Drug information of Travoprost

Travoprost

Drug group:

Travoprost lowers pressure inside the eye by increasing the amount of fluid that drains from the eye.

Mechanism of effect

Prostaglandin F2-alpha analog; increasing outflow of aqueous humor

A selective FP prostanoid receptor agonist which lowers intraocular pressure by increasing trabecular meshwork and outflow

Pharmacodynamic

Travoprost, an isopropyl ester prodrug, is a synthetic prostaglandin F2 alpha analog that is rapidly hydrolyzed by esterases in the cornea to its biologically active free acid . The travoprost free acid is potent and highly selective for the FP prostanoid receptor

Pharmacokinetics

Metabolism: hydrolyzed by esterases in the cornea

Excretion: urinary; complete systemic elimination within 1 hr

Onset of Action:~2 hours;

 Peak effect: 12 hours

Half-Life Elimination:45 minute

Alerts

-Inadvertent contamination of multiple-dose ophthalmic solutions has caused bacterial keratitis

-Eye color changes

-Intraocular inflammation and exacerbation of inflammation may occur

-Topical prostaglandin analogues have been associated with the occurrence/exacerbation of macular edema

-Use with caution in patients with a history of herpes simplex keratitis; reactivation may occur. Avoid use in patients with active herpes simplex keratitis

-Use cautiously in patients with intraocular inflammation as topical prostaglandins may worsen inflammation

-Use in pediatric patients (<16 years of age) is not recommended by the manufacturer due to possible safety issues of increased pigmentation following long-term chronic use

Points of recommendation

- Remove contact lens prior to instillation

-Wash your hands before using the eye drops.

-tell your doctor if you have ever had:

  • swelling or an infection in your eye;
  • retinal detachment;
  • eye surgery or injury affecting the lens of your eye.

 

Pregnancy level

C

Animal studies have shown teratogenic results. There are no adequate and well-controlled studies in pregnant women.

Ophthalmic prostaglandins, such as travoprost, are generally avoided during pregnancy due to a theoretical risk of miscarriage and premature labor

Breast feeding warning

There are no data on effects on breastfed child or milk production; it is not known if drug is present in human milk following ophthalmic administration

This drug is not recommended unless there are no safer alternatives.
