carteolol is a non-selective beta-adrenergic receptor antagonist used to treat intraocular pressure associated with ocular hypertension and glaucoma. The mechanism of action of carteolol is to block the beta-adrenergic receptors located in the ciliary epithelium and the ciliary muscle in the eye, leading to a reduction in aqueous humor production and an increase in aqueous humor outflow. This results in a decrease in intraocular pressure.
carteolol ophthalmic is effective against open-angle and closed-angle glaucoma, the most common forms. It also effectively treats ocular hypertension, an elevated intraocular pressure without evidence of optic nerve damage or visual field loss. carteolol ophthalmic is available as eye drops administered topically to the eye.
