What is this medication?
Ophthalmic Alpha2 Agonist; Ophthalmic Beta Blocker
COMBIGAN, the combination of Brimonidine and Timolol (Ophthalmic), is officially indicated to treat elevated intraocular pressure secondary to open angle glaucoma or ocular hypertension who require adjunct or replacement therapy due to uncontrolled intraocular pressure.
How does this medication work?
Brimonidine reduces aqueous humor production and increases uveoscleral outflow via selective alpha2 agonism thereby reducing intraocular pressure.
Timolol reduces intraocular pressure by reducing aqueous humor production and possibly increasing its outflow via blocking both beta1– and beta2-adrenergic receptors.
How should I take this medication?
Ophthalmic: Instill one drop into affected eye(s) twice daily approximately every 12 hours.
