ATENOLOL vs CARTROL
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.
CARTROL is a beta-1 selective adrenergic receptor antagonist. It inhibits the effects of catecholamines on beta-1 receptors in the heart, reducing heart rate, myocardial contractility, and blood pressure.
50 mg orally once daily; may increase to 100 mg orally once daily if needed.
Adults: 2.5 mg orally twice daily, titrated up to maximum 10 mg 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 + Deslanoside
"Atenolol may increase the bradycardic activities of Deslanoside."
Clinical Note

Terminal elimination half-life is 6–8 hours in normal renal function; prolonged to 20–40 hours in severe renal impairment (CrCl <30 mL/min).
Renal: 40-50% unchanged drug; minor hepatic metabolism (10-20%) with biliary excretion of metabolites; <5% fecal.
Primarily renal excretion (approx. 70% unchanged drug), with 20% biliary/fecal, and 10% metabolism to inactive metabolites.
