Латанопрост

Описание

Xalatan was launched in Sweden, Switzerland and the US for the treatment of glaucoma. It can be synthesized, from the Corey lactone, using standard prostaglandin chemistry. Latanoprost is a PGF_2α, analog that is more lipophilic thus is better able to penetrate the cornea. The (15R)-diastereomer has only 10% of the activity compared to the (15S)-diastereomer. It is a selective FP receptor agonist with little or no effect on the other prostanoid receptors. The antiglaucoma effects are the result of reduced intraocular pressure arising by increasing uveoscleral outflow with little or no effect on trabeculo-canalicular aqueous outflow and no effect on retinal vasculation or permeability of the blood-aqueous barrier. The topical application is sufficient for a single daily dosage and is well tolerated with no detectible conjunctival hyperaemia.

Использование

Latanoprost is the isopropyl ester of 17-phenyl-13,14-dihydro prostaglandin F2α (17-phenyl-13,14-dihydro PGF2α). It is a prodrug form of the free acid, which is a potent agonist of the FP receptor in the eye. Latanoprost reduces intraocular pressure in glaucoma patients with few side effects. The EC50 value of latanoprost (tested as the free acid) for FP receptors is 3.6 nM.

Определение

ChEBI: A prostaglandin Falpha that is the isopropyl ester prodrug of latanoprost free acid. Used in the treatment of open-angle glaucoma and ocular hypertension.

Общее описание

Latanoprost (Xalatan) is available as a 0.005% sterileophthalmic solution in a 2.5-mL dispenser bottle.Latanoprost is also marketed as a combination ophthalmicproduct with the β-adrenergic blocking agent, timolol,which apparently enhances IOP-lowering by decreasing theproduction of aqueous humor. Cautions and side effects aresimilar to those for other ophthalmic prostanoids.

Профиль безопасности

A poison by ingestion and intravenous route. Human systemic effects. When heated to decomposition it emits acrid smoke and irritating vapors.
