Xalatan vs Travatan
Introduction
For patients with elevated intraocular pressure (IOP) or open-angle glaucoma, certain drugs are available that reduce the production of fluid in the eye or increase its outflow, thereby lowering IOP and helping to prevent vision loss. Xalatan and Travatan are two such medications often prescribed for these conditions. They both belong to a class of drugs known as prostaglandin analogs which work by increasing the outflow of aqueous humor - the fluid in the eye. Xalatan (latanoprost) is known to be highly effective at reducing IOP with once-daily dosing usually in evenings due to its 24-hour coverage period. On the other hand, Travatan (travoprost), while also a once-daily medication, may have an edge over latanoprost when it comes to patient tolerance and comfort because it contains a gentler preservative.
What is Xalatan?
Latanoprost (the generic name for Xalatan) was the first drug of the prostaglandin analog class of eye drops designed to treat glaucoma. Latanoprost got its approval from the FDA in 1996. Xalatan works by increasing the outflow of aqueous fluid from the eyes, effectively reducing intraocular pressure for prolonged periods. It is prescribed primarily for those suffering from open-angle glaucoma and ocular hypertension. The influence that Xalatan has on intraocular pressure is specifically targeted without major systemic side effects, resulting in it having fewer complications than other medications that can have more generalized effects.This makes it a preferred choice over Travoprost (Travatan), another prostaglandin analogue, which while similarly effective may cause longer eyelash growth and darkening of iris color in some patients as side-effects.
What conditions is Xalatan approved to treat?
Xalatan is approved for the treatment of certain types of glaucoma and other causes of high intraocular pressure (IOP):
- Open-angle glaucoma, which is the most common form
- Ocular hypertension, a condition that can lead to glaucoma if not controlled
- Pediatric glaucoma in children from birth to less than 18 years old.
How does Xalatan help with these illnesses?
Xalatan aids in managing glaucoma by increasing the drainage of fluid (aqueous humor) from inside the eye, thereby reducing intraocular pressure. It achieves this by mimicking a naturally occurring prostaglandin F2-alpha that has been shown to increase outflow of aqueous humor. High intraocular pressure is a major risk factor for optic nerve damage, an important cause of blindness associated with glaucoma. Travatan functions similarly as it also belongs to the class of drugs called prostaglandin analogs but contains different active ingredients. Both Xalatan and Travatan are effective at lowering raised eye pressure and can help prevent vision loss in people with open-angle glaucoma or ocular hypertension.
What is Travatan?
Travatan is a brand name for travoprost, which is a prostaglandin analog used in the treatment of glaucoma to lower intraocular pressure. Travoprost works by increasing the outflow of aqueous fluid from the eyes, thus reducing pressure. It was first approved by the FDA in 2001.
As Travatan isn't a beta-blocker like some other treatments for glaucoma, it does not reduce aqueous humor production but rather increases its outflow. This mechanism makes its side-effect profile different compared to beta-blockers such as Timolol—specifically, it's less likely to cause systemic side effects like low blood pressure and slowed heart rate (common with beta-blockers). The ability of Travatan to increase aqueous humor outflow can be beneficial for patients whose ocular hypertension or open-angle glaucoma doesn't respond well to typical beta-blocker treatments.
What conditions is Travatan approved to treat?
Travatan, a prostaglandin analogue like Xalatan, is recognized and approved for the treatment of:
- Open-angle glaucoma (OAG), which is characterized by an increase in pressure inside the eye that can lead to vision loss if left untreated.
- Ocular hypertension (OH), which refers to elevated intraocular pressure that may potentially result in glaucoma over time.
How does Travatan help with these illnesses?
Travatan, like Xalatan, is a prostaglandin analog. Prostaglandins are a group of lipids that play roles in many body processes such as the regulation of blood flow and inflammation responses. In the context of eye health and conditions such as glaucoma or ocular hypertension, Travatan works by increasing the outflow of aqueous humor (the fluid in our eyes), thereby reducing intraocular pressure - one of the main risk factors for these conditions. Its effect on prostaglandin receptors found predominantly within the eye may also have additional implications on maintaining overall ocular health. Since it does not significantly affect other systems, it is often prescribed when a patient does not respond well to other classes of drugs used for similar purposes (such as beta blockers), or may be combined with them for improved efficacy.
