Dorzolamide/timolol, sold under the brand name Cosopt among others, is a medication used to treat high pressure inside the eye including glaucoma. [3] [5] [6] It is a combination of dorzolamide hydrochloride and timolol maleate. [3] It may be used when a beta blocker, like timolol, is not sufficient alone. [7] It is used as an eye drop. [3]
The IOP is higher during sleep. Efficacy of timolol in lowering IOP during the sleep period may be limited. [16] [17] [18] It is a 5–10× more potent beta blocker than propranolol. Timolol is light-sensitive; it is usually preserved with 0.01% benzalkonium chloride (BAC), but also comes BAC-free.
Brimonidine/timolol, sold under the brand name Combigan among others, is a fixed-dose combination medication eye drop used for the treatment of glaucoma. [1] It is a combination of brimonidine (an α 2 adrenergic agonist) and timolol (a β adrenergic blocker).
Because of the timolol component, which is a beta blocker, the drops are contraindicated in people with lung problems such as asthma or severe chronic obstructive pulmonary disease, or with heart problems such as sinus bradycardia (slow heartbeat), sick sinus syndrome, sino-atrial block, or severe atrioventricular block.

Brimonidine is an α 2 adrenergic agonist. [4]Peripheral α 2 agonist activity results in vasoconstriction of blood vessels (as opposed to central α 2 agonist activity that decreases sympathetic tone, as can be seen by the medication clonidine).
While definitive sites of metabolism have not been firmly established, there are several metabolites worthy of note. N-Desethylbrinzolamide is an active metabolite of the parent compound, and thus exhibits carbonic anhydrase inhibitory activity (largely carbonic anhydrase-I, when in the presence of Brinzolamide) and also accumulates in the erythrocytes.
