Levobetaxolol is a drug used to lower the pressure in the eye in treating conditions such as glaucoma. It is marketed as a 0.25 or 0.5% ophthalmic solution of levobetaxolol hydrochloride under the trade name Betaxon. Levobetaxolol is a beta-adrenergic receptor inhibitor (beta blocker).
Betaxolol also shows greater affinity for beta 1 receptors than metoprolol. In addition to its effect on the heart, betaxolol reduces the pressure within the eye (intraocular pressure). This effect is thought to be caused by reducing the production of the liquid (which is called the aqueous humor) within the eye. The precise mechanism of this ...

Brinzolamide (trade name Azopt) is a carbonic anhydrase inhibitor used to lower intraocular pressure in patients with open-angle glaucoma or ocular hypertension. It inhibits a number of isoenzymes, the strongest of which is carbonic anhydrase II (CA-II). The combination of brinzolamide with timolol is marketed under the trade name Azarga.
Is there a link between weight loss drugs and blindness? First, let’s cover a few basics about these medications. Semaglutide is in a class of medications called GLP-1 receptor agonists.
NAION is a very rare eye disease, and it's not an adverse drug reaction listed on the labels for semaglutide in the form of Ozempic, Rybelsus and Wegovy, Novo Nordisk said in a statement.

[3] [14] The mechanism of action of timolol is probably the reduction of the formation of aqueous humor [3] in the ciliary body in the eye. It was the first beta blocker approved for topical use in treatment of glaucoma in the United States (1978). [ 15 ]
