COMBIGAN Eye Drops (5ml) contain a combination of two active ingredients: brimonidine (an alpha agonist) and timolol (a beta-blocker). These eye drops are used to reduce elevated intraocular pressure in individuals with glaucoma or ocular hypertension. Brimonidine works by reducing the production of eye fluid, while timolol helps decrease fluid production and improves fluid drainage, lowering eye pressure. They are typically used as directed by a healthcare provider.
