`
`Excretion: The elimination of the acid of latanoprost from human plasma was rapid (t1/,=17 min) after
`both intravenous and topical administration. Systemic clearance is approximately
`7 mL/min/kg. Following hepatic B-oxidation, the metabolites are mainly eliminated via the kidneys.
`Approximately 88% and 98% ofthe administered dose is recovered in the urine after topical and
`intravenous dosing, respectively.
`
`Animal Studies
`
`In monkeys, latanoprost has been shown to induce increased pigmentation of the iris. The results from
`the preclinical program demonstrated that the increased pigmentation is unlikely to be associated with
`proliferation of melanocytes. It appears that the mechanism of increased pigmentation is stimulation of
`melanin production in melanocytes ofthe iris stroma.
`
`In ocular toxicity studies, administration of latanoprost at a dose of 6ag/eye/day (4 times the daily
`human dose) to cynomolgus monkeys has also been shown to induce increased palpebral fissure. This
`effect is reversible and occurs at doses above the standard clinical dose level.
`
`INDICATIONS AND USAGE
`
`XALATAN Sterile Ophthalmic Solution is indicated for the reduction of elevated intraocular pressure
`in patients with open-angle glaucoma and ocular hypertension who are intolerant of other intraocular
`pressure lowering medications or insufficiently responsive (failed to achieve target lOP determined after
`multiple measurements over time) to another intraocular pressure lowering medication.
`
`CLINICAL STUDIES
`
`Patients with mean baseline intraocular pressure of 24-25 mmHg who were treated for 6 months in
`multi—center, randomized, controlled trials demonstrated 6-8 mmHg reductions in intraocular pressure.
`This lOP reduction with XALATAN Sterile Ophthalmic Solution 0.005% dosed once daily was
`equivalent to the effect oftimolol 0.5% dosed twice daily.
`
`CONTRAINDICATIONS
`
`Known hypersensitivity to latanoprost, benzalkonium chloride or any other ingredients in this product.
`
`WARNINGS
`
`XALATAN has been reported to cause changes to pigmented tissues. The most frequently
`reported changes have been increased pigmentation of the iris and periorbital tissue (eyelid) and
`increased pigmentation and growth of eyelashes. These changes may be permanent.
`
`XALATAN Sterile Ophthalmic Solution may gradually change eye color, increasing the amount of
`brown pigment in the iris by increasing the number of melanosomes (pigment granules) in melanocytes.
`The long term effects on the melanocytes and the consequences of potential injury to the melanocytes
`and/or deposition of pigment granules to other areas ofthe eye are currently unknown. The change in
`iris color occurs slowly and may not be noticeable for several months to years. Patients should be
`informed ofthe possibility of iris color change.
`
`Eyelid skin darkening has also been reported in association with the use of XALATAN.
`
`XALATAN may gradually change eyelashes and vellus hair; these changes include increased length,

`
`thickness, pigmentation, and number of lashes or hairs, and misdirected growth of eyelashes.
`
`Patients who are expected to receive treatment in only one eye should be informed about the potential
`for increased brown pigmentation of the iris, periorbital tissue, and eyelashes in the treated eye and thus,
`heterochromia between the eyes. They should also be advised of the potential for a disparity between
`the eyes in length, thickness, and/or number of eyelashes. These changes in pigmentation and lash
`growth may be permanent.
`
`PRECAUTIONS
`
`General: Latanoprost is hydrolyzed in the cornea. The effect of continued administration of
`XALATAN Sterile Ophthalmic Solution on the corneal endothelium has not been fully evaluated.
`
`There have been reports of bacterial keratitis associated with the use of multiple-dose containers of
`topical ophthalmic products. These containers had been inadvertently contaminated by patients who, in
`most cases, had a concurrent corneal disease or a disruption of the ocular epithelial surface (See
`Information for Patients).
`
`Patients may slowly develop increased brown pigmentation ofthe iris. This change may not be
`noticeable for several months to years (see WARNINGS). Typically the brown pigmentation around
`the pupil spreads concentrically towards the periphery in affected eyes, but the entire iris or parts of it
`may also become more brownish. Until more information about increased brown pigmentation is
`available, patients should be examined regularly and, depending on the clinical situation, treatment may
`be stopped ifincreased pigmentation ensues. During clinical trials, the increase in brown iris pigment
`has not been shown to progress further upon discontinuation of treatment, but the resultant color change
`may be permanent. Neither nevi nor freckles 0f the iris have been affected by treatment.