How effective are both Xalatan and Travatan?
Both latanoprost (Xalatan) and travoprost (Travatan) have established histories of success in treating patients with glaucoma, having been approved by the FDA only a few years apart. These medications work on different prostaglandin receptors to increase outflow of aqueous humor from the eye, thereby reducing intraocular pressure which is commonly raised in conditions like glaucoma. The effectiveness of Xalatan and Travatan was directly studied in multiple clinical trials; both drugs exhibit similar efficacy in managing symptoms of elevated intraocular pressure as well as demonstrating promising safety profiles.
A review conducted by Glaucoma Research Foundation reported that latanoprost is effective starting from the first week of treatment, its side effect profile is favorable over many other antiglaucoma medications, and it's well-tolerated even among elderly populations who constitute a majority of glaucoma patients. It has become one of the most widely prescribed medicines for ocular hypertension worldwide due to its once-daily dosing regimen and good tolerability.
On the other hand, several studies indicated that travoprost seems to be more or less equally effective as compared to other common antiglaucoma medications including latanoprost. Nonetheless, some clinicians consider travoprost after failure or intolerance to first-line treatments such as beta blockers or carbonic anhydrase inhibitors because prostaglandins might cause changes like darkening around eyes or growth and darkening eyelashes which are undesirable cosmetic effects for some people.
At what dose is Xalatan typically prescribed?
Dosages of Xalatan, used for the treatment of glaucoma or ocular hypertension, typically consist of one drop in the affected eye(s) once daily in the evening. Studies have indicated that this dosage is sufficient to decrease intraocular pressure in most individuals. Children and adolescents can also be started on the same regimen. In either population, if there is no response after a few weeks, do not increase dose; instead consult your healthcare professional for further advice. It's crucial to remember that exceeding more than one drop per day may result in an increase of intraocular pressure.

At what dose is Travatan typically prescribed?
Travatan treatment is typically initiated with 1 drop in the affected eye(s) once daily in the evening. It should not be administered more than once daily since it has been shown that more frequent administration of prostaglandin analogs may lessen the intraocular pressure lowering effect. If an individual dose is missed, treatment should continue with the next dose as planned. The dosing of Travatan should not exceed once daily to best ensure effective pressure reduction. Treatment can then continue indefinitely as prescribed by your doctor, but if there's no significant response after a few weeks, additional or alternative therapy might be considered.
What are the most common side effects for Xalatan?
Side effects of Xalatan and Travatan, both eye drops used for glaucoma treatment, can include:
- Eye redness or discomfort
- Changes in eyelash growth (increased length, thickness, pigmentation)
- Darkening of the iris color
- Blurred vision
- Burning/stinging/itching/dryness of the eye after administering the drop
- Feeling as if something is in your eye
- Increased sensitivity to light
- Nausea or upset stomach
It's important to note that these side effects are usually mild and temporary. However, should you experience severe discomfort or any changes in vision while using either medication, it is advised to seek immediate medical attention.
Are there any potential serious side effects for Xalatan?
While Xalatan and Travatan are both used to reduce high pressure inside the eye, they may have different side effects. In rare cases, these can include:
- Signs of an allergic reaction such as hives; difficult breathing; swelling of your face, lips, tongue or throat
- Eye pain or discomfort
- Changes in vision, blurred vision
- Redness, burning or itching of the eye
- Darkening of eyelid skin color
- Increased brown pigmentation in the colored part of the eye which may be permanent
More severe but less common side effects could include:
-Unusual changes in heart rate (too fast/slow/irregular) -Chest pain -Swelling hands/ankles/feet. -Dizziness and feeling like you might faint.
If any of these symptoms occur stop using either medication and seek immediate medical attention.
What are the most common side effects for Travatan?
Travatan, another medication for managing glaucoma, may present with different side effects such as:
- Redness or discomfort in the eyes
- Changes in eyelash length and thickness
- Blurred vision
- A sensation of something being stuck in the eye
- Eye itching or stinging immediately upon use
- Dry eyes
- Increased sensitivity to light Remember, like most medications, these side effects are not always experienced by everyone. However, if you experience severe versions of these symptoms while using Travatan, it's essential to consult your healthcare provider promptly.
