Mechanism of Action
Xalatan Ophthalmic Solution 0.005% acts by increasing the outflow of aqueous humor from the anterior chamber of the eye to the sclera, thus reducing the intraocular pressure. It does this by increasing the activity of aqueous outflow pathways, like the trabecular meshwork and Schlemm's canal.How long does it take to work?
Xalatan Ophthalmic Solution 0.005% usually starts to work within a few hours after it is applied. However, it may take as long as three to four weeks before the full benefit of the drug is seen.Absorption, Route of elimination, Dosage, Administration
Xalatan Ophthalmic Solution 0.005% is absorbed through the conjunctiva and is metabolized in the liver by enzyme cytochrome P450. It is eliminated mainly through the urine and feces. The suggested dose for adults and children over 12 years of age is one drop in each affected eye daily, usually in the evening. For children under 12, the exact dosage should be prescribed by a doctor. Xalatan Ophthalmic Solution 0.005% should be administered as eye drops. To apply the drop, the user should start by washing their hands. The tip of the dropper should be gently placed to the eye and the solution should be released while the eye is closed. The medication should not be used more than once in a day.Side Effect
Xalatan Ophthalmic Solution 0.005% can cause side effects such as conjunctival hyperemia (redness of the eyes), burning sensation, blurred vision, dry eyes, cough, headache, nausea, and an increased amount of tears.Toxicity
Xalatan Ophthalmic Solution 0.005% is usually well tolerated, but may be toxic in cases of overdoses. Common symptoms of an overdose include headache, dizziness, nausea, vomiting, and difficulty breathing. If an overdose is suspected, the patient should be taken to the nearest hospital or poison control center immediately.Precautions
Xalatan Ophthalmic Solution 0.005% should be used with caution in patients who have severe allergic reactions, high blood pressure, and pterygium.It should also be used cautiously in patients with glaucoma caused by pseudoexfoliation or neovascularization.Interactions
There are no known drug interactions with latanoprost, but it may interact with other eye medications like ophthalmic beta blockers, carbonic anhydrase inhibitors, and miotics, so any current medications should be discussed with the doctor before use.Disease Interaction
Xalatan Ophthalmic Solution 0.005% may be toxic to those with severe viral, bacterial, or fungal infections affecting the eye. Severe narrow angle glaucoma, iritis, and cystoid macular edema may also present a risk.Drug Interaction
Xalatan Ophthalmic Solution 0.005% should not be used with drugs that lower intraocular pressure, like beta blockers or anticholinesterase drugs.Food Interactions
Foods that may interact with Xalatan Ophthalmic Solution 0.005% include salsalate, ascorbic acid, and sucralfate. Grapefruit may increase the absorption and concentration of latanoprost and should be avoided.Pregnancy Use
Xalatan Ophthalmic Solution 0.005% is not recommended for use during pregnancy. Animal studies have revealed evidence of embryo toxicity, so the benefits of use should be weighed against the potential risks.Lactation Use
It is not recommended for use during lactation as it is not known if latanoprost is present in breast milk and it could affect the baby.Acute Overdose

2. What is latanoprost used for?
It is used to treat:
3. How does latanoprost work?
It increases the outflow of aqueous humor (fluid in the eye) through the uveoscleral pathway, reducing intraocular pressure.
4. Is latanoprost a prescription drug?
Yes, it requires a prescription from a healthcare provider.
5. Who can use latanoprost?
It’s suitable for adults and some children with glaucoma or ocular hypertension, but not for those with certain eye conditions (e.g., uveitis) unless advised by a doctor.

The standard dose is one drop (0.005% solution) in the affected eye(s) once daily, preferably at night.
8. How long does latanoprost take to work?
It begins reducing eye pressure within 3-4 hours, with maximum effect in 8-12 hours.
9. Can latanoprost be used long-term?
Yes, it’s often used long-term to manage chronic conditions like glaucoma, under medical supervision.

It may cause temporary blurred vision after application but doesn’t typically harm vision long-term.
14. Can latanoprost be used with contact lenses?
Remove contact lenses before use and wait 15 minutes before reinserting, as the preservative (benzalkonium chloride) may affect lenses.
