Used primarily in the treatment of glaucoma, this compound helps reduce intraocular pressure by inhibiting carbonic anhydrase in the ciliary body of the eye. This inhibition decreases the production of aqueous humor, thereby lowering pressure within the eye and helping prevent optic nerve damage. It is commonly formulated as a topical ophthalmic suspension for direct application to the eye. Due to its localized action and minimal systemic absorption, it offers effective pressure control with fewer side effects compared to oral carbonic anhydrase inhibitors. Often prescribed when other therapies are insufficient, it may also be combined with other antiglaucoma medications for enhanced effect.
