Used primarily in the treatment of glaucoma, this compound helps reduce intraocular pressure by inhibiting carbonic anhydrase in the ciliary processes of the eye. This inhibition decreases the secretion of aqueous humor, thereby lowering pressure within the eye and helping to prevent optic nerve damage. It is commonly formulated as a topical ophthalmic suspension for direct application to the eye. Its use is especially beneficial in patients who do not respond adequately to other anti-glaucoma medications. Due to its localized action and minimal systemic absorption, it offers a favorable safety profile with fewer side effects compared to oral carbonic anhydrase inhibitors.
