Description
11 DESCRIPTION Latanoprost is a prostaglandin F 2α analogue. Its chemical name is isopropyl-(Z)-7[(1R,2R,3R,5S)3,5dihydroxy-2-[(3R)-3-hydroxy-5-phenylpentyl]cyclopentyl]-5-heptenoate. Its molecular formula is C 26 H 40 O 5 and its chemical structure is: Latanoprost is a colorless to yellow oil that is very soluble in acetonitrile and freely soluble in ethanol, ethyl acetate, and methanol. It is practically insoluble in water and hexanes. IYUZEH (latanoprost ophthalmic solution) 0.005% is supplied as a sterile, isotonic, aqueous solution of latanoprost with a pH of approximately 7 and an osmolality of approximately 280 mOsmol/kg. Each mL of IYUZEH contains 50 mcg of latanoprost. The inactive ingredients are: polyoxyl 40 hydrogenated castor oil, sorbitol, carbomer 974P, polyethylene glycol 4000, disodium edetate, sodium hydroxide (for pH-adjustment) and water for injections. One drop contains approximately 1.5 mcg of latanoprost. IYUZEH does not contain a preservative. chemstructure
What Is Latanoprost Ophthalmic Solution 0.005% Used For?
1 INDICATIONS AND USAGE IYUZEH ™ (latanoprost ophthalmic solution) 0.005% is indicated for the reduction of elevated intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension. IYUZEH is a prostaglandin F2α analogue indicated for the reduction of elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension. ( 1 )
Dosage and Administration
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 IYUZEH should not exceed once daily; the combined use of two or more prostaglandins, or prostaglandin analogs including IYUZEH 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. Reduction of the IOP starts approximately 3 to 4 hours after administration and the maximum effect is reached after 8 to 12 hours. IYUZEH may be used concomitantly with other topical ophthalmic drug products to lower IOP. In vitro studies have shown that precipitation occurs when eye drops containing thimerosal are mixed with the preserved 0.005% latanoprost reference product. 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 IYUZEH and may be reinserted 15 minutes after administration. The solution from one individual unit is to be used immediately after opening for administration to one or both eyes. Since sterility cannot be maintained after the individual unit is opened, the remaining contents should be discarded immediately after administration. One drop in the affected eye(s) once daily in the evening. ( 2 )
Side Effects (Adverse Reactions)
6 ADVERSE REACTIONS The following adverse reactions have been reported with the use of topical latanoprost products 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 (5% to 35%) for IYUZEH are: conjunctival hyperemia, eye irritation, eye pruritus, abnormal sensation in eye, foreign body sensation in eyes, vision blurred and lacrimation increased.

Revised: 03/2024 6.1 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 rates in the clinical trials of another drug and may not reflect the rates observed in practice. In the two clinical trials conducted with IYUZEH (latanoprost ophthalmic solution) 0.005% comparing it to XALATAN the preserved 0.005% latanoprost reference product, the most frequently reported ocular adverse reactions were conjunctival hyperemia and eye irritation ( Table 1 ).

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The reactions, which have been chosen for inclusion due to either their seriousness, frequency of reporting, possible causal connection to ophthalmic latanoprost products, or a combination of these factors, include: Nervous System Disorders: Dizziness; headache; toxic epidermal necrolysis Eye Disorders: Eyelash and vellus hair changes of the eyelid (increased length, thickness, pigmentation, and number of eyelashes); keratitis; corneal edema and erosions; intraocular inflammation (iritis/uveitis); macular edema, including cystoid macular edema; trichiasis; periorbital and lid changes resulting in deepening of the eyelid sulcus; iris cyst; eyelid skin darkening; localized skin reaction on the eyelids; conjunctivitis; pseudopemphigoid of the ocular conjunctiva. Respiratory, Thoracic and Mediastinal Disorders: Asthma and exacerbation of asthma; dyspnea Gastrointesting Disorders: Nausea; vomiting Skin and Subcutaneous Tissue Disorders: Pruritis Infections and Infestations: Herpes keratitis Cardiac Disorders: Angina; palpitations; angina unstable General Disorders and Administration Site Conditions: Chest pain

Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary There are no adequate and well-controlled studies of IYUZEH administration in pregnant women to inform drug-associated risks. In animal reproduction studies, intravenous (IV) administration of latanoprost to pregnant rabbits and rats throughout the period of organogenesis produced malformations, embryofetal lethality and spontaneous abortion at clinically relevant doses (equivalent to 1.3 – 324 times the maximum recommended human ophthalmic dose, on a mg/m 2 basis, assuming 100% absorption) (see Data ) . The background risk of major birth defects and miscarriage for the indicated population is unknown. However, the background risk in the U.S. general population of major birth defects is 2 to 4%, and of miscarriage is 15 to 20% of clinically recognized pregnancies. Data Animal Data Embryofetal studies were conducted in pregnant rabbits administered latanoprost daily by IV injection on gestation days 6 through 18, to target the period of organogenesis. A no observed adverse effect level (NOAEL) was not established for rabbit developmental toxicity. Post-implantation loss due to late resorption was shown as doses ≥0.2 mcg/kg/day (equivalent to 1.3 times the maximum recommended human ophthalmic dose [RHOD], on a mg/m 2 basis, assuming 100% absorption). Spina bifida and abortion occurred at 5 mcg/kg/day (equivalent to 32 times the maximum RHOD). Total litter loss due to early resorption was observed at doses ≥50 mcg/kg/day (324 times the maximum RHOD). Transient signs of maternal toxicity were observed after IV dosing (increased breathing, muscle tremors, slight motor incoordination) at 300 mcg/kg/day (1946 times the maximum RHOD). No maternal toxicity was observed at doses up to 50 mcg/kg/day. Embryofetal studies were conducted in pregnant rats administered latanoprost daily by IV injection on gestation days 6 through 15, to target the period of organogenesis. A NOAEL for rat developmental toxicity was not established. Cleft palate was...
Overdosage
10 OVERDOSAGE Intravenous infusion of up to 3 mcg/kg of latanoprost in healthy volunteers produced mean plasma concentrations 200 times higher than during clinical treatment with latanoprost ophthalmic solution and no adverse reactions were observed. IV dosages of 5.5 to 10 mcg/kg caused abdominal pain, dizziness, fatigue, hot flushes, nausea, and sweating.