Are there any potential serious side effects for Travatan?
Travatan is generally well tolerated, but like any medication, it can have side effects. In some instances, these side effects may be serious and require immediate attention:
- Signs of an allergic reaction: difficulty breathing; hives; swelling in your face, lips or throat
- Eye discomfort or severe stinging after using the drops
- Redness, itching or pain in the eyes
- Changes in vision, including blurriness
- Increased sensitivity to light
- Discoloration of the iris (the colored part of your eye)
If you experience any of these symptoms after using Travatan eye drops for glaucoma treatment, contact your healthcare provider immediately. You should also notify your doctor if you notice changes to eyelashes such as increased length, thickness or darkening - a rare but potential effect with chronic use.
Contraindications for Xalatan and Travatan?
Both Xalatan and Travatan, along with most other glaucoma medications, may potentially cause a change in eye color or eyelash length. If you notice any changes to your eyes, consult your doctor immediately.
Neither Xalatan nor Travatan should be used if you are currently taking or have recently taken thimerosal-containing products. Always inform your physician about all the medications you are using; thimerosal-containing products should be stopped for at least 5 minutes prior to administering these drugs to prevent potential interactions.
It's important to note that both these drugs can cause blurred vision temporarily after administration. Hence, it is highly recommended not to drive or operate machinery until the effect has worn off.
As always before starting any medication regimen it's essential that medical history is shared with healthcare providers including allergies because both medications contain benzalkonium chloride which might trigger allergic reactions in susceptible individuals.
How much do Xalatan and Travatan cost?
For the brand name versions of these drugs:
- The price of one bottle (2.5 ml) of Xalatan eye drops averages around $180, which works out to approximately $6/day considering a typical dosage would be one drop in each eye once daily.
- The price for Travatan Z ophthalmic solution (2.5ml) is about $200, working out to roughly $7/day with the same dosage pattern.
Thus, if you are following similar dosages for both drugs, then brand-name Xalatan is less expensive on a per-day treatment basis. Please note that cost should not be your primary consideration in determining which medication is right for you.
For the generic versions of Travatan (Travoprost) and Xalatan (Latanoprost), costs are significantly lower:
- Latanoprost ophthalmic solution can be found as low as $20 - 30 per bottle, reducing the daily cost to around $.80 - 1.20.
- Travoprost generically priced could range from approximately $40 - 50 per bottle bringing down the everyday expense to about $1.60 - 2.
Bear in mind that prices vary based on location and availability; consult your healthcare provider or pharmacist for accurate pricing information.
Popularity of Xalatan and Travatan
Latanoprost, available under the brand name Xalatan among others, was prescribed to nearly 3.5 million people in the US in 2020. Latanoprost is primarily used as a first-line treatment for glaucoma and ocular hypertension and accounted for approximately 28% of prostaglandin analog prescriptions in the US last year. Its use has been consistently growing since it received FDA approval back in 1996.
Travoprost, sold under various brand names such as Travatan Z, had about 1.8 million users across America during the same period. Prescriptions of travoprost represent around 14% of all prostaglandin analog medications issued within that timeframe – just over half compared to latanoprost's numbers. Travaprost is also used for treating high eye pressure (ocular hypertension) or open-angle glaucoma but appears less frequently prescribed than latanoprost due to its higher cost.
Conclusion
Both Xalatan (latanoprost) and Travatan (travoprost) have a long-standing record of usage in patients with glaucoma, and are backed by numerous clinical studies indicating that they are more effective at reducing intraocular pressure than placebo treatments. Both drugs belong to the prostaglandin analogue class of medications, but due to their slightly different mechanisms of action, they can result in varied responses from individual patients.
Xalatan is often considered as a first-line treatment option for open-angle glaucoma or ocular hypertension whereas Travatan may be used when patients do not respond well to other medication or if they need an additional boost in reduction of eye pressure.
Both drugs are available in generic forms which represents significant cost savings especially for patients who must pay out-of-pocket. With both Xalatan and Travatan, the full effects on lowering intraocular pressure might not be seen until after several weeks or even months.
The side effect profile is similar between these two drugs; both being generally well-tolerated but could cause changes such as darkening eye color over time. For both drugs, patients should monitor their vision closely and consult their doctor immediately if there's any noticeable deterioration.
