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.

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.
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).
[4] [5] In rosacea it improves the redness. [5] It is used as eye drops or applied to the skin. [4] [5] It is also available in the fixed-dose combination medication brimonidine/timolol along with timolol maleate. [6] Common side effects when used in the eyes include itchiness, redness, and a dry mouth. [4]
Betaxolol is most commonly ingested orally alone or with other medications for the management of essential hypertension. [4] It is a cardioselective beta blocker, targeting beta-1 adrenergic receptors found in the cardiac muscle. Blood pressure is decreased by the mechanism of blood vessels relaxing and improving the flow of blood. [5] [6]
Latanoprost is more effective than timolol 0.5% twice daily in 3 of 4 large (n = 163 to 267) randomised, double-blind trials. Latanoprost demonstrated a stable long-term IOP-lowering effect in 1- or 2-year continuations of these trials, with no sign of diminishing effect during prolonged treatment.
