Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective beta-1 adrenergic receptor antagonist; reduces intraocular pressure by decreasing aqueous humor production.
Selective beta-1 adrenergic receptor antagonist with nitric oxide-mediated vasodilatory activity via stimulation of beta-3 receptors.
Instill 1 drop of 0.5% solution in the affected eye(s) twice daily.
5 mg orally once daily. May be initiated at 2.5 mg in patients with renal impairment or those at risk of hypotension. Titrate at 2-week intervals up to 40 mg once daily.

Terminal elimination half-life: 4–5 hours. With topical ophthalmic administration, systemic absorption is minimal, so half-life refers to IV data.
Terminal elimination half-life: 12-19 hours in extensive metabolizers; up to 30-50 hours in poor CYP2D6 metabolizers; clinically, once-daily dosing is effective due to pharmacodynamic half-life >40 hours.
Renal (fecal <5%). 60% as unchanged drug, 40% as inactive metabolites.
Approximately 38% renal, 48% fecal (unchanged drug and metabolites); extensive hepatic metabolism (CYP2D6) with glucuronidation; <1% excreted unchanged in urine.
