Which medication is specifically indicated for lowering intraocular pressure in glaucoma?

All of the medications listed are indicated for lowering intraocular pressure in the treatment of glaucoma.

Dorzolamide is a carbonic anhydrase inhibitor that decreases aqueous humor production, leading to a reduction in intraocular pressure. It is often used as a topical eye drop, making it a vital option for glaucoma management.

Brimonidine is an alpha agonist that reduces aqueous humor production and increases uveoscleral outflow, contributing to lower intraocular pressure as well. It can also be used in combination with other medications for enhanced effectiveness.

Timolol Maleate is a non-selective beta-blocker that lowers intraocular pressure by decreasing aqueous humor production. It is one of the most commonly used medications for managing chronic open-angle glaucoma.

Since all these medications have established efficacy in lowering intraocular pressure, they collectively represent the correct answer, indicating that multiple effective options are available for glaucoma treatment.
