Description of the drug approved by the manufacturer for the printed edition of 2017.


Antiglaucoma combined preparation.

Latanoprost is an analogue of prostaglandin F 2?
and a selective agonist of FP receptors. Reduces intraocular pressure by increasing the outflow of aqueous humor and has anti-glaucoma effect. The main mechanism of action of latanoprost is associated with an increase in uveoscleral outflow. Does not have a significant effect on the production of aqueous humor and does not affect the hemato-ophthalmic barrier.
Timolol is a non-selective blocker of ОІ-adrenoreceptors with a slight internal sympathomimetic and membrane-stabilizing activity.
With topical application lowers the intraocular pressure by reducing the formation of watery moisture and a small increase in its outflow.


Suction and distribution

Cmax in aqueous humor (approximately 15-30 ng / ml) is achieved 2 hours after instillation into the eye.
After the application of eye drops, latanoprost is distributed, first of all, in the anterior segment of the eye, in the conjunctiva and in the eyelids. Only a small amount of the drug reaches the posterior segment. Latanoprost undergoes hydrolysis in the cornea under the action of esterases to form a biologically active acid.
Metabolism and excretion

Metabolism of latanoprost acid in the tissues of the eye practically does not occur.
The main metabolism occurs in the liver. T 1/2 of the plasma is 17 minutes. The main metabolites, 1,2-dinor- and 1,2,3,4-tetranor metabolites, do not or have weak biological activity and are mainly excreted in the urine.

With topical application timolol quickly penetrates through the cornea.
After instillation of eye drops C max timolol in the aqueous humor of the eye is achieved after 1 h.
T 1/2 from the plasma - 6 hours. In an insignificant amount, it enters the systemic bloodstream by absorption through the vessels of the conjunctiva, the nasal mucosa and the lacrimal tract.
The excretion of timolol metabolites is mainly carried out by the kidneys.

- open-angle glaucoma;

increased intraocular pressure.


The drug is used topically.

Bury 1 drop in the eye (a) 1 time / day.
If one dose was missed, then in the future it is necessary to continue treatment, introducing the next dose as usual.
If a patient is assigned more than one preparation for topical administration for an ophthalmic disease, then these drugs should be administered at intervals of not less than 5 minutes.

Caution should be given to the preparation with inflammatory, neovascular, occlusive or congenital glaucoma, open-angle glaucoma in combination with pseudophakia, pigmentary glaucoma (due to lack of sufficient experience in the use of the drug), aphakia, pseudoafakia with a rupture of the posterior capsule of the lens, patients with risk factors for macular edema (in the treatment with latanoprost there are described cases of development of macular edema, including cystoid).


Adequate and strictly controlled clinical studies on the safety of the drug during pregnancy and lactation (breastfeeding) was not conducted.

The use of the drug in pregnancy is possible only if the intended benefit to the mother exceeds the potential risk to the fetus or child.

The drug should not be given to breastfeeding women, or breastfeeding should be abandoned (timolol, latanoprost and its metabolites can enter breast milk).


Contraindicated in the use of drugs under the age of 18 years.


The drug can cause a gradual change in eye color by increasing the amount of brown pigment in the iris, periodic monitoring of the treating physician is recommended.

The drug contains a preservative of benzalkonium chloride, which can be absorbed by contact lenses and have a damaging effect on the eye tissue.
Therefore, it is necessary to remove contact lenses and re-install them 15 minutes after instillation.
Impact on the ability to drive vehicles and manage mechanisms

Burying eye drops can cause a transient feeling of "shroud before your eyes" for several minutes, which should be taken into account when driving a car and working with moving mechanisms.
While this effect does not disappear, patients should not drive a car or use sophisticated technology.

Symptoms: due to latanoprost - eye irritation, conjunctival or episcleral hyperemia, dizziness;
caused by timolol - headache, arrhythmia, bradycardia, bronchospasm, nausea, vomiting.
Treatment: immediately flush eyes with water or 0.9% sodium chloride solution, symptomatic therapy.


With simultaneous application with slow calcium channel blockers, drugs that reduce the activity of catecholamines, beta-blockers, antiarrhythmics (including amiodarone and quinidine), cardiac glycosides, cholinomimetics, opioid analgesics and MAO inhibitors, hypotensive effect and / or development of severe bradycardia may be enhanced.

With the simultaneous use of timolol with epinephrine, mydriasis sometimes developed.
