Pharmacological action of

The anti-glaucoma drug, an analogue of prostaglandin F2 , is a selective agonist of FP receptors (prostaglandin F) and reduces intraocular pressure (IOP) by increasing the outflow of aqueous humor, mainly through the uveoscleral pathway, as well as through the trabecular network.

Installed, that latanoprost does not have a significant effect on the production of aqueous humor and on the hematophthalmic barrier.

When used in therapeutic doses, latanoprost does not have a significant pharmacological effect on the cardiovascular and respiratory systems.

IOP reduction begins approximately 3-4 hours after drug administration, the maximum effect is observed after 8-12 hours, the effect persists for at least 24 hours.

Pharmacokinetics

Absorption

Latanoprost is a prodrug absorbed through the cornea, where it is hydrolyzed ( under the influence of esterases) with the formation of a biologically active acid. Cmax of latanoprost in aqueous humor is achieved approximately 2 hours after topical administration of the drug.

The distribution of

Vd is 0.16 ± 0.02 l / kg. Latanoprost acid is determined in aqueous humor during the first 4 hours, and in plasma - only during the first hour after topical application.

Metabolism

Latanoprost acid, which enters the systemic circulation, is metabolized mainly in the liver by beta-oxidation of fatty acids to form 1,2-dinor and 1,2,3,4-tetranor metabolites.

Excretion

Latanoprost acid is rapidly excreted from plasma: T1 / 2 is 17 min. Systemic clearance is approximately 7 ml / min / kg. After beta oxidation in the liver, metabolites are excreted mainly by the kidneys: after topical application, approximately 88% of the dose is excreted in the urine.

Pharmacokinetics in special clinical cases

Latanoprost exposure is approximately 2 times higher in children aged 3 to 12 years compared with adult patients and 6 times higher in children under 3 years of age. However, the safety profile of the drug is not different in children and adults. The time to reach Cmax of latanoprost acid in blood plasma is 5 minutes for all age groups. T1 / 2 latanoprost acid in children is the same as in adults. In equilibrium concentration, cumulation of latanoprost acid in blood plasma does not occur.

Indications

Decreased increased intraocular pressure (IOP) in adults and children (over 1 year of age) with open-angle glaucoma or increased ophthalmotonus.

Use during pregnancy and lactation

Pregnancy

There have been no adequate controlled studies in pregnant women. The drug should be prescribed during pregnancy only in cases where the potential benefit to the mother outweighs the possible risk to the fetus.

Lactation

Latanoprost and its metabolites may be excreted in breast milk, therefore, during breast-feeding, the drug should be used with caution.

In some patients with significant corneal damage, very rare cases of corneal calcification have been reported due to the use of phosphate-containing eye drops.

The safety profile of Xalatan® in children did not differ from the safety profile in adults. Compared with the adult population, nasopharyngitis and fever were most commonly observed in children.

overdose

Symptoms: In addition to irritation of the mucous membrane of the eye, conjunctival hyperemia or episcleras, other undesirable changes on the part of the organ of view in the overdose of latanoprost are not known. In the case of latanoprost ingestion, the following information should be taken into consideration: one vial of 2.5 ml solution contains 125 μg of latanoprost.
