Travoprost is a prostaglandin analog used in ophthalmic care to lower intra-ocular pressure (IOP) in patients with certain types of glaucoma and ocular hypertension. This article covers Travoprost, available as a generic medication and marketed under brand names such as Travatan and Travatan Z. It is supplied as a sterile ophthalmic solution in a 0.004% concentration, packaged in a single-dose or multi-dose bottle. In Hong Kong, travoprost is a prescription-only product regulated by the Department of Health.
Travoprost mimics the activity of prostaglandin F₂α, binding to prostanoid FP receptors located on the ciliary muscle and trabecular meshwork of the eye. Activation of these receptors enhances uveoscleral outflow, the alternative pathway by which aqueous humor drains from the anterior chamber. Increased outflow reduces intra-ocular pressure, helping to prevent optic nerve damage associated with glaucoma.
Because travoprost is administered topically, systemic absorption is minimal, and the drug’s bioavailability is confined to ocular tissues.
Travoprost is approved in Hong Kong for the reduction of elevated intra-ocular pressure in:
These indications are based on clinical studies demonstrating a sustained IOP reduction of approximately 20-30 % compared with baseline measurements. Travoprost is generally prescribed for adult patients; pediatric use is considered only in specialist settings when benefits outweigh risks.
No robust peer-reviewed evidence currently supports off-label indications for travoprost. Consequently, this section is omitted.
These effects are generally mild and may diminish with continued use.
If any severe ocular pain, vision loss, or sudden swelling occurs, seek urgent medical attention.
Because systemic absorption is minimal, systemic drug interactions are not a major concern.

Yes. Travoprost can be administered to each affected eye once daily. Apply one drop to one eye, wait a few minutes, then apply a drop to the other eye to avoid cross-contamination.
Persistent conjunctival hyperemia may be managed with artificial tears or a mild anti-inflammatory eye drop, but you should contact your ophthalmologist to confirm that the reaction is not due to an underlying condition.
Both travoprost and latanoprost are prostaglandin analogs that lower IOP by enhancing uveoscleral outflow. Clinical trials have shown comparable IOP reductions, though individual response can vary; your eye-care professional will select the most appropriate agent for you.
Travoprost is generally safe with contact lenses, but the drop may cause temporary blurry vision. It is advisable to insert lenses after the medication has been absorbed, or remove lenses before dosing and re-insert them later.
Yes. A common side effect is increased eyelash length, thickness, or darkness. This effect is usually mild and reversible after discontinuation of the medication.
Travoprost does not impair cognitive function or motor skills. However, if you experience significant visual disturbances, you should refrain from driving until the issue resolves.
Travoprost may cause transient ocular irritation. Patients with dry eye may benefit from preservative-free artificial tears, used at a different time than the prostaglandin drop.
A standard 5 mL bottle contains approximately 100 drops. At one drop per eye daily, a single bottle can last up to 100 days, though usage frequency should be confirmed with your ophthalmologist.
Safety data in pregnancy are limited. Travoprost should be used only if the potential benefit justifies the potential risk to the fetus, after discussion with a qualified healthcare provider.
Unused or expired travoprost should be placed in a sealed container and disposed of according to local pharmacy or hazardous waste collection programs to prevent accidental exposure.
