AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
BLOCADREN (timolol maleate) is a non-selective beta-adrenergic receptor antagonist approved in 1981 for reducing elevated intraocular pressure in glaucoma and ocular hypertension. It works by decreasing aqueous humor secretion in the eye, lowering intraocular pressure, which is a major risk factor for optic nerve damage and glaucomatous vision loss. The oral tablet formulation has been a foundational therapy in ophthalmology for over four decades.
