Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Beta-1 selective beta-adrenergic receptor antagonist; reduces intraocular pressure by decreasing aqueous humor production.
Selective beta-1 adrenergic receptor antagonist; reduces cardiac output, heart rate, and renin release from kidneys.
Instill 1 drop of 0.25% or 0.5% solution into the affected eye(s) twice daily.
Adults: Initial dose 2.5-5 mg orally once daily, titrate to 10 mg once daily; maximum 20 mg once daily.

Terminal elimination half-life is approximately 10-15 hours in adults; prolonged in renal impairment (up to 30 hours).
Terminal elimination half-life is 9–12 hours (mean 11 hours), allowing once-daily dosing. Half-life may be prolonged in renal impairment (creatinine clearance <40 mL/min) and in elderly patients.
Primarily renal excretion of unchanged drug and metabolites; about 80% eliminated in urine, 20% in feces as unchanged drug or glucuronide conjugates.
Approximately 50% excreted unchanged in urine; remainder metabolized in liver to inactive metabolites, then renally excreted. Fecal excretion is negligible (<2%). Total renal clearance accounts for ~60-70% of elimination.
