Tavaren
Tavaren Uses, Dosage, Side Effects, Food Interaction and all others data.
Tavaren, an isopropyl ester prodrug, is a synthetic prostaglandin F2 alpha analogue that is rapidly hydrolyzed by esterases in the cornea to its biologically active free acid. The travoporst free acid is potent and highly selective for the FP prostanoid receptor.
Tavaren free acid is a selective FP prostanoid receptor agonist and is believed to reduce intraocular pressure by increasing the drainage of aqueous humor, which is done primarily through increased uveoscleral outflow and to a lesser extent, trabecular outflow facility.

Uses
Tavaren Eye Drops is used for the reduction of elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension who are intolerant of or insufficiently responsive to another intraocular pressure lowering medication, as monotherapy or as adjunctive therapy.
Tavaren is also used to associated treatment for these conditions: Increased Intra Ocular Pressure (IOP)
How Tavaren works
Tavaren, a prostaglandin F2α analogue, is a highly selective full agonist which has a high affinity for the prostaglandin FP receptor, and facilitates reductions in intraocular pressure by increasing the outflow of aqueous humour via trabecular meshwork and uveoscleral pathways . Reduction of the intraocular pressure in man starts about 2 hours after administration and maximum effect is reached after 12 hours. Significant lowering of intraocular pressure can be maintained for periods exceeding 24 hours with a single dose .
Dosage
Tavaren dosage
Use in adults: The recommended dose is one drops of Tavaren in the conjunctival sac of the affected eye (s) once daily in the evening, If more than one topical ophthalmic product is being used, the medicines must be administered at least 5 minutes apart. When substituting another ophthalmic antiglaucoma agent with Tavaren, discontinue the other agent and start the following day with Tavaren.
Pediatric patients: The efficacy and safety of travoprost eye drops in patients below the age of 18 years have not been established.
Side Effects
The most frequently reported treatment-related side-effect is ocular hyperaemia.
Toxicity
No cases of overdose have been reported for travoprost . A topical overdose is not likely to occur or to be associated with toxicity . A topical overdose of travoprost may be flushed from the eye(s) with lukewarm water . Treatment of a suspected oral ingestion is symptomatic and supportive .
Tavaren has harmful pharmacological effects on pregnancy and/or the fetus/new-born child. Tavaren should not be used during pregnancy unless clearly necessary . The medication subsequently must not be used in women of childbearing age/potential unless adequate contraceptive measures are in place .
It is unknown whether travoprost from the eye drops is excreted in human breast milk. Animal studies have shown excretion of travoprost and metabolites in breast milk . The use of travoprost by breast-feeding mothers is not recommended .
There are no data on the effects of TRAVATAN on human fertility . Animal studies showed no effect of travoprost on fertility at doses more than 250 times the maximum recommended human ocular dose .
Use in patients below the age of 16 years is not recommended because of potential safety concerns related to increased pigmentation following long-term chronic use .
No overall clinical differences in safety or effectiveness have been observed between elderly and other adult patients .
Tavaren has been studied in patients with mild to severe hepatic impairment and in patients with mild to severe renal impairment (creatinine clearance as low as 14 ml/min) [L514. No dosage adjustment is necessary for these patients .
Precaution
Tavaren should be used with caution in patients with active intraocular inflammation (iritis/uveitis). Tavaren should not be administered while wearing contact lenses. Contact lenses should be removed prior to the administration of the solution. Lenses may be reinserted 15 minutes following administration of Tavaren.
Interaction
Reduced therapeutic effect with NSAIDs.
Food Interaction
No interactions found.Volume of Distribution
Given the data currently available, it has been recorded that travoprost free acid is moderately distributed into body tissues with a volume of distribution of 2.6 L/kg in rats .
Elimination Route
Tavaren is systemically absorbed through the cornea . In humans, peak plasma concentrations of travoprost free acid were low (25 pg/mL or less) and occurred within 30 minutes following topical ocular administration of one drop of 0.004% travoprost ophthalmic solution .
Half Life
The terminal elimination half-life of travoprost free acid is determined to be approximately 45 minutes, although studies demonstrated half-life values that ranged from 17 to 86 minutes .
Clearance
Data regarding the clearance of travoprost is not readily available or accessible.
Elimination Route
Less than 2% of the topical ocular dose of travoprost was excreted in the urine within 4 hours as the travoprost free acid . Moreover, elimination from plasma is rapid, resulting in concentrations below the limit of quantitation (< 10 pg/mL) by one hour .
Furthermore, in rats, 95% of a subcutaneous radiolabeled dose was eliminated within 24 hours . The major route of elimination was via the bile (61%) with the remainder excreted by the kidneys .
Pregnancy & Breastfeeding use
There are no adequate and well-controlled clinical study En pregnant women. Tavaren should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
It is not known whether the drug or its metabolites are excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when travoprost is administered to a lactating woman.
Contraindication
Tavaren eye drops is contraindicated in patients with hypersensitive to travoprost or any excipients of Tavaren.
