Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective beta-1 adrenergic receptor antagonist; reduces heart rate, myocardial contractility, and blood pressure by blocking catecholamine effects.
Selective beta-1 adrenergic receptor antagonist; reduces intraocular pressure by decreasing aqueous humor production.
50 mg orally once daily; may increase to 100 mg orally once daily if needed.
Instill 1 drop of 0.5% solution in the affected eye(s) twice daily.

6-9 hours (terminal elimination half-life); may increase to 15-30 hours in renal impairment (CrCl <35 mL/min).
Clinical Note
moderateAtenolol + Digoxin
"Atenolol may increase the bradycardic activities of Digoxin."
Clinical Note
moderateAtenolol + Digitoxin
"Atenolol may increase the bradycardic activities of Digitoxin."
Clinical Note
moderateAtenolol + Deslanoside
"Atenolol may increase the bradycardic activities of Deslanoside."
Clinical Note
moderateAtenolol + Acetyldigitoxin
"Atenolol may increase the bradycardic activities of Acetyldigitoxin."
Terminal elimination half-life: 4–5 hours. With topical ophthalmic administration, systemic absorption is minimal, so half-life refers to IV data.
Renal: 40-50% unchanged drug; minor hepatic metabolism (10-20%) with biliary excretion of metabolites; <5% fecal.
Renal (fecal <5%). 60% as unchanged drug, 40% as inactive metabolites.
