Overdosage of latanoprost
Information about signs, symptoms, and laboratory findings of acute ovedosage and the general principles of overdose treatment.10 OVERDOSAGE Intravenous infusion of up to 3 mcg/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 mcg/kg caused abdominal pain, dizziness, fatigue, hot flushes, nausea, and sweating. If overdosage with latanoprost occurs, treatment should be symptomatic.
Adverse reactions
Information about undesirable effects, reasonably associated with use of the drug, that may occur as part of the pharmacological action of the drug or may be unpredictable in its occurrence. Adverse reactions include those that occur with the drug, and if applicable, with drugs in the same pharmacologically active and chemically related class. There is considerable variation in the listing of adverse reactions. They may be categorized by organ system, by severity of reaction, by frequency, by toxicological mechanism, or by a combination of these.6 ADVERSE REACTIONS The following adverse reactions were reported in postmarketing experience and are discussed in greater detail in other sections of the label: Iris pigmentation changes [ see Warnings and Precautions (5.1) ] Eyelid skin darkening [ see Warnings and Precautions (5.1) ] Eyelash changes (increased length, thickness, pigmentation, and number of lashes) [ see Warnings and Precautions (5.2) ] Intraocular inflammation (iritis/uveitis) [ see Warnings and Precautions (5.3) ] Macular edema, including cystoid macular edema [ see Warnings and Precautions (5.4) ] Most common adverse reactions (≥4%) from clinical trials are blurred vision, burning and stinging, conjunctival hyperemia, foreign body sensation, itching, increased pigmentation of the iris, punctate epithelial keratopathy, and upper respiratory tract infection/cold/flu. ( 6 ). To report SUSPECTED ADVERSE REACTIONS, contact Bausch + Lomb, a division of Valeant Pharmaceuticals North America LLC at 1-800-321-4576 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, the adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Latanoprost was studied in three multicenter, randomized, controlled clinical trials. Patients received 50 mcg/mL latanoprost once daily or 5 mg/mL active-comparator (timolol) twice daily. The patient population studied had a mean age of 65 + 10 years. Seven percent of patients withdrew before the 6-month endpoint. Table 1: Ocular Adverse Reactions and ocular signs/symptoms reported by 5–15% of patients receiving Latanoprost Symptom/Finding Adverse Reactions (incidence (%)) Latanoprost (n=460) Timolol (n=369) Foreign body sensation 13 8 Punctate epithelial keratopathy 10 9 Stinging 9 12 Conjunctival hyperemia 8 3 Blurred vision 8 8 Itching 8 8 Burning 7 8 Increased pigmentation of the iris 7 0 Less than 1% of the patients treated with latanoprost required discontinuation of therapy because of intolerance to conjunctival hyperemia. Table 2: Adverse Reactions that were reported in 1–5% of patients receiving Latanoprost Adverse Reactions (incidence (%)) Latanoprost (n=460) Timolol (n=369) Ocular Events/Signs and Symptoms Excessive tearing 4 6 Lid discomfort/pain 4 2 Dry eye 3 3 Eye pain 3 3 Lid crusting 3 3 Lid erythema 3 2 Photophobia 2 1 Lid edema 1 3 Systemic Events Upper respiratory tract infection/cold/flu 3 3 Muscle/joint/back pain 1 0.5 Rash/allergic skin reaction 1 0.3 6.2 Postmarketing Experience The following reactions have been identified during postmarketing use of latanoprost in clinical practice. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. The reactions, which have been chosen for inclusion due to either their seriousness, frequency of reporting, possible causal connection to latanoprost, or a combination of these factors, include: Nervous System disorders: dizziness, headache, and toxic epidermal necrolysis Eye Disorders: eyelash and vellus hair changes (increased length, thickness, pigmentation, and number); keratitis; corneal edema and erosions; intraocular inflammation (iritis/uveitis); macular edema, including cystoid macular edema; misdirected eyelashes sometimes resulting in eye irritation; periorbital and lid changes resulting in deepening of the eyelid sulcus. Respiratory, Thoracic and Mediastinal Disorders: asthma and exacerbation of asthma; dyspnea Skin and Subcutaneous Tissue Disorders: eyelid skin darkening Infections and Infestations: Herpes keratitis
latanoprost Drug Interactions
Information about and practical guidance on preventing clinically significant drug/drug and drug/food interactions that may occur in people taking the drug.7 DRUG INTERACTIONS In vitro studies have shown that precipitation occurs when eye drops containing thimerosal are mixed with latanoprost. If such drugs are used, they should be administered at least five (5) minutes apart. The combined use of two or more prostaglandins, or prostaglandin analogs including latanoprost is not recommended. It has been shown that administration of these prostaglandin drug products more than once daily may decrease the IOP lowering effect or cause paradoxical elevations in IOP. In vitro studies have shown that precipitation occurs when eye drops containing thimerosal are mixed with Latanoprost. If such drugs are used, they should be administered at least 5 minutes apart.

