Answer

Beta-adrenergic blockers

The exact mechanism of ocular antihypertensive action is not established, but it appears to be a reduction of aqueous humor production or inhibition of inflow.

Timolol ophthalmic (Timoptic XE, Timoptic, Blocadren)

May reduce elevated and normal IOP with or without glaucoma by inhibiting inflow.

Levobunolol (AKBeta, Betagan)

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

Betaxolol ophthalmic (Betoptic)

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