Final answer:
Timolol and Betaxolol have neuroprotective properties. Among the options provided, the drug with known neuroprotective properties is:(C) Betaxolol
Step-by-step explanation:
Neuroprotective properties are abilities of drugs to protect neurons from damage or degeneration. Among the given options, Timolol and Betaxolol have been found to have neuroprotective properties. These drugs belong to the class of beta-blockers. They work by blocking beta receptors associated with vasoconstriction and cardioacceleration, and in the process, they can protect neurons from damage and improve cardiac function. Betaxolol is a beta-blocker, and it is often used to treat glaucoma. Studies suggest that betaxolol may have neuroprotective effects, particularly on retinal ganglion cells, making it a drug of interest in conditions affecting the optic nerve. Timolol and metipranolol are also beta-blockers commonly used in the treatment of glaucoma, while brimonidine is an alpha-2 adrenergic agonist with intraocular pressure-lowering effects but is not typically considered to have significant neuroprotective properties.
