Nevanac Drug Information
Generic name: NEPAFENAC
Nonsteroidal Anti-inflammatory Drug [EPC]
Uses of Nevanac
® 0.1% is indicated for the treatment of pain and inflammation associated with cataract surgery. NEVANAC is a nonsteroidal, anti-inflammatory prodrug indicated for the treatment of pain and inflammation associated with cataract surgery.
Dosage & Administration of Nevanac
Recommended Dosing One drop of
NEVANAC 0.1% should be applied to the affected eye three times daily beginning 1 day prior to cataract surgery, continued on the day of surgery and through the first 2 weeks of the postoperative period. Shake the container well prior to dosing.
Use With Other Topical Ophthalmic Medications
NEVANAC 0.1% may be administered in conjunction with other topical ophthalmic medications, such as beta-blockers, carbonic anhydrase inhibitors, alpha-agonists, cycloplegics, and mydriatics. If more than one topical ophthalmic medication is being used, the medicines must be administered at least 5 minutes apart.
Side Effects of Nevanac
Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to the rates in the clinical trials of another drug and may not reflect the rates observed in practice. The most frequently reported ocular adverse reactions following cataract surgery were capsular opacity, decreased visual acuity, foreign body sensation, increased intraocular pressure (IOP), and sticky sensation. These reactions occurred in approximately 5% to 10% of patients.
Other ocular adverse reactions occurring at an incidence of approximately 1% to 5% included conjunctival edema, corneal edema, dry eye, lid margin crusting, ocular discomfort, ocular hyperemia, ocular pain, ocular pruritus, photophobia, tearing, and vitreous detachment. Some of these reactions may be the consequence of the cataract surgical procedure. Non-ocular adverse reactions reported at an incidence of 1% to 4% included headache, hypertension, nausea/vomiting, and sinusitis.
Warnings & Cautions for Nevanac
Increased Bleeding Time With some
NSAIDs, including NEVANAC 0.1%, there exists the potential for increased bleeding time due to interference with thrombocyte aggregation. There have been reports that ocularly applied NSAIDs may cause increased bleeding of ocular tissues (including hyphema) in conjunction with ocular surgery. It is recommended that NEVANAC 0.1% be used with caution in patients with known bleeding tendencies, or who are receiving other medications, which may prolong bleeding time.
Delayed Healing Topical
NSAIDs, including NEVANAC 0.1%, 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.
Corneal 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 topical NSAIDs, including NEVANAC 0.1%, and should be closely monitored for corneal health. Postmarketing 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 events, which may become sight threatening. Topical NSAIDs should be used with caution in these patients.
Postmarketing experience with topical NSAIDs also suggests that use more than 1 day prior to surgery or use beyond 14 days post-surgery may increase patient risk and severity of corneal adverse events.
Contact Lens Wear
NEVANAC ® 0.1% should not be administered while using contact lenses.
Pregnancy Safety for Nevanac
Pregnancy Teratogenic Effects Pregnancy Category C: Reproduction studies performed with nepafenac in rabbits and rats at oral doses up to 10 mg/kg/day have revealed no evidence of teratogenicity due to nepafenac, despite the induction of maternal toxicity. At this dose, the animal plasma exposure to nepafenac and amfenac was approximately 260 and 2400 times human plasma exposure at the recommended human topical ophthalmic dose for rats and 80 and 680 times human plasma exposure for rabbits, respectively. In rats, maternally toxic doses greater than or equal to 10 mg/kg were associated with dystocia, increased post-implantation loss, reduced fetal weights and growth, and reduced fetal survival.
Nepafenac has been shown to cross the placental barrier in rats. There are no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, NEVANAC 0.1% should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Non-Teratogenic Effects Because of the known effects of prostaglandin biosynthesis inhibiting drugs on the fetal cardiovascular system (closure of the ductus arteriosus), the use of NEVANAC 0.1% during late pregnancy should be avoided.
Pediatric Use of Nevanac
Pediatric Use The safety and effectiveness of NEVANAC 0.1% in pediatric patients below the age of 10 years have not been established.
Contraindications for Nevanac
0.1% is contraindicated in patients with previously demonstrated hypersensitivity to any of the ingredients in the formula or to other non-steroidal anti-inflammatory drugs (NSAIDs). Hypersensitivity to any of the ingredients in the formula or to other non-steroidal anti-inflammatory drugs (NSAIDS).
Clinical Studies of Nevanac
In two double-masked, randomized clinical trials in which patients were dosed 3 times daily beginning 1 day prior to cataract surgery, continued on the day of surgery and for the first 2 weeks of the postoperative period, NEVANAC 0.1% demonstrated superior clinical efficacy compared to its vehicle in treating postoperative pain and inflammation. Patients treated with NEVANAC ® 0.1% were less likely to have ocular pain and measurable signs of inflammation (cells and flare) in the early postoperative period through the end of treatment than those treated with its vehicle. For ocular pain in both studies, a significantly higher percentage of patients (approximately 80%) in the nepafenac group reported no ocular pain on the day following cataract surgery (Day 1) compared to those in the vehicle group (approximately 50%). Results from clinical studies indicated that NEVANAC 0.1% has no significant effect upon IOP; however, changes in IOP may occur following cataract surgery.
