Levobunolol
Betagan (levobunolol) is a prescription eye drop medication classified as a beta-blocker, used to lower intraocular pressure in patients with glaucoma and ocular hypertension. It reduces pressure in the eye by decreasing the production of fluid (aqueous humor). This medication is typically used when patients need additional pressure control beyond first-line treatments.

Betagan is primarily prescribed to manage elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension, helping to prevent optic nerve damage and vision loss.
As a non-selective beta-blocker, Betagan reduces aqueous humor production in the ciliary body of the eye, thereby lowering intraocular pressure. The active ingredient levobunolol is applied topically as eye drops but can be absorbed systemically.
Betagan is contraindicated in patients with asthma, severe COPD, sinus bradycardia, or heart block. Systemic absorption may cause side effects typical of beta-blockers. Patients should not discontinue abruptly and should inform doctors of all cardiac or respiratory conditions before use. Regular eye pressure monitoring is recommended during treatment.
