Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective beta-1 adrenergic receptor antagonist; reduces cardiac output, heart rate, and renin release from kidneys.
Competitive antagonist at beta-1 and beta-2 adrenergic receptors; also blocks alpha-1 adrenergic receptors, causing vasodilation.
Adults: Initial dose 2.5-5 mg orally once daily, titrate to 10 mg once daily; maximum 20 mg once daily.
Initial: 100 mg orally twice daily, titrate to 200-400 mg twice daily; maximum 2400 mg/day. Alternatively, 20 mg IV bolus over 2 minutes, then 40-80 mg IV at 10-minute intervals as needed; IV infusion: 2 mg/min, titrate to response.

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.
Terminal elimination half-life is approximately 6-8 hours in healthy individuals, but may be prolonged in patients with hepatic impairment or severe renal dysfunction (up to 12-16 hours).
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.
Labetalol is extensively metabolized in the liver via glucuronidation; less than 5% of the dose is excreted unchanged in urine. Approximately 55-60% of metabolites are excreted renally, and about 30% in feces via biliary secretion.