`
`XALATAN should be used with caution in patients with active intraocular inflammation (iritis/uveitis).
`
`Macular edema, including cystoid macular edema, has been reported during treatment with XALATAN.
`These reports have mainly occurred in aphakic patients, in pseudophakic patients with a torn posterior
`lens capsule, or in patients with known risk factors for macular edema. XALATAN should be used with
`caution in these patients.
`
`There is limited experience with XALATAN in the treatment of angle closure, inflammatory or
`neovascular glaucoma.
`
`XALATAN has not been studied in patients with renal or hepatic impairment and should therefore be
`used with caution in such patients.
`
`XALATAN should not be administered while wearing contact lenses.
`
`Informationfor Patients (see WARNINGS): Patients should be informed about the possibility of iris
`color change due to an increase of the brown pigment and resultant cosmetically different eye coloration
`that may occur when only one eye is treated.
`lris pigmentation changes may be more noticeable in
`patients with green-brown, blue/gray-brown or yellow-brown irides.

`
`Patients should also be informed ofthe possibility of eyelash and vellus hair changes in the treated eye,
`which may result in a disparity between eyes in length, thickness, pigmentation, number of eyelashes or
`vellus hairs, and/or direction of eyelash growth.
`
`Patients should also be informed about the possibility of eyelid skin darkening.
`
`The increased pigmentation to the iris and eyelid, as well as the changes to the eyelashes, may be
`permanent.
`
`Patients should be instructed to avoid allowing the tip of the dispensing container to contact the eye or
`surrounding structures because this could cause the tip to become contaminated by common bacteria
`known to cause ocular infections. Serious damage to the eye and subsequent loss of vision may result
`from using contaminated solutions.
`
`Patients also should be advised that ifthey develop an intercurrent ocular condition (e.g., trauma or
`infection) or have ocular surgery, they should immediately seek their physician‘s advice concerning the
`continued use of the multidose container.
`
`Patients should be advised that if they develop any ocular reactions, particularly conjunctivitis and lid
`reactions, they should immediately seek their physician’s advice.
`
`Patients should also be advised that XALATAN contains benzalkonium chloride which may be
`absorbed by soft contact lenses. Contact lenses should be removed prior to administration of the
`solution. Lenses may be reinserted 15 minutes following administration of XALATAN.
`
`If more than one topical ophthalmic drug is being used, the drugs should be administered at least five
`(5) minutes apart.
`
`Drug Interactions: In vitro studies have shown that precipitation occurs when eye drops containing
`thimerosal are mixed with XALATAN. If such drugs are used they should be administered with an
`interval of at least five (5) minutes between applications.
`
`Carcinogenesis, Mutagenesis, Impairment ofFerti/ity:
`Latanoprost was not mutagenic in bacteria, in mouse lymphoma or in mouse micronucleus tests.
`
`Chromosome aberrations were observed in vitro with human lymphocytes.
`
`Latanoprost was not carcinogenic in either mice or rats when administered by oral gavage at doses of up
`to 170 ug/kg/day (approximately 2,800 times the recommended maximum human dose) for up to 20
`and 24 months. respectively.
`
`Additional in vitro and in vivo studies on unscheduled DNA synthesis in rats were negative.
`Latanoprost has not been found to have any effect on male or female fertility in animal studies.
`
`Pregnancy: Teratogenic Effects: Pregnancy Category C.
`Reproduction studies have been performed in rats and rabbits. In rabbits an incidence of 4 of 16 dams

`
`had no viable fetuses at a dose that was approximately 80 times the maximum human dose, and the
`highest nonembryocidal dose in rabbits was approximately 15 times the maximum human close. There
`are no adequate and well-controlled studies in pregnant women. XALATAN should be used during
`pregnancy only if the potential benefit justifies the potential risk to the fetus.
`
`It is not known whether this drug or its metabolites are excreted in human milk.
`Nursing Mothers:
`Because many drugs are excreted in human milk, caution should be exercised when XALATAN is
`administered to a nursing woman.