Clinical pharmacology
Information about the clinical pharmacology and actions of the drug in humans.12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Latanoprost is a prostanoid selective FP receptor agonist that is believed to reduce the intraocular pressure (IOP) by increasing the outflow of aqueous humor. Studies in animals and man suggest that the main mechanism of action is increased uveoscleral outflow. Elevated IOP represents a major risk factor for glaucomatous field loss. The higher the level of IOP, the greater the likelihood of optic nerve damage and visual field loss. 12.2 Pharmacodynamics Reduction of the IOP in man starts about 3-4 hours after administration and maximum effect is reached after 8-12 hours. IOP reduction is present for at least 24 hours. 12.3 Pharmacokinetics Absorption Latanoprost is absorbed through the cornea where the isopropyl ester prodrug is hydrolyzed to the acid form to become biologically active. Distribution The distribution volume in humans is 0.16 + 0.02 L/kg. The acid of latanoprost can be measured in aqueous humor during the first 4 hours, and in plasma only during the first hour after local administration. Studies in man indicate that the peak concentration in the aqueous humor is reached about two hours after topical administration. Metabolism Latanoprost, an isopropyl ester prodrug, is hydrolyzed by esterases in the cornea to the biologically active acid. The active acid of latanoprost reaching the systemic circulation is primarily metabolized by the liver to the 1,2-dinor and 1,2,3,4-tetranor metabolites via fatty acid β-oxidation. Excretion The elimination of the acid of latanoprost from human plasma is rapid (t 1/2 = 17 min) after both intravenous and topical administration. Systemic clearance is approximately 7 mL/min/kg. Following hepatic β-oxidation, the metabolites are mainly eliminated via the kidneys. Approximately 88% and 98% of the administered dose are recovered in the urine after topical and intravenous dosing, respectively.

Dosage and administration
Information about the drug product’s dosage and administration recommendations, including starting dose, dose range, titration regimens, and any other clinically sigificant information that affects dosing recommendations.2 DOSAGE AND ADMINISTRATION The recommended dosage is one drop in the affected eye(s) once daily in the evening. If one dose is missed, treatment should continue with the next dose as normal. The dosage of latanoprost ophthalmic solution should not exceed once daily; the combined use of two or more prostaglandins, or prostaglandin analogs including latanoprost is not recommended. It has been shown that administration of these prostaglandin drug products more than once daily may decrease the intraocular pressure (IOP) lowering effect or cause paradoxical elevations in IOP. Reduction of the IOP starts approximately 3 to 4 hours after administration and the maximum effect is reached after 8 to 12 hours. Latanoprost ophthalmic solution may be used concomitantly with other topical ophthalmic drug products to lower IOP. If more than one topical ophthalmic drug is being used, the drugs should be administered at least five (5) minutes apart. Contact lenses should be removed prior to the administration of latanoprost ophthalmic solution, and may be reinserted 15 minutes after administration. One drop in the affected eye(s) once daily in the evening. ( 2 )

latanoprost: Information for patients
Information necessary for patients to use the drug safely and effectively, such as precautions concerning driving or the concomitant use of other substances that may have harmful additive effects.17 PATIENT COUNSELING INFORMATION 17.1 Potential for Pigmentation Advise patients about the potential for increased brown pigmentation of the iris, which may be permanent. Inform patients about the possibility of eyelid skin darkening, which may be reversible after discontinuation of Latanoprost ophthalmic solution [ see Warnings and Precautions (5.1) ]. 17.2 Potential for Eyelash Changes Inform patients of the possibility of eyelash and vellus hair changes in the treated eye during treatment with Latanoprost ophthalmic solution. These changes may result in a disparity between eyes in length, thickness, pigmentation, number of eyelashes or vellus hairs, and/or direction of eyelash growth. Eyelash changes are usually reversible upon discontinuation of treatment. 17.3 Handling the Container Instruct patients 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 [ see Warnings and Precautions (5.6) ]. 17.4 When to Seek Physician Advice Advise patients that if they develop an intercurrent ocular condition (e.g., trauma or infection) or have ocular surgery, or develop any ocular reactions, particularly conjunctivitis and eyelid reactions, they should immediately seek their physician’s advice concerning the continued use of the multiple-dose container. 17.5 Use with Contact Lenses Advise patients that Latanoprost ophthalmic solution contains benzalkonium chloride, which may be absorbed by contact lenses. Contact lenses should be removed prior to administration of the solution. Lenses may be reinserted 15 minutes following administration of Latanoprost ophthalmic solution. 17.6 Use with Other Ophthalmic Drugs If more than one topical ophthalmic drug is being used, the drugs should be administered at least five (5) minutes apart.

Clinical studies
This field may contain references to clinical studies in place of detailed discussion in other sections of the labeling.14 CLINICAL STUDIES 14.1 Elevated Baseline IOP Patients with mean baseline IOP of 24-25 mmHg who were treated for 6 months in multi-center, randomized, controlled trials demonstrated 6-8 mmHg reductions in IOP. This IOP reduction with latanoprost 0.005% dosed once daily was equivalent to the effect of timolol 0.5% dosed twice daily. 14.2 Progression of Increased Iris Pigmentation A 3-year open-label, prospective safety study with a 2-year extension phase was conducted to evaluate the progression of increased iris pigmentation with continuous use of latanoprost once-daily as adjunctive therapy in 519 patients with open-angle glaucoma. The analysis was based on observed-cases population of the 380 patients who continued in the extension phase. Results showed that the onset of noticeable increased iris pigmentation occurred within the first year of treatment for the majority of the patients who developed noticeable increased iris pigmentation. Patients continued to show signs of increasing iris pigmentation throughout the five years of the study. Observation of increased iris pigmentation did not affect the incidence, nature, or severity of adverse events (other than increased iris pigmentation) recorded in the study. IOP reduction was similar regardless of the development of increased iris pigmentation during the study.
