Answer

Beta-blockers

Topical beta-adrenergic receptor antagonists decrease aqueous humor production by the ciliary body. Adverse effects of beta-blockers are due to systemic absorption of the drug and include decreased cardiac output and bronchial constriction. In susceptible patients, this may cause bronchospasm, bradycardia, heart block, or hypotension. Pulse rate and blood pressure should be monitored in patients receiving topical beta-blocker therapy, and punctal occlusion may need to be performed after administration of the drops.

Levobunolol (AKBeta, Betagan)

Nonselective beta-adrenergic blocking agent that lowers IOP by reducing aqueous humor production and possibly increases outflow of aqueous humor.

Betaxolol ophthalmic (Betoptic, Betoptic S)

Selectively blocks beta1-adrenergic receptors with little or no effect on beta2-receptors. Reduces IOP by reducing production of aqueous humor.

Timolol maleate (Timoptic, Timoptic XE, Blocadren)

May reduce elevated and normal IOP, with or without glaucoma, by reducing production of aqueous humor or by outflow.
