• auxiliary substances: disodium phosphate dodecahydrate - 11.85 mg, sodium dihydrogen phosphate dihydrate - 5.2 mg, sodium chloride - 4.1 mg, benzalkonium chloride - 0.2 mg, 1M sodium hydroxide solution / 1M hydrochloric acid solution - up to pH 6 ± 0.1, purified water.

Pharmacological properties

Pharmacodynamics

Timolol is a non-selective beta-adrenergic receptor blocker, has a slight internal sympathomimetic and membrane-stabilizing activity (SMA). When applied topically, it reduces the formation of aqueous humor and slightly increases its outflow, thereby lowering intraocular pressure.

Latanoprost is an active analogue of prostaglandin F2α, as well as a selective FP receptor agonist. The main mechanism of action of latanoprost is an increase in uveoscleral outflow. By increasing the outflow of aqueous humor, latanoprost thereby lowers intraocular pressure. It has an anti-glaucoma effect, does not have a reliable effect on the production of aqueous humor, and does not affect the hemato-ophthalmic barrier.

Pharmacokinetics

When applied topically, Timolol penetrates the cornea in a short time. In 1 hour after the instillation of drops, the maximum concentration of timolol in the aqueous humor of the eye is reached. The plasma half-life is 6 hours. Through the vessels of the conjunctiva, the mucous membrane of the lacrimal tract and nose, by absorption, it enters the systemic circulation in a small amount. Timolol metabolites are excreted mainly by the kidneys.

Latanoprost reaches its maximum concentration in the aqueous humor of the eye (approximately 15-30 ng / ml) 2 hours after the instillation of drops. Distributed primarily in the eyelids, conjunctiva and anterior segment of the eyes. Only a small amount of matter reaches the posterior segment. In the cornea, under the influence of esterases, latanoprost undergoes hydrolysis with the formation of biologically active acid. In the tissues of the eye, metabolism of latanoprost acid practically does not occur. The main metabolism takes place in the liver. The plasma half-life is 17 minutes. The main metabolites, 1,2-dinor- and 1,2,3,4-tetranor-metabolites, have little or no biological activity, and are excreted mainly in the urine.

• open-angle glaucoma.

With the simultaneous administration of timolol and epinephrine, cases of the development of mydriasis have been described.

Concomitant use of Duoprost with drugs that reduce the activity of catecholamines, slow calcium channel blockers, antiarrhythmics (such as amiodarone, quinidine), beta-blockers, cholinomimetics, cardiac glycosides, monoamine oxidase inhibitors and narcotic analgesic effects can cause an increase / hypotensive effect. bradycardia.
