Which topical ophthalmic beta blocker is known to possibly have neuroprotective properties?

Betaxolol is known to possibly have neuroprotective properties, particularly because it is a selective beta-1 adrenergic antagonist. This selectivity allows it to exert its effects primarily on the heart with fewer side effects on bronchial function as compared to non-selective beta-blockers. Research has suggested that beta-1 blockade may have a protective effect on retinal ganglion cells, which can be beneficial in conditions like glaucoma.

The neuroprotective properties attributed to Betaxolol have gained attention in clinical studies, where it demonstrated the potential to inhibit apoptosis (programmed cell death) in retinal cells and reduce the detrimental effects of increased intraocular pressure on the optic nerve and retinal ganglion cells.

In the context of ocular pharmacology, this characteristic distinguishes Betaxolol from other topical beta-blockers, which may not exhibit the same level of neuroprotective effect on the optic nerve.
