Dosage Forms
Excipient information presented when available (limited, particularly for generics); consult specific product labeling.
Solution, Ophthalmic:
Travatan Z: 0.004% (2.5 mL, 5 mL) [benzalkonium free; contains cremophor el, propylene glycol]
Generic: 0.004% (2.5 mL, 5 mL)
Pharmacology
Mechanism of Action
A selective FP prostanoid receptor agonist which lowers intraocular pressure by increasing trabecular meshwork and outflow
Pharmacokinetics/Pharmacodynamics
Absorption
Absorbed via cornea; plasma levels <10 pg/mL within 1 hour
Metabolism
Hydrolyzed by esterases in the cornea to active free acid; systemically; the free acid is metabolized to inactive metabolites
Onset of Action
~2 hours; Peak effect: 12 hours
Half-Life Elimination
45 minutes (range:17 to 86 minutes)
Use in Specific Populations
Special Populations: Race
The IOP-lowering effect was shown to be 7 to 8 mm Hg in clinical studies. The mean IOP reduction in African-American patients was up to 1.8 mm Hg greater than in non-African-American patients. The reason for this effect is unknown.
Use: Labeled Indications
Elevated intraocular pressure: Reduction of elevated intraocular pressure in patients ≥16 years with open-angle glaucoma or ocular hypertension
Contraindications
There are no contraindications listed in the manufacturer’s labeling.
Canadian labeling: Additional contraindications (not in US labeling): Hypersensitivity to travoprost or any component of the formulation; pregnancy or women attempting to become pregnant
Dosage and Administration
Dosing: Adult
Elevated intraocular pressure: Ophthalmic: Instill 1 drop into affected eye(s) once daily in the evening; do not exceed once-daily dosing (may decrease IOP-lowering effect).
Dosing: Geriatric
Refer to adult dosing.
Dosing: Pediatric
Elevated intraocular pressure: Ophthalmic: Children and Adolescents: Limited data available: 1 drop into affected eye(s) once daily in the evening (Yanovich, 2008). Note: Do not exceed once-daily dosing (may decrease IOP-lowering effect).
Administration
May be used with other eye drops to lower intraocular pressure. If using more than one ophthalmic product, wait at least 5 minutes in between application of each medication. Remove contact lenses prior to administration and wait 15 minutes (after administration) before reinserting. Minimize contamination by not touching the eyelids or surrounding areas with the dropper tip; keep bottle tightly closed when not in use.
Storage
Store between 2°C and 25°C (36°F and 77°F).
Drug Interactions
Nonsteroidal Anti-Inflammatory Agents: May diminish the therapeutic effect of Prostaglandins (Ophthalmic). Nonsteroidal Anti-Inflammatory Agents may also enhance the therapeutic effects of Prostaglandins (Ophthalmic). Monitor therapy
Nonsteroidal Anti-Inflammatory Agents (Ophthalmic): May diminish the therapeutic effect of Prostaglandins (Ophthalmic). Nonsteroidal Anti-Inflammatory Agents (Ophthalmic) may enhance the therapeutic effect of Prostaglandins (Ophthalmic). Monitor therapy

Warnings/Precautions
Concerns related to adverse effects:
- Bacterial keratitis: Inadvertent contamination of multiple-dose ophthalmic solutions has caused bacterial keratitis.
- Ocular effects: May permanently change/increase brown pigmentation of the iris, the eyelid skin, and eyelashes. In addition, may increase the length, thickness, and/or number of eyelashes (may vary between eyes); changes occur slowly and may not be noticeable for months or years. Long-term consequences and potential injury to eye are not known.
Disease-related concerns:
- Ocular disease: Use with caution in patients with intraocular inflammation (eg, uveitis), aphakic patients, pseudophakic patients with a torn posterior lens capsule, or patients with risk factors for macular edema. Safety and efficacy have not been determined for use in patients with angle-closure-, inflammatory-, or neovascular glaucoma.
Special populations:
- Contact lens wearers: Remove contact lens prior to instillation; may reinsert 15 minutes following administration.
- Pediatric: Use in pediatric patients (<16 years of age) is not recommended due to possible safety issues of increased pigmentation following long-term chronic use.
Pregnancy
Pregnancy Risk Factor
C
Pregnancy Considerations
Adverse events have been observed in animal reproduction studies following systemic administration. If ophthalmic agents are needed during pregnancy, the minimum effective dose should be used in combination with punctal occlusion to decrease potential exposure to the fetus (Samples 1988).
