Which of the following statements regarding glaucoma treatment with timolol is true?

Timolol is a non-selective beta-blocker that is primarily used to lower intraocular pressure in patients with glaucoma. The statement indicating that it is used when other medications have failed to control pressure is accurate because timolol is often utilized as part of a treatment regimen for glaucoma when initial treatments are insufficient or not tolerated. This highlights its role in managing chronic conditions where multiple treatment lines may be needed to achieve effective pressure control.

In contrast, timolol is not a steroid medication, which rules out that possibility. While it certainly addresses elevated eye pressure, saying that it only treats this condition overlooks its potential role in broader treatment protocols. Additionally, timolol does not produce immediate effects upon administration; it requires consistent dosing over time to effectively manage intraocular pressure. Thus, the context of timolol’s application highlights its importance in the management of glaucoma, particularly when other treatment strategies do not yield adequate results.
