Which medication is considered a glaucoma agent?

Latanoprost is recognized as a glaucoma agent because it belongs to a class of medications known as prostaglandin analogs. These medications are specifically designed to reduce intraocular pressure in individuals diagnosed with glaucoma, a condition characterized by elevated pressure within the eye that can lead to damage of the optic nerve and loss of vision. Latanoprost works by increasing the outflow of aqueous humor, the fluid within the eye, thus effectively lowering the intraocular pressure.

The other medications listed do not have a direct role in managing glaucoma. Atorvastatin is primarily used to manage cholesterol levels and reduce the risk of cardiovascular disease, while Levothyroxine is a thyroid hormone replacement used in the treatment of hypothyroidism. Metformin is an oral hypoglycemic agent used primarily for managing type 2 diabetes, with no indications for the treatment of glaucoma. Therefore, Latanoprost stands out as the appropriate choice for managing this specific eye condition.
