Latoprost Eye Drop is a prostaglandin analogue used to lower intraocular pressure (IOP) in patients with open-angle glaucoma and ocular hypertension. It works by enhancing the outflow of aqueous humor from the eye, thereby reducing pressure and helping to prevent optic nerve damage and vision loss.

How does Latoprost Eye Drop work?
- Enhances aqueous humor outflow: Latoprost binds to prostaglandin F2α receptors, increasing uveoscleral outflow from the eye.
- Reduces intraocular pressure (IOP):Â Decreases fluid buildup inside the eye, preventing optic nerve damage and vision loss.
- Relaxes trabecular meshwork: Improves natural drainage of eye fluid for pressure control.
Dosage
- Apply one drop in the affected eye(s) daily in the evening or as prescribed by your ophthalmologist.
- If a dose is missed, apply as soon as remembered unless near the next scheduled dose.
- Do not exceed the prescribed frequency—overuse may reduce effectiveness.
Uses
- Treatment of open-angle glaucoma.
- Reduction of elevated intraocular pressure in ocular hypertension.
- Prevention of optic nerve damage associated with chronic high IOP.
Side Effects
- Eye redness or irritation
- Blurred vision
- Dry eyes or discomfort
- Excessive eyelash growth
- Iris pigmentation changes
- Eye pain or headache
- Dizziness or flu-like symptoms
- Rare: Macular edema or eyelash changes
Interactions
- Other eye drops:Â Maintain at least 5 minutes gap between Latoprost and any other ophthalmic medication.
- Contact lenses: Remove lenses before use and reinsert only after 15 minutes.
Pharmacokinetics
Latoprost is hydrolyzed in the cornea to its active acid form, showing minimal systemic absorption. It is primarily eliminated via the kidneys, ensuring localized ocular action with minimal systemic effects.
Clinical Trial Evidence
- Efficacy:Â Proven to significantly lower intraocular pressure in glaucoma and ocular hypertension patients, comparable or superior to timolol in long-term studies.
- Safety:Â Generally well tolerated, with most side effects mild and transient.
- Long-term use: Demonstrated sustained effectiveness in maintaining reduced IOP over extended treatment durations.
Precautions
- Use cautiously in patients with active eye infections.
- Monitor those with a history of macular edema or uveitis.
- Regularly check for changes in iris pigmentation during long-term therapy.
- Pregnant or breastfeeding women should use only under medical supervision.
Conclusion
Latoprost Eye Drop is an effective and well-tolerated treatment for open-angle glaucoma and ocular hypertension. By improving aqueous humor outflow and reducing intraocular pressure, it helps prevent optic nerve damage and preserve vision. Adherence to prescribed dosage and regular ophthalmic monitoring are essential for safe and optimal results.
