 14 results for reduction of both pain and inflammation were statistically significantly superior to the vehicle.
Reduction in the risk of postoperative macular oedema associated with cataract surgery in diabetic patients with non proliferative diabetic retinopathy. Two studies in patients with non proliferative diabetic retinopathy were conducted to assess the efficacy and safety of Ilevro eye drops, suspension dosed once a day for the prevention of postoperative macular oedema associated with cataract surgery.

Clinical study treatment regimen.

In these studies, patients were randomized to Ilevro or Vehicle and had the study drug instilled topically into the eye once daily from Day-1 (the day prior to surgery) through Day 90 (or Early Exit). Separate from the aforementioned study drug administration, subjects also received 1 drop of study drug 30 to 120 minutes prior to the scheduled cataract surgery on Day 0. Regardless of treatment group assignment, all subjects also instilled prednisolone eye drops for 4 weeks postsurgery (4 times daily in the study eye for 2 weeks postsurgery followed by 2 times daily in the study eye for the subsequent 2 weeks postsurgery), beginning with the first postsurgical dosing time point.

Major exclusion criteria.

The following specific conditions excluded subjects from participation in the study based on increased background risk of macular oedema: (1) pre-existing macular oedema in the study eye (2) signs of vitreomacular traction or epiretinal membrane.

Efficacy results.

In both double-masked, randomised vehicle-controlled studies, conducted in patients with non proliferative diabetic retinopathy, a significantly greater percentage of patients in the vehicle group developed macular oedema (17.3% and 14.3%) compared to patients treated with Ilevro (2.3% and 5.9%). The corresponding percentages in integrated analysis of the 2 studies were 15.9% in vehicle group and 4.1% in Ilevro group, p < 0.001). A significantly greater percentage of patients achieved improvement of 15 or more letters at Day 14 and maintained the improvement through Day 90 in Ilevro group (61.7%) compared to vehicle group (43%) in one study; the percentage of subjects was not statistically significant in the 2 treatment groups for this endpoint in the second study (48.8% in Ilevro group and 50.5% in vehicle group). In integrated analysis of the 2 studies, the percentage of subjects with 15 letter improvement at Day 14 and maintained to Day 90 was higher in Ilevro group (55.4%) compared to vehicle group (46.7%, p = 0.003).

5.2 Pharmacokinetic Properties

Absorption.

Following one drop of Ilevro in both eyes once daily for four days, low but quantifiable plasma concentrations of nepafenac and amfenac were observed in the majority of subjects 2 and 3 hours post-dose, respectively. The mean steady-state plasma Cmax for nepafenac and for amfenac were 0.847 ± 0.269 nanogram/mL and 1.13 ± 0.491 nanogram/mL, respectively, following ocular administration.

Distribution.

Amfenac has a high affinity towards serum albumin proteins. In vitro, the percentages of amfenac bound to rat albumin, human albumin and human serum are 98.4%, 95.4% and 99.1%, respectively. The binding percentages of nepafenac to plasma proteins for rat, monkey and human are 72.8%, 79.8% and 83.5%, respectively.
Studies in rats have shown that radioactive labelled active substance-related materials distribute widely in the body following single and multiple oral doses of 14C-nepafenac.
Studies in rabbits demonstrated that the topically administered nepafenac is distributed locally from the front of the eye to the posterior segments of the eye (retina and choroid).

Metabolism.

Nepafenac undergoes relatively rapid bioactivation to amfenac via intraocular hydrolases.
Subsequently, amfenac undergoes extensive metabolism to more polar metabolites involving hydroxylation of the aromatic ring leading to glucuronide conjugate formation.
Radiochromatographic analyses before and after β-glucuronidase hydrolysis indicated that all metabolites were in the form of glucuronide conjugates, with the exception of amfenac. Amfenac was the major metabolite in plasma, representing approximately 13% of total plasma radioactivity. The second most abundant plasma metabolite was identified as 5-hydroxynepafenac, representing approximately 9% of total radioactivity at Cmax.
Metabolite profiles of radioactivity in rabbit ocular tissues following a topical dose of 0.3% 14C-AL-6516 showed only AL-6516, AL-6295 and a minor unidentified metabolite.

Excretion.

After oral administration of 14C-nepafenac to healthy volunteers, urinary excretion was found to be the major route of radioactive excretions, accounting for approximately 85% while faecal excretion represented approximately 6% of the dose.

5.3 Preclinical Safety Data

Genotoxicity.

Nepafenac was not mutagenic in bacteria or mammalian cells, but induced chromosomal aberrations in vitro in Chinese hamster ovary cells at concentrations that had precipitate. Nepafenac was not clastogenic in mice in vivo, even at very high oral doses (5000 mg/kg). The weight of evidence indicates a low genotoxic potential for nepafenac.

Carcinogenicity.

Nepafenac has not been evaluated in long-term carcinogenicity studies.