`
`Pediatric Use: Safety and effectiveness in pediatric patients have not been established.
`
`Geriatric Use: No overall differences in safety or effectiveness have been observed between elderly
`and younger patients.
`
`ADVERSE REACTIONS
`
`Adverse events referred to in other sections of this insert:
`
`Eyelash changes (increased length, thickness, pigmentation, and number oflashes); eyelid skin
`darkening; intraocular inflammation (iritis/uveitis); iris pigmentation changes; and macular edema,
`including cystoid macular edema (See WARNINGS and PRECAUTIONS).
`
`Controlled Clinical Trials:
`
`The ocular adverse events and ocular signs and symptoms reported in 5 to 15% of the patients on
`XALATAN Sterile Ophthalmic Solution in the 6-month, multi-center, double-masked, active—controlled
`trials were blurred vision, burning and stinging, conjunctiva] hyperemia, foreign body sensation,
`itching, increased pigmentation of the iris. and punctate epithelial keratopathy.
`
`Local conjunctiva] hyperemia was observed; however, less than 1% of the patients treated with
`XALATAN required discontinuation of therapy because of intolerance to conjunctiva] hyperemia.
`
`In addition to the above listed ocular events/signs and symptoms, the following were reported in 1 to
`4% ofthe patients: dry eye, excessive tearing, eye pain, lid crusting, lid discomfort/pain, lid edema, lid
`erythema, and photophobia.
`
`The following events were reported in less than 1% ofthe patients: conjunctivitis, diplopia and
`discharge from the eye.
`
`During clinical studies, there were extremely rare reports ofthe following: retina] artery embolus,
`retinal detachment, and vitreous hemorrhage from diabetic retinopathy.
`
`The most common systemic adverse events seen with XALATAN were upper respiratory tract
`infection/cold/flu which occurred at a rate of approximately 4%. Chest pain/angina pectoris,
`muscle/joint/back pain, and rash/allergic skin reaction each occurred at a rate of l to 2%.
`
`Clinical Practice: The following events have been identified during postmarketing use of XALATAN
`in clinical practice. Because they are reported voluntarily from a population of unknown size, estimates
`of frequency cannot be made. The events, which have been chosen for inclusion due to either their

`
`seriousness, frequency of reporting, possible causal connection to XALATAN, or a combination of
`these factors, include: asthma and exacerbation of asthma; corneal edema and erosions; dyspnea;
`eyelash and vellus hair changes (increased length, thickness, pigmentation, and number); eyelid skin
`darkening; herpes keratitis; intraocular inflammation (iritis/uveitis); keratitis; macular edema, including
`cystoid macular edema; misdirected eyelashes sometimes resulting in eye irritation; and toxic epidermal
`necrolysis.
`
`OVERDOSAGE
`
`Apart from ocular irritation and conjunctival or episcleral hyperemia, the ocular effects of latanoprost
`administered at high doses are not known. Intravenous administration of large doses of latanoprost in
`monkeys has been associated with transient bronchoconstriction; however, in l 1 patients with bronchial
`asthma treated with latanoprost, bronchoconstriction was not induced. Intravenous infusion of up to 3
`Mg/kg in healthy volunteers produced mean plasma concentrations 200 times higher than during clinical
`treatment and no adverse reactions were observed. Intravenous dosages of 5.5 to 10 ug/kg caused
`abdominal pain, dizziness, fatigue, hot flushes, nausea and sweating.
`
`If overdosage with XALATAN Sterile Ophthalmic Solution occurs, treatment should be symptomatic.
`
`DOSAGE AND ADMINISTRATION
`
`The recommended dosage is one drop (1.5 pig) in the affected eye(s) once daily in the evening.
`
`The dosage of XALATAN Sterile Ophthalmic Solution should not exceed once daily since it has been
`shown that more frequent administration may decrease the intraocular pressure lowering effect.
`
`Reduction of the intraocular pressure starts approximately 3 to 4 hours after administration and the
`maximum effect is reached after 8 to 12 hours.
`
`XALATAN may be used concomitantly with other topical ophthalmic drug products to lower
`intraocular pressure. If more than one topical ophthalmic drug is being used, the drugs should be
`administered at least five (5) minutes apart.
