pharmachologic effect

Dorzopt Plus - a combined drug, has an anti-glaucoma effect. Each of the components reduces intraocular pressure by reducing the secretion of aqueous humor. Dorzolamide - carbonic anhydrase inhibitor; reduces the secretion of intraocular fluid (slowing the formation of bicarbonate, followed by a weakening of the transfer of Na + and water). Does not cause accommodation spasm, miosis, hemeralopia. Timolol is a non-selective beta-adrenoreceptor blocker with a slight internal SMA. When applied topically reduces intraocular pressure by reducing the formation of aqueous humor and a small increase in its outflow.
